SpringSession

一、集群下session丢失原理及解决

 

二、使用springSession

1、添加依赖

    <dependency>
      <groupId>org.springframework.session</groupId>
      <artifactId>spring-session-data-redis</artifactId>
      <version>1.3.5.RELEASE</version>
    </dependency>


    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>
      <version>5.2.5.RELEASE</version>
    </dependency>

 

2、添加过滤器

    <filter>
        <filter-name>springSessionRepositoryFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>springSessionRepositoryFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

 

3、添加bean对象

　　
//专门用于配置springsession
<bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration"></bean>


//配置redis
    <bean id="jedisConnectFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">

        <property name="hostName" value="192.168.31.49" />
        <property name="port" value="6379" />
        <property name="password" value="q123456" />

    </bean>

//启动spring注解支持
    <context:annotation-config />

 

三、配置springsession

1、上下文根不同时

 

 

2、子域名不同时
