检票授权使用MetaDataKey [英] Wicket Authorization Using MetaDataKey

问题描述

我想实现我的Wicket应用程序一个简单的授权策略。我实现我自己的AuthorizationStrategy（扩大IAuthorizationStrategy）。

I am trying to implement a simple authorization strategy for my Wicket application. I am implemented my own AuthorizationStrategy (extending IAuthorizationStrategy).

看完上面的链接后，我想这更有意义，使用元数据驱动的授权，与使用注解。

http://old.nabble.com/Authorization-strategy-help-td18948597.html After reading the above link, I figured it makes more sense to use metadata-driven authorization than one using Annotations.

所以我有一个简单的RoleCheck类

So I have a simple RoleCheck class

public class RoleCheck {

 private String privilege;

 public RoleCheck(String priv) {
  this.privilege = priv;
 }

 public void setPrivilege(String privilege) {
  this.privilege = privilege;
 }

 public String getPrivilege() {
  return privilege;
 }
}

我添加组件：

public static MetaDataKey<RoleCheck> priv = new MetaDataKey<RoleCheck>() {};
editLink.setMetaData(priv, new RoleCheck("Update"));

在我的授权策略类，我试图让与组件相关的元数据：

And in my Authorization Strategy class, I try to get the metadata associated with the component:

public boolean isActionAuthorized(Component component, Action action) {
  if (action.equals(Component.RENDER)) {
      RoleCheck privCheck = (RoleCheck) component.getMetaData(EditControlToolBar.priv);
      if (privCheck != null) {
           ...
      }
}

但可用getMetaData给出了一个错误

However the getMetaData gives an error

三寸不匹配：通用方法的getMetaData（MetaDataKey＆LT; M＆GT;）的
  键入组件不适用于参数
  （ MetaDataKey＆LT; RoleCheck＆GT; ）。该推断的类型 RoleCheck 不是
  为界参数有效替代品

"Bound mismatch: The generic method getMetaData(MetaDataKey<M>) of type Component is not applicable for the arguments (MetaDataKey<RoleCheck>). The inferred type RoleCheck is not a valid substitute for the bounded parameter "

任何帮助将是AP preciated。谢谢

Any help would be appreciated. Thank you

推荐答案

您RoleCheck类应该实现Serializable接口。

Your RoleCheck class should implement Serializable.

和您使用的检票1.4吗？在这种情况下，我会建议在进行这样的：

And are you using Wicket 1.4 ? In which case I'd suggest proceeding this way :

public class RolePermissionKey extends MetaDataKey<RoleCheck> {
    public static final RolePermissionKey KEY = new RolePermissionKey();
}

要它添加到componenet：

To add it to a componenet :

editLink.setMetaData(RolePermissionKey.KEY, new RoleCheck("Update"));

和执行权限：

RoleCheck privCheck = component.getMetaData(RolePermissionKey.KEY)
