使用哨兵模式连接redis连接池时，遇到错误：

Caused by: redis.clients.jedis.exceptions.JedisDataException:

 ERR Client sent AUTH, but no password is set

发现是redis没有设置密码，程序却发送了auth选项。

工程里JedisSentinelPool是通过spring配置的：

    <bean id="jedisPool" class="redis.clients.jedis.JedisSentinelPool" destroy-method="destroy">        <constructor-arg value="${redis.master}" />        <constructor-arg>            <set>                <value>${redis.host}:${redis.port}</value>            </set>        </constructor-arg>        <constructor-arg ref="jedisPoolConfig" />        <constructor-arg value="${redis.timeout}"/>    </bean>

发现JedisSentinelPool的构造方法有2个类似的：

public JedisSentinelPool(String masterName, Set sentinels,GenericObjectPoolConfig poolConfig, int timeout) {this(masterName, sentinels, poolConfig, timeout, null, 0);}public JedisSentinelPool(String masterName, Set sentinels,GenericObjectPoolConfig poolConfig, String password) {this(masterName, sentinels, poolConfig, 2000, password);}

JedisSentinelPool初始化构造方法的入参是根据spring配置文件的参数配置顺序加载的，JedisSentinelPool使用了第二个构造方法，导致上面的错误。

解决方法，给配置文件的参数配置name属性.

    <bean id="jedisPool" class="redis.clients.jedis.JedisSentinelPool" destroy-method="destroy">        <constructor-arg name="masterName" value="${redis.master}" />        <constructor-arg name="sentinels">            <set>                <value>${redis.host}:${redis.port}</value>            </set>        </constructor-arg>        <constructor-arg name="poolConfig" ref="jedisPoolConfig" />        <constructor-arg  name="timeout" value="${redis.timeout}"/>    </bean>

问题解决
