Day209-整合SSM

综合之前学的MyBatis、Spring和SpringMVC，整合了一个简单案例——图书管理系统，练习CURD增删改查

整合SSM：ssmbuild

1、环境要求

• IDEA

• MySQL 5.7

• Tomcat 9

• Maven 3.6

2、数据库环境

创建一个存放书籍数据的数据库表

 CREATE DATABASE `ssmbuild`;
 ​
 USE `ssmbuild`;
 ​
 DROP TABLE IF EXISTS `books`;
 ​
 CREATE TABLE `books` (
     `bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
     `bookName` VARCHAR(100) NOT NULL COMMENT '书名',
     `bookCounts` INT(11) NOT NULL COMMENT '数量',
     `detail` VARCHAR(200) NOT NULL COMMENT '描述',
     KEY `bookID` (`bookID`)
 ) ENGINE = INNODB DEFAULT CHARSET = utf8;
 ​
 INSERT INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
 (1,'Java',20,'从入门到放弃'),
 (2,'MySQL',10,'从删库到跑路'),
 (3,'Linux',5,'从进门到坐牢');

 

效果：

 

3、基本环境搭建

1、新建一个无模板Maven项目ssmbuild，添加web的支持

2、导入相关的pom依赖

 <!--    依赖：junit、数据库驱动、连接池、Servlet、jsp、mybatis、mybatis-spring、spring-->
 <dependencies>
     <dependency>
         <groupId>junit</groupId>
         <artifactId>junit</artifactId>
         <version>4.12</version>
     </dependency>
     <dependency>

         <artifactId>mysql-connector-java</artifactId>
         <version>5.1.47</version>
     </dependency>
     <!--        数据库连接池-->
     <dependency>
         <groupId>com.mchange</groupId>
         <artifactId>c3p0</artifactId>
         <version>0.9.5.2</version>
     </dependency>
 ​
     <dependency>
         <groupId>javax.servlet</groupId>
         <artifactId>servlet-api</artifactId>
         <version>2.5</version>
     </dependency>
     <dependency>
         <groupId>javax.servlet.jsp</groupId>
         <artifactId>jsp-api</artifactId>
         <version>2.2</version>
     </dependency>
     <dependency>
         <groupId>javax.servlet</groupId>
         <artifactId>jstl</artifactId>
         <version>1.2</version>
     </dependency>
 ​
     <dependency>
         <groupId>org.mybatis</groupId>
         <artifactId>mybatis</artifactId>
         <version>3.5.2</version>
     </dependency>
     <dependency>
         <groupId>org.mybatis</groupId>
         <artifactId>mybatis-spring</artifactId>
         <version>2.0.6</version>
     </dependency>
 ​
     <dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-webmvc</artifactId>
         <version>5.2.8.RELEASE</version>
     </dependency>
     <dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-jdbc</artifactId>
         <version>5.2.8.RELEASE</version>
     </dependency>
     
     <dependency>
         <groupId>org.projectlombok</groupId>
         <artifactId>lombok</artifactId>
         <version>1.18.16</version>
     </dependency>
 </dependencies>

 

3、Maven资源过滤设置

<!--    静态资源导出问题-->
 <build>
     <resources>
         <resource>
             <directory>src/main/java</directory>
             <includes>
                 <include>**/*.properties</include>
                 <include>**/*.xml</include>
             </includes>
             <filtering>false</filtering>
         </resource>
         <resource>
             <directory>src/main/resources</directory>
             <includes>
                 <include>**/*.properties</include>
                 <include>**/*.xml</include>
             </includes>
             <filtering>false</filtering>
         </resource>
     </resources>
 </build>

 

4、建立基本结构和配置框架

创建文件夹子目录

• pojo 实体类对象，与数据库字段一一对应

• dao 直接操作数据库，调用SQL语句

• service 实现具体业务，调用dao层

• controller 实现前端与后端的交互，调用service层

配置文件

• mybatis-config.xml

 <?xml version="1.0" encoding="UTF8" ?>
 <!DOCTYPE configuration
         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
         "http://mybatis.org/dtd/mybatis-3-config.dtd">
 <configuration>
     <settings>
         <setting name="logImpl" value="STDOUT_LOGGING"/>
     </settings>
     
 <!--配置数据源交由Spring去做-->
     <typeAliases>
         <package name="com.zhou.pojo"/>
     </typeAliases>
 ​
     <mappers>
         <mapper class="com.zhou.dao.BookMapper"/>
     </mappers>
 </configuration>

 

• database.properties，需要加上jdbc前缀

 jdbc.driver=com.mysql.jdbc.Driver
 jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8
 jdbc.username=root
 jdbc.password=root

