创建jedis对象

　　1.先在taotao-parent的pom.xml中复制 以下内容到rest的pom.xml中

<!-- Redis客户端 -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>${jedis.version}</version>
</dependency>

2.创建jedis实例测试jedis

@Test
public void testJedis(){

//创建jedis对象

Jedis jedis = new Jedis("192.168.1.125",6379);

//调用jedis对象的方法,方法名和redis的命令一致

jedis.set("key1", "jedis test");
String string = jedis.get("key1");
System.out.println(string);
//关闭jedis

jedis.close();



}

 

 

//每次取资源都需要创建一个jedis对象，我们这里使用jedispool连接池
@Test
public void testJedisPool(){
//创建jedisPool连接池
JedisPool jedisPool = new JedisPool("192.168.1.125", 6379);
//从连接池中获取Jedis对象
Jedis jedis = jedisPool.getResource();

String string = jedis.get("key1");


System.out.println(string);

//每次用完必须关闭jedis，不然资源很快耗尽

jedis.close();
jedisPool.close();


}

 

// jedisCluster 集群版测试

@Test
public void testJedisCluster() {

HashSet<HostAndPort> nodes = new HashSet<>();
// 设置集群
nodes.add(new HostAndPort("192.168.1.125", 7001));
nodes.add(new HostAndPort("192.168.1.125", 7002));
nodes.add(new HostAndPort("192.168.1.125", 7003));
nodes.add(new HostAndPort("192.168.1.125", 7004));
nodes.add(new HostAndPort("192.168.1.125", 7005));
nodes.add(new HostAndPort("192.168.1.125", 7006));

JedisCluster cluster = new JedisCluster(nodes);

cluster.set("key1", "key1");

String string = cluster.get("key1");

System.out.println(string);

cluster.close();

}
