Memcached 配置

目前系统中 Memcatch

 

    <!-- 缓存 -->

                factory-method="build" destroy-method="shutdown"/>
      

 

 

使用SPRING 管理的 。 。

 

引用JAR包 ：

 

Maven 配置　：　

 

        <dependency>
            <groupId>com.googlecode.xmemcached</groupId>
            <artifactId>xmemcached</artifactId>
        </dependency>

 

使用的Ｊａｖａ代码：

 

 

	private Brand getBrandById(long brandId){
		Brand brandres=null;
		String key="brand_cacheD_"+brandId;
		MemcachedClient memcachedClient=(MemcachedClient) SpringBeanProxy.getBean("memcachedClient");
		try {
			Object object=memcachedClient.get(key);
			if(object!=null){
				brandres=(Brand)object;
				log.debug(" memcached get Brand ");
			}else{
				BrandDao brandDao=(BrandDao)SpringBeanProxy.getBean("brandDao");
				brandres=brandDao.getById(brandId);
				memcachedClient.set(key, 30*60*1000, brandres);
				log.debug(" db get Brand ");
			}
		} catch (TimeoutException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (MemcachedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	
		return brandres;
	}
	

 

可见，  基本就是像使用一个 HASHMAP 一样的来使用 。 。。
