JedisCluster 基本代码__写给自己看的_jediscluster jc = new jediscluster(hs);-优快云博客

本文介绍如何在Spring Boot项目中配置并使用Redis Cluster集群。通过示例代码展示了如何从属性文件读取集群节点信息，并设置连接池参数，最终创建JedisCluster实例。此配置可以作为Spring Boot应用集成Redis集群的基础。

主要代码
Set<HostAndPort> jedisClusterNodes = Sets.newHashSet();
for (String hps : redisProperties.getAddressList()) {
String[] hp = hps.split(":");
jedisClusterNodes.add(new HostAndPort(hp[0], Integer.parseInt(hp[1])));
}
GenericObjectPoolConfig config = new GenericObjectPoolConfig();
config.setMaxIdle(redisProperties.getMaxIdle());
config.setMaxTotal(redisProperties.getMaxTotal());
config.setMaxWaitMillis(redisProperties.getMaxWaitMillis());
config.setMinIdle(redisProperties.getMinIdle());
config.setTestWhileIdle(true);
JedisCluster jc = new JedisCluster(jedisClusterNodes, Protocol.DEFAULT_TIMEOUT, config);
return jc;

-----------------------------------用springboot@Bean注入到spring中去
