wicket 框架中请求对象的会话处理

session handling for request object in wicket framework(wicket 框架中请求对象的会话处理)

问题描述

1) 我在下面给出的请求对象中添加了一个元素，我需要在我的网页中获取/读取它，我该怎么做?

1) i have added an element in request object given below, i need to get/read this in my webpage, how can i do it?

<input type="hidden"> wicket:id="submitted" value="false" />

例如:在 servlet 中，使用隐藏会话中的 request.getParameter("submitted").

eg: in servlet, use request.getParameter("submitted") from hidden session.

2) 在我的控制器类中，我想在会话或隐藏字段中设置值，以便我可以识别用户是否已经处理了请求或进入了我的代码块.

2) in my controller class i want to set the value in session or hidden field, so that i can identify the user if he already processed the request or enetered my block of code.

推荐答案

1) 使用HiddenField

2) 使用自定义 WebSession 对象:

2) use a custom WebSession object:

public class MySession extends WebSession{
    public Mysession(Request request){super(request);}
    private boolean completedRegistration;

    public boolean hasCompletedRegistration() {
        return completedRegistration;
    }

    public void setCompletedRegistration(boolean completedRegistration) {
        this.completedRegistration = completedRegistration;
    }
}
