前言

根据自己的环境参考狂神的视频进行了SSM框架整合,用于备忘

SSM框架整合步骤

1. 创建数据库

3. 导入依赖 jnuit 数据库驱动 数据库连接 Severlet JSp

4. maven 资源过滤

  95.

5. 创建两个项目的目录结构以及Spring 和 Mybatis的配置文件

IDEA SSM框架整合配置及步骤详解

  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"
  4. xsi:schemaLocation="http://www.springframework.org/schema/beans
  5. http://www.springframework.org/schema/beans/spring-beans.xsd">
  6.  
  7. </beans>
  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.  
  7. </configuration>

Mybatis

6. 配置数据库属性

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

7. 创建Book实体类(使用lombok插件),编写Dao层mapper接口,在mybatis配置中注册mapper

  1. package com.projectname.pojo;
  2.  
  3. import lombok.AllArgsConstructor;
  4. import lombok.Data;
  5. import lombok.NoArgsConstructor;
  6.  
  7. @Data
  8. @AllArgsConstructor
  9. @NoArgsConstructor
  10. public class Book {
  11. private int bookID;
  12. private String bookName;
  13. private int bookCounts;
  14. private String detail;
  15.  
  16. }
  1. package com.projectname.dao;
  2.  
  3. import com.projectname.pojo.Book;
  4.  
  5. import java.util.List;
  6.  
  7. public interface DaoBook {
  8. //增加一个Book
  9. int addBook(Book book);
  10.  
  11. //根据id删除一个Book
  12. int deleteBookById(int id);
  13.  
  14. //更新Book
  15. int updateBook(Book books);
  16.  
  17. //根据id查询,返回一个Book
  18. Book queryBookById(int id);
  19.  
  20. //查询全部Book,返回list集合
  21. List<Book> queryAllBook();
  22. }
  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">
  5.  
  6. <mapper namespace="com.kuang.dao.BookMapper">
  7.  
  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>
  13.  
  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>
  18.  
  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>
  25.  
  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>
  31.  
  32. <!--查询全部Book-->
  33. <select id="queryAllBook" resultType="Books">
  34. SELECT * from ssmbuild.books
  35. </select>
  36.  
  37. </mapper>
  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. <mappers>
  7. <mapper resource="com/projectname/dao/BookMapper.xml"/>
  8. </mappers>
  9. </configuration>

8. 编写service层的接口和实现类代码

  1. package com.projectname.service;
  2.  
  3. import com.projectname.pojo.Book;
  4.  
  5. import java.util.List;
  6.  
  7. public interface BookService {
  8. //增加一个Book
  9. int addBook(Book book);
  10. //根据id删除一个Book
  11. int deleteBookById(int id);
  12. //更新Book
  13. int updateBook(Book books);
  14. //根据id查询,返回一个Book
  15. Book queryBookById(int id);
  16. //查询全部Book,返回list集合
  17. List<Book> queryAllBook();
  18. }
  1. package com.projectname.service;
  2.  
  3. import com.projectname.dao.BookMapper;
  4. import com.projectname.pojo.Book;
  5.  
  6. import java.util.List;
  7.  
  8. public class BookServiceImpl implements BookService {
  9.  
  10. //调用dao层的操作,设置一个set接口,方便Spring管理
  11. private BookMapper bookMapper;
  12.  
  13. public void setBookMapper(BookMapper bookMapper) {
  14. this.bookMapper = bookMapper;
  15. }
  16.  
  17. public int addBook(Book book) {
  18. return bookMapper.addBook(book);
  19. }
  20.  
  21. public int deleteBookById(int id) {
  22. return bookMapper.deleteBookById(id);
  23. }
  24.  
  25. public int updateBook(Book books) {
  26. return bookMapper.updateBook(books);
  27. }
  28.  
  29. public Book queryBookById(int id) {
  30. return bookMapper.queryBookById(id);
  31. }
  32.  
  33. public List<Book> queryAllBook() {
  34. return bookMapper.queryAllBook();
  35. }
  36. }

Spring

9. 使用Spring编写Mybatis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"
  4. xmlns:context="http://www.springframework.org/schema/context"
  5. 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">
  6. <context:property-placeholder location="classpath:database.properties"/>
  7. <!-- 2.数据库连接池 -->
  8. <!--数据库连接池
  9. dbcp 半自动化操作 不能自动连接
  10. c3p0 自动化操作(自动的加载配置文件 并且设置到对象里面)
  11. -->
  12. <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
  13. <!-- 配置连接池属性 -->
  14. <property name="driverClass" value="${jdbc.driver}"/>
  15. <property name="jdbcUrl" value="${jdbc.url}"/>
  16. <property name="user" value="${jdbc.username}"/>
  17. <property name="password" value="${jdbc.password}"/>
  18. <!-- c3p0连接池的私有属性 -->
  19. <property name="maxPoolSize" value="30"/>
  20. <property name="minPoolSize" value="10"/>
  21. <!-- 关闭连接后不自动commit -->
  22. <property name="autoCommitOnClose" value="false"/>
  23. <!-- 获取连接超时时间 -->
  24. <property name="checkoutTimeout" value="10000"/>
  25. <!-- 当获取连接失败重试次数 -->
  26. <property name="acquireRetryAttempts" value="2"/>
  27. </bean>
  28. <!-- 3.配置SqlSessionFactory对象 -->
  29. <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  30. <!-- 注入数据库连接池 -->
  31. <property name="dataSource" ref="dataSource"/>
  32. <!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
  33. <property name="configLocation" value="classpath:mybatis-configuration.xml"/>
  34. </bean>
  35. <!-- 4.配置扫描Dao接口包,动态实现Dao接口注入到spring容器中 -->
  36. <!--解释 :https://www.cnblogs.com/jpfss/p/7799806.html-->
  37. <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  38. <!-- 注入sqlSessionFactory -->
  39. <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
  40. <!-- 给出需要扫描Dao接口包 -->
  41. <property name="basePackage" value="com.projectname.dao"/>
  42. </bean>
  43. </beans>

  5. 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">
  6.  
  7. <!-- 扫描service相关的bean -->
  8. <context:component-scan base-package="com.projectname.service" />
  9.  
  10. <!--BookServiceImpl注入到IOC容器中-->
  11. <bean id="BookServiceImpl" class="com.projectname.service.BookServiceImpl">
  12. <property name="bookMapper" ref="bookMapper"/>
  13. </bean>
  14.  
  15. <!-- 配置事务管理器 -->
  16. <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  17. <!-- 注入数据库连接池 -->
