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。
