私は webapp を作成しており、コントローラーから呼び出されるいくつかの pojo をキャッシュしようとしています。

org.springframework.cache.annotation.Cacheable を使ってみたところうまくいかなかったので、com.googlecode.ehcaceh.annotations.Cacheable に切り替えましたが、いまだにキャッシュできません。

私のコードは次のようになります。

@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");

サービスは次のようになります。

public class PersonService {

@Cacheable(cacheName="deviceCache") 
public Person detect(String id) {
LOG.debug("cache missed")

私のapplicationContextは次のようになります

<context:component-scan base-package="com.mycompany" />


         <ehcache:annotation-driven cache-manager="ehCacheManager" />
         <bean id="cacheManager"      class="org.springframework.cache.ehcache.EhCacheCacheManager">
            <property name="cacheManager">
                <ref bean="ehCacheManager" />
            </property>
        </bean>
        <bean id="ehCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" p:configLocation="/META-INF/ehcache.xml" />

そして私のehcacheは次のようになります：

<defaultCache eternal="false" maxElementsInMemory="1000"
    overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"
    timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU"/>

<cache name="deviceCache"
    maxElementsInMemory="100" overflowToDisk="false" diskPersistent="false"
    timeToIdleSeconds="0" timeToLiveSeconds="300"
    memoryStoreEvictionPolicy="LRU" />

興味深いのは、単体テストで問題なくキャッシュされることです...

@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");
}

これは以下を生成します:

    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=[]]]

しかし、私の戦争の出力（tomcat7/eclipse wtpを介して実行）は次のとおりです。

だから私の質問は、なぜそれが私の単体テストで動作し、webapp で動作しないのですか? また、googlecode アノテーションの代わりに spring アノテーションを使用するにはどうすればよいですか?

あなたのPersonServiceサービスはインターフェースを実装していません。FAQで説明されているように、Ehcache-spring-annotations にはインターフェースが必要です。

要件 1: クラスは何らかの (任意の) インターフェイスを実装する必要があります。クラスがインターフェイスを実装していない場合、このプロジェクトはプロキシを作成してクラスを模倣し、注釈付きメソッドにキャッシュ セマンティクスを適用することができません。
