本文介绍了解决Redisson客户端在使用EVAL命令时遇到RedisConnectionClosedException的问题。通过升级Redisson版本并调整连接参数，特别是增加pingConnectionInterval的值，有效避免了因长时间未操作而导致的连接关闭。

报错内容

解决

pom

<dependency>
     <groupId>org.redisson</groupId>
      <artifactId>redisson-spring-boot-starter</artifactId>
      <version>3.9.1</version>
  </dependency>

redis版本
集群模式
在这里插入图片描述

原因

redis 的间隙过长，导致连接关闭

解决

设置ping的时长

pingConnectionInterval = 60000

@Bean
public RedissonClient getRedissonClient() {
    Config config = new Config();
    if (!org.apache.commons.lang3.StringUtils.isEmpty(slave)) {
        config.useSentinelServers()
                .setMasterName(masterName)
                .setPassword("".equals(password) ? null : password)
                .addSentinelAddress(getSlaves())
                .setPingConnectionInterval(60000);
    } else {
        config.useSingleServer()
                .setAddress("redis://" + host + ":" + port)
                .setPassword("".equals(password) ? null : password)
                .setPingConnectionInterval(60000);
    }
    return Redisson.create(config);
}
