线上Redis突然间出现此问题
spring boot2.x版本默认redis连接池为lettuce，而以前的jedis是没有此问题的，
所以将lettuce换成jredis,因为通过用Wireshark发现jredis默认是发心跳包的,而lettuce是不发心跳包的,所以能保持连接状态,更改如下
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
<exclusions>
<exclusion>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</exclusion>
<exclusion>
<artifactId>lettuce-core</artifactId>
<groupId>io.lettuce</groupId>
</exclusion>
</exclusions>
</dependency>
<!-- jedis客户端 -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
<!-- spring2.X集成redis所需common-pool2，使用jedis必须依赖它-->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
</dependency>同事
同时yml文件也要进行修改
spring:
redis:
port: 6379
host: 127.0.0.1
jedis:
pool:
max-active: 8 #连接池的最大数据库连接数。设为0表示无限制
max-wait: -1 #最大建立连接等待时间。如果超过此时间将接到异常。设为-1表示无限制。
max-idle: 8 #最大空闲数
min-idle: 0
#redis 连接超时时间ms
timeout: 10000
database: 0
