Hibernate environment Construction and configuration method (Hello World Profile Edition) _java

This paper gives an example of how to build and configure hibernate environment. Share to everyone for your reference, specific as follows:

1. Download Hibernate jar Package: hibernate-release-4.3.5.final, import the necessary jar package, the path is: hibernate-release-4.3.5.final\lib\required.

There are 10 jar packages included.

2. Create a new Java project.

3. Learn to build your own user Library:

(a) The project right key--build path--configure build Path--add library.
(b) Select User-library to create a new library in which to name hibernate.
(c) The jar package (path: hibernate-release-4.3.5.final\lib\required) required to add hibernate to the library, Hello World is enough, and the others are added.

4. JDBC driver that introduces the database. I used the Mysql:mysql-connector-java-5.1.7-bin.jar.

(a) Create a database:

Create DATABASE hibernate;

(b) Switching the database:

Use hibernate;

(c) Creation of student tables:

CREATE TABLE Student (ID int primary key,name varchar (), age int);

5. The establishment of Hibernate configuration file Hibernate.cfg.xml, strongly recommended in Hibernate-release-4.3.5.final\documentation\manual\en-us\html_ Copy in the Help document under single path.

Location: 1.1.4. Hibernate configuration. After content modification:

<?xml version= ' 1.0 ' encoding= ' utf-8 '?> <! DOCTYPE hibernate-configuration Public "-//hibernate/hibernate configuration DTD 3.0//en" "http://www.hibernate.org/d Td/hibernate-configuration-3.0.dtd ">  

Establish Student class:

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;
 }
}

To create a Student mapping file: Student.hbm.xml

<?xml version= "1.0"?>
<! DOCTYPE hibernate-mapping public
  "-//hibernate/hibernate mapping DTD 3.0//en"
  "Http://www.hibernate.org/dtd /hibernate-mapping-3.0.dtd ">
 
 

Final Test:

Import org.hibernate.Session;
Import org.hibernate.SessionFactory;
Import org.hibernate.cfg.Configuration;
Import com.huxing.hibernate.model.Student;
public class Studenttest {public
 static void Main (string[] args) {
  Student a = new Student ();
  A.setid (123);
  A.setage (a);
  A.setname ("Hello hibernate!");
  Configuration cfg = new Configuration ();
  Sessionfactory CF = Cfg.configure (). Buildsessionfactory ();
  Session session = Cf.opensession ();
  Session.begintransaction ();
  Session.save (a);
  Session.gettransaction (). commit ();
  Session.close ();
  Cf.close ();
 }

I hope this article will help you to hibernate framework program design.
