SSM的环境配置

环境要求

环境：
  • IDEA
  • MySQL5.5
  • Tomcat 8
  • Maven 3.6
要求：
  • 需要熟练掌握MySQL数据库，Spring，JavaWeb及MyBatis知识，简单的前端知识；

 数据库环境

  1. CREATE DATABASE `ssmbuild`;
  3. USE `ssmbuild`;
  5. DROP TABLE IF EXISTS `books`;
  7. CREATE TABLE `books` (
  8. `bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
  9. `bookName` VARCHAR(100) NOT NULL COMMENT '书名',
  10. `bookCounts` INT(11) NOT NULL COMMENT '数量',
  11. `detail` VARCHAR(200) NOT NULL COMMENT '描述',
  12. KEY `bookID` (`bookID`)
  13. ) ENGINE=INNODB DEFAULT CHARSET=utf8
  15. INSERT INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
  16. (1,'Java',1,'从入门到放弃'),
  17. (2,'MySQL',10,'从删库到跑路'),
  18. (3,'Linux',5,'从进门到进牢');

基本环境搭建

  • 新建一Maven项目!，project目录上右键 -> Add Frameworks Support -> Web Application

导入相关的pom依赖！(当前项目使用)

Maven资源过滤设置：pom.xml中添加

  1. <build>
  2. <resources>
  3. <resource>
  4. <directory>src/main/java</directory>
  5. <includes>
  6. <include>**/*.properties</include>
  7. <include>**/*.xml</include>
  8. </includes>
  9. <filtering>false</filtering>
  10. </resource>
  11. <resource>
  12. <directory>src/main/resources</directory>
  13. <includes>
  14. <include>**/*.properties</include>
  15. <include>**/*.xml</include>
  16. </includes>
  17. <filtering>false</filtering>
  18. </resource>
  19. </resources>
  20. </build>

Mybatis与maven不兼容问题：pom.xml中的build中添加（读者无需添加）

  1. <plugins>
  2. <plugin>
  3. <groupId>org.apache.maven.plugins</groupId>
  4. <artifactId>maven-surefire-plugin</artifactId>
  5. <version>2.22.2</version>
  6. <configuration>
  7. <skipTests>true</skipTests>
  8. </configuration>
  9. </plugin>
  10. </plugins>

注意事项：如果maven项目不是使用骨架创建，需要额外导入依赖的jar包，否则会报找不到class文件异常

导入方式：file->project structure->artifacts->output layout->WEB-INF下创建lib并点击add copy of（一个+号按钮）导入所有jar包

建立基本结构和配置框架！

  • com.kuang.pojo

  • com.kuang.mapper

  • com.kuang.service

  • com.kuang.controller

mybatis-config.xml
  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE configuration
  3. PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  4. "http://mybatis.org/dtd/mybatis-3-config.dtd">

Mybatis层编写

1、数据库配置文件 database.properties
  1. jdbc.driver=com.mysql.jdbc.Driver
  2. jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8
  3. jdbc.username=root
  4. jdbc.password=root
2、IDEA关联数据库
3、编写MyBatis的核心配置文件
  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE configuration
  3. PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  4. "http://mybatis.org/dtd/mybatis-3-config.dtd">
  5. <configuration>
  6. <settings>
  7. <setting name="logImpl" value="LOG4J"/>
  8. </settings>
  10. <typeAliases>
  11. <package name="com.kuang.pojo"/>
  12. </typeAliases>
  14. <mappers>
  15. <package name="com.kuang.mapper"/>
  16. </mappers>
  17. </configuration>
4、编写数据库对应的实体类 com.kuang.pojo.Books

使用lombok插件！

  1. package com.kuang.pojo;
  3. import lombok.Data;
  5. @Data
  6. public class Books {
  7. private int bookID;
  8. private String bookName;
  9. private int bookCounts;
  10. private String detail;
  11. }
5、编写Dao层的 Mapper接口！
  1. package com.kuang.mapper;
  2. import com.kuang.pojo.Books;
  3. import java.util.List;
  5. public interface BookMapper {
  6. //增加一个Book
  7. int addBook(Books book);
  9. //根据id删除一个Book
  10. int deleteBookById(int id);
  12. //更新Book
  13. int updateBook(Books books);
  15. //根据id查询,返回一个Book
  16. Books queryBookById(int id);
  18. //查询全部Book,返回list集合
  19. List<Books> queryAllBook();
  20. }
6、编写接口对应的 BookMapper.xml 文件。需要导入MyBatis的包
  1. <?xml version="1.0" encoding="UTF-8" ?>
  2. <!DOCTYPE mapper
  3. PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
  4. "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
  6. <mapper namespace="com.kuang.mapper.BookMapper">
  8. <!--增加一个Book-->
  9. <insert id="addBook" parameterType="Books">
  10. insert into ssmbuild.books(bookName,bookCounts,detail)
  11. values (#{bookName}, #{bookCounts}, #{detail})
  12. </insert>
  14. <!--根据id删除一个Book-->
  15. <delete id="deleteBookById" parameterType="int">
  16. delete from ssmbuild.books where bookID=#{bookID}
  17. </delete>
  19. <!--更新Book-->
  20. <update id="updateBook" parameterType="Books">
  21. update ssmbuild.books
  22. set bookName = #{bookName},bookCounts = #{bookCounts},detail = #{detail}
  23. where bookID = #{bookID}
  24. </update>
  26. <!--根据id查询,返回一个Book-->
  27. <select id="queryBookById" resultType="Books">
  28. select * from ssmbuild.books
  29. where bookID = #{bookID}
  30. </select>
  32. <!--查询全部Book-->
  33. <select id="queryAllBook" resultType="Books">
  34. SELECT * from ssmbuild.books
  35. </select>
  37. </mapper>
7、编写Service层的接口和实现类

