嗨，我是 Spring MVC 注释的新手。我现在正在分配将 Stuts 2.x 控制器部分移动到基于 Spring 注释的任务，我在会话时遇到了麻烦。我使用了 struts2，我使用了 session 感知，它存储了 map vales。在春天，我该如何实现任何人都可以帮助我。...如果有人在一周内回复...对我更有帮助。这是我的 struts 2.x 动作类。

这是我的 CMTAction 课程

    package com.cmt.admin.web.action;

import java.util.Map;

import com.cmt.admin.dao.User;
import com.cmt.common.constants.CommonConstants;
import com.opensymphony.xwork2.ActionSupport;

public class CMTAction extends ActionSupport implements SessionAware
{

    // This Map will contain vales in Session
    private Map<String, Object> sessionMap;

    protected User getLoggedInUser()
    {

        User user = (User) this.getSession().get(CommonConstants.LOGGED_INUSER);
        return user;
    }

    protected void showActionMessage(String message)
    {
        addActionMessage(message);
    }

    protected void showErrorMessage(String message)
    {
        addActionError(message);
    }

    @Override
    public void setSession(Map<String, Object> session)
    {
        this.sessionMap = session;
    }

    public Map<String, Object> getSession()
    {
        return sessionMap;
    }


}

我在我的控制器上使用SessionAttributes注释让 spring 在会话中保留一些我将放在我的模型中的属性。当它们被放入模型或注入控制器方法时，Spring 透明地从会话中放置和检索这些属性。正如 javadoc 所指出的，当属性要在会话中临时设置时，这是一个好方法，它建议另一种方法直接访问会话以获取应该永久存储的属性。此方法在此处进行了足够详细的描述。

您可能应该这样做。

或者，例如，对于您的安全数据，您可以在 java.util.HashMap 类型的应用程序上下文中创建一个会话范围的 bean，然后将其注入到您的控制器中。我不知道这是否是一个好习惯，但优点是您可以在需要时将此 bean 注入服务中。
