SSM 整合测试
目录
项目源码：https://gitee.com/menghe999/ssmDemo
0、开始之前
软件环境: IDEA2018.3、 Maven3.5.3、 Tomcat 9.0.37、
建库建表：
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',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');
1、创建Maven项目并加入web支持（在项目上右键->Add Frameworks Support）
2、依赖导入（注意资源过滤）

各层的主要作用
dao主要操作数据库数据pojo （plain ordinaty java object）数据对象原型service此层主要用于处理包含多个pojo对象（也就是数据表），进行事务管理（声明式事务管理），service层（其接口的实现类）被注入多个dao对象，以完成其数据操作。controller主要用于和前端进行数据交互。
4、Mybatis 层
数据库连接配置
database.properties
这个文件主要配置数据连接的必须的参数
jdbc.driver=com.mysql.jdbc.Driver
#如果使用mysql 8.0+ 需要加时区设置 &serverTimezone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=111111
Mybatis核心配置文件
mybatis-config.xml
mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--配置数据源，交给spring-->
<typeAliases>
<package name="com.example.pojo"/>
</typeAliases>
<mappers>
<!--两种配置方式都可以-->
<mapper class="com.example.dao.BookMapper"/>
<!--<mapper resource="com/example/dao/BookMapper.xml"/>-->
</mappers>
</configuration>
实体类的编写（ 依赖lombok）
Books.java
package com.example.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {
private int bookID;
private String bookName;
private int bookCounts;
private String detail;
}
编写dao层的 Mapper接口
BookMapper.java
package com.example.dao;
import com.example.pojo.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
public interface BookMapper {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(@Param("bookId") int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(@Param("bookId") int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
//查询书籍
Books queryBookByName(@Param("bookName") String bookName);
}
编写接口对应的 Mapper.xml 文件。需要导入MyBatis的包
BookMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.dao.BookMapper">
<!--增加一个Book-->
<insert id="addBook" parameterType="Books">
insert into ssmbuild.books(bookName,bookCounts,detail)
values (#{bookName}, #{bookCounts}, #{detail})
</insert>
<!--根据id删除一个Book-->
<delete id="deleteBookById" parameterType="int">
delete from ssmbuild.books where bookID=#{bookID}
</delete>
<!--更新Book-->
<update id="updateBook" parameterType="Books">
update ssmbuild.books
set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
where bookID = #{bookID}
</update>
<!--根据id查询,返回一个Book-->
<select id="queryBookById" resultType="Books">
select * from ssmbuild.books
where bookID = #{bookID}
</select>
<!--查询全部Book-->
<select id="queryAllBook" resultType="Books">
SELECT * from ssmbuild.books
</select>
<!--根据Name查询Book-->
<select id="queryBookByName" resultType="Books">
select * from ssmbuild.books where bookName = #{bookName}
</select>
</mapper>
编写Service层的接口和实现类
BookService.java
package com.example.service;
import com.example.pojo.Books;
import org.apache.ibatis.annotations.Param;
import java.util.List;
//BookService:底下需要去实现,调用dao层
public interface BookService {
//增加一个Book
int addBook(Books book);
//根据id删除一个Book
int deleteBookById(int id);
//更新Book
int updateBook(Books books);
//根据id查询,返回一个Book
Books queryBookById(int id);
//查询全部Book,返回list集合
List<Books> queryAllBook();
Books queryBookByName(String bookName);
}
BookServiceImpl.java
package com.example.service;
import com.example.dao.BookMapper;
import com.example.pojo.Books;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class BookServiceImpl implements BookService {
// service 调用dao 组合dao
//调用dao层的操作，设置一个set接口，方便Spring管理
private BookMapper bookMapper;
public void setBookMapper(BookMapper bookMapper) {
this.bookMapper = bookMapper;
}
public int addBook(Books book) {
return bookMapper.addBook(book);
}
public int deleteBookById(int id) {
return bookMapper.deleteBookById(id);
}
public int updateBook(Books books) {
return bookMapper.updateBook(books);
}
public Books queryBookById(int id) {
return bookMapper.queryBookById(id);
}
public List<Books> queryAllBook() {
return bookMapper.queryAllBook();
}
public Books queryBookByName(String bookName) {
return bookMapper.queryBookByName(bookName);
}
}
5、Spring层
需要适配以下要求
- 接管数据库连接
- 配置数据源
- 整合Mybatis（dao、service）
spring-dao.xml 编写 关联数据库、配置数据源c3p0
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
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
https://www.springframework.org/schema/context/spring-context.xsd">
<!--dao-->
<!--关联数据库文件-->
<!--通过spring关联数据库-->
<context:property-placeholder location="classpath:database.properties"/>
<!--连接池
