IntelliJ IDEA连接Redis全攻略：从Lettuce集成到插件调试 Redis作为高性能的键值对内存数据库，其核心原理基于内存存储和丰富的数据结构，为应用提供了极低延迟的数据访问能力。这一特性使其在缓存、会话存储和消息队列等场景中具有极高的技术价值，成为现代分布式系统架构的关键组件。在Java开发领域，通过Spring Data Redis集成Lettuce客户端，开发者可以便捷地在应用中实现与Redis的交互。本文聚焦于在IntelliJ IDEA这一主流集成开发环境中，如何高效配置连接池与序列化方案，并利用可视化插件进行实时数据调试，从而优化开发工作流，提升工程实践效率阅读详情

redis本地可以取值也可以设值,阿里云的端口已开7001-7006 17001-17006

@Test
public void testJedis3() throws IOException {
Set<HostAndPort> nodes = new HashSet<>();
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));

JedisCluster jedisCluster = new JedisCluster(nodes);
jedisCluster.set("name", "1234");
System.out.println(jedisCluster.get("name"));
jedisCluster.close();
}[/code]
成功取值 1234

@Test
public void testJedis3() throws IOException {
Set<HostAndPort> nodes = new HashSet<>();
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));
nodes.add(new HostAndPort(ip, host));

JedisCluster jedisCluster = new JedisCluster(nodes);
jedisCluster.set("ggg", "1234");
System.out.println(jedisCluster.get("ggg"));
jedisCluster.close();
}[/code]
报错
