初识redis

现在NoSQL已经火的不能再火了，听了这么长时间，今天才试了一下。

 

java驱动用的是jedis 2.0.0，可以到这下：http://mvnrepository.com/artifact/redis.clients/jedis

 

刚开始写了个入门级程序插入redis，每秒才900条左右，不仅让我大喊坑爹，但是一想，

 

额····是单线程····

 

起了10个线程后，到每秒到9000条了。

 

现贴出代码：

 

package com.test;

import redis.clients.jedis.*;

public class RedisTest {

	private static JedisPool pool;

	static {
		JedisPoolConfig config = new JedisPoolConfig();
		config.setMaxActive(100);
		config.setMaxIdle(20);
		config.setMaxWait(1000);
		config.setTestOnBorrow(true);
		pool = new JedisPool(config, "10.10.67.9");
	}

	public static void main(String[] args) {
		RedisTest demo = new RedisTest();
		demo.test();
	}

	public void test() {
		testThread();
		// initInsert();
//		 flush();
		// getData(1000000);
	}

	private void initInsert() {
		System.out.println("RedisTest 插入数据开始");
		Jedis jedis = (Jedis) pool.getResource();
		for (long i = 0; i <= 1000000; i++) {
			jedis.set(EhcacheTest.long2Ip(i), "cmcc");
		}
		pool.returnResource(jedis);
		System.out.println("RedisTest 插入数据结束");
	}

	private void getData(long key) {
		Jedis jedis = (Jedis) pool.getResource();
		long time = System.currentTimeMillis();
		System.out.println(jedis.get(EhcacheTest.long2Ip(key)));
		System.out.println(System.currentTimeMillis() - time);

		System.out.println(jedis.dbSize());
	}

	private void flush() {
		Jedis jedis = (Jedis) pool.getResource();
		jedis.flushAll();
	}

	private void testThread() {
		Thread thread[] = new Thread[10];
		for (int i = 0; i < thread.length; i++) {
			thread[i] = new MyThread();
			thread[i].setName(String.valueOf(i));
			thread[i].start();
		}
	}

	class MyThread extends Thread {
		@Override
		public void run() {
			int num = Integer.parseInt(this.getName()) * 100000;
			
			Jedis jedis = RedisTest.pool.getResource();
			for (int i = num; i < num + 100000; i++) {
				jedis.set(EhcacheTest.long2Ip(i), "cmcc");
			}
		}
	}
}
