java session共享服务器 java redis session共享

1. pom添加依赖

<dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session-data-redis</artifactId>
  <version>1.2.1.RELEASE</version>
</dependency>
<dependency>
  <groupId>redis.clients</groupId>
  <artifactId>jedis</artifactId>
  <version>2.8.1</version>
</dependency>

2. spring-redis.xml

<context:property-placeholder location="classpath:redis.properties"  ignore-unresolvable="true" />
    
    <!-- session设置 -->
    <bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
        <property name="maxInactiveIntervalInSeconds" value="3600"></property>
    </bean>
    <!-- redis连接池 -->
    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"/>

    <!-- redis连接工厂 -->
    <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="hostName" value="${redis.hostName}"/>
        <property name="port" value="${redis.port}"/>
        <property name="database" value="${redis.database}"></property>
        <property name="password" value="${redis.password}"/>
        <property name="timeout" value="${redis.timeout}"/>
        <property name="poolConfig" ref="poolConfig"></property>
    </bean>

3. redis.properties

redis.hostName=
redis.port=6379
redis.password=
redis.database=5
redis.timeout=200000

4.web.xml添加拦截器

<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>

5.在controller里面操作session就会存到redis

//存入session、redis
request.getSession().setAttribute("userLogin", user);



//先会去redis找，然后session中找。
request.getSession.getAttribute("userLogin")；