接口：

  1. package com.kuang.service;
  2. import com.kuang.pojo.Books;
  4. import java.util.List;
  6. public interface BookService {
  7. //增加一个Book
  8. int addBook(Books book);
  9. //根据id删除一个Book
  10. int deleteBookById(int id);
  11. //更新Book
  12. int updateBook(Books books);
  13. //根据id查询,返回一个Book
  14. Books queryBookById(int id);
  15. //查询全部Book,返回list集合
  16. List<Books> queryAllBook();
  17. }

实现类：

  1. package com.kuang.service.impl;
  3. import com.kuang.mapper.BookMapper;
  4. import com.kuang.pojo.Books;
  5. import com.kuang.service.BookService;
  7. import java.util.List;
  9. public class BookServiceImpl implements BookService {
  11. //调用dao层的操作，后面用自动注入
  12. private BookMapper bookMapper;
  14. public int addBook(Books book) {
  15. return bookMapper.addBook(book);
  16. }
  18. public int deleteBookById(int id) {
  19. return bookMapper.deleteBookById(id);
  20. }
  22. public int updateBook(Books books) {
  23. return bookMapper.updateBook(books);
  24. }
  26. public Books queryBookById(int id) {
  27. return bookMapper.queryBookById(id);
  28. }
  30. public List<Books> queryAllBook() {
  31. return bookMapper.queryAllBook();
  32. }
  33. }
OK，到此，底层需求操作编写完毕！

Spring层

1、配置Spring整合MyBatis，我们这里数据源使用c3p0连接池；
2、我们去编写Spring整合Mybatis的相关的配置文件；spring-dao.xml
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"
  3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  14. <!-- 2.数据库连接池 -->
  15. <!--数据库连接池
  16. dbcp 半自动化操作 不能自动连接
  17. c3p0 自动化操作（自动的加载配置文件 并且设置到对象里面）
  18. -->
  19. <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
  20. <!-- 配置连接池属性 -->
  21. <property name="driverClass" value="${jdbc.driver}"/>

  23. <property name="user" value="${jdbc.username}"/>
  24. <property name="password" value="${jdbc.password}"/>
  26. <!-- c3p0连接池的私有属性 -->
  27. <property name="maxPoolSize" value="30"/>
  28. <property name="minPoolSize" value="10"/>
  29. <!-- 关闭连接后不自动commit -->
  30. <property name="autoCommitOnClose" value="false"/>
  31. <!-- 获取连接超时时间 -->
  32. <property name="checkoutTimeout" value="10000"/>
  33. <!-- 当获取连接失败重试次数 -->
  34. <property name="acquireRetryAttempts" value="2"/>
  35. </bean>
  37. <!-- 3.配置SqlSessionFactory对象 -->
  38. <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  39. <!-- 注入数据库连接池 -->
  40. <property name="dataSource" ref="dataSource"/>
  41. <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
  42. <property name="configLocation" value="classpath:mybatis-config.xml"/>
  43. </bean>
  45. <!-- 4.配置扫描Dao接口包，动态实现Dao接口注入到spring容器中 -->
  46. <!--解释 ：https://www.cnblogs.com/jpfss/p/7799806.html-->
  47. <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  48. <!-- 注入sqlSessionFactory -->
  49. <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
  50. <!-- 给出需要扫描mapper接口包 -->
  51. <property name="basePackage" value="com.kuang.mapper"/>
  52. </bean>
  54. </beans>
3、Spring整合service层
  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <beans xmlns="http://www.springframework.org/schema/beans"

  10. import java.util.List;
  12. @Controller
  13. @RequestMapping("/book")
  14. public class BookController {
  15. @Autowired
  16. private BookService bookService;
  18. @RequestMapping("/allBook")
  19. public String list(Model model) {

  17. line-height: 38px;
  18. background: deepskyblue;
  19. border-radius: 4px;
  20. }
  21. </style>
  22. </head>
