如何从ApplicationListener方法获取会话对象 [英] How I can get session object from ApplicationListener method

问题描述

我想在用户身份验证成功后将对象添加到HttpSession.请不要使用SavedRequestAwareAuthenticationSuccessHandler建议解决方案，因为在此应用中，由于某种原因，应用会忽略原始请求.

I want to add object to HttpSession after successful user authentication. Please don't suggest solution with SavedRequestAwareAuthenticationSuccessHandler because in this app for some reason application are ingnoring original request.

public class AuthenticationSuccessListener implements ApplicationListener<InteractiveAuthenticationSuccessEvent> {
    @Override
    public void onApplicationEvent(InteractiveAuthenticationSuccessEvent e) {
        //adding object to HttpSession
    }
} 

推荐答案

据我所知，ApplicationListener实例只是ApplicationContext中的bean.因此，您应该能够向其中注入其他bean或资源.

As far as I am aware, ApplicationListener instances are just beans within your ApplicationContext. Therefore you should be able to inject other beans or resources into them.

因此要获得对当前HttpSession实例的引用:

So to get a reference to the current HttpSession instance:

public class AuthenticationSuccessListener implements ApplicationListener<InteractiveAuthenticationSuccessEvent> {

@Autowired
private HttpSession httpSession;

        @Override
        public void onApplicationEvent(InteractiveAuthenticationSuccessEvent e) {
               //adding object to HttpSession
        }
}

Spring将使用其HttpSession -other-injection"rel =" noreferrer>作用域代理机制，确保您获得与当前执行线程相关的HTTPSession.

Spring will inject the HttpSession using its scoped proxy mechanism ensuring that you get the HTTPSession relevant to the current thread of execution.

您还需要确保在web.xml中注册一个RequestContextListener，以便Spring可以注入当前的HTTPSession.

You'll also need to ensure that you register a RequestContextListener in your web.xml so that Spring can inject the current HTTPSession.

<listener>  
   <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>  
</listener>