5、总的配置文件

applicationContext.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
         https://www.springframework.org/schema/beans/spring-beans.xsd">
 ​
     <import resource="spring-dao.xml"/>
     <import resource="spring-service.xml"/>
     <import resource="spring-mvc.xml"/>
 ​
 </beans>

 

6、打开项目配置Project Structure

 

 

 

7.连接数据库

 

 

 

4、MyBatis层

4.1、配置文件修改

mybatis-config.xml

 <?xml version="1.0" encoding="UTF8" ?>
 <!DOCTYPE configuration
         PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
         "http://mybatis.org/dtd/mybatis-3-config.dtd">
 <configuration>
 <!--配置数据源交由Spring去做-->
     <typeAliases>
         <package name="com.zhou.pojo"/>
     </typeAliases>
 ​
     <mappers>
         <mapper class="com.zhou.dao.BookMapper"/>
     </mappers>
 </configuration>

 

4.2、子目录实现

2.1、pojo Books实体类

 package com.zhou.pojo;
 ​
 import lombok.AllArgsConstructor;
 import lombok.Data;
 import lombok.NoArgsConstructor;
 import lombok.ToString;
 ​
 /**
  * @Name Books
  * @Description 书本实体类
  * @Author 88534
  * @Date 2021/9/16 22:26
  */
 @Data
 @AllArgsConstructor
 @NoArgsConstructor
 @ToString
 public class Books {
     private int BookID;
     private String bookName;
     private int bookCounts;
     private String detail;
 }

 

2.2、dao BookMapper接口

package com.zhou.dao;

import com.zhou.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

/**
 * @Name BookMapper
 * @Description
 * @Author 88534
 * @Date 2021/9/16 22:29
 */
public interface BookMapper {
    /**
     * 增加一本书
     * @param books
     * @return
     */
    int addBook(Books books);

    /**
     * 删除一本书
     * @param id
     * @return
     */
    int deleteBookById(@Param("bookId") int id);

    /**
     * 更新一本书
     * @param books
     * @return
     */
    int updateBook(Books books);

    /**
     * 查询一本书
     * @param id
     * @return
     */
    Books queryBookById(@Param("bookId") int id);

    /**
     * 查询全部的书
     * @return
     */
    List<Books> queryAllBooks();
}

 

2.3、dao层 BookMapper.xml

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zhou.dao.BookMapper">

    <insert id="addBook" parameterType="Books">
        insert into ssmbuild.books (bookName, bookCounts, detail)
        values (#{bookName},#{bookCounts},#{detail});
    </insert>

    <delete id="deleteBookById" parameterType="int">
        delete from ssmbuild.books where bookID = #{bookId};
    </delete>

    <update id="updateBook" parameterType="Books">
        update ssmbuild.books set bookName = #{bookName}, bookCounts = #{bookCounts}, detail = #{detail}
        where bookId = #{bookId};
    </update>

    <select id="queryBookById" resultType="Books">
        select * from ssmbuild.books
        where bookID = #{bookId};
    </select>

    <select id="queryAllBooks" resultType="Books">
        select * from ssmbuild.books;
    </select>

</mapper>

 

2.4、service BookService接口

与Mapper相比，不需要前后交互，去掉@Param注解

package com.zhou.service;

import com.zhou.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

/**
 * @Name BookService
 * @Description
 * @Author 88534
 * @Date 2021/9/16 22:29
 */
public interface BookService {
    /**
     * 增加一本书
     * @param books
     * @return
     */
    int addBook(Books books);

    /**
     * 删除一本书
     * @param id
     * @return
     */
    int deleteBookById(int id);

    /**
     * 更新一本书
     * @param books
     * @return
     */
    int updateBook(Books books);

    /**
     * 查询一本书
     * @param id
     * @return
     */
    Books queryBookById(int id);

    /**
     * 查询全部的书
     * @return
     */
    List<Books> queryAllBooks();
}

 

2.5、service BookServiceImpl实现类

package com.zhou.service;

import com.zhou.dao.BookMapper;
import com.zhou.pojo.Books;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

/**
 * @Name BookServiceImpl
 * @Description service调用dao层，组合dao
 * @Author 88534
 * @Date 2021/9/16 22:50
 */
public class BookServiceImpl implements BookService{

    @Autowired
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    @Override
    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    @Override
    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

    @Override
    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    @Override
    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    @Override
    public List<Books> queryAllBooks() {
        return bookMapper.queryAllBooks();
    }
}

 

5、Spring层

5.1、配置Spring整合dao层（Mybatis）

数据源使用c3p0连接池

编写相关配置文件spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">

    <!--    1.关联数据库配置文件-->
    <context:property-placeholder location="classpath:database.properties"/>

