Java 项目中使用 Redis 集群操作
1. 直接操作
2. 使用Spring
配置applicationContext.xml

测试集群

private ApplicationContext applicationContext; @Before public void init() { //初始化IOC容器 applicationContext = new ClassPathXmlApplicationContext( "classpath:applicationContext.xml"); }
// redis集群 @Test public void testJedisCluster() { JedisCluster jedisCluster = (JedisCluster) applicationContext .getBean("jedisCluster");
jedisCluster.set("name", "zhangsan"); String value = jedisCluster.get("name"); System.out.println(value); } |
