Java Spring缓存不与EHCache+；JCache

我正在尝试将jcache的ehcache实现集成到spring中。所以我有一个定义如下的外观：

@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;
    }
}

@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();
   }
}

基于java的配置如下所示：

@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;
    }
}

@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();
   }
}

以及调用facade 10次的测试：

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

您可以在此处找到一个示例项目来复制它：

JCache支持是Spring 4.1的一项新功能。您使用的是4.0.4，它还没有这种支持

SpringFramework 4.1尚未发布。您可以通过将以下内容添加到项目中来尝试快照

<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>

春季快照
Springframework快照存储库
http://repo.spring.io/snapshot
真的

然后将

spring.version

翻转到

4.1.0.BUILD-SNAPSHOT

我已经对你的项目进行了分叉并进行了更新，使其能够正常工作。有助于你理解遗漏了什么

注意：您的JSR-107缓存管理器是错误的。您应该创建一个

javax.cache.CacheManager

，一旦有了它，就应该将它包装到Spring的

CacheManager

。请记住，您也可以在那里声明any

CacheManager

，它会工作（

SimpleCacheManager

，

GuavacheManager

，等等）。

您好，我尝试了您的建议，它显示了以下错误：java.lang.IllegalArgumentException:找不到CacheResultOperation的名为“site”的缓存[详细信息][method=public com.test.cache.SitePojo com.test.cache.impl.SampleFacadeImpl.getCurrentSite（），cacheAnnotation=@javax.cache.annotation.CacheResult（cacheKeyGenerator=interface javax.cache.annotation.cacheResolverFactory，cachedExceptions=[]，skipGet=false，exceptionCacheName=，cacheName=site，nonCachedExceptions=[]），cacheName='site']]嗨，我尝试了你的建议，它显示了这个错误：嗨，我尝试了你的建议，它显示了这个错误：我在你的scratch应用程序中看到你像这样使用SimpleCacheManager:SimpleCacheManager manager=new SimpleCacheManager（）；manager.setCaches（asList（新ConcurrentMapCache（“默认”），新ConcurrentMapCache（“另一”））；return manager；但不幸的是，JCacheCacheCacheManager没有setCaches方法。如何为我的JCacheCacheManager指定缓存？我认为您应该重新访问

ehcache jcache

以及如何配置它。创建另一个线程可能是个好主意，因为这与Spring无关（这是一个纯粹的JSR-107 ehcache问题）。与此同时，您可以直接使用纯ehcache或查看我的fork（我编辑了我的原始答案）
