1: 创建工程并添加必要的java包，创建完成后工程如下：
2：配置hibernate.cfg.xml文件
1 <?xml version='1.0' encoding='UTF-8'?>
2 <!DOCTYPE hibernate-configuration PUBLIC
3 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
4 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
5
6 <hibernate-configuration>
7
8 <session-factory>
9 <property name="connection.username">root</property>
10 <property name="connection.password">root</property>
11 <property name="connection.url">
12 jdbc:mysql://127.0.0.1:3306/ssh0
13 </property>
14 <property name="dialect">
15 org.hibernate.dialect.MySQLDialect
16 </property>
17 <property name="connection.driver_class">
18 com.mysql.jdbc.Driver
19 </property>
20 <mapping resource="com/lei/vo/ADM_MENU.hbm.xml" />
21 <!--mapping resource="com/lei/vo/USER.hbm.xml" /> -->
22
23 </session-factory>
24
25 </hibernate-configuration>
3：编写对象的hbm文件，如：ADM_MENU.hbm.xml
1 <?xml version="1.0" encoding="utf-8"?>
2 <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
3 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
4 <hibernate-mapping>
5 <class name="com.lei.vo.ADM_MENU" table="ADM_MENU" catalog="ssh0">
6 <id name="MENUID" type="string">
7 <column name="MENUID" length="20" not-null="true" />
8 <generator class="assigned" />
9 </id>
10 <property name="MENUNAME" type="string">
11 <column name="MENUNAME" length="20" not-null="true" />
12 </property>
13 <property name="PARANTID" type="string">
14 <column name="PARANTID" length="20" not-null="true" />
15 </property>
16 <property name="URL" type="string">
17 <column name="URL" length="100" not-null="true" />
18 </property>
19 </class>
20 </hibernate-mapping>
21
4： 编写ant脚本bulid.xml
<?xml version="1.0" encoding="GBK"?>

<hbm2ddl export="true" console="false" create="true" update="false" drop="true" outputfilename="orm_createdb.sql"/>
</hbm2ddl>
</target>
</project>
5：在eclipse outline视图中执行hbm2ddlonly生成数据库脚本并建库和hbm2javaonly生成java对象
6：编写测试案例测试hibernate
1 package com.lei.util;
2
3 import org.hibernate.SessionFactory;
4 import org.hibernate.cfg.Configuration;
5
6 public class HibernateUtil {
7
8 private static final SessionFactory sessionFactory;
9
10 static {
11 try {
12 // Create the SessionFactory from hibernate.cfg.xml
13 sessionFactory = new Configuration().configure().buildSessionFactory();
14 } catch (Throwable ex) {
15 // Make sure you log the exception, as it might be swallowed
16 System.err.println("Initial SessionFactory creation failed." + ex);
17 throw new ExceptionInInitializerError(ex);
18 }
19 }
20
21 public static SessionFactory getSessionFactory() {
22 return sessionFactory;
23 }
24
25 }
1 package com.lei.test.hibernate;
2
3 import org.hibernate.Session;
4 import org.junit.After;
5 import org.junit.Assert;
6 import org.junit.Before;
7 import org.junit.Test;
8
9 import com.lei.util.HibernateUtil;
10 import com.lei.vo.ADM_MENU;
11
12 public class TestHibernate {
13
14 private Session session ;
15
16 @Before
17 public void setUp() throws Exception {
18 session = HibernateUtil.getSessionFactory().openSession();
19 session.beginTransaction();
20 }
21
22 @After
23 public void tearDown() throws Exception {
24 session.getTransaction().rollback();
25 session.close();
26 }
27
28 @Test
29 public void testAddAndQuery(){
30 ADM_MENU aMenu = new ADM_MENU();
31 aMenu.setMENUID("10000");
32 aMenu.setMENUNAME("测试");
33 aMenu.setPARANTID("100000");
34 aMenu.setURL("10000.action");
35 session.save(aMenu);
36 ADM_MENU menu1 = (ADM_MENU) session.get(ADM_MENU.class, new String("10000"));
37 Assert.assertEquals(menu1.getPARANTID(), "100000");
38 }
39
40 @Test
41 public void testDelete(){
42
43
44 }
45
46 }

7:运行junit测试案例，看到绿色了把
。
