Getting PING response with JedisPooled

[dmcauslan]

I use the result of PING as part of an app's health endpoint.

With JedisPooled it looks like the only way to call PING is to use a protocol command, and the result seems to be an anonymous class. Is there a way to determine whether the command was successful or failed, and to get the "HELLO" response back?

Kotlin 1.6.21
Java 17.0.2
Jedis 4.2.3
Redis 6.2.5

import redis.clients.jedis.JedisPooled
import redis.clients.jedis.Protocol

val jedis = JedisPooled("localhost", 6379)
val result = jedis.sendCommand(Protocol.Command.PING, "HELLO")
result.javaClass

>>> class [B

SafeEncoder.encode((byte[]) result) should give you the "HELLO".

Besides that, you can provide PooledConnectionProvider with which would have more control. Here is the Java code:

PooledConnectionProvider provider = new PooledConnectionProvider(...);
JedisPooled jedis = new JedisPooled(provider);
try (Connection connection = provider.getConnection()) {
  connection.ping();
}

@sazzad16 That worked, thanks!

Did I miss that in the docs somewhere?

import redis.clients.jedis.JedisPooled
import redis.clients.jedis.Protocol
import redis.clients.jedis.util.SafeEncoder

val jedis = JedisPooled("localhost", 6379)
val result = jedis.sendCommand(Protocol.Command.PING, "HELLO")
val stringResult = SafeEncoder.encode(result as ByteArray)
stringResult

>>> HELLO
