lettuce RedisCommandTimeoutException

RedisCommandTimeoutException是Lettuce Redis客户端中的异常，表示Redis命令执行超时。当Redis命令执行时间超过了Lettuce客户端配置的超时时间时，就会抛出该异常。

以下是一个使用Lettuce Redis客户端执行Redis命令并处理RedisCommandTimeoutException异常的示例：

import io.lettuce.core.RedisClient;
import io.lettuce.core.RedisCommandTimeoutException;
import io.lettuce.core.api.StatefulRedisConnection;
import io.lettuce.core.api.sync.RedisCommands;

public class LettuceExample {
    public static void main(String[] args) {
        RedisClient redisClient = RedisClient.create("redis://localhost");
        StatefulRedisConnection<String, String> connection = redisClient.connect();
        RedisCommands<String, String> syncCommands = connection.sync();

        try {
            // 设置超时时间为1毫秒
            syncCommands.setTimeout(1);

            // 执行Redis命令
            syncCommands.get("key");

        } catch (RedisCommandTimeoutException e) {
            // 处理RedisCommandTimeoutException异常
            System.out.println("Redis command timed out!");
        }

        connection.close();
        redisClient.shutdown();
    }
}
