Jedis Test Case ​

Jedis所需要的jar包 ​

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

连接Redis注意事项 ​

shell
禁用Linux的防火墙：Linux(CentOS7)里执行命令
ystemctl stop/disable firewalld.service  
redis.conf中注释掉bind 127.0.0.1 ,然后 protected-mode no

Jedis常用操作 ​

创建动态的工程 ​

创建测试程序 ​

java
 public static void main(String[] args) {
    //创建Jedis对象
    Jedis jedis=new Jedis("192.168.117.134",6379);

    String pong = jedis.ping();
    System.out.println("--------------------->"+pong);
 }

测试相关数据类型 ​

Jedis-API: Key ​

java
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"));

Jedis-API: String ​

java
jedis.mset("str1","v1","str2","v2","str3","v3");
System.out.println(jedis.mget("str1","str2","str3"));

Jedis-API: List ​

java
List<String> list = jedis.lrange("mylist",0,-1);
for (String element : list) {
System.out.println(element);
}

Jedis-API: set ​

java
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");

Jedis-API: hash ​

java
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);
}

Jedis-API: zset ​

java
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);
}