    <!--    2.连接池-->
<!--    dbcp:半自动化操作，不能自动连接
        c3p0:自动化操作（自动化的加载配置文件，并且可以自动设置到对象中
        druid
        hikari
        -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<!--        配置连接池属性-->
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
<!--        c3p0的私有属性-->
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
<!--        关闭连接后不自动commit-->
        <property name="autoCommitOnClose" value="false"/>
<!--        获取连接超时时间-->
        <property name="checkoutTimeout" value="10000"/>
<!--        当获取连接失败时重试次数-->
        <property name="acquireRetryAttempts" value="2"/>
    </bean>

    <!--    3.sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--        注入数据库连接池c3p0-->
        <property name="dataSource" ref="dataSource"/>
<!--        绑定mybatis配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>

<!--    配置dao接口扫描包，动态实现了Dao接口可以注入到Spring容器中，取代了SQLSession-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!--        给出需要扫描Dao接口包-->
        <property name="basePackage" value="com.zhou.dao"/>
    </bean>
</beans>

 

5.2、配置Spring整合service层

spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">

<!--   1.扫描service下的包-->
    <context:component-scan base-package="com.zhou.service"/>

<!--    2.将所有的业务类注入到Spring，可以通过配置或者注解实现-->
    <bean id="BookServiceImpl" class="com.zhou.service.BookServiceImpl">
        <property name="bookMapper" ref="bookMapper"/>
    </bean>

<!--    3.声明式事务配置-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!--        注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>

</beans>

 

Spring就是一个大容器，对所有资源进行bean管理

6、SpringMVC层

需要让整个项目添加web支持，生成web.xml

6.1、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

<!--    DispatcherServlet-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!--            加载总的配置文件-->
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--    乱码过滤-->
    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

<!--    session过期时间-->
    <session-config>
        <session-timeout>15</session-timeout>
    </session-config>

</web-app>

 

6.2、配置Spring整合controller层

配置spring-mvc.xml

对应视图解析器创建jsp文件夹，盛放前端页面

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc 
        https://www.springframework.org/schema/mvc/spring-mvc.xsd">

<!--    1.注解驱动-->
    <mvc:annotation-driven/>

<!--    2.静态资源过滤-->
    <mvc:default-servlet-handler/>

<!--    3.扫描包：controller-->
    <context:component-scan base-package="com.zhou.controller"/>

<!--    4.视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

 

配置文件，暂时结束！框架已经搭好了，只需要编写对应的dao、service、controller和前端页面即可

接下来的开发顺序为后端到前端的路线，自底向上

---

7、dao层（与数据库打交道）

7.1、bootMapper接口

搜集所有需要调取数据库的操作

package com.zhou.dao;

import com.zhou.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

/**
 * @Name BookMapper
 * @Description
 * @Author 88534
 * @Date 2021/9/16 22:29
 */
public interface BookMapper {
    /**
     * 增加一本书
     * @param books
     * @return
     */
    int addBook(Books books);

    /**
     * 删除一本书
     * @param id
     * @return
     */
    int deleteBookById(@Param("bookID") int id);

    /**
     * 更新一本书
     * @param books
     * @return
     */
    int updateBook(Books books);

    /**
     * 查询一本书
     * @param id
     * @return
     */
    Books queryBookById(@Param("bookID") int id);

    /**
     * 查询全部的书
     * @return
     */
    List<Books> queryAllBooks();

    /**
     * 根据书名查书籍
     * @param bookName
     * @return
     */
    Books queryBookByName(String bookName);
}

 

7.2、bookMapper.xml

编写相应操作的sql语句，设置调用和返回的参数类型

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.zhou.dao.BookMapper">

    <insert id="addBook" parameterType="Books">
        insert into ssmbuild.books (bookName, bookCounts, detail)
        values (#{bookName},#{bookCounts},#{detail});
    </insert>

    <delete id="deleteBookById" parameterType="int">
        delete from ssmbuild.books where bookID = #{bookID};
    </delete>

    <update id="updateBook" parameterType="Books">
        update ssmbuild.books set bookName = #{bookName}, bookCounts = #{bookCounts}, detail = #{detail}
        where bookId = #{bookID};
    </update>

    <select id="queryBookById" resultType="Books">
        select * from ssmbuild.books
        where bookID = #{bookID};
    </select>

    <select id="queryAllBooks" resultType="Books">
        select * from ssmbuild.books;
    </select>

    <select id="queryBookByName" resultType="Books">
        select * from ssmbuild.books where bookName = #{bookName};
    </select>

</mapper>

 

8、service层（处理dao）

8.1、bookService接口

搜集所有的业务，调用dao进行处理

package com.zhou.service;

import com.zhou.pojo.Books;
import java.util.List;

/**
 * @Name BookService
 * @Description
 * @Author 88534
 * @Date 2021/9/16 22:29
 */
public interface BookService {
    /**
     * 增加一本书
     * @param books
     * @return
     */
    int addBook(Books books);

