我报的错:

　　org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sqlSessionFactory‘ defined in class path resource [config/spring/applicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 

这个可能是项目刚开始时导入了mapper文件，但还是没有实体类与其对应而报的错，可以把mapper文件先去掉，这样不报错了

Error creating bean with name 'sqlSessionFactory' defined in class path resource [config/spring/applicationContext.xml]: Invocation of init method failed;
