execludeMethods不起作用

Question

这是自定义的拦截器

public class IsLoginInterceptor extends MethodFilterInterceptor{

@Override
protected String doIntercept(ActionInvocation invocation) throws Exception {
Map session=invocation.getInvocationContext().getSession();
Leaguer lea=(Leaguer)session.get("lea");
if(lea==null){
return Action.LOGIN;
}
return invocation.invoke();
}

}
这是strust配置

/jsp2/login.jsp

regist,login,passwordReset

求大神解决一下
