Java Tutorial/Hibernate/Inner Property Mapping

Read Component Properties Out

File: Main.java

   <source lang="java">

import java.util.List; import org.hibernate.Query; import org.hibernate.Session; public class Main {

 public static void main(String[] args) throws Exception {
   HibernateUtil hibernateUtil = new HibernateUtil();
   hibernateUtil
       .executeSQLCommand("create table CD(id varchar,title varchar,purchaseDate date,cost decimal(6,2),countryCode varchar,areaCode varchar)");

Use Component To Map Member Type

File: Main.java

   <source lang="java">

import org.hibernate.Session; public class Main {

 public static void main(String[] args) throws Exception {
   HibernateUtil hibernateUtil = new HibernateUtil();
   hibernateUtil
       .executeSQLCommand("create table CD(id varchar,title varchar,purchaseDate date,cost decimal(6,2),countryCode varchar,areaCode varchar)");
   Session session = hibernateUtil.getSession();
   CD cd = new CD();
   cd.setArtist("artist");
   cd.setTitle("title");
   SerialNumber serial = new SerialNumber();
   serial.setAreaCode("1");
   serial.setCountryCode("1");
   
   cd.setSerial(serial);
   
   String id = (String)session.save(cd);
   System.out.println(id);
   session.flush();
   session.close();
   hibernateUtil.checkData("select * from CD");
 }
