配置 Jedis 超时 [英] Configure Jedis timeout

问题描述

我在完成 .hgetall() 时遇到问题，这是我尝试过的:

I'm having problems completing an .hgetall(), here's what I've tried:

Jedis jedis = new Jedis(REDIS_MASTER_NODE);
jedis.connect();
jedis.configSet("timeout", "30");

Map<String, String> alreadyStored = jedis.hgetAll(redisTargetHash);

这是我得到的:

Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: java.net.SocketTimeoutException: Read timed out
    at redis.clients.jedis.Protocol.process(Protocol.java:79)
    at redis.clients.jedis.Protocol.read(Protocol.java:131)
    at redis.clients.jedis.Connection.getBinaryMultiBulkReply(Connection.java:199)
    at redis.clients.jedis.Jedis.hgetAll(Jedis.java:851)

这解决了问题:

Jedis jedis = new Jedis(REDIS_MASTER_NODE, 6379, 1800);

推荐答案

如果你想要做的是设置 Jedis 连接 timeout，你应该使用专门为此制作的构造函数:>

If what you want to do is set Jedis connection timeout, you should do it using the special constructor made for that:

public Jedis(final String host, final int port, final int timeout)

您正在做的是在 Jedis 的 Redis 设置上设置 超时.做CONFIG SET timeout 60，意味着Redis将在60秒后关闭idle客户端连接.这就是为什么在 Jedis 中会出现异常的原因.

What you are doing is setting the timeout on Redis settings from Jedis. Doing CONFIG SET timeout 60, means that Redis will close idle client connections after 60 seconds. That's why you get the exception in Jedis.
