org .springframework .beans .factory .UnsatisfiedDependencyException 怎么解决,我的包又问题吗?

报错如下:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userController': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userServiceImpl': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userMapper' defined in file [C:\Java\Idea_Projects\demo\portal\target\classes\cn\td\portal\mapper\UserMapper.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

你这个是根据表生成代码的吧，

Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required
这才是你的问题

类上的注解加了没
