如何使用Jedis连接Redis

1.1 导入需要的依赖

<dependencies>
    <!-- 1、Jedis -->
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>3.7.1</version>
    </dependency>
    <!--    2、 Junit测试-->
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency>
    <!-- 3、 Lombok -->
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.24</version>
    </dependency>
</dependencies>

1.2 测试

import redis.clients.jedis.Jedis;

public class TestJedisConnection {
    // Redis服务器信息
    private static final String REDIS_HOST = "192.168.200.141";
    private static final int REDIS_PORT = 6379;
    private static final String REDIS_PASSWORD = "sl183691";

    public static void main(String[] args) {
        //1. 连接Redis
        Jedis jedis = new Jedis(REDIS_HOST, REDIS_PORT);
        jedis.auth(REDIS_PASSWORD);

        //2. 操作Redis - Redis的命令是什么，Jedis的方法就是什么
        jedis.set("city", "Shanghai");

        //2. 获取操作结果
        String value = jedis.get("city");
        System.out.println(value);

        //3. 释放资源
        jedis.close();
    }
}
