Question

我试图在MYSQL中连接，并且在尝试添加configure next资源时遇到错误：hibernate.cfg.xml。并有下一个错误org.hibernate.MappingNotFoundException：resource：hibernate.cfg.xml not found

的HibernateUtil：

package util;

   Imports

   public class HibernateUtil {
    private static SessionFactory sessionFactory;
    private static ServiceRegistry serviceRegistry;


    static{
        try {
            Configuration configuration = new Configuration();
            configuration.addResource("hibernate.cfg.xml");
            configuration.configure();
            serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
                    configuration.getProperties()).build();
        sessionFactory = configuration.buildSessionFactory(serviceRegistry);
    } catch (HibernateException he) {
        System.err.println("Error creating Session: " + he);
        throw new ExceptionInInitializerError(he);
    }
}

public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
}

hibernate.cfg.xml中：

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <!-- Есть недокументированная возможность none вместо validate, но вроде validate нас устраивает -->
        <property name="hbm2ddl.auto">validate</property>
        <!-- Спросить у преподов, что значит Enables autocommit for JDBC pooled connection -->
        <property name="hibernate.connection.autocommit">false</property>
        <property name="current_session_context_class">thread</property>

        <mapping class="DAO.logic.User" />

    </session-factory>
</hibernate-configuration>

ProjectName.iml（我删除了很多垃圾，导入maven码头等）：

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

尝试将hibernate.cfg.xml放在src/main/resources下。

org.hibernate.MappingNotFoundException：resource：找不到hibernate.cfg.xml
