关于Session的问题网上有各个方面的针对，有在nginx 上处理： ip_hash的session，有在 tomcat 做处理：修改Context文件，有针对项目做处理。本篇就是对项目处理

1、首先我的项目是用Maven（如果没有用maven可以去下载），使用到的jar包有下：

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-webmvc</artifactId>
  <version>${spring.version}</version>
</dependency>


<dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session</artifactId>
  <version>1.3.1.RELEASE</version>
</dependency>

<dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session-data-redis</artifactId>
  <version>1.3.1.RELEASE</version>
</dependency>


<dependency>
  <groupId>redis.clients</groupId>
  <artifactId>jedis</artifactId>
  <version>2.9.0</version>
  <type>jar</type>
  <scope>compile</scope>
</dependency>


<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-pool2</artifactId>
  <version>2.4.2</version>
</dependency>

<!-- 日志文件管理包 -->
<!-- log start -->
<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>${log4j.version}</version>
</dependency>
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>${slf4j.version}</version>
</dependency>
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>${slf4j.version}</version>
</dependency>
<!-- log end -->

2、配置spring 配置文件 applicationContext-redis.xml

　　<context:annotation-config />

    <context:property-placeholder location="classpath:redis.properties"/>

    <bean id="redisHttpSessionConfiguration"
          class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
        <property name="maxInactiveIntervalInSeconds" value="3600"/>
    </bean>

    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxTotal" value="100" />
        <property name="maxIdle" value="10" />
    </bean>

    <bean id="jedisConnectionFactory"
          class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" destroy-method="destroy">
        <property name="hostName" value="${redis.host}"/>
        <property name="port" value="${redis.port}"/>
        <property name="password" value="${redis.pass}" />
        <property name="timeout" value="3000"/>
        <property name="usePool" value="true"/>
        <property name="poolConfig" ref="jedisPoolConfig"/>
    </bean>

3、web.xml 加入

<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>

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext*.xml</param-value>
  </context-param>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
