Springcloud +redis集群

springcloud  中 springboot版本是2.X.X以上的,版本不同,集群对应的客户端api方法,连接池不一样.
 

具体操作可以看git上源码.

redis集群的配置比较简单.

添加jar:
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>
redis集群的配置文件:
redis:
    cache:
      cluster-nodes:
       192.168.200.X:X ,192.168.200.X:X 192.168.200.X:X ,192.168.200.X:X  ,192.168.200.X:X ,192.168.200.X:X
      # 执行命令超时时间
      command-timeout: 15000
      # 重试次数
      max-attempts: 5
      # 跨集群执行命令时要遵循的最大重定向数量
      max-redirects: 3
      # 连接池最大连接数（使用负值表示没有限制）
      max-active: 16
      # 连接池最大阻塞等待时间（使用负值表示没有限制）
      max-wait: -1
      # 连接池中的最大空闲连接
      max-idle: 8
      # 连接池中的最小空闲连接
      min-idle: 0
      # 是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个
      test-on-borrow: true
