java - Hibernate - 无法加载请求的类 : org. mariadb.jdbc.Driver

Question

所以我的问题非常基本。我只是运行一个简单的 hibernate Web 应用程序，它将一个新条目发送到我的 SQL MariaDB。当我运行该应用程序时，我收到一条错误消息，指出无法加载请求的类。没有意义的是我的库中有 .jar 文件，而我的其他测试文件运行良好。对于这个项目，我使用 Intellij IDEA。

hibernate.cfg.xml

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

<hibernate-configuration>

<session-factory>

    <!-- JDBC Database connection settings -->
    <property name="connection.driver_class">com.mariadb.jdbc.Driver</property>
    <property name="connection.url">jdbc:mariadb://localhost:3306/hb_student_tracker</property>
    <property name="connection.username">hbstudent</property>
    <property name="connection.password"></property>

    <!-- JDBC connection pool settings ... using built-in test pool -->
    <property name="connection.pool_size">1</property>

    <!-- Select our SQL dialect -->
    <property name="dialect">org.hibernate.dialect.MariaDB53Dialect</property>

    <!-- Echo the SQL to stdout -->
    <property name="show_sql">true</property>

    <!-- Set the current session context -->
    <property name="current_session_context_class">thread</property>

</session-factory>

创建学生演示

import com.luv2code.hibernate.demo.entity.Student;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class CreateStudentDemo {

public static void main(String[] args) {

    //create session factory
    SessionFactory factory = new Configuration()
                             .configure("hibernate.cfg.xml")
                             .addAnnotatedClass(Student.class)
                             .buildSessionFactory();
    // create session
    Session session = factory.getCurrentSession();

    try {
        // create a student object
        System.out.println("Creating new student object...");
        Student tempStudent = new Student(
                              "Paul", "Wall", "paul@luv2code.com");

        // start a transaction
        session.beginTransaction();

        // save the student object
        System.out.println("Saving the student...");
        session.save(tempStudent);

        // commit transaction
        session.getTransaction().commit();

        System.out.println("Done!");
    }
    finally {
        factory.close();
    }
}

我认为问题出在 hibernate.xml 文件上。任何帮助将不胜感激!
