用了jodis，配置JedisPoolConfig后总是超时。原来用的jedis，JedisPoolConfig的配置没有变，用jedis不超时。

tydldd commented 8 years ago

config.setMaxTotal(50); // 最大空闲连接数, 默认8个 config.setMaxIdle(getPropertyInt(props, "redis.maxIdle")); // 默认-1 config.setMaxWaitMillis(10000); // 逐出连接的最小空闲时间默认1800000毫秒(30分钟), 设置成3分钟 config.setMinEvictableIdleTimeMillis(180000);

        // 在获取连接的时候检查有效性, 默认false
        config.setTestOnBorrow(false);
        // 在空闲时检查有效性, 默认false
        config.setTestWhileIdle(true);
        // 逐出扫描的时间间隔(毫秒) 如果为负数,则不运行逐出线程, 默认-1，设置2分钟
        config.setTimeBetweenEvictionRunsMillis(10000);

服务在云上，每4分钟被切断一次长连接。现在的问题似乎是空闲检查的心跳没起作用

超时的异常发一下？

Caused by: java.util.NoSuchElementException: Timeout waiting for idle object 这个说明是从pool获取对象超时了。和网络连接没有关系。是不是你从pool拿对象后用完了没close？

tydldd commented 8 years ago

jodis没有关闭api吧

yangzhe1991 commented 8 years ago

jodis底层就是jedis，api是一样的。getResource拿到的Jedis对象用完了要执行close，和直接用JedisPool的用法是一样的

tydldd commented 8 years ago

原来用JedisPool确实是有pool.returnResourceObject(redis);，用jodis没发现相似的方法

yangzhe1991 commented 8 years ago

returnResourceObject是旧版jedis的用法，新版jedis一律使用Jedis.close

好。我试试
