Wicket Authorization Using MetaDataKey
- by JGirl
I am trying to implement a simple authorization strategy for my Wicket application. I am implemented my own AuthorizationStrategy (extending IAuthorizationStrategy).
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.
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;
}
}
I add it a component
public static MetaDataKey priv = new MetaDataKey() {};
editLink.setMetaData(priv, new RoleCheck("Update"));
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) {
...
}
}
However the getMetaData gives an error
"Bound mismatch: The generic method getMetaData(MetaDataKey) of type Component is not applicable for the arguments (MetaDataKey). The inferred type RoleCheck is not a valid substitute for the bounded parameter "
Any help would be appreciated. Thank you
