mybatis和mybatis-plus同时使用问题处理

问题：原项目基于mybatis开发，新功能基于mybatis-plus开发，同时依赖如下两个jar包

mybatis-spring-boot-starter

mybatis-plus-boot-starter

启动时报错：java.lang.NoClassDefFoundError: org/mybatis/logging/LoggerFactory，详情如下：

Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [com/baomidou/mybatisplus/autoconfigure/MybatisPlusAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sqlSessionFactory' threw exception; nested exception is java.lang.NoClassDefFoundError: org/mybatis/logging/LoggerFactory

解决方法：

1、移除mybatis-spring-boot-starter依赖

2、更新依赖（idea中在pom.xml文件上右键,执行maven->reload project）

启动后错Invalid bound statement (not found)

解决方法：

将服务配置文件中mybatis.mapper-locations的配置挪到mybatis-plus下，其它配置不变，样例如下：

原配置如下：

mybatis:
    mapperLocations: classpath:mapper/**/*.xml

新配置:

mybatis-plus:
  mapperLocations: classpath:mapper/**/*.xml,classpath:/mybatis-plus/*.xml

主要就是在解决从mybatis切换到mybatis-puls后，使用了BaseMapper的用户mapper接口与XXXmapper.xml文件方法绑定的问题，为使用了BaseMapper的用户mapper接口在内存中生成xml映射文件
