Java Spring 3.1.1 MVC@Cacheable未被命中

我正在编写一个webapp，并试图缓存一些从控制器调用的pojo

当我尝试使用org.springframework.cache.annotation.Cacheable时，我无法让任何东西正常工作，所以我切换到com.googlecode.ehcaceh.annotations.Cacheable，但仍然无法将其缓存

我的代码如下所示：

@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");

该服务看起来像：

public class PersonService {

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

<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" />

我的应用程序上下文看起来像

<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" />

产生：

但是我的war（通过tomcat7/eclipse wtp运行）的输出是：

所以我的问题是，为什么它在我的单元测试中有效，而不是在webapp中？我如何使用spring注释而不是googlecode注释？

您的

PersonService

服务没有实现接口。Ehcache spring注释需要一个接口，如中所述：

要求1：你的班级必须 实现一些（任何）接口。如果您的类没有实现 接口，此项目将无法创建代理来模拟 您的类并在注释的对象周围应用缓存语义 方法

---

尽管我有一个接口，但我在实现类上有@Cacheable注释。一旦我将它移动到接口类，它就被缓存了。

您需要在spring上下文xml或spring配置文件中启用eh cache注释。比如说

<ehcache:annotation-driven cache-manager="ehCacheManager" />

即使它实现了一个接口，我也有同样的问题自从我使用它已经有一段时间了，但我模糊地记得必须在我的一个缓存的no args方法中添加一个伪方法参数，以便Ehcache可以将缓存的返回值与该方法匹配。值得一试。。。。
