Spring MVC menyepadukan rangka kerja Hibernate5—sambungan pangkalan data dan maklumat lain telah dikonfigurasikan dalam fail dispatcher-servlet.xml Saya menulis fungsi mudah untuk membuat jadual data baharu (hanya beberapa fail tidak dilaporkan semasa dijalankan , tetapi org ralat Status HTTP 500 telah dilaporkan semasa mengakses hibernate.internal.util.config.ConfigurationException: Tidak dapat mencari sumber cfg.xml [hibernate.cfg.xml], tetapi pelik bahawa jadual data berjaya dibuat tetapi tiada. data telah ditulis.
Apa yang saya tertanya-tanya ialah sessionFactoryBean akan digunakan dan bukannya fail hibernate.cfg.xml selepas hibernate4 saya tidak mencipta fail hibernate.cfg.xml. Beberapa fail tertentu dan tangkapan skrin ralat adalah seperti berikut
