Error creating bean with name 'indexController': Unsatisfied dependency expressed through field 'use

报错：Error creating bean with name 'indexController': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'UserService': Unsatisfied dependency expressed through field 'userMapper';

 

可能出错的地方

1.没有在serviceImpl标明注解@service

2.serives和serviceImpl没有对应的方法

3.xml中方法的参数类型paramterType不对

parameterType="java.lang.Integer" resultMap="UserResultMap">
     select id,userName,password from USER  where id=#{id}
