Jedis操作hash和Jedis操作List

Jedis操作hash和Jedis操作List

• 哈希类型 hash ：map个时间哦
  • hset
  • hget
  • hgetAll

package com.ailyt.jiedis.test;

import org.junit.Test;
import redis.clients.jedis.Jedis;

import java.util.Map;
import java.util.Set;

public class JedisTest {

    @Test
    public void MyTest01() {
        //获取连接
        Jedis jedis = new Jedis("localhost",6379);
        //操作
//        jedis.set("username", "zhangsan");
//        String set = jedis.set("password", "root");
//        System.out.println(set);

        long del1 = jedis.del("username");//1

        System.out.println(del1);
        System.out.println(del2);

        Set<String> keys = jedis.keys("*");
        System.out.println(keys.toString());

        //关闭连接
        jedis.close();
    }


    /**

    @Test
    public void MyTest02() {
        Jedis jedis = new Jedis("localhost",6379);

        long hset1 = jedis.hset("user", "name", "张三");
        long hset2 = jedis.hset("user", "age", "21");
        long hset3 = jedis.hset("user", "gender", "男");
        System.out.println(hset1);
        System.out.println(hset2);
        System.out.println(hset3);


        String hget = jedis.hget("user", "name");
        System.out.println(hget);

        Map<String, String> user = jedis.hgetAll("user");
        user.forEach((s, s2) -> {
            System.out.println(s+"--->"+s2);
        });
    }
}

• 列表类型list：linkedlist格式，支持重复元素
  • lpush/rpush
  • lpop/rpop
