检查连接Redis [英] Check connection Redis

问题描述

我正在使用 Jedis 客户端在 Java 中使用 Redis.我正在创建一个 JedisPool，想知道连接是否成功，有没有办法在不获取对象的情况下做到这一点?

I am using the Redis in Java using the Jedis client. I am creating a JedisPool and would like to know if the connection is successful, is there a way of doing this without fetching an object?

推荐答案

您可以尝试从 JedisPool 获取 Jedis 资源.如果连接尚未建立，将抛出 JedisConnectionException:

You can attempt to get the Jedis resource from the JedisPool. A JedisConnectionException will be thrown if a connection has not been established:

JedisPool pool = new JedisPool(...);
try {
    Jedis jedis = pool.getResource();
    // Is connected
} catch (JedisConnectionException e) {
    // Not connected
}
