错误：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'roleService': Unsatisfied dependency expressed through field 'baseMapper': No qualifying bean of type [com.shsxt.base.BaseMapper] is defined: expected single matching bean but found 2: roleMapper,userRoleMapper; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [com.shsxt.base.BaseMapper] is defined: expected single matching bean but found 2: roleMapper,userRoleMapper
错误结构
Service对象创建失败的原因是，service和controller继承了baseservice和basecontroller，但是mapper没有继承basemapper（自己封装的三个base包都要继承 ）也就缺失了basemapper对应的XML文件，导致service对象创建失败
正确的结构
