Spring缓存不能与EHCache + JCache一起使用

Question

I'm trying to integration the ehcache implementation of jcache to work with spring. So I have a facade defined like this:

@Component(value = "sampleFacade")
 @CacheDefaults(cacheName = "default")
 public class SampleFacadeImpl implements SampleFacade
 {

   @Override
   @CacheResult(cacheName = "site")
    public SitePojo getSiteForUid(final String uid)
    {
        System.out.println("getting the site for uid: " + uid);

        final SitePojo pojo = new SitePojo();
        pojo.setUid(uid);
        pojo.setUrl(uid);

        return pojo;
    }
}

and a java based configuration that looks like this:

@Configuration
@EnableCaching(mode = AdviceMode.PROXY)
@ComponentScan(basePackages = { "com.test" })
public class TestConfig implements CachingConfigurer
{
   @Resource
   public ApplicationContext context;

   @Override
   @Bean(name = { "defaultKeyGenerator", "keyGenerator" })
   public KeyGenerator keyGenerator() {
       return new SimpleKeyGenerator();
   }

   @Override
   @Bean(name = { "defaultCacheManager", "cacheManager" })
   public CacheManager cacheManager() {
       final JCacheCacheManager cacheManager = new JCacheCacheManager();
       cacheManager.setCacheManager((javax.cache.CacheManager) context.getBean("cacheManagerFactoryBean"));

       return cacheManager;
   }

   @Bean(name = { "defaultCacheManagerFactoryBean", "cacheManagerFactoryBean" })
   protected JCacheManagerFactoryBean defaultCacheManagerFactoryBean() {
       return new JCacheManagerFactoryBean();
   }
}

and a test that calls the facade 10 times:

@Test
public void testGetSiteForUid() {
    for (int i = 0; i < 10; i++) {
        assertNotNull(sampleFacade.getSiteForUid("uid"));
    }
}

but the result is passing through the method 10 times:

getting the site for uid: uid
getting the site for uid: uid
getting the site for uid: uid
getting the site for uid: uid
getting the site for uid: uid
getting the site for uid: uid
getting the site for uid: uid
getting the site for uid: uid
getting the site for uid: uid
getting the site for uid: uid

You can find a sample project to reproduce it here: https://github.com/paranoiabla/spring-cache-test

JCache support is a new feature of Spring 4.1. You are using 4.0.4 which does not have this support yet.

Spring Framework 4.1 has not been released yet. You can try a snapshot by adding the following to your project

<repositories>
  <repository>
    <id>spring-snapshot</id>
    <name>Springframework Snapshot Repository</name>
    <url>http://repo.spring.io/snapshot</url>
    <snapshots>
      <enabled>true</enabled>
    </snapshots>
  </repository>
</repositories>

And flip the spring.version to 4.1.0.BUILD-SNAPSHOT

I have forked your project and updated it here so that it works as it should. Checking what I've changed would help you understand what was missing.

NOTE: your JSR-107 cache manager is wrong. You should create a javax.cache.CacheManager and once you have it you should wrap it to a Spring's CacheManager . Keep in mind you could just as well declare any CacheManager there and it would work ( SimpleCacheManager , GuavaCacheManager , etc).
