集成mybatis-plus，sqlSessionFactory改为MybatisSqlSessionFactoryBean后，项目无法启动

 <bean id="sqlSessionFactory" class="com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean">

报错信息：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'adminActivityController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'adminActivityServiceImpl': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'ActivityInfoMapper' defined in file [D:\develop\XXXX\mapper\GctivityInfoMapper.class]: 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/XXX/web/config/ApplicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse config resource: class path resource [com/XXX/web/XXX/SqlMapConfig.xml]; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing SQL Mapper Configuration.

解决方案：

将mybatis指定的配置文件删除

<mapper resource="com/xxx/mybatis/mapper/ActivityInfoMapper.xml"/>
