与多个处理程序的码头会议

Question

I have two handlers need to share information with session. However I have no idea about doing this in Jetty.

I know how to set different session for different handler, and I tried to wrap them together like:

    ContextHandler loginContext = new ContextHandler("/login");
    ContextHandler reqContext = new ContextHandler("/req");

    ContextHandlerCollection contexts = new ContextHandlerCollection();
    contexts.setHandlers(new Handler[] { loginContext, reqContext });

    HashSessionManager manager = new HashSessionManager();
    SessionHandler session = new SessionHandler(manager);
    loginContext.setHandler(login);
    reqContext.setHandler(req);

    session.setHandler(contexts);
    server.setHandler(session);

This leads up to a java.lang.NullPointerException.

Can anyone help me with this?

我面临着同样的要求，我发现sessionid（cookie中的JSESSIONID）发生了变化。因此，我认为更改后的sessionid无法在第一个会话中获取。当我们获得session时，sessionmanager将创建新的session。 -域会犯此错误。
