redis 入门学习-- java API操作redis

Java连接redis的工具包有很多，这里我选择使用Jedis进行连接。连接很简单，如下：

package mjy;

import java.util.HashMap;
import java.util.Map;

import redis.clients.jedis.Jedis;

public class RedisClientConnectionTest {
    public static void main(String[] args) {
        // 构造一个redis的客户端对象
        Jedis jedis = new Jedis("mini1", 6379);
        String ping = jedis.ping();
        System.out.println(ping);
        
        //插入value为string的记录
        long result = jedis.sadd("session", "server0002");
        System.out.println(result);
        
        //插入value为list的记录
        long result_1 = jedis.lpush("servers", "server1","server2","server3");
        System.out.println(result_1);
        
        //插入value为set的记录
        long result_2 = jedis.sadd("aaa", "aaa1","aaa2","aaa3");
        System.out.println(result_2);
        
        //插入value为hash的记录
        Map<String , String> hashMap = new HashMap<String , String>();
        hashMap.put("001", "zhangsan");
        hashMap.put("002", "lishi");
        hashMap.put("003", "wangwu");
        String result_3 = jedis.hmset("hash_key", hashMap);
        System.out.println(result_3);
        
        //插入value为zset的记录
        Map<String , Double> hMap = new HashMap<String , Double>();
        hMap.put("zhangsan", 1.0);
        hMap.put("lishi", 2.0);
        hMap.put("wangwu", 3.0);
        long result_4 = jedis.zadd("zset_key", hMap);
        System.out.println(result_4);
        
    }
}

测试结果如下：
