Java使用Jedis连接Redis实现,你好，世界！

Jedis

 Jedis是Java连接Redis的连接池。

Jedis与Java整合

1.步骤

1.连接redis
Jedis jedis = new Jedis("127.0.0.1",6379);
2.操作redis
//redis存储和取值操作
3.关闭连接
jedis.close();

2.具体实现

 添加pom配置文件

 <!-- 添加redis依赖 -->
  <dependency>
  <groupId>redis.clients</groupId>
  <artifactId>jedis</artifactId>
  <version>2.9.0</version>
 </dependency>

 具体实现代码

import redis.clients.jedis.Jedis;
public class JedisTest {
    
    
    public static void main(String[] args) {
    
    
        //1.连接redis
        Jedis jedis = new Jedis("127.0.0.1",6379);
        //操作redis
        jedis.set("title","你好，世界！");
        String name = jedis.get("title");
        System.out.println(name);
        //3.关闭连接
        jedis.close();
    }
}

## Java与Redis中的List类型演示

    public static void toList(){
    
    
        //1.连接redis
        Jedis jedis = new Jedis("127.0.0.1",6379);
        //操作redis
        jedis.lpush("list1","a","b","c");
        jedis.rpush("list1","w");
        List<String> stringList = jedis.lrange("list1",0,-1);
        for (String list2: stringList) {
    
    
            System.out.println(list2);
        }
        System.out.println(jedis.llen("list1"));
        //3.关闭连接
        jedis.close();
    }

Java与Redis中的Hash类型演示

    //Hash类型
    public static void toHash(){
    
    
        //1.连接redis
        Jedis jedis = new Jedis("127.0.0.1",6379);
        //操作redis
        jedis.hset("hash1","a1","a1");
        jedis.hset("hash1","a2","a2");
        jedis.hset("hash1","a3","a3");
        Map<String,String> hash1 = jedis.hgetAll("hash1");
        System.out.println(hash1);
        System.out.println(jedis.hlen("hash1"));
    }
