1. pom 依赖替换

mybatis依赖

<properties>
        <org.mybatis.version>3.4.1</org.mybatis.version>
       <org.mybatis.spring.version>1.3.0</org.mybatis.spring.version>
    </properties>
    
  <!--spring myabtis 整合 Start-->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>${org.mybatis.spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>${org.mybatis.version}</version>
        </dependency>
        <!--spring myabtis 整合 End-->

替换为

<!--spring myabtisPlus 整合 Start-->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus</artifactId>
            <version>3.3.1.tmp</version>
        </dependency>
        <!--spring myabtisPlus 整合 End-->

2. 扫描包

这个一样的，必须要有

<bean name="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.gblfy.dao"/>
    </bean>

3. pom 依赖替换

mybatis

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="mapperLocations" value="classpath*:mapper/*Mapper.xml"></property>
 </bean>

替换为

<!--更新为 myabtisplus-->
    <bean id="sqlSessionFactory" class="com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="mapperLocations" value="classpath*:mapper/*Mapper.xml"></property>
    </bean>

4. dao层接口继承 extends BaseMapper

public interface UserMapper extends BaseMapper<User> {
}
