Question

hibernate.cfg.xml是：

＆＃13;

<?xml version="1.0" encoding="utf-8"?>
<!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>
        <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
        <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/testdb</property>
        <property name="hibernate.connection.username">postgres</property>
        <property name="hibernate.connection.password">sql123</property>
        <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
        <property name="show_sql">true</property>
        <property name="format_sql">true</property>
        <property name="hbm2ddl.auto">create </property>
        <mapping resource="/com/eql/model/Employee.hbn.xml" />
    </session-factory>
</hibernate-configuration>

＆＃13;

方法是：

public void addEmployee(Employee employee) {
    try {
     Configuration configuration = new Configuration();
     configuration.configure("${pageContext.request.contextPath}/hibernate.cfg.xml");

     SessionFactory sessionFactory=configuration.buildSessionFactory();
     Session session=sessionFactory.openSession();
     Transaction transaction =session.beginTransaction();
     session.save(employee);
     transaction.commit();

     System.out.println("\n\n Details Added");
    }
    catch(HibernateException e) {
         System.out.println(e.getMessage());
         System.out.println("error");
    }
}

Stack跟踪是：

我添加了所有必需的hibernate jar，我尝试了很多方法

 Configuration configuration = new Configuration();
     configuration.configure("${pageContext.request.contextPath}/hibernate.cfg.xml");

我写了hibernate.cfg.xml的完整路径。
我只写了hibernate.cfg.xml

有谁可以告诉我，我在这个项目中做错了什么？

提前谢谢
