在spring MVC項目中集成Spring session redis （使用spring session框架，redis做爲存儲緩存）

1.爲項目增長以來  pom.xml中使用

<!-- spring session 單點登陸 -->
//本項目使用spring4.0.3
<dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session-data-redis</artifactId>
  <version>1.2.0.RELEASE</version>
</dependency>

2.配置spring session redis 的注入

採用新建配置文件方式，文件名：

applicationContext-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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

//bean的屬性能夠本身進入類中查看，而後根據須要設置
    <bean id="redisHttpSessionConfiguration" class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
        <property name="maxInactiveIntervalInSeconds" value="1800" />
    </bean>
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="20"/>
    </bean>
//配置redis鏈接IP PORT 若是有密碼須要配置密碼，spring session redis 是單實例的，不支持分佈式
    <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">
        <property name="hostName" value="127.0.0.1" />
        <property name="port" value="6379" />
        <property name="poolConfig" ref="jedisPoolConfig" />
    </bean>
</beans>

配置完記得將配置引入到

applicationContext.xml中

<import resource="applicationContext-spring-session.xml"/>

3.在web.xml中配置filter

<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>*.do</url-pattern>
</filter-mapping>
