在Spring Boot 上配置Redis Cluster出现的异常

〇、背景

　　已在虚拟机（CentOS 7，在本文也称其为宿主机——即docker容器的宿主机）的docker中搭建好了6个节点的redis （host网络模式）集群：Docker Redis 5.0集群搭建

　　现在在本机（Windows 7）以Spring Boot环境连接集群

 

一、异常1：无法连接集群

1.配置：

1 #rediss
2 spring.redis.cluster.nodes=192.168.22.130:7001,192.168.22.130:7002,192.168.22.130:7003,192.168.22.130:7004,192.168.22.130:7005,192.168.22.130:7006
3 spring.redis.timeout=60000
4 spring.redis.jedis.pool.max-wait=-1
5 spring.redis.jedis.pool.max-active=300
6 spring.redis.jedis.pool.max-idle=100
7 spring.redis.jedis.pool.min-idle=20

2.报错：

org.springframework.data.redis.RedisConnectionFailureException: Unable to connect to Redis; nested exception is io.lettuce.core.RedisException: 
Cannot retrieve initial cluster partitions from initial URIs [RedisURI [host='192.168.22.130', port=7001], RedisURI [host='192.168.22.130', port=7002], RedisURI [host='192.168.22.130', port=7003],

4.解决

step(1)

　　因为spring-boot-starter-data-redis默认的redis客户端是使用lettuce，而上面我配置是jedis。

　　把配置中的jedis改为lettuce（当然选择 在pom文件中排除lettuce依赖，而使用jedis）

#rediss
spring.redis.cluster.nodes=192.168.22.130:7001,192.168.22.130:7002,192.168.22.130:7003,192.168.22.130:7004,192.168.22.130:7005,192.168.22.130:7006
spring.redis.timeout=60000
spring.redis.lettuce.pool.max-wait=-1
spring.redis.lettuce.pool.max-active=300
spring.redis.lettuce.pool.max-idle=100
spring.redis.lettuce.pool.min-idle=20

 

step(2) 注意在本机上看看能不能ping通所配置的redis集群节点

　　若ping不通，则需在本机添加到docker容器——redis集群节点的路由

　　windows命令行窗口下使用命令：route -p add 目标网络号 MASK 子网掩码 网关

　　例如：我的CentOS7ip配置如下：

       

 

　　并且我的redis配置时使用了host网络模式（即该容器共享了宿主机的网络命名空间，直接暴露在公共网络中，即通过宿主机ip+端口可访问该容器）。

　　所以在本机上加上路由信息：route -p add 192.168.22.0 MASK 255.255.255.0 172.17.0.2

　　再ping，便连通了。

 

step(3) 宿主机端口开放

　　注意在在本机上不仅要通过ip连得上虚拟机，并且得连接得到具体的端口（redis节点的端口）

　　在CentOS7虚拟机上使用 firewall-cmd --list-ports 命令查看防火墙开放的端口

　　若没有redis节点的端口，则使用 firewall-cmd --zone=public --add-port=80/tcp --permanent 命令开放redis各节点端口

　　使用 firewall-cmd --reload 重启防火墙

　　

 

 

 

 

二、异常2：找不到类GenericObjectPoolConfig

1.报错

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'redisConnectionFactory' defined in class path resource 
[org/springframework/boot/autoconfigure/data/redis/LettuceConnectionConfiguration.class]: Bean instantiation via factory method failed; 
nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory]: Factory method 
'redisConnectionFactory' threw exception; 
nested exception is java.lang.NoClassDefFoundError: org
/apache/commons/pool2/impl/GenericObjectPoolConfig

 

2.解决

添加连接池依赖

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-pool2 -->
    <dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-pool2</artifactId>
      <version>2.8.0</version>
    </dependency>
