Question

我有一个使用spring和spring boot的项目。它具有一些自定义安全机制以及侦听会话创建和会话破坏事件：

@WebListener
public class MySessionListener implements HttpSessionListener {
    @Override
    public void sessionCreated(HttpSessionEvent httpSessionEvent) {
        System.out.println("==== Session is created ====");

        //sets a custom session timeout
        httpSessionEvent.getSession().setMaxInactiveInterval(10);
    }

    @Override
    public void sessionDestroyed(HttpSessionEvent httpSessionEvent) {
        System.out.println("==== Session is destroyed ====");
    }
}

通过以下方式实例化：

导入org.springframework.boot.web.servlet.ServletContextInitializer; 导入org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; 导入sample.session.MySessionListener;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;

public class WebAppInitializer implements ServletContextInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        //only https allowed
        //servletContext.getSessionCookieConfig().setSecure(true);

        //add session listener for example to influence session-timeout
        servletContext.addListener(new MySessionListener());
    }
}

具有：

@SpringBootApplication
public class SpringSecApp {
    public static void main(String[] args) {
        SpringApplication.run(new Class[] { SpringSecApp.class, WebAppInitializer.class }, args);
    }
}

现在，我添加了一些配置以使Spring将会话信息写入MySql DB。为此，我必须将pom.xml从Spring-Boot 1.5.x更新到2.1.3。

现在，此会话信息编写工作正常，但我认识到不再处理会话事件；我想原因在于依赖关系，因为我没有更改我上面发布的有关会话侦听的相关代码段，但找不到它。我将不胜感激！我将包括2个pom版本；首先是当前提交，然后是最后提交的提交，在该提交中，我可以确认会话事件处理可以正常工作。当前版本：

编辑：我尝试了MyTwoCents方法，该方法没有任何改变；而且，似乎 onStartup -方法根本没有执行（从该方法到标准输出的打印都不会显示）。

EDIT2：我可以确认正在调用ServletContextInitializer的 onStartup -Method，但是 MySessionListener 的 sessionCreated 和 sessionDestroyed 根本没有被调用。

Answer 1

也许您需要这样做

@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        servletContext.addListener(new MySessionListener());

        super.onStartup(servletContext);
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }

}

还有一个注释from Doc

用于以编程方式配置Servlet 3.0+上下文的接口。与WebApplicationInitializer不同，实现此目的的类接口（并且不实现WebApplicationInitializer）将不会由SpringServletContainerInitializer检测到，因此不会被检测到自动由Servlet容器引导。

Answer 2

我不确定这是否可以正确处理此问题，但事实证明，这个问题本身是不合适的，因为根本原因没有切换从启动1到启动2，而是我切换的原因，那就是使用 JDBC会话存储库。

在这种情况下，我们可以参考：

https://docs.spring.io/spring-session/docs/current/reference/html5/#api-jdbcoperationssessionrepository

告诉我们：

请注意，此实现不支持发布会话事件。

因此，该问题并不完全适合该问题，但我想将其发布给可能来自相似方向的人，即使这不是可接受的答案。这也意味着将标题更改为“如何解决...” 宁愿绘制一个很难追溯的后历史记录，我想避免。我将提出一个更适当的问题。

Answer 3

请查看是否可行

public class SessionExpirationListener implements ApplicationListener<SessionDestroyedEvent> {

    @Override
    public void onApplicationEvent(SessionDestroyedEvent event) {
//your code
    }
}

更新到SpringBoot2后，监听会话事件不起作用
