单机版配置

 <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <!-- 最大连接数 -->
        <property name="maxTotal" value="100" />
        <!-- 最大空闲连接数 -->
        <property name="maxIdle" value="300" />
        <!-- 每次释放连接的最大数目 -->
        <property name="numTestsPerEvictionRun" value="1024" />
        <!-- 释放连接的扫描间隔（毫秒） -->
        <property name="timeBetweenEvictionRunsMillis" value="30000" />
        <!-- 连接最小空闲时间 -->
        <property name="minEvictableIdleTimeMillis" value="1800000" />
        <!-- 连接空闲多久后释放, 当空闲时间>该值 且 空闲连接>最大空闲连接数 时直接释放 -->
        <property name="softMinEvictableIdleTimeMillis" value="10000" />
        <!-- 获取连接时的最大等待毫秒数,小于零:阻塞不确定的时间,默认-1 -->
        <property name="maxWaitMillis" value="1500" />
        <!-- 在获取连接的时候检查有效性, 默认false -->
        <property name="testOnBorrow" value="true" />
        <!-- 在空闲时检查有效性, 默认false -->
        <property name="testWhileIdle" value="true" />
        <!-- 连接耗尽时是否阻塞, false报异常,ture阻塞直到超时, 默认true -->
        <property name="blockWhenExhausted" value="false" />
    </bean> 
     <bean id="redisClient" class="redis.clients.jedis.JedisPool">
        <constructor-arg name="poolConfig" ref="jedisPoolConfig"></constructor-arg>
        <constructor-arg name="host" value="${redis.host}"></constructor-arg>
        <constructor-arg name="port" value="${redis.port}"></constructor-arg>

        <!-- <constructor-arg name="timeout" value="${redis.timeOut}"></constructor-arg>

    </bean>

集群版配置,其中constructor-arg name="host" value="192.168.199.203"指定ip更换即可

<bean id="redisClient" class="redis.clients.jedis.JedisCluster">
        <constructor-arg name="nodes">
