在ssm基础上简单整合mybatis-plus

pom.xml

将mybatis和myabtis-spring依赖换成myabtis-plus的依赖

由于之前没有写测试类，这里要测试需要把spring-test依赖加上

<!--<dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis</artifactId>
      <version>3.4.0</version>
    </dependency>
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis-spring</artifactId>
      <version>1.3.0</version>
    </dependency>-->

    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>4.3.12.RELEASE</version>
    </dependency>

    <dependency>
      <groupId>com.baomidou</groupId>
      <artifactId>mybatis-plus</artifactId>
      <version>3.3.2</version>
    </dependency>

applicationContext.xml

将sql会话工厂的class修改成mybatisPlus的

<!--会话工厂-->
<!--<bean class="org.mybatis.spring.SqlSessionFactoryBean" id="sqlSessionFactory" >-->
<bean class="com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean" id="sqlSessionFactory">
       <property name="dataSource" ref="dataSource"></property>
       <property name="typeAliasesPackage" value="cn.lyd.domain"></property>
       <property name="mapperLocations" value="classpath:cn/lyd/mapper/*Mapper.xml"></property>
