1. Connection reset by peer lettuce: cluster: refresh: adaptive: true #20秒自动刷新一次 period: 20 spring.redis.jedis.pool.test-while-idle=true

2.重置连接池 lettuceConnectionFactory.initConnection(); lettuceConnectionFactory.resetConnection();`等获取、初始化、重置连接的方法

每次使用前都校验连接 @Bean public RedisTemplate<String, Object> myRedisTemplate(LettuceConnectionFactory factory) { RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>(); //解决redis每隔一段时间强制关闭远程连接的问题 factory.setValidateConnection(true); redisTemplate.setConnectionFactory(factory); Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class); // 设置 Key 和 Value 的序列化规则 redisTemplate.setKeySerializer(new StringRedisSerializer()); redisTemplate.setValueSerializer(jackson2JsonRedisSerializer); redisTemplate.setHashKeySerializer(new StringRedisSerializer()); redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer); // 初始化 RedisTemplate 序列化完成 redisTemplate.afterPropertiesSet(); return redisTemplate; }
