java – Hibernate中的错误简单示例初学者级别

Failed to create sessionFactory object.java.lang.NoClassDefFoundError:
javax/transaction/SystemException Exception in thread “main”
java.lang.ExceptionInInitializerError Caused by:

com.example.ManageEmployee.main(ManageEmployee.java:17)

基本上,我首先编写POJO,并使用eclipse生成hbm.xml.之后,我编写了管理数据库的主要功能.我试了两次,但遇到了同样的问题.

有人可以给我建议解决这个问题吗？在此之前,使用JDBC构建项目,但这太复杂了.所以我需要学习hibernate.谢谢.

补充(此hibernate示例项目中的详细信息)：

>我的Eclipse项目名称：HibernateExa
> hibernate.cfg.xml：

<session-factory>

    <!-- hibernate dialect -->

    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.password">hibernateTest</property>

    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernatetest;</property>
    <property name="hibernate.connection.username">hibernater</property>
    <property name="hibernate.default_schema">hibernatetest</property>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

    <!-- Automatic schema creation(begin) -->
    <property name="hibernate.hbm2ddl.auto">create</property>
    <!-- Simple memory-only cache -->
    <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
    <!-- Enable Hibernate's automatic session context management -->
    <property name="current_session_context_class">thread</property>

    <!-- mapping files with external dependencies -->
    <mapping resource="com/sample/Person.hbm.xml"/>


</session-factory>

>我的POJO是Person.java.使用eclipse生成Person.hbm.xml.
> Project包含main函数：TestPerson.java

public static void main(String [] args){

    Session session = SessionFactoryUtil.getSessionFactory().getCurrentSession();

    session.beginTransaction();

    createPerson(session);
    queryPerson(session);

}

public static void createPerson(Session session){
    Person person = new Person();

    person.setName("Jack");
    person.setSurname("Yu");
    person.setAddress("White House");

    session.save(person);
}

private static void queryPerson(Session session){
    Query query = session.createQuery("from person");
    List<Person> list = new ArrayList<Person>();
    list = query.list();
    java.util.Iterator<Person> iter = list.iterator();

    while(iter.hasNext()){
        Person person = iter.next();
        System.out.println("Person: "" + person.getName() + "","+ person.getSurname() + "","
                + person.getAddress());
    }

    session.getTransaction().commit();
}
