ehcache缓存原理_ehcache使用_ehcache memcache 区别(4)

删除cache

CacheManager singletonManager = CacheManager.create();

singletonManager.removeCache("sampleCache1");

在使用ehcache后，需要关闭

CacheManager.getInstance().shutdown()

caches 的使用

Cache cache = manager.getCache("sampleCache1");

执行crud操作

Cache cache = manager.getCache("sampleCache1");

Element element = new Element("key1", "value1");

cache.put(element);

update

Cache cache = manager.getCache("sampleCache1");

cache.put(new Element("key1", "value1");

//This updates the entry for "key1"

cache.put(new Element("key1", "value2");

get Serializable

Cache cache = manager.getCache("sampleCache1");

Element element = cache.get("key1");

Serializable value = element.getValue();

get non serializable

Cache cache = manager.getCache("sampleCache1");

Element element = cache.get("key1");

Object value = element.getObjectValue();

remove

Cache cache = manager.getCache("sampleCache1");

Element element = new Element("key1", "value1"

cache.remove("key1");

7.EhCache在S2SH的用法

1，下载EhCache web版 注意下载web版。可见附件

2，解压 将ehcache-web-2.0.3.jar 、ehcache-core-2.3.0.jar 拷入lib中。

3，在src下建立ehcache.xml

4，开始配置 web.xml ,注意此filter配置应该放在Struts2核心filter的前面。

<!-- 页面缓存配置 ehcache -->
	<filter>
		<filter-name>SimplePageFragmentCachingFilter</filter-name>
		<filter-class>net.sf.ehcache.constructs.web.filter.SimplePageFragmentCachingFilter</filter-class>
		<init-param>
			<param-name>suppressStackTrace</param-name>
			<param-value>false</param-value>
		</init-param>
		<init-param>
			<param-name>cacheName</param-name>
			<param-value>SimplePageFragmentCachingFilter</param-value>
		</init-param>
	</filter>

	<filter-mapping>
		<filter-name>SimplePageFragmentCachingFilter</filter-name>
		<url-pattern>/index.action</url-pattern>
	</filter-mapping>
