建立jedis對象

　　1.先在taotao-parent的pom.xml中複製 如下內容到rest的pom.xml中

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

2.建立jedis實例測試jedis

@Test
public void testJedis(){

//建立jedis對象

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

//調用jedis對象的方法,方法名和redis的命令一致

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

jedis.close();



}

 

 

//每次取資源都須要建立一個jedis對象，咱們這裏使用jedispool鏈接池
@Test
public void testJedisPool(){
//建立jedisPool鏈接池
JedisPool jedisPool = new JedisPool("192.168.1.125", 6379);
//從鏈接池中獲取Jedis對象
Jedis jedis = jedisPool.getResource();

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


System.out.println(string);

//每次用完必須關閉jedis，否則資源很快耗盡

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


}

 

// jedisCluster 集羣版測試

@Test
public void testJedisCluster() {

HashSet<HostAndPort> nodes = new HashSet<>();
// 設置集羣
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();

}
