[SPRING] GWT Dev 모드 + Spring 3.1 + Hibernate 4.0.1의 예외

GWT Dev 모드 + Spring 3.1 + Hibernate 4.0.1의 예외

나는 Spring 3.0.x + Hibernate 3.6.x에서 OK 인 GWT + Hibernate + JPA + Spring 설정 파일을 가지고있다. Spring 3.1과 Hibernate 4.0으로 업그레이드했을 때, 다음과 같은 예외가 발생합니다 :

Hibernate 4와 Spring 3.1에 알려진 호환성이 있습니까?

해결법

1. ==============================

   1.이 문제는 Hibernate 4.1.4에서 수정되었다.

   이 문제는 Hibernate 4.1.4에서 수정되었다.

   나는 같은 문제가 있었고, Jetty 클래스 로더 (GWT 플러그인은 호스트 모드 용으로 Jetty를 사용함), GWT 플러그인 및 Hibernate와 관련이있는 것으로 보입니다 (물론 다른 라이브러리와 마찬가지로).

   그것은 Hibernate Bug Report에서 언급 된 버그와 비슷하지만 우리의 경우 GWT 플러그인을 통해 실행 중이며 ConnectionProvider에 ClassCastException이 발생합니다.

   버그 보고서에 언급 된 수정 사항으로 인해 특정 문제가 해결됩니다.

   org.hibernate.service.classloading.internalClassLoaderServiceImpl의 경우 생성자를 통해 부모를 null로 설정합니다.

   this.classClassLoader = new ClassLoader(null) {
           @Override
           protected Class<?> findClass(String name) throws ClassNotFoundException {
               for ( ClassLoader loader : classLoadingClassLoaders ) {
                   try {
                       return loader.loadClass( name );
                   }
                   catch (Exception ignore) {
                   }
               }
               throw new ClassNotFoundException( "Could not load requested class : " + name );
           }
   };
   

2. ==============================

   2.이미있는 경우 / lib 디렉토리에서 ejb3-persistence.jar을 제거하십시오. 그것은 hibernate-jpa-2.0-api-1.0.1.Final.jar과 충돌한다. 이것은이 문제를 가지고 나에게 도움이되었는데, 나는 Ghost, Ghost, Hibernate 4, Spring 3.1.1을 Openshift 환경 https에 호스트했다. : //openshift.redhat.com/app/

3. ==============================

   3.persistence.xml에서 org.hibernate.ejb.HibernatePersistence 를 설정할 필요가 없다고 생각합니다. 문서를 확인하십시오.
