This is my Employee entity class
这是我的Employee实体类
package com.samples.hibernate;
public class Employee {
private int ID;
private String name;
public int getID() {
return ID;
}
public void setID(int iD) {
ID = iD;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Here is my code where I am communicating with the database.
这是我与数据库通信的代码。
public static void main(String[] args) {
// TODO Auto-generated method stub
Configuration configuration = new Configuration().configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory factory = configuration.buildSessionFactory(builder.build());
Session session = null;
try
{
session = factory.openSession();
Employee employee = new Employee();
employee.setID(3);
employee.setName("Venkatesh");
session.beginTransaction();
session.save(employee);
session.getTransaction().commit();
}
catch(Exception e)
{
e.printStackTrace();
}
finally
{
session.close();
}
}
Class Employee has ID as integer and name as String. Please help me with this. I am new to hibernate and trying to learn. Thank You in advance.

It is solved. I recreated .hbm.xml file. Maybe it was taking int as datatype for name.
它解决了。我重新创建了.hbm.xml文件。也许它将int作为name的数据类型。
