springboot2.3以上版本可添加配置解决。 lettuce:cluster:refresh:adaptive: trueperiod: 20
每次链接都进行自动校验
Component
Slf4j
public class LettuceConnectionValidConfig implements InitializingBean {Autowiredprivate RedisConnectionFactory redisConnectionFactory;Overridepublic void afterPropertiesSet() throws Exception {if(redisConnectionFactory instanceof LettuceConnectionFactory){LettuceConnectionFactory c(LettuceConnectionFactory)redisConnectionFactory;c.setValidateConnection(true);}}
}定时任务
Component
Slf4j
public class LettuceConnectionValidTask {Autowiredprivate RedisConnectionFactory redisConnectionFactory;Scheduled(cron0/2 * * * * ?)public void task() {if(redisConnectionFactory instanceof LettuceConnectionFactory){LettuceConnectionFactory c(LettuceConnectionFactory)redisConnectionFactory;c.validateConnection();}}
}
排除lettuce采用jedis。 dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-data-redis/artifactIdexclusionsexclusiongroupIdio.lettuce/groupIdartifactIdlettuce-core/artifactId/exclusion/exclusions/dependencydependencygroupIdredis.clients/groupIdartifactIdjedis/artifactId/dependency
