java - spring mvc integrates hibernate5 access error Could not locate cfg.xml resource
Spring MVC integrates the Hibernate5 framework—the database connection and other information has been configured in the dispatcher-servlet.xml file. I wrote a simple function to create a new data table (just a few files). No error is reported when running, but HTTP Status 500 error is reported when accessing. org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [hibernate.cfg.xml], but it is strange that the data table was successfully created but no data was written.
What I am very confused about is that after hibernate4, sessionFactoryBean is not used to replace the hibernate.cfg.xml file. I did not create the hibernate.cfg.xml file. Some specific files and error screenshots are as follows
