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
