Example about Hibernate

Phần này tôi sẽ lấy ví dụ về Hibernate là một framework dùng để đơn giản hóa, tự động quá trình thao tác với CSDL.

B1: Tạo CSDL với bảng User
id int(11)
name varchar(255)
B2: Tạo Project trên Eclipse
B3: Tạo file hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
    <!-- ________________ To be Edited _________________ -->
    <!--<property name="connection.url">jdbc_URL</property>
    <property name="connection.username">jdbc_Username</property>
    <property name="connection.password">jdbc_Password</property>-->
    <!-- _____________ End of To be Edited ______________ -->
   
      <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
      <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
      <property name="hibernate.connection.username">root</property>
      <property name="hibernate.connection.password">admin</property>
      <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
      <property name="hibernate.default_schema">test</property>
      <property name="show_sql">true</property>
      <property name="hibernate.hbm2ddl.auto">create</property>
      <!-- _________ Defining the Mapping Files ___________ -->
      <mapping resource="User.hbm.xml"/>
    </session-factory>
</hibernate-configuration>
B4: Tạo file User.hbm.xml

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="com.fis.demo.User" table="User">
        <id  name="id" type="int">
            <column name="id" precision="20" scale="0"/>
            <generator class="increment"></generator>
        </id>
        <property name="name">
            <column name="name"></column>
        </property>
    </class>
</hibernate-mapping>
 B5: Tạo file class User Entity

private int id;
    private String name;
   
    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;
    }


B6: Tạo file Test Hibernate

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Configuration cfg=new Configuration();
        cfg.configure("hibernate.cfg.xml");
        SessionFactory sessionFactory=cfg.buildSessionFactory();
        Session session=sessionFactory.openSession();
        Transaction tx=session.beginTransaction();
       
        User user1=new User();
        user1.setName("Le Van Trung");

        session.save(user1);
        tx.commit();
       
        System.out.println("User " + user1.getName() + "||" + " insert success");
    }
