Introduction Jedis use of

 　　Jedis operation Redis is a Java implementation of the API set, not too much should be noted, you can refer to this blog, understand the use of Jedis operating Redis related API, Java operations using Jedis redis

 

 

Redis connection Pools

　　Redis connection pool, it can be said Jedis connection pool because the pool is to create a connection, use and release using the Jedis API Java implementation.

　　Redis is not just cache, he was a database, but is a rather special database only (NoSQL), so Redis connection pool and database connection pool (such as Druid, C3P0, DBCP), the principles are similar.

 

 

Create a connection pool configuration file

　　Create a configuration file, the file name and path at random, I've named redis_pool.properties, stored in the classpath directory of the project, as follows:

redis_maxTotal = 30 
redis_maxIdle = 15 
redis_minIdle = 5 
redis_ip = 127.0.0.1 
redis_port = 6379

　　

 

Creating and using a connection pool Redis

Import java.io.IOException; 
Import a java.io.InputStream; 
Import the java.util.Properties; 

Import redis.clients.jedis.Jedis; 
Import redis.clients.jedis.JedisPool; 
Import redis.clients .jedis.JedisPoolConfig;

		// set parameters Redis Pool 
		JedisPoolConfig poolConfig new new JedisPoolConfig = (); 
		poolConfig.setMaxTotal (maxTotal); 
		poolConfig.setMaxIdle (maxIdle); 
		poolConfig.setMinIdle (MinIdle); 
		
		/ / Create jedis connection pool 
		JedisPool jedisPool = new new JedisPool (poolConfig, IP, Port); 
		
		// Get jedis object from the connection pool 
		jedis jedis jedisPool.getResource = (); 
		
		// operated 
		jedis.set ( "name", "beyond ");
		
		// return connection 
		jedis.close ();
		 
		// close the connection pool 
		jedisPool.close ();
	} 
}

　　

 　　The above demonstrates how the use of Jedis connection pool, but we usually project is almost impossible to do so, we generally will Redis and Spring integration, and configure the connection pool Redis, can refer to
