redis之Java Jedis 的使用(使用maven引入)

maven 依赖：

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.2.0</version>
</dependency>

 

jedis 的操作的 api 跟 redis-cli 命令行极其相似

import redis.clients.jedis.Jedis;

import java.util.*;


public class TestRedis {
public static void main(String[] args) {
//ip 端口
Jedis jedis = new Jedis("你的 ip", 6379);
//密码
jedis.auth("mypassword");
//测试连接
String ping = jedis.ping();
System.out.println(ping);
//jedis 使用数据库 1
jedis.select(1);
//字符串存取
String set = jedis.set("k1", "k2");
System.out.println(set);
String k1 = jedis.get("k1");
System.out.println(k1);
//不存在的键
System.out.println(jedis.get("k5"));
//键是否存在
System.out.println(jedis.exists("k5"));
//键遍历
Set<String> keys = jedis.keys("*");
for (Iterator iterator = keys.iterator(); iterator.hasNext();) {
String key = (String) iterator.next();
System.out.println(key);
}
//批量存取
jedis.mset("test-redis-str1","v1","test-redis-str2","v2","test-redis-str3","v3");
System.out.println(jedis.mget("test-redis-str1","test-redis-str2","test-redis-str3"));
//set
jedis.sadd("orders","jd001");
jedis.sadd("orders","jd002");
jedis.sadd("orders","jd003");
Set<String> set1 = jedis.smembers("orders");
for (Iterator iterator = set1.iterator(); iterator.hasNext();) {
String string = (String) iterator.next();
System.out.println(string);
}
jedis.srem("orders","jd002");
Set<String> set2 = jedis.smembers("orders");
for (Iterator iterator = set2.iterator(); iterator.hasNext();) {
String string = (String) iterator.next();
System.out.println(string);
}
//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);
}
//zset
jedis.zadd("zset01",60d,"v1");
jedis.zadd("zset01",70d,"v2");
jedis.zadd("zset01",80d,"v3");
jedis.zadd("zset01",90d,"v4");
Set<String> s1 = jedis.zrange("zset01",0,-1);
for (Iterator iterator = s1.iterator(); iterator.hasNext();) {
String string = (String) iterator.next();
System.out.println(string);
}


}