dbcp : 半自动化,不能自动连接
c3p0 :自动化操作
druid
hikari(spring boot 2.x +)
-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<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连接池的私有属性 -->
<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"/>
<!-- 当获取连接失败重试次数 -->
<property name="acquireRetryAttempts" value="2"/>
</bean>
<!--sqlSessionFactory-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>
<!--配置dao接口,动态的实现-->
<!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 -->
<!--解释 ：https://www.cnblogs.com/jpfss/p/7799806.html-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!-- 给出需要扫描Dao接口包 -->
<property name="basePackage" value="com.example.dao"/>
</bean>
</beans>
spring-service.xml 的编写
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
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 扫描service相关的bean-->
<context:component-scan base-package="com.example.service"/>
<!--BookServiceImpl注入到IOC容器中 controller层的Bean注入依赖这里-->
<bean id="BookServiceImpl" class="com.example.service.BookServiceImpl">
<property name="bookMapper" ref="bookMapper"/>
</bean>
<!--注入数据源-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 可扩展 aop事务支持-->
</beans>
6、Spring-mvc层
此层主要用于controller层和前端的交互细节
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">
<!--DispatchServlet-->
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--过滤器 避免乱码-->
<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>
<!--过滤所有的url-->
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<session-config>
<session-timeout>15</session-timeout>
</session-config>
</web-app>
spring-mvc.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:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://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">
<!-- 配置SpringMVC -->
<!-- 1.开启SpringMVC注解驱动 -->
<mvc:annotation-driven />
<!-- 2.静态资源默认servlet配置-->
<mvc:default-servlet-handler/>
<!--3.配置jsp 显示ViewResolver视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<!-- 4.扫描web相关的bean -->
<context:component-scan base-package="com.example.controller"/>
</beans>
最后的配置文件 spring 的 applicationContext.xml 将整合以上dao service mvc
<?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
http://www.springframework.org/schema/beans/spring-beans.xsd">
<import resource="classpath:spring-dao.xml"/>
<import resource="classpath:spring-service.xml"/>
<import resource="classpath:spring-mvc.xml"/>
</beans>
项目模块属性
基本的配置文件编写结束，接下来实现具体的业务（CURD）
7、业务实现层 controller
后端
controller.java
package com.example.controller;
import com.example.pojo.Books;
import com.example.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;
@Controller
@RequestMapping("/book")
public class BookController {
//controller --> service
@Autowired
@Qualifier("BookServiceImpl")
// 注：@Autowired 经常与 Qualifier 配合使用，用于Bean的注入
private BookService bookService;
//查询全部书籍
@RequestMapping("/allBook")
public String list(Model model){
List<Books> list = bookService.queryAllBook();
model.addAttribute("list", list);
return "allBook";
}
@RequestMapping("/toAddBook")
public String toAddPaper() {
return "addBook";
}
@RequestMapping("/addBook")
public String addPaper(Books books) {
System.out.println(books);
bookService.addBook(books);
return "redirect:/book/allBook";
}
@RequestMapping("/toUpdateBook")
public String toUpdateBook(Model model, int id) {
Books books = bookService.queryBookById(id);
System.out.println(books);
model.addAttribute("book",books );
return "updateBook";
}
@RequestMapping("/updateBook")
public String updateBook(Model model, Books book) {
System.out.println(book);
bookService.updateBook(book);
Books books = bookService.queryBookById(book.getBookID());
model.addAttribute("books", books);
return "redirect:/book/allBook";
}
@RequestMapping("/del/{bookId}")
public String deleteBook(@PathVariable("bookId") int id) {
bookService.deleteBookById(id);
return "redirect:/book/allBook";
}
//查询
@RequestMapping("/queryBook")
public String queryBook(String queryBookName,Model model){
Books books = bookService.queryBookByName(queryBookName);
List<Books> list = new ArrayList<Books>();
list.add(books);
if(books== null){
//如果未查到 显示全部书籍
return "redirect:/book/allBook";
}
model.addAttribute("list", list);
return "allBook";
}
}
前端

8、测试
配置Tomcat（因端口占用的问题配置为 10088），启动测试
运行测试
9、需要注意
-
项目开始的时候，创建lib目录并加入Library Files
-
web.xml 的servlet 配置注意，配置为applicationContext.xml
