首先要在本地安装redis,官方只支持Linux版,windows64版本也有,请自行下载(https://github.com/MSOpenTech/redis/releases

下载完之后测试安装是否成功(http://jingyan.baidu.com/article/f25ef2546119fd482c1b8214.html)若成功后,则开始代码上的测试。

redis的配置文件为:

 

redis.pool.maxActive=1024

redis.pool.maxIdle=200

redis.pool.maxWait=1000

redis.pool.testOnBorrow=false

redis.pool.testOnReturn=true

#IP
redis.ip=127.0.0.1     
#Port
redis.port=6379

 其中,每一个redis服务都会有一个端口,默认为6379端口,IP则表示redis的安装路径IP。

 

 搭建Redis的线程池:

 

public class RedisPoolManager {

    private static JedisPool pool;

    static {
        ResourceBundle bundle = ResourceBundle.getBundle("redis");
        if (bundle == null)
            throw new IllegalArgumentException("[redis.properties] is not found");

        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(Integer.valueOf(bundle.getString("redis.pool.maxActive")));
        config.setMaxIdle(Integer.valueOf(bundle.getString("redis.pool.maxIdle")));
        config.setMaxWaitMillis(Long.valueOf(bundle.getString("redis.pool.maxWait")));
        config.setTestOnBorrow(Boolean.valueOf(bundle.getString("redis.pool.testOnBorrow")));
        config.setTestOnReturn(Boolean.valueOf(bundle.getString("redis.pool.testOnReturn")));

        pool = new JedisPool(config, bundle.getString("redis.ip"), Integer.valueOf(bundle.getString("redis.port")));
    }

    /**
     * Get Jedis resource from the pool
     * @return
     */
    public static Jedis createInstance() {
        Jedis jedis = pool.getResource();
//        jedis.auth("will");
        return jedis;
    }

    /**
     * Return the resource to pool
     * @param jedis
     */
    public static void returnResource(Jedis jedis) {
        pool.returnResource(jedis);
    }

}

jedis基础上实现的自定义,你也可以直接使用jedis)

@Component("cacheManager")
public class CacheManager {

    private volatile static CacheManager uniqueCacheManager;
    private CacheManager(){

    }
    public static CacheManager getInstance(){
        if(uniqueCacheManager == null){
            synchronized (CacheManager.class){
                if(uniqueCacheManager == null){
                    uniqueCacheManager = new CacheManager();
                }
            }
        }
        return uniqueCacheManager;
    }

    private Jedis jedis = RedisPoolManager.createInstance();