    /**
     * 删除一本书
     * @param id
     * @return
     */
    int deleteBookById(int id);

    /**
     * 更新一本书
     * @param books
     * @return
     */
    int updateBook(Books books);

    /**
     * 查询一本书
     * @param id
     * @return
     */
    Books queryBookById(int id);

    /**
     * 查询全部的书
     * @return
     */
    List<Books> queryAllBooks();

    /**
     * 按名字查书籍
     * @param bookName
     * @return
     */
    Books queryBookByName(String bookName);
}

 

8.2、实现类bookServiceImpl

@Autowired自动注入dao对象BookMapper

package com.zhou.service;

import com.zhou.dao.BookMapper;
import com.zhou.pojo.Books;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

/**
 * @Name BookServiceImpl
 * @Description service调用dao层，组合dao
 * @Author 88534
 * @Date 2021/9/16 22:50
 */
public class BookServiceImpl implements BookService{

    @Autowired
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    @Override
    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    @Override
    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

    @Override
    public int updateBook(Books books) {
        return bookMapper.updateBook(books);
    }

    @Override
    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    @Override
    public List<Books> queryAllBooks() {
        return bookMapper.queryAllBooks();
    }

    @Override
    public Books queryBookByName(String bookName) {
        return bookMapper.queryBookByName(bookName);
    }
}

 

9、Controller层（实现页面跳转）

调用service层

package com.zhou.controller;

import com.zhou.pojo.Books;
import com.zhou.service.BookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.ArrayList;
import java.util.List;

/**
 * @Name BookController
 * @Description
 * @Author 88534
 * @Date 2021/9/17 14:22
 */
@Controller
@RequestMapping("/book")
public class BookController {
    /**
     * controller层调用service层
     */
    @Autowired
    @Qualifier("BookServiceImpl")
    private BookService bookService;

    /**
     * 查询全部的书籍，并且返回到一个书籍展示页面
     * @param model
     * @return
     */
    @RequestMapping("/allBook")
    public String list(Model model){
        List<Books> list = bookService.queryAllBooks();
        model.addAttribute("list",list);
        return "allBook";
    }

    /**
     * 跳转到增加书籍页面
     * @return
     */
    @RequestMapping("/toAddBook")
    public String toAddPage(){
        return "addBook";
    }

    /**
     * 添加书籍的请求
     * @param books
     * @return
     */
    @RequestMapping("/addBook")
    public String addBook(Books books){
        System.out.println("addBook=>" + books);
        bookService.addBook(books);
        //重定向到@RequestMapping("/allBook")请求
        return "redirect:/book/allBook";
    }

    /**
     * 跳转到修改页面
     * @param id
     * @param model
     * @return
     */
    @RequestMapping("/toUpdate")
    public String toUpdatePaper(int id, Model model){
        Books books = bookService.queryBookById(id);
        model.addAttribute("QBook",books);
        return "updateBook";
    }

    /**
     * 修改书籍的需求
     * @param books
     * @return
     */
    @RequestMapping("/updateBook")
    public String updateBook(Books books){
        System.out.println("updateBook=>" + books);
        bookService.updateBook(books);
        return "redirect:/book/allBook";
    }

    /**
     * 删除书籍
     * @param id
     * @return
     */
    @RequestMapping("/deleteBook/{bookID}")
    public String deleteBook(@PathVariable("bookID") int id){
        bookService.deleteBookById(id);
        return "redirect:/book/allBook";
    }

    /**
     * 查询书籍
     * @param queryBookName
     * @param model
     * @return
     */
    @RequestMapping("/queryBook")
    public String queryBook(String queryBookName, Model model){
        Books books = bookService.queryBookByName(queryBookName);
        System.err.println("queryBook=>" + books);
        List<Books> list = new ArrayList<>();

        if (books == null){
            model.addAttribute("error","未查到相关信息");
            list = bookService.queryAllBooks();
        } else {
            list.add(books);
        }
        model.addAttribute("list",list);

        return "allBook";
    }
}

 

10、视图层（前端页面）

前端BootStrap可视化布局

https://www.bootcss.com/p/layoutit/

直接拖动模块生成jsp代码，可以作为简单框架补充用，后续style样式自己编写

10.1、首页index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
  <head>
    <title>首页</title>
    <style>
      a{
        text-decoration: none;
        color: black;
        font-size: 18px;
      }
      h3{
        width: 180px;
        height: 38px;
        margin: 100px auto;
        text-align: center;
        line-height: 38px;
        background: deepskyblue;
        border-radius: 5px;
      }
    </style>
  </head>
  <body>
  <h3>
    <a href="${pageContext.request.contextPath}/book/allBook">进入全部书籍页面</a>
  </h3>
  </body>
</html>

 

效果：
