redis command timed

Question

项目使用lettuce 客户端，双中心，在开启连接池可用性检测后问题有好转，但是另一个跨中心的访问一直报超时，检查了网络，性能。cpu,连接数，都正常，哪位朋友有啥好的办法，除了切换客户端外方法？
尝试的方案：查看redis 性能监控，显示正常
优化线程池，开启连接检测，开启后一个中心正常
查看网络，网络问题排除
有没有不切换客户端的方式进行解

Answer 1

连接超时，改下默认连接超时时长，示例：

import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.core.RedisTemplate;

// 获取RedisTemplate实例
RedisTemplate<String, String> redisTemplate = // 初始化RedisTemplate

// 获取Redis连接
RedisConnection connection = redisTemplate.getConnectionFactory().getConnection();

// 设置命令超时时间为5秒
connection.setTimeout(5000);

// 执行Redis命令
String result = connection.get("key");
