2, first we introduce the corresponding jar package

it's used here. Oracle 11g , so we used a database connection Jar Package is Ojdbc5

3. We configure the corresponding entity objects in the database

Producttype.java

/** * Features: This is the product category * File: Producttype.java * Time: May 12, 2015 10:16:21 * cutter_point */package com.cutter_point.bean.product; publicclassproducttype{    private Integer typeid;       Public Integer GetTypeId ()    {        returntypeid;    }     Publicvoid Settypeid (Integertypeid)    {        This.typeid = typeid;    }}

Product.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 "> 


4. We configure Hibernate connection file
<?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 "> 

5. Next we test if Hibernate is configured successfully
/** * Features: This is the unit test for the product category * File: Producttest.java * Time: May 12, 2015 10:27:24 * cutter_point * * Package junit.test; Import Org.hibernate.session;import Org.hibernate.sessionfactory;import Org.hibernate.cfg.configuration;import Org.junit.beforeclass;import org.junit.Test; Import Com.cutter_point.bean.product.ProductType; publicclassproducttest{@BeforeClass publicstaticvoid Setupbeforeclass () throws Exception {} @SuppressWa Rnings ("deprecation") @Test publicvoid Test () {producttypept = Newproducttype ();//new an object Pt.sett   Ypeid (78);    Set ID Number configurationcfg = newconfiguration (); Get the configuration SESSIONFACTORYSF = Cfg.configure ("/config/hibernate/hibernate.cfg.xml"). Buildsessionfactory ();        Get Session Factory Sessionsession = Sf.opensession ();        Session.begintransaction ();        Session.save (PT);        Session.gettransaction (). commit ();        Session.close ();    Sf.close (); } }


6. Summary
This configuration hibernate is very simple, but note that if your database does not have a corresponding table, or if you do not write SQL statements, or you think you write the SQL statement is not allowed, then there is a method, the Hibernate configuration file  Hibernate.cfg.xml inside.
<property name="Hbm2ddl.auto">update</ update  in property> to Create, then  Hibernate will automatically help you create the appropriate table
