spring 3.2.4配置注解ehcache

配置ehcache,ehcache.xml内容如下:

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:noNamespaceSchemaLocation="ehcache.xsd">

	<defaultCache maxElementsInMemory="10000" eternal="false"
		timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="false"
		diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000"
		diskPersistent="false" diskExpiryThreadIntervalSeconds="120"
		memoryStoreEvictionPolicy="LRU" />

	<cache name="userCache" maxElementsInMemory="1000" eternal="false"
		timeToIdleSeconds="100000" timeToLiveSeconds="100000" overflowToDisk="false" />
		
</ehcache>

配置spring管理ehcache:

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:cache="http://www.springframework.org/schema/cache"
	xsi:schemaLocation="
			http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
			http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.1.xsd">

	<!--启用缓存注解功能,这个是必须的,否则注解不会生效,另外,该注解一定要声明在spring主配置文件中才会生效-->
	<cache:annotation-driven cache-manager="cacheManager" />

	<!-- cacheManager工厂类,指定ehcache.xml的位置 -->
	<bean id="cacheManagerFactory"
		class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"
		p:configLocation="classpath:ehcache.xml" />

	<!-- 声明cacheManager -->
	<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager"
		p:cacheManager-ref="cacheManagerFactory" />
</beans>
public class EhcacheSpringTest {

	private CacheManager cacheManager;
	
	private Cache cache;

	@Before
	public void init() {
		ApplicationContext ctx = new ClassPathXmlApplicationContext(
				"applicationContext.xml");
		EhCacheCacheManager ehCacheManager = (EhCacheCacheManager) ctx
				.getBean("cacheManager");
		cacheManager = ehCacheManager.getCacheManager();
		cache = cacheManager.getCache("userCache");
	}
	
	@After
	public void destory() {
		cacheManager.shutdown();
	}

	@Test
	public void testEhcacheString() {
		String key = "hello";
		String value = "world";
		cache.put(new Element(key, value));
		Element element = cache.get(key);
		Object obj = element.getObjectValue();
		Assert.assertEquals(value, obj);
		System.out.println(obj);
	}

	@Test
	public void testEhcacheObj() {
		String key = "user";
		User value = new User("zhangsan", "lisi");
		cache.put(new Element(key, value));
		Element element = cache.get(key);
		Object obj = element.getObjectValue();
		Assert.assertEquals(value, obj);
		System.out.println(obj);
		Object objSer = element.getValue();
		Assert.assertEquals(value, objSer);
		System.out.println(objSer);
	}
}

重点在上面配置里的那句,【缓存配置一定要声明在spring主配置文件中才会生效】搞了我一晚上。

现在只是写来总结一下。
