最近研究session共享，接触spring-session，特此记录！

1、所需jar包

spring-session-1.3.0.RELEASE.jar

spring-session-data-redis-1.3.0.RELEASE.jar

spring-data-redis-1.7.1.RELEASE.jar

2、配置文件

spring-session.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    
        <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
            <property name="maxIdle" value="10"/>
            <property name="maxTotal" value="20"/>
            <property name="blockWhenExhausted" value="true"/>
            <property name="maxWaitMillis" value="1000"/>
            <property name="testOnBorrow" value="true"/>
        </bean>
    
        
        <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
              p:host-name="xxxxxxx"
              p:port="26379"
              p:password=""
              p:usePool="true"
              p:pool-config-ref="jedisPoolConfig">
        </bean>
    
        
        <bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
            
            <property name="maxInactiveIntervalInSeconds" value="30"></property>
        </bean>
    </beans>

applicatonContext.xml

web.xml

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"

        <url-pattern>/</url-pattern>
      </servlet-mapping>
        
    </web-app>

3、后台测试代码

package com.hnac.hzinfo.zyj;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpSession;
    import java.util.HashMap;
    import java.util.Map;
    
    @Controller
    public class SessionTest {
    
        @RequestMapping("/setUrl")
        @ResponseBody
        public Map<String,Object> setUrl(HttpServletRequest request){
            request.getSession().setAttribute("url", request.getRequestURL());
            Map<String,Object> map = new HashMap<>();
            map.put("url", request.getRequestURL());
            return map;
        }
    
        @RequestMapping("/getSession")
        @ResponseBody
        public Map<String,Object> getSession(HttpServletRequest request){
            Map<String,Object> map = new HashMap<>();
            map.put("sessionId", request.getSession().getId());
            map.put("url", request.getSession().getAttribute("url"));
            return map;
        }
    
    }

session可在RedisDesktopManager查看。
