Pertanyaan hibernate-c3p0 tidak terlihat oleh classloader modul hibernate


Saya mengalami masalah yang sangat aneh dengan aplikasi spring / hibernate / c3p0 / jboss saya. Saat mulai, log ditampilkan

16: 42: 09.219 INFO [org.hibernate.service.jdbc.connections.internal.ConnectionProviderInitiator] (MSC service thread 1-4) HHH000130: Instansiasi penyedia koneksi eksplisit: org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider

Namun, ada sedikit cara untuk mencoba menciptakan kacang SessionFactory, saya mengerti

diikuti oleh tumpukan jejak yang spektakuler yang diakhiri dengan

Disebabkan oleh: java.lang.ClassNotFoundException: Tidak dapat memuat kelas yang diminta: org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider

Saya dapat melihat baik hibernate-c3p0-4.0.1.Final.jar dan c3p0-0.9.1.jar di direktori deploy, mereka pasti disertakan. Saya bahkan membuka hibernate-c3p0-4.0.1.Final.jar untuk memastikan kelas benar-benar ada di sana, dan tepat di mana seharusnya.

Saya telah melangkah melalui ini di debugger. Pertama kali, kelas berhasil dimuat oleh ModuleClassLoader untuk deployment.tdm-web-proof-of-concept.war: main. Kali kedua, ModuleClassLoader untuk org.hibernate: main mencoba dan gagal menemukannya. Saya yakin ini adalah semacam masalah konfigurasi di mana classloader modul hibernate tidak bisa melihat ini. Ada gagasan bagaimana saya bisa mengarahkannya ke arah yang benar?

Jawaban:


Ada bug di versi ini org.springframework.orm.hibernate4.LocalSessionFactoryBuilder.buildSessionFactory(). Ini salah mengasumsikan bahwa metode usang dalam kelas hibernate itu mewarisi dari akan memuat baik classloader yang memuatnya dan TCCL, yang merupakan detail implementasi. Sebaliknya, metode ini hanya menggunakan classloader yang memuatnya, classloader modul hibernate. Classloader ini tidak memiliki kelas penyebaran di classpath-nya, sehingga membuang ClassNotFoundException.

Dari ini, kita dapat mengatakan bahwa org.springframework.orm.hibernate4.LocalSessionFactoryBean dalam versi musim semi ini tidak dapat digunakan dengan versi hibernasi 4 ini.

Dari http://www.mkyong.com/hibernate/hibernate-could-not-find-c3p0connectionprovider/ :

Ini agak lama, saya akan mengatakan pra-AS 7, tetapi mungkin berlaku juga. Tentu saja Anda harus mencocokkan versi dengan Hibernate yang termasuk dalam AS.


Sejak Hibernate v3.3 (jika tidak salah), "C3P0ConnectionProvider" dipindahkan ke file jar lain "hibernate-c3p0.jar". Anda perlu memasukkannya, untuk membuat Hibernate mendukung koneksi c3p0.

Anda dapat mengunduh "hibernate-c3p0.jar" dari repositori publik JBoss.
