Spring + SpringMVCM + Mybatis 整合
一、 通过idea创建maven工程
二、 引入依赖项以及导入mybatis逆向工程的插件
将如下的文件替换所在工程的pom文件
<?xml version="1.0" encoding="UTF-8"?>

三、 配置web.xml
由于这里有两个 spring的配置文件,一个是Springmvc的配置文件一个是spring的配置文件所以
配置时将其改成了spring*.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- 这里 因为有两个spring的配置文件一个是springmvc的一个是 spring的所以在这里 写成了这样的。-->
<param-value>classpath:/spring*.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>
</web-app>
四、 配置springMVC.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"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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">
<!-- 开启包扫描-->
<context:component-scan base-package="com.atguigu"></context:component-scan>
<!--开启springmvc的注解驱动-->
<mvc:annotation-driven/>
<!--开启静态资源拦截-->
<mvc:default-servlet-handler/>
</beans>
五、 配置 spring.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"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"
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 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
<!-- 加载配置文件-->
<context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>
<!-- 开启数据源连接-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
<!--3.配置事务管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!--4.开启事务注解-->
<tx:annotation-driven/>
<!--5.Spring整合Mybatis-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--引入数据源-->
<property name="dataSource" ref="dataSource"/>
<!--配置别名包-->
<property name="typeAliasesPackage" value="com.atguigu.pojo"/>
<!--引入mybatis配置文件-->
<property name="configLocation" value="classpath:/mybatis-config.xml"/>
<!--引入映射文件-->
<property name="mapperLocations" value="classpath:/mapper/*.xml"></property>
</bean>
<!--6.让spring为mapper接口创建代理对象 -->
<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.atguigu.mapper"/>
</bean>
</beans>
六、 通过Mybatis逆向工程生成持久层代码
找到当前项目的 maven
插件 中的 Plugins
中的 mybatis-generator
进行双击
当运行成功之后会生成 三个文件夹和类
