Ngoại lệ trong GWT Dev Mode + Mùa xuân 3.1 + Hibernate 4.0.1

Question

Tôi có tệp cấu hình GWT + Hibernate + JPA + Spring OK với Spring 3.0.x + Hibernate 3.6.x. Khi tôi nâng cấp lên Spring 3.1 và Hibernate 4.0, ngoại lệ sau đây được ném:

Có bất kỳ sự không tương thích nào đã biết với Hibernate 4 và Spring 3.1 không?

Dưới đây là một phần của ứng dụng context.xml cấu hình của tôi:

Answer 1

Sự cố này được khắc phục in Hibernate 4.1.4.

---

tôi đã cùng một vấn đề, và có vẻ như có liên quan đến các classloader Jetty (plugin GWT sử dụng Jetty cho chế độ lưu trữ), plugin GWT và Hibernate (mặc dù nó có vẻ cây trồng lên với các thư viện khác cũng).

Nó tương tự như lỗi được đề cập ở đây Hibernate Bug Report nhưng trong trường hợp của chúng tôi, chúng tôi đang chạy nó thông qua plugin GWT và nó gây ra một ClassCastException cho ConnectionProvider.

Sửa chữa được đề cập trong báo cáo lỗi nên khắc phục sự cố cụ thể đó.

Đối org.hibernate.service.classloading.internalClassLoaderServiceImpl thiết phụ huynh để null qua các nhà xây dựng:

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); 
     } 
}; 

Answer 2

Tôi nghĩ rằng bạn không cần phải thiết lập <provider>org.hibernate.ejb.HibernatePersistence</provider> trong persistence.xml. Kiểm tra the docs.

Answer 3

xóa ejb3-persistence.jar trong thư mục/lib nếu đã có; nó xung đột với hibernate-jpa-2.0-api-1.0.1.Final.jar trong hibernate 4. Điều đó làm việc cho tôi sau khi có vấn đề này, tôi đã đạt được để lưu trữ một ứng dụng GWT, Hibernate 4, Spring 3.1.1 trên môi trường Openshift https://openshift.redhat.com/app/
