Annotation Type RequiresRoles


@Target(value={TYPE,METHOD})
@Retention(value=RUNTIME)
public @interface RequiresRoles

Requires the currently executing Subject to have all of the specified roles. If they do not have the role(s), the method will not be executed and an AuthorizationException is thrown.

For example,

@RequiresRoles("aRoleName");
void someMethod();

means someMethod() could only be executed by subjects who have been assigned the 'aRoleName' role.

*Usage Note*: Be careful using this annotation if your application has a dynamic security model where roles can be added and deleted at runtime. If your application allowed the annotated role to be deleted during runtime, the method would not be able to be executed by anyone (at least until a new role with the same name was created again).

If you require such dynamic functionality, only the RequiresPermissions annotation makes sense - Permission types will not change during runtime for an application since permissions directly correspond to how the application's functionality is programmed (that is, they reflect the application's functionality only, not who is executing the the functionality).
