jedis pool的问题

在使用jedis pool时遇到了这个问题：It seems like server has closed the connection

原因分析：

1.redis server 关闭了此客户端的连接:server端设置了maxidletime(默认是5分钟），服务端会不断循环检测clinet的最后一次通信时间（lastinteraction），如果大于maxidletime，则关闭连接，并回收相关资源。client在向该连接中写数据后就会由于server端已经关闭而出现 broken pipe的问题。

2.pool的设置错误:

上面的这种配法在spring初始化时获取一次实例化jedisCommands，而后每次的redis的调用时并未从pool中获取

解决方案：

设置

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
            <property name="maxActive"  value="20" />
            <property name="maxIdle" value="10" />
            <property name="maxWait" value="1000" />
            <property name="testOnBorrow"  value="true"/>
        </bean>
    
        
        <bean id="jedis.shardInfo" class="redis.clients.jedis.JedisShardInfo">
            <constructor-arg index="0" value="*.*.*.*" />
            <constructor-arg index="1" value="6379" />
        </bean>
    
        
        <bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool">
            <constructor-arg index="0" ref="jedisPoolConfig" />
            <constructor-arg index="1">
                <list>
                    <ref bean="jedis.shardInfo" />
                </list>
            </constructor-arg>
        </bean>
