在應用程序中使用了二級緩存，但是未給定hibernate.cache.region.factory_class屬性JPA + hibernate + Spring

Question

嗨，這個問題已經被問了很多遍了，但是在我的應用程序中二級緩存仍然無法配置。 我正在使用JPA + hibernate + Spring，我嘗試了可能的配置方法，但未成功。

這些是用於配置的鏈接

如何使用Hibernate 3.5.2配置JPA 2.0以將EHCache用作2級緩存和查詢緩存？

這是我的錯誤

 Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext-persistence.xml]: 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.

用於緩存的類

import org.hibernate.annotations.Cache;
 import org.hibernate.annotations.CacheConcurrencyStrategy;
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE, region = "categories")
public class Category implements Serializable {

    private static final long serialVersionUID = 1L;
    private static final Log LOG = LogFactory.getLog(Category.class);

    @Id
    @Column(name = "CATEGORY_ID")
    @GeneratedValue(generator = "CategoryId")
    @GenericGenerator(name = "CategoryId", strategy = "com.ornamentbazzar.common.util.CustomTableGenerator", parameters = {

這條線斷了

    <property name="persistenceXmlLocation" value="classpath:* META-INF/persistence.xml" />

*看起來很虛假。 或看起來像是classpath*:它將合並您在類路徑上找到的所有persistence.xml ，包括JAR，盡管我不確定您為什么要這么做。

該行還引用了persistence.xml ，即使您的問題使用了persistent.xml 。 因此，首先要進行檢查。
