What are the commands for Redis, Jedis? How to set up a firewall

Run the following code on Linux:

Single instance: Jedis instance:

 PackageCom.jedis.demo;Importorg.junit.Test;ImportRedis.clients.jedis.Jedis; Public classDemo1 {/** Single Instance connection to Redis database **/@Test Public voidrun () {//parameters: IP address, port numberJedis jedis=NewJedis ("192.168.239.137", 6379); Jedis.set ("Name", "Zhang San"); System.out.println (The value of "name" is: "+jedis.get (" name ")); }}

Jedis Connection Pool

/** Jedis Connection Pool **/@Test Public voidrun2 () {//1. Setting the connection pool configuration object        jedispoolconfig config=new jedispoolconfig (); //set the maximum number of connections in the pool "optional"        Config.setmaxtotal (); //set the maximum number of connections retained in the pool when idle "optional"        Config.setmaxidle (ten); //Setting up Connection Objects        jedispool pool=new jedispool (config, "192.168.239.137", 6379); //get the Connection object in the pool        Jedis jedis= Pool.getresource (); System.out.println (The value of "name" is: "+jedis.get (" name ")); //connect to the return pool jedis.close (); }

Extract Connection Pooling Tool

To facilitate the use of connection pooling, extract the connection pooling tool:

 PackageCom.jedis.demo;ImportRedis.clients.jedis.Jedis;ImportRedis.clients.jedis.JedisPool;ImportRedis.clients.jedis.JedisPoolConfig; Public classJedisutill {//Define a Connection pool object ()    Private Final StaticJedispool POOL; //initializing a connection pool object inside a static block of code    Static {        //1. Setting the connection pool configuration objectJedispoolconfig config=NewJedispoolconfig (); //set the maximum number of connections in the pool "optional"Config.setmaxtotal (50); //set the maximum number of connections retained in the pool when idle "optional"Config.setmaxidle (10); //Setting up Connection ObjectsPool=NewJedispool (config, "192.168.239.137", 6379); }        /** Get connections from the pool **/     Public StaticJedis Getjedis () {returnPool.getresource (); }}
