Use of Jedis (Java+redis) pool

Try it today. The use of connection pool jedispool in Jedis. The code is as follows:

 PackageCom.myapp.jedis.pooldemo;ImportRedis.clients.jedis.Jedis;ImportRedis.clients.jedis.JedisPool;ImportRedis.clients.jedis.JedisPoolConfig;/*** Created by Baidu on 16/10/18.*/ Public classTestpool {Private StaticJedispool pool =NULL;  Public StaticJedispool Getpool () {if(Pool = =NULL) {jedispoolconfig config=NewJedispoolconfig (); Config.setmaxtotal (500); Config.setmaxidle (5); Config.setmaxwaitmillis (1000*10); //whether validate operations are performed in advance when a Jedis instance is borrow, and if true, the resulting Jedis instances are available;Config.settestonborrow (true); //new Jedispool (config, ADDR, PORT, TIMEOUT, AUTH);Pool =NewJedispool (config, "[IP]", 8379, 10000, "[Auth]"); }        returnPool; }     Public synchronized StaticJedis getresource () {if(Pool = =NULL) {Pool=Getpool (); }        returnPool.getresource (); }    //return to Connection pool//Deprecated//when you're done, redis.close ()    /*Public static void Returnresource (Jedis redis) {if (Redis! = null) {Pool.returnresource (Redis)        ; }    }    */     Public Static voidMain (string[] args) {Jedis Redis=NULL; intloop = 1;  while(Loop < 20) {            Try {                LongStart =System.currenttimemillis (); Redis=getresource (); Redis.set ("K1", "v1"); String ret= Redis.get ("K1"); LongEnd =System.currenttimemillis (); System.out.printf ("Get ret from Redis:%s with%d millis\n", ret, end-start); } finally {                if(Redis! =NULL) {redis.close (); }} Loop++; }    }}

Among them, there is a function returnresource has been deprecated, now Jedis the Close method rewrite, with Jedis.close to release resources.

Ran 20 times, the result of the operation is as follows:

Get ret from REDIS:V1 with564 MillisGet ret from Redis:v1 with235 MillisGet ret from Redis:v1 with225millisget ret from Redis:v1 with214millisget ret from Redis:v1 with210millisget ret from Redis:v1 with232millisget ret from Redis:v1 with209millisget ret from Redis:v1 with211millisget ret from Redis:v1 with239millisget ret from Redis:v1 with207millisget ret from Redis:v1 with215millisget ret from Redis:v1 with223millisget ret from Redis:v1 with291millisget ret from Redis:v1 with220millisget ret from Redis:v1 with214millisget ret from Redis:v1 with219millisget ret from Redis:v1 with257millisget ret from Redis:v1 with214millisget ret from Redis:v1 with211Millisprocess finished with exit code0

As you can see, the first time is more than 500 milliseconds, followed by more than 200 milliseconds, the speed has improved.
