springboot+ehcache+redis集群

前面实现了二级缓存。接下来要实现redis集群模式。本地实现6380 6381 6382模拟三台redis节点组成的集群

修改大致如下:

(1)修改redis单机节点的相关配置变为集群的配置;

spring.redis.cluster.nodes=127.0.0.1:6380,127.0.0.1:6381,127.0.0.1:6382
spring.redis.cluster.timeout=1000
spring.redis.cluster.max-redirects=3
spring.redis.cluster.password=123456
#单redis服务器加载此配置
spring.redis.database = 0
#spring.redis.host=127.0.0.1
#spring.redis.port=6379
#连接超时时间
#最大活跃连接数
spring.redis.jedis.pool.max-active=10
#最大空闲连接数
spring.redis.jedis.pool.max-idle=5
#最长等待时间。-1不等待
spring.redis.jedis.pool.max-wait=-1
#最小空闲数0
spring.redis.jedis.pool.min-idle=0

(2) redis集群的相关配置：有原先单机节点配置变为集群配置使用了jedispoolconconfig

        factory.setDatabase(0);
        factory.setTimeout(clusterProperties.getTimeout());
        factory.setUsePool(true);
        return factory;
    }





}

(3)集群启动后直接测试就行。被人亲测过。没有问题
