Redis Java Client Jedis

Jedis客户端

Maven工程导入Jedis依赖的jar包

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.8.0</version>
<type>jar</type>
<scope>compile</scope>
</dependency>

<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>

创建测试类

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"));

}
}
