Tôi đang triển khai ứng dụng Hibernate (v 4.1.5.SP1, validator 4.3.0.Final) (một Jar file) chạy trên một MySQL 5.5 db đến JBoss 4.2.3.GA (không thể thay đổi điều này). Tôi nhận được lỗi "org.hibernate.cache.NoCachingEnabledException: Bộ nhớ cache cấp hai không được bật để sử dụng" khi chạy ứng dụng, nhưng có vẻ như tôi đã định cấu hình đúng mọi thứ. Tôi đang sử dụng những phụ thuộc Maven ...Sự cố khi định cấu hình bộ nhớ cache Hibernate - org.hibernate.cache.NoCachingEnabledException: Bộ nhớ cache cấp thứ hai không được bật để sử dụng
<!-- Hibernate dependencies -->
<dependency>

</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-ehcache</artifactId>
<version>${hibernate.version}</version>
</dependency>
Các lỗi là số lẻ bởi vì tôi có bộ nhớ cache được cấu hình trong file hibernate.cfg.xml tôi ...

này được bao gồm trong tôi META-INF/tập tin persistence.xml, đó là bên dưới ...

</properties>
</persistence-unit>
</persistence>
Để ghi đè classloaders JBoss, tôi bao gồm tập tin này tại META-INF/jboss.xml ...
<jboss>
<class-loading java2ClassLoadingCompliance="false">
<!-- setup classLoader repository. java2ParentDelegation to always have
package libs override server libs for this application -->
<loader-repository>
org.mainco.subco.orgs:loader=orgsclient
<loader-repository-config>
java2ParentDelegation=false
</loader-repository-config>
</loader-repository>
</class-loading>
</jboss>
Đây là dấu vết ngăn xếp hoàn chỉnh. Nguyên nhân của việc này là gì?

Cảm ơn, - Dave
là 'hibernate.cache.provider_class 'được định nghĩa là' org.hibernate.cache.EhCacheProvider'? – SiB
