Google App 引擎的 JSF 有 Google App 工具 JSF 。 不知道如何调用有管理贝的调用方法
原标题:JSF with google app engine. not sure how to call method in managedbean

我正与 JSF 使用 Google 应用程序引擎。 当用户按下此按钮时, 我想调用一个函数 :

<p:commandButton value="Ajax Submit" action="#{todo.test}" /> 

我将待办事宜置于 src-> package 测试 123 之下。

package test123;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.event.ActionEvent;


@ManagedBean(name="todo")
@SessionScoped
public class Todo {  

    public void test(ActionEvent event){ 
  System.out.println("lol");    
    }
}  

but when i press button, error occurs: sth like this:

 javax.el.MethodNotFoundException: /Template/default.xhtml @39,38 action="#{todo.test}": Method not found: [email protected]()

我错了吗 还是我需要做一些配置

谢谢 谢谢

最佳回答

使用 actionListener="\\\\ todo. test}" 或尝试 :

public void test()
{ 
  System.out.println("lol");    
}
