Java Spring 3.5 如何将 HttpSessionEventPublisher 添加到我的启动配置中

Spring 3.5 how to add HttpSessionEventPublisher to my boot configuration

提问by Alexandr

I want to listen to session life cycle events. I read about adding

我想收听会话生命周期事件。我读过关于添加

<listener>
   <listener-class>
     org.springframework.security.web.session.HttpSessionEventPublisher
   </listener-class>
</listener>

to web.xml. But I don't have it. I am using class that extends SpringBootServletInitializer. How I can add this listener?

到 web.xml。但我没有。我正在使用扩展 SpringBootServletInitializer 的类。如何添加此侦听器？

Adding Listener in Class which is extending SpringBootSelvletInitializer can be done as below.

在扩展 SpringBootSelvletInitializer 的类中添加监听器可以如下完成。

    @Configuration
    public class Application extends SpringBootServletInitializer {

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    SpringApplicationBuilder app=application.sources(Application.class, ComponentConfiguration.class);
    app.listeners(bootstrapContext.commandLineListener());
    return app;
}

As the builder class is having listener method which use to add all the listener which is given to be registered. Github link for SpringApplicationBuilder is http://goo.gl/EGj6jE

由于构建器类具有用于添加所有要注册的侦听器的侦听器方法。SpringApplicationBuilder 的 Github 链接是http://goo.gl/EGj6jE

I think this will solve your issue.

我认为这将解决您的问题。

You can use ServletListenerRegistrationBean:

您可以使用ServletListenerRegistrationBean：

@Bean
public ServletListenerRegistrationBean<HttpSessionEventPublisher> httpSessionEventPublisher() {
    return new ServletListenerRegistrationBean<HttpSessionEventPublisher>(new HttpSessionEventPublisher());
}

From SpringBootServletInitializerjavadoc : A handy opinionated WebApplicationInitializer for applications that only have one Spring servlet, and no more than a single filter (which itself is only enabled when Spring Security is detected). If your application is more complicated consider using one of the other WebApplicationInitializers

来自SpringBootServletInitializerjavadoc ：一个方便的、自以为是的 WebApplicationInitializer，适用于只有一个 Spring servlet 且不超过一个过滤器（它本身仅在检测到 Spring Security 时才启用）的应用程序。如果您的应用程序更复杂，请考虑使用其他 WebApplicationInitializers 之一

So if you want to generate a war and you want to include a session listener, you should use directly a WebApplicationInitializer. Here is an example from the javadoc :

因此，如果您想生成War并希望包含会话侦听器，则应直接使用WebApplicationInitializer. 这是 javadoc 中的一个示例：

public class MyWebAppInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext container) {
      // Create the 'root' Spring application context
      AnnotationConfigWebApplicationContext rootContext =
        new AnnotationConfigWebApplicationContext();
      rootContext.register(AppConfig.class);

      // Manage the lifecycle of the root application context
      container.addListener(new ContextLoaderListener(rootContext));

      // Create the dispatcher servlet's Spring application context
      AnnotationConfigWebApplicationContext dispatcherContext =
        new AnnotationConfigWebApplicationContext();
      dispatcherContext.register(DispatcherConfig.class);

      // Register and map the dispatcher servlet
      ServletRegistration.Dynamic dispatcher =
        container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
      dispatcher.setLoadOnStartup(1);
      dispatcher.addMapping("/");
    }

}

As you have full control on the ServletContext before it is fully initialized, it is easy to add your listener :

由于您在完全初始化之前对 ServletContext 拥有完全控制权，因此很容易添加您的侦听器：

    container.addListener(YourListener.class);

Just to provide reference to official documentation, http://docs.spring.io/spring-session/docs/current-SNAPSHOT/reference/html5/#httpsession-rest

仅供参考官方文档， http://docs.spring.io/spring-session/docs/current-SNAPSHOT/reference/html5/#httpsession-rest

Here if you refer to, HttpSessionListenertopic, you will find the clear example of doing it both Javaand XMLconfiguration way.

在这里，如果您参考HttpSessionListener主题，您将找到同时执行此操作Java和XML配置方式的清晰示例。

if your configuration support Redis

如果您的配置支持 Redis

@Configuration
@EnableRedisHttpSession
public class RedisHttpSessionConfig {

    @Bean
    public HttpSessionEventPublisher httpSessionEventPublisher() {
            return new HttpSessionEventPublisher();
    }

    // ...
}

In XML configuration, this might look like

在 XML 配置中，这可能看起来像

<bean class="org.springframework.security.web.session.HttpSessionEventPublisher"/>
