1、产生原因：客户端去redis服务器拿连接（代码描述的是租用对象borrowObject）的时候，池中无可用连接，即池中所有连接被占用，且在等待时候设定的超时时间后还没拿到时，报出此异常。

2、解决办法：调整JedisPoolConfig中maxActive为适合自己系统的阀值。

<bean id="dataJedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <property name="maxActive" value="300"/>
       <property name="maxIdle" value="100"/>
        <property name="maxWait" value="10000"/>
        <property name="testOnBorrow" value="true"/>
</bean>
