session+spring+redis實現分佈式session共享，實測通過

  一、引入maven依賴，項目spring是4.1.5，需要兼容，否則報錯，

  <spring.version>4.1.5.RELEASE</spring.version>

<!-- 使用redis存儲session -->
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
    <version>1.1.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session</artifactId>
    <version>1.1.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>1.7.2.RELEASE</version>
    <!-- <version>1.6.6.RELEASE</version> --><!-- 1.7以下不支持集羣 -->
</dependency>
		
<dependency>
    <groupId>commons-pool</groupId>
    <artifactId>commons-pool</artifactId>
    <version>1.2</version>
    <exclusions>
    	<exclusion>  
              <groupId>xerces</groupId>  
      	      <artifactId>xerces</artifactId>  
       	</exclusion>  
       	<exclusion>
       	      <groupId>xml-apis</groupId>
     	      <artifactId>xml-apis</artifactId>
     	</exclusion>
     </exclusions>
</dependency>

 

 

二、web.xml增加過濾器，放在最前面

<!-- session -->
<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>

 

三、配置spring-session.xml：

單機版redis：

<?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"
    xmlns:tx="http://www.springframework.org/schema/tx"
    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"/><!-- 最大空閒連接數, 默認8個 -->
        <property name="maxTotal" value="20"/><!-- 最大連接數, 默認8個 -->
        <property name="blockWhenExhausted" value="true"/><!-- 連接耗盡時是否阻塞, false報異常,ture阻塞直到超時, 默認true -->
        <property name="maxWaitMillis" value="1000"/><!-- 獲取連接時的最大等待毫秒數(如果設置爲阻塞時BlockWhenExhausted),如果超時就拋異常, 小於零:阻塞不確定的時間,  默認-1 -->
        <property name="testOnBorrow" value="true"/><!-- 在獲取連接的時候檢查有效性, 默認false -->
    </bean>
   
    <!-- redis連接配置，依次爲主機ip，端口，密碼，是否使用池，連接池配置引用 -->
    <bean id="connectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
        p:host-name="127.0.0.1" p:port="6379" p:usePool="true" p:pool-config-ref="jedisPoolConfig">
    </bean>
   
    <!-- 配置spring-session -->
    <bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
        <!-- session過期時間,單位是秒 -->
        <property name="maxInactiveIntervalInSeconds" value="30"></property>
    </bean>
</beans>

集羣：

<?xml version="1.0" encoding="UTF-8"?>
<beans
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        http://www.springframework.org/schema/beans/spring-beans.xsd">
   
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">

        <property name="blockWhenExhausted" value="true"/><!-- 連接耗盡時是否阻塞, false報異常,ture阻塞直到超時, 默認true -->
        <property name="maxWaitMillis" value="1000"/><!-- 獲取連接時的最大等待毫秒數(如果設置爲阻塞時BlockWhenExhausted),如果超時就拋異常, 小於零:阻塞不確定的時間,  默認-1 -->
