EHCache設定+春のブート：NoCacheRegionFactoryAvailableException

Question

私はEHCacheに基づいて2次キャッシュでSpringブートアプリケーションを設定しようとしています。私はこの例外を取得してい ：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method  failed; nested exception is org.hibernate.cache.NoCacheRegionFactoryAvailableException: Second-level cache is used in the application, but property hibernate.cache.region.factory_class is not given; please either disable second level cache or set correct region factory using the  hibernate.cache.region.factory_class setting and make sure the second level cache provider (hibernate-infinispan, e.g.) is available on the classpath.

は、これは私の設定です：

Application.class：

@EnableAutoConfiguration 
@Configuration 
@ComponentScan 
@ImportResource(value = "/ws.xml") 
public class Application { 

    public static void main(String[] args) throws Exception { 
     SpringApplication.run(Application.class, args); 
    } 
} 

CacheConfig.class：

@Configuration 
@EnableCaching 
public class CachingConfig implements CachingConfigurer { 

    @Bean 
    @Override 
    public CacheManager cacheManager() { 
     EhCacheCacheManager cacheManager = new EhCacheCacheManager(); 
     cacheManager.setCacheManager(ehCacheManagerFactoryBean().getObject()); 
     return cacheManager; 
    } 

    @Bean 
    @Override 
    public KeyGenerator keyGenerator() { 
     return new SimpleKeyGenerator(); 
    } 

    @Bean 
    public EhCacheManagerFactoryBean ehCacheManagerFactoryBean() { 
     EhCacheManagerFactoryBean ehCacheManagerFactoryBean = new EhCacheManagerFactoryBean(); 
     ehCacheManagerFactoryBean.setConfigLocation(new ClassPathResource("ehcache.xml")); 
     ehCacheManagerFactoryBean.setCacheManagerName("messageCache"); 
     ehCacheManagerFactoryBean.setShared(true); 
     return ehCacheManagerFactoryBean; 
    } 
} 

MyEntity：

@Entity 
@XmlRootElement 
@Table(name = "my_entity") 
@Cacheable(value = true) 
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY) 
public class MyEntity { ... } 

ehcache.xml：これを引き起こしている何

<?xml version="1.0" encoding="UTF-8"?> 
<ehcache> 
    <defaultCache eternal="true" maxElementsInMemory="100" overflowToDisk="false" /> 
    <cache name="messageCache" maxElementsInMemory="10" eternal="true" overflowToDisk="false" /> 
</ehcache> 

？

エラーメッセージの重要な部分である：

第2レベル・キャッシュはアプリケーションで使用されるが、プロパティhibernate.cache.region.factory_classが与えられていません。あなたは春ブーツの中factory_classプロパティを設定することができ、クラスパス

で提供されています（休止状態-infinispan、例えば）hibernate.cache.region.factory_class設定を使用して、第2レベルのキャッシュや設定が正しい地域の工場を無効にして、二次キャッシュ・プロバイダーを確認してどちらかしてくださいすることapplication.propertiesファイル。例：

spring.jpa.properties.hibernate.cache.region.factory_class: org.hibernate.cache.ehcache.EhCacheRegionFactory 

使用する必要があるクラス名は、EhCacheの依存関係によって異なります。この場合、私はhibernate-ehcacheを使用しました。
