在用Hibernate时遇到了问题
Student.javapackage test;
public class Student {
private int id;
private String name;
private int age;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
StudentTest.java
package test;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class StudentTest {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Student st = new Student();
st.setId(1);
st.setName("yuhao");
st.setAge(23);
Configuration cfg = new Configuration();
SessionFactory sf = cfg.configure().buildSessionFactory();
Session ss = sf.openSession();
ss.beginTransaction();
ss.save(st);
ss.getTransaction().commit();
ss.close();
sf.close();
}
}
Student.hbm.xml

结果编译运行的时候出现了下面的错误,不知道是哪里错了,请高手指点!
