推荐答案

您所指的是 Spring 上下文生命周期的侦听器.那不是你想要的.

What you are referring to are listeners for Spring context life-cycle. That is not what you want.

Spring 启动文档说明:

使用嵌入式 servlet 容器时，您可以注册 Servlet，过滤器和 Servlet 规范中的所有侦听器(例如HttpSessionListener) 直接作为 Spring bean.这可以是如果您想引用您的值，则特别方便配置期间的 application.properties.

When using an embedded servlet container you can register Servlets, Filters and all the listeners from the Servlet spec (e.g. HttpSessionListener) directly as Spring beans. This can be particularly convenient if you want to refer to a value from your application.properties during configuration.

更新:

import org.springframework.context.annotation.Bean;
import javax.servlet.http.HttpSessionListener;

@Bean
public HttpSessionListener httpSessionListener(){
    // MySessionListener should implement javax.servlet.http.HttpSessionListener
    return new MySessionListener(); 
}
