springboot-redis连接超时问题

1. 使用spring-boot-starter-data-redis时长时间不使用会出现连接超时问题
2. 启动类添加@EnableScheduling注解
3. 添加commons-pool2依赖

    <dependency>
      <groupId>org.apache.commonsgroupId>
      <artifactId>commons-pool2artifactId>
   dependency>
   

4. 开启可验证配置

   @Slf4j
   @Component
   public class LettuceConnectionValidConfig implements InitializingBean {
       private final RedisConnectionFactory redisConnectionFactory;
   
       public LettuceConnectionValidConfig(RedisConnectionFactory redisConnectionFactory) {
           this.redisConnectionFactory = redisConnectionFactory;
       }
   
       @Override
       public void afterPropertiesSet() throws Exception {
           if(redisConnectionFactory instanceof LettuceConnectionFactory){
               LettuceConnectionFactory c= (LettuceConnectionFactory)redisConnectionFactory;
               c.setValidateConnection(true);
           }
       }
   }
   

5. 配置定时任务

   @Slf4j
   @Component
   public class LettuceConnectionValidTask   {
       private final RedisConnectionFactory redisConnectionFactory;
   
       public LettuceConnectionValidTask(RedisConnectionFactory redisConnectionFactory) {
           this.redisConnectionFactory = redisConnectionFactory;
       }
   
       @Scheduled(cron="0/2 * * * * ?")
       public void task() {
           if(redisConnectionFactory instanceof LettuceConnectionFactory){
               LettuceConnectionFactory c=(LettuceConnectionFactory)redisConnectionFactory;
               c.validateConnection();
           }
       }
   }
