hibernate-4.3.5 installation Configuration

At first, according to official documents, always error, seemingly official documents wrong, looked up a lot of information, a comprehensive collation of a feasible solution, as follows:

0.1 Package Structure

1.POJO as follows

Package Test.domain;public class Message {private Long id;private String text;private message nextmessage;public message ( String text) {this.text = text;} Public Long GetId () {return ID;} public void SetId (Long id) {this.id = ID;} Public String GetText () {return text;} public void SetText (String text) {this.text = text;} Public Message Getnextmessage () {return nextmessage;} public void Setnextmessage (Message nextmessage) {this.nextmessage = Nextmessage;}}

2. mapping file corresponding to it Message.hbm.xml, note, to be put together with Pojo

<?xml version= "1.0" encoding= "UTF-8"? ><! DOCTYPE hibernate-mapping public        "-//hibernate/hibernate mapping DTD 3.0//en"        "Http://www.hibernate.org/dtd /hibernate-mapping-3.0.dtd ">        

3.hibernate.cfg.xml, hibernate configuration file, placed in src root directory
<?xml version= ' 1.0 ' encoding= ' utf-8 '? ><! DOCTYPE hibernate-configuration Public "-//hibernate/hibernate configuration DTD 3.0//en" "Http://www.hibern Ate.org/dtd/hibernate-configuration-3.0.dtd ">
4.hibernateutil.java Tool Class
package Test.util;import Org.hibernate.sessionfactory;import Org.hibernate.boot.registry.StandardServiceRegistryBuilder; Import Org.hibernate.cfg.configuration;import Org.hibernate.service.serviceregistry;public class HibernateUtil { private static final Sessionfactory sessionfactory = buildsessionfactory ();p rivate static sessionfactory Buildsessionfactory () {try {configuration configuration = new configuration ().

5. Testing
Package Test.demo;import Org.hibernate.session;import Test.domain.message;import test.util.hibernateutil;public Class HelloWorld {public static void main (string[] args) {Session session = Hibernateutil.getsessionfactory (). Opensession ();        Session.begintransaction ();        Message message = new Message ("Hello,world"); session.save (message); Session.gettransaction (). commit ();}}
