标签： spring spring-mvc

您好我是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的注释，我在会话时遇到麻烦。 我struts2我使用会话感知，它存储地图vales。在春天我怎么能实现任何人都可以帮助我。 ... 如果任何一个回复...在一周内它对我更有帮助。 这是我的struts 2.x动作类。

    {

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

答案 0 :(得分：0)

我在我的控制器上使用SessionAttributes注释，让会话弹簧保留一些我将放入模型中的属性。 Spring将这些属性透明地放入和检索这些属性，因为它们被放入模型或注入控制器方法。正如javadoc所指出的，当临时在会话中设置属性时，这是一种很好的方法，并且它建议另一种方法来直接访问应该永久存储的属性的会话。描述了此方法的详细信息here。

你应该为此而努力。

或者，例如，对于安全性数据，您可以在类型为java.util.HashMap的应用程序上下文中创建一个会话范围的bean，然后将其注入控制器。我不知道这是不是一个好习惯，但优点是你可以根据需要在服务中注入这个bean。
