如果你关注Spring Session JDBC的实现可关注前面一篇文章。本文所谓的Spring Session Redis的简单入门，主要是根据github上的Spring Session项目源码实践而来，具体是从该项目中摘一些示例代码，按照需要，修改而来。

本文目标

实现基于Redis的Spring Session管理（不含Redis的搭建过程），spring-session-data-redis的版本为2.1.3.RELEASE，依赖的Spring版本为5.1.4.RELEASE，实现一个分布式的Session管理示例，多个服务器（端口不同）下session数据一致。

最佳实践

1.Maven依赖

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.11</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>org.springframework.session</groupId>
    <artifactId>spring-session-data-redis</artifactId>
    <version>2.1.3.RELEASE</version>
</dependency>
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.1</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>5.1.4.RELEASE</version>
</dependency>

</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.1.7</version>
</dependency>

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.58</version>
</dependency>

2.session.xml参数配置

<context:annotation-config/>
<bean class="org.springframework.session.data.redis.config.annotation.web.http.RedisHttpSessionConfiguration">
</bean>
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <array>
            <value>classpath:spring-config-redis.properties</value>
        </array>
    </property>
</bean>

<bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory"
      p:hostName="${spring.redis.hostName}" p:port="${spring.redis.port}" p:database="${spring.redis.database}"
      p:poolConfig-ref="jedisPoolConfig"
>
</bean>
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
    <property name="maxTotal" value="${spring.redis.maxTotal}"/>
    <property name="maxIdle" value="${spring.redis.maxIdle}"/>
    <property name="minIdle" value="${spring.redis.minIdle}"/>
    <property name="testOnBorrow" value="${spring.redis.testOnBorrow}"/>
    <property name="maxWaitMillis" value="${spring.redis.maxWaitMillis}"/>
</bean>
