java - spring mvc integrates hibernate5 access error Could not locate cfg.xml resource

Question

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

Please help to find out what went wrong, Thanks in advance!

Answer 1

Hibernate version 5.2 or above is written like this:

Message message = new Message("Hello,world!");
        Configuration configuration = new Configuration();
        StandardServiceRegistry registry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
        SessionFactory sessionFactory = new MetadataSources(registry).buildMetadata().buildSessionFactory();
        Session session = sessionFactory.openSession();
        Transaction tx = session.beginTransaction();
        session.persist(message);
        tx.commit();
        return "数据添加成功!";

org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [hibernate.cfg.xml] The problem was solved, but org.hibernate.service.spi.ServiceException: Unable to create requested appeared again service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment], also help!

View the web.xml configuration, as follows:

<!-- 加载Spring -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- spring默认的配置文件名称是：applicationContext.xml,如果是默认则不需要配置 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml,
        /WEB-INF/daoContext.xml</param-value>
</context-param>

The data source, sessionFactory, transaction manager, and transactions are configured in daoContext.xml;
Do you add these? See if there are any errors
