错误提示：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'permissionController': Unsatisfied dependency expressed through field 'permissionService'; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'permissionServiceImpl': Bean with name 'permissionServiceImpl' has been injected into other beans [permissionServiceImpl] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesForType' with the 'allowEagerInit' flag turned off, for example.

}
return list;
}
}错误原因：在PermissionServiceImpl实现类中自动注入PermissionService接口，自己调用自己，导致无法注入。
