关于生成代码启动后 Subject does not have permission的问题

当把生成的代码放在相应的目录之后，点击商品管理看到的菜单是这样的，没有其他的按钮: img[//cdn.renren.io/97825201810261504028861.png] 此时，后台的报错是这样的: r.common.exception.RRExceptionHandler : Subject does not have permission [generator:goods:list] org.apache.shiro.authz.UnauthorizedException: Subject does not have permission [generator:goods:list] at org.apache.shiro.authz.ModularRealmAuthorizer.checkPermission(ModularRealmAuthorizer.java:323) at org.apache.shiro.mgt.AuthorizingSecurityManager.checkPermission(AuthorizingSecurityManager.java:137) at org.apache.shiro.subject.support.DelegatingSubject.checkPermission(DelegatingSubject.java:209) at org.apache.shiro.authz.aop.PermissionAnnotationHandler.assertAuthorized(PermissionAnnotationHandler.java:74) at org.apache.shiro.authz.aop.AuthorizingAnnotationMethodInterceptor.assertAuthorized(AuthorizingAnnotationMethodInterceptor.java:84) at org.apache.shiro.authz.aop.AnnotationsAuthorizingMethodInterceptor.assertAuthorized(AnnotationsAuthorizingMethodInterceptor.java:100) at org.apache.shiro.authz.aop.AuthorizingMethodInterceptor.invoke(AuthorizingMethodInterceptor.java:38) 请问是什么原因？？
