我正在编写一个webapp,并尝试缓存从控制器调用的一些pojos.
当我尝试使用org.springframework.cache.annotation.Cacheable时,我无法获得任何工作,所以我切换到com.googlecode.ehcaceh.annotations.Cacheable,我仍然无法将其缓存.
我的代码看起来像这样：
@Controller
public class Conttroller {
@RequestMapping(method = RequestMethod.GET)....
public Person getPerson(String id) {
LOG.debug("Trying to get resource...);
Person person = personService.detect(id);
LOG.debug("got person");
并且服务看起来像：
public class PersonService {
@Cacheable(cacheName="deviceCache")
public Person detect(String id) {
LOG.debug("cache missed")
我的applicationContext看起来像
factorybean" p:configLocation="/meta-inf/ehcache.xml" />
我的ehcache看起来像：
disk="false" diskPersistent="false" timetoIdleSeconds="0"
timetoLiveSeconds="600" memoryStoreevictionPolicy="LRU"/>
disk="false" diskPersistent="false"
timetoIdleSeconds="0" timetoLiveSeconds="300"
memoryStoreevictionPolicy="LRU" />
有趣的是它在我的单元测试中缓存…
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:meta-inf/applicationContext-test.xml"})
public class PersonServiceTest {
private static final Logger LOG = LoggerFactory.getLogger(PersonServiceTest.class);
@Test
public void testCache() {
LOG.debug("Getting person...");
Device detect = personService.detect("test");
LOG.debug("Getting person again ...");
detect = personService.detect("test");
LOG.debug("Done");
}
产生：
13:45:02.885 [main] DEBUG PersonServiceTest - Getting person...
13:45:02.887 [main] DEBUG c.g.e.a.i.CacheAttributeSourceImpl - Adding CACHE advised method 'detect' with attribute: CacheableAttributeImpl [cacheInstanceResolver=com.googlecode.ehcache.annotations.resolver.SingletonCacheableCacheResolver@5c2bfdff,cacheKeyGenerator=HashCodeCacheKeyGenerator [includeMethod=true,includeParameterTypes=true,useReflection=false,checkforCycles=false],parameterMask=ParameterMask [mask=[]]]

但我的战争输出(通过tomcat7 / eclipse wtp运行)是：

所以我的问题是,为什么它在我的单元测试中起作用,而不是webapp？我将如何使用spring注释而不是googlecode注释？
最佳答案
您的PersonService服务未实现接口. Ehcache-spring-annotations需要一个接口,如FAQ中所述：
Requirement 1: your class MUST
implement some (any) interface. If your class does not implement an
interface,this project will not be able to create a Proxy to mimic
your class and apply the cache semantics around your annotated
methods.
