一、項目必備Jar包
redis.clients jedis 2.9.0 commons-pool commons-pool 1.6 junit junit 4.12
二、實例與結(jié)構(gòu)
1）遠(yuǎn)程連接redis，清空數(shù)據(jù)庫 new Jedis(redis服務(wù)連接IP，端口)
重慶分公司
重慶分公司
private static Jedis jedis;
@Before
public void before(){
jedis= JedisConnectUtil.getJedis(JedisTest.URL,63**);
jedis.flushDB();
}2）String類型
@Test
public void testString(){
//設(shè)置鍵 獲取鍵 get set
jedis.set("steve","stevetao");
System.out.println("設(shè)置后值："+jedis.get("steve"));
//追加鍵 append
jedis.append("steve"," Is Good Man");
System.out.println("追加后值："+jedis.get("steve"));
//刪除操作 del
jedis.del("steve");
System.out.println("刪除后值："+jedis.get("steve"));
//不存在就保存， setnx msetnx
jedis.setnx("steve","stevetao");
System.out.println("設(shè)置后值："+jedis.get("steve"));
System.out.println("再次設(shè)置后值："+jedis.setnx("steve","stevetao"));
//截取字符串 substr
System.out.println("截取后值："+jedis.substr("steve",0,4));
//設(shè)置多個鍵值對 mset mget
jedis.mset(new String[]{"zhangsan","123","lisi","1234"});
System.out.println("多次設(shè)置后值："+jedis.mget("zhangsan","lisi"));
//遞增遞減 incr decr incrby decrby
jedis.incr("zhangsan");
jedis.decr("lisi");
System.out.println("遞增遞減后值："+jedis.mget("zhangsan","lisi"));
jedis.incrBy("zhangsan",6);
jedis.decrBy("lisi",3);
System.out.println("遞增遞減后值："+jedis.mget("zhangsan","lisi"));
} 
3）List類型
@Test
public void testList(){
//尾添加 rpush 頭添加 lpush
jedis.lpush("books","java","C++","Ruby","Scala","python");
jedis.rpush("language","java","C++","Ruby","Scala","python");
// -1 表示列表的最后一個元素， -2 表示列表的倒數(shù)第二個元素，以此類推。
System.out.println("頭添加后books值:"+jedis.lrange("books",0,-1));
System.out.println("尾添加后language值:"+jedis.lrange("language",0,-1));
//尾部刪除 rpop 頭部刪除 lpop
System.out.println("刪除的值為："+jedis.lpop("books"));
System.out.println("刪除的值為："+jedis.rpop("language"));
System.out.println("頭部刪除后books值:"+jedis.lrange("books",0,-1));
System.out.println("尾部刪除后language值:"+jedis.lrange("language",0,-1));
//尾部刪除并頭添加 rpoplpush
jedis.rpoplpush("language","books");
System.out.println("尾部刪除并頭添加后books值:"+jedis.lrange("books",0,-1));
System.out.println("尾部刪除并頭添加后language值:"+jedis.lrange("language",0,-1));
//區(qū)別: 只能給存在的list做添加，不能項lpush那樣能新增list
jedis.lpushx("books","php");
jedis.lpushx("book","php");
System.out.println("頭添加后books值:"+jedis.lrange("books",0,-1));
System.out.println("頭添加后book值:"+jedis.lrange("book",0,-1));
//獲取集合長度 llen 指定索引的值 lindex 保留截取的值 ltrim
System.out.println("books集合長度:"+jedis.llen("books"));
System.out.println("books集合第二個數(shù)值:"+jedis.lindex("books",1));
jedis.ltrim("books",0,2);
System.out.println("截取后books值:"+jedis.lrange("books",0,-1));
} 
4）Hash類型
@Test
public void testHash(){
//適合字段：設(shè)值hset 取值hget（如果value是json字符串，類似保存對象）
jedis.hset("student","name","zhangsan");
System.out.println("student中name的值為："+jedis.hget("student","name"));
//適合對象：設(shè)值hmset 取值hmget
Map map = new HashMap();
map.put("name", "lisi");
map.put("age", "36");
jedis.hmset("teacher",map);
System.out.println("teacher中name、age的值為："+jedis.hmget("teacher","name","age"));
//teacher是否存在鍵age hexists
if(jedis.hexists("teacher","age")){
//給指定值增加4 hincrBy
jedis.hincrBy("teacher","age",4);
System.out.println("teacher中name、age的值為："+jedis.hmget("teacher","name","age"));
}
//返回key的個數(shù)hlen 返回值hvals 返回鍵hkeys 鍵值對hgetAll
jedis.hset("student","age","13");
jedis.hset("student","qq","2246920330");
jedis.hset("student","address","beijing");
System.out.println("student中鍵的個數(shù)為："+jedis.hlen("student"));
System.out.println("student中所有的鍵為："+jedis.hkeys("student"));
System.out.println("student中所有的值為："+jedis.hvals("student"));
System.out.println("student中所有的鍵值對為："+jedis.hgetAll("student"));
//刪除 hdel
jedis.hdel("student",new String[]{"address","qq","age"});
System.out.println("刪除后，student中所有的鍵值對為："+jedis.hgetAll("student"));
} 
5）Set類型
@Test
public void testSet(){
//set中添加值 sadd 取值 smembers
jedis.sadd("student","Jan","John","Steve","jack","lili","peter","Anna");
jedis.sadd("girls","Jan","lili","Alice","Jeanne","Anna");
System.out.println("排名不分先后："+jedis.smembers("student"));
//set個數(shù) scard 是否存在某個值 sismember
System.out.println("set集合的個數(shù)："+jedis.scard("student"));
System.out.println("student是否存在steve："+jedis.sismember("student","Steve"));
System.out.println("student是否存在stevetao："+jedis.sismember("student","Stevetao"));
//System.out.println(jedis.sscan("student","0").getResult());
//刪除指定的值 srem 隨機刪除并返回 spop
System.out.println("刪除指定的值Steve："+jedis.srem("student","Steve"));
System.out.println("刪除的值為："+jedis.spop("student"));
System.out.println("再次排名不分先后："+jedis.smembers("student"));
//集合操作
System.out.println("兩個set的交集："+jedis.sinter("student","girls"));
System.out.println("兩個set的并集："+jedis.sunion("student","girls"));
System.out.println("student對girls的差集："+jedis.sdiff("student","girls"));
System.out.println("girls對student的差集："+jedis.sdiff("girls","student"));
//集合操作并保存
jedis.sinterstore("jiaoji","student","girls");
jedis.sunionstore("bingji","student","girls");
jedis.sdiffstore("chaji","student","girls");
System.out.println("交集："+jedis.smembers("jiaoji"));
System.out.println("并集："+jedis.smembers("bingji"));
System.out.println("student對girls的差集："+jedis.smembers("chaji"));
} 
6）ZSet類型
@Test
public void testZset(){
jedis.zadd("math",75,"Jim");
jedis.zadd("math",86,"Lina");
jedis.zadd("math",52,"Dive");
jedis.zadd("math",91,"Bobber");
System.out.println("有序集合的成員數(shù):"+jedis.zcard("math"));
System.out.println("有序集合的成員:"+jedis.zrevrangeByScore("math",100,0));
//返回set
System.out.println("有序集合的成員:"+jedis.zrangeWithScores("math",0,100));
}
