EHCache配置+Spring Boot：NoCacheRegionFactoryAvailableException

我正在尝试配置基于EHCache的Spring Boot应用程序的二级缓存。

我遇到了以下异常：

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.

这是我的配置：

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;
    }
}

我的实体：

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

ehcache.xml:

<?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>

这是什么原因导致的？
Spring缓存和Hibernate二级缓存是不同的东西... - M. Deinum
EHCache被用作Hibernate的二级缓存，在我的情况下，我正在使用Spring Data JPA（与Hibernate一起）。那么我的困惑在哪里呢？ - Tal Etinger
如所述，Spring的缓存抽象和在JPA提供程序中使用二级缓存是没有任何关系的。基本上，你为Spring Caching设置并没有做任何事情，或者至少与你遇到的错误没有关系。 - M. Deinum
在这里（http://www.ehcache.org/documentation/2.8/integrations/hibernate），您可以找到有关`EhCache`和Hibernate 3.3 / 4.x的一些有用细节。它还显示了hibernate.cache.region.factory_class的值。 - ROMANIA_engineer
在我的情况下，我忘记在grails-app/conf/（Grails 3）中创建我的application.yml文件。 - Eduardo Cuomo

错误信息的关键部分是：

应用程序中使用了二级缓存，但未给出属性hibernate.cache.region.factory_class；请禁用二级缓存或设置正确的区域工厂使用hibernate.cache.region.factory_class设置，并确保在类路径上可用二级缓存提供程序（如hibernate-infinispan）

您可以在Spring Boot的application.properties文件中设置factory_class属性。例如：

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

您需要使用的类名将取决于您的EhCache依赖项；在此示例中，我使用了hibernate-ehcache。

我遇到了同样的问题，但是使用=代替:，结果不起作用。为什么属性格式不同呢？抱歉这不是这里应该问的问题，但是感谢你让我找到了我的问题所在（并被这个问题困扰）。 - HankCa

您可以在属性文件中使用=或:来分隔键和值。 - Andy Wilkinson
是的，这就是我想的。我再试了一遍，现在可以了。之前可能复制进来了一个奇怪的字符。现在一切都好了！ - HankCa
