redis.clients.jedis.exceptions.JedisDataException: ERR Client sent AUTH, but no password is set

使用哨兵模式連接redis連接池時，遇到錯誤：

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

 ERR Client sent AUTH, but no password is set

發現是redis沒有設置密碼，程序卻發送了auth選項。

工程里JedisSentinelPool是通過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>

發現JedisSentinelPool的構造方法有2個類似的：

	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初始化構造方法的入參是根據spring配置文件的參數配置順序加載的，JedisSentinelPool使用了第二個構造方法，導致上面的錯誤。

解決方法，給配置文件的參數配置name屬性.

    <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>
