首先：spring整合MyBatis是出现这个错误：
Exception in thread "main" org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'userMapper': Error creating bean with name 'sqlSessionFactory': Lookup method resolution failed
原因：maven版本问题，jkd版本与spring和mybaits的版本不配置
报错解决：
