Jedis客户端

• Jedis客户端是Redis官方推荐使用的Java客户端之一

---

Maven工程导入Jedis依赖的jar包

<dependency>
    <groupId>redis.clientsgroupId>
    <artifactId>jedisartifactId>
    <version>2.8.0version>
    <type>jartype>
    <scope>compilescope>
dependency>

提示：这里我们使用2.8版本的jedis

---

• 作为测试，我们把junit的jar包也导入进来

<dependency>
    <groupId>junitgroupId>
    <artifactId>junitartifactId>
    <version>4.11version>
    <scope>testscope>
dependency>

---

创建测试类

• JedisTest.java

import org.junit.BeforeClass;
import org.junit.Test;

import redis.clients.jedis.Jedis;
/**
 * Jedis简单使用
 * @author LingDu
 */
public class JedisTest {
    private static final String HOST = "192.168.20.33"; //redis主机地址
    private static final int PORT = 6379;               //redis端口
    private static final String PASSWORD = "123456";    //redis认证密码
    private static Jedis jedis;

    @BeforeClass
    public static void init(){
        jedis = new Jedis(HOST, PORT);
        //权限认证，如果redis设置了密码，需要认证密码，反之可省略认证
        System.out.println(jedis.auth(PASSWORD));
    }


    /**
     * Redis对字符串的操作
     */
    @Test
    public void testString() {

        jedis.set("a1", "hello world");//设置key-value
        System.out.println("获取值：" + jedis.get("a1")); //取出对应key的value

        jedis.append("a1", "hello redis");//拼接到对应key的value后面
        System.out.println("拼接值：" + jedis.get("a1"));

        jedis.del("a1");//删除某个key
        System.out.println("删除key之后的结果：" + jedis.get("a1"));

        jedis.mset("name","LingDu","age","18");//设置多个key-value
        System.out.println("name：" + jedis.get("name") + " , " + "age：" + jedis.get("age"));

        jedis.incr("age");//进行加1操作
        System.out.println("加1之后的age：" + jedis.get("age"));

    }
}
