在Java项目中部署使用Memcached[转]

在项目中使用到Memcached主要的目的是，通过缓存数据库查询结果，减少数据库访问次数，从而提高动态、数据库驱动网站的速度、提高可扩展性。Memcached是一个高性能的分布式内存对象缓存系统，基于一个存储键/值对的hashmap。

实现你的cache类

import net.spy.memcached.MemcachedClient;

import org.apache.commons.logging.Log;

import org.apache.commons.logging.LogFactory;

public final class Memcached implements Cache{

public Object get(String key) {

Object result = null;

try {

result = memcachedClient.get(key);

} catch (Exception e) {

log.error("Failed to get '" + key + "' from cache.", e);

}

return result;

}

public void put(String key, Object value) {

put(key, value, expiredTime);

}

public void put(String key, Object value, int expiredTime) {

try {

memcachedClient.set(key, expiredTime, value);

} catch (Exception e) {

log.error("Failed to put '" + key + "' into cache.", e);

}

}

public void remove(String key) {

try {

memcachedClient.delete(key);

} catch (Exception e) {

log.error("Failed to remove cache '" + key + "'.", e);

}

}

public void setExpiredTime(int expiredTime) {

this.expiredTime = expiredTime;

}

public void setMemcachedClient(MemcachedClient memcachedClient) {

this.memcachedClient = memcachedClient;

}

private MemcachedClient memcachedClient;

private int expiredTime = 60 * 120;

private static final Log log = LogFactory.getLog(Memcached.class);

}

 

在applicationContext里配置cache相关类关系和属性

具体属性的作用可以参考官方说明:https://code.google.com/p/spymemcached/wiki/SpringIntegration
