springboot设置session超时和session监听

 

                             2.0版本以下设置session超时时间

1.  springboot 2.0版本以下配置session超时

     1.1 application.properties配置文件： spring.session.store-type=none

     1.2 引入 spring-boot和spring-session 2个依赖包

---

<!--session管理-->

<dependency>

<groupId>org.springframework.session</groupId>

<artifactId>spring-session</artifactId>

<version>1.3.2.RELEASE</version>

</dependency>

<!--引入配置-->

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot</artifactId>

<version>1.5.4.RELEASE</version>

</dependency>

     1.3在springboot启动类注入以下bean对象

package com.sinosoft.session;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;

import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;

import org.springframework.context.annotation.Bean;

import java.util.concurrent.TimeUnit;

@SpringBootApplication

public class SessionApplication {

public static void main(String[] args) {

SpringApplication.run(SessionApplication.class, args

);

}

@Bean

public EmbeddedServletContainerCustomizer embeddedServletContainerCustomizer() {

return new EmbeddedServletContainerCustomizer() {

@Override

public void customize(ConfigurableEmbeddedServletContainer container) {

//设置session超时时间为1分钟

container.setSessionTimeout(1, TimeUnit.MINUTES);

}

};

}

}

2.添加session管理器和监听器

package com.sinosoft.session.server;

import java.util.HashMap;

import javax.servlet.http.HttpSession;

/**

* Created by lijunming

* on date 2018-09-20

* session管理器

* time 20:01

*/

public class MySessionContext {

private static HashMap mymap = new HashMap();

public static synchronized void AddSession(HttpSession session) {

if (session != null) {

mymap.put(session.getId(), session);

}

}

public static synchronized void DelSession(HttpSession session) {

if (session != null) {

mymap.remove(session.getId());

}

}

public static synchronized HttpSession getSession(String session_id) {

if (session_id == null)

return null;

return (HttpSession) mymap.get(session_id);

}

}

package com.sinosoft.session.server;

import org.springframework.stereotype.Component;

import javax.servlet.http.HttpSession;

import javax.servlet.http.HttpSessionEvent;

import javax.servlet.http.HttpSessionListener;

/**

* Created by lijunming

* on date 2018-09-20

* session监听器

* time 20:02

*/

@Component

public class MySessionListener implements HttpSessionListener {

@Override

public void sessionCreated(HttpSessionEvent httpSessionEvent) {

System.out.println("session正在創建");

MySessionContext.AddSession(httpSessionEvent.getSession());

}

@Override

public void sessionDestroyed(HttpSessionEvent httpSessionEvent) {

HttpSession session = httpSessionEvent.getSession();

System.out.println("session注銷中");

MySessionContext.DelSession(session);

}

}
