第7章 Redis_Jedis_测试

7.1 Jedis所需要的jar包

 

 

7.2 连接Redis注意事项

禁用Linux的防火墙：Linux(CentOS7)里执行命令

systemctl stop/disable firewalld.service   

redis.conf中注释掉bind 127.0.0.1 ,然后 protected-mode no

 

7.3 Jedis常用操作

7.3.1 创建动态的工程

 

7.3.2 创建测试程序

package com.atguigu.jedis;

import redis.clients.jedis.Jedis;

public class Demo01 {

　　public static void main(String[] args) {

　　　　Jedis jedis = new Jedis("192.168.137.3",6379);

　　　　String pong = jedis.ping();

　　　　System.out.println("连接成功："+pong);

　　　　jedis.close();

　　}

}

 

 

 

7.4 测试相关数据类型

 

7.4.1 Jedis-API:    Key

 

 

jedis.set("k1", "v1");

 

jedis.set("k2", "v2");

 

jedis.set("k3", "v3");

 

Set<String> keys = jedis.keys("*");

 

System.out.println(keys.size());

 

for (String key : keys) {

 

　　System.out.println(key);

 

}

 

System.out.println(jedis.exists("k1"));

 

System.out.println(jedis.ttl("k1"));                

 

System.out.println(jedis.get("k1"));

 

 

 

7.4.2 Jedis-API:    String

 

jedis.mset("str1","v1","str2","v2","str3","v3");

System.out.println(jedis.mget("str1","str2","str3"));

 

7.4.3 Jedis-API:    List

List<String> list = jedis.lrange("mylist",0,-1);

for (String element : list) {

　　System.out.println(element);

}

 

7.4.4 Jedis-API:    set

jedis.sadd("orders", "order01");

jedis.sadd("orders", "order02");

jedis.sadd("orders", "order03");

jedis.sadd("orders", "order04");

Set<String> smembers = jedis.smembers("orders");

for (String order : smembers) {

　　System.out.println(order);

}

jedis.srem("orders", "order02");

 

7.4.5 Jedis-API:    hash

jedis.hset("hash1","userName","lisi");

System.out.println(jedis.hget("hash1","userName"));

Map<String,String> map = new HashMap<String,String>();

map.put("telphone","13810169999");

map.put("address","atguigu");

map.put("email","abc@163.com");

jedis.hmset("hash2",map);

List<String> result = jedis.hmget("hash2", "telphone","email");

for (String element : result) {

　　System.out.println(element);

}

 

 

7.4.6 Jedis-API:    zset

 

 

jedis.zadd("zset01", 100d, "z3");

 

jedis.zadd("zset01", 90d, "l4");

 

jedis.zadd("zset01", 80d, "w5");

 

jedis.zadd("zset01", 70d, "z6");

 

 

 

Set<String> zrange = jedis.zrange("zset01", 0, -1);

 

for (String e : zrange) {

 

　　System.out.println(e);

 

}
