用Netbean5做的一个用hibernate3查询的小例子,不含WEB部分......
原文:
http://feifan.iblog.cn/index.php ... amp;articleId=81773
1.启动netbean--->new project,选择general类型-->Java Application
Next> 项目名为HiberUserQuery;
project localtion为:e:hiber_test;
project Folder为:e:hiber_testHiberUserQuery
把Main Class改为QueryTest(不打在包里)
Finish.
建好后project的目录结构应如下:
|HiberUserQuery
|--build
|--dist
|--nbproject
|--src
|--com
|--mdc
|--test
|build.xml
|manifest.mf
2.把Hibernate要用到的jar都导入到项目中来
我是把Hibernate要用的到jar都加入到了netbean的library管理器中并命名为Hibernate-3.1,以下为jar文件的列表
ant-antlr-1.6.5.jar
antlr-2.7.6rc1.jar
asm-attrs.jar
asm.jar
cglib-2.1.3.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
dom4j-1.6.1.jar
ehcache-1.1.jar
hibernate3.jar
jaxen-1.1-beta-7.jar
jdbc2_0-stdext.jar
jta.jar
log4j-1.2.11.jar
xml-apis.jar
这样只要右击项目HiberUserQuery中的Libraries-->Add Library,再在列表中选择Hibernate-3.1就可以了。
另:JDBC驱动ojdbc14.jar我放在了%JAVA_HOME%jrelibext下。
3.创建User类和映射
右击项目HiberUserQuery中的Source Packages,选择new-->java package
package Name:com.mdc
右击新建的package,选择new-->Java Class
Class Name:User
User.java
/*
* User.java
*
* Created on 2006年4月26日, 下午12:06
*
* Copyright (c) 2006 Wuxi MDC Co. Ltd.
* All right reserved.
*/
package com.mdc;
/**
*
* @author Chen QingHui
*/
public class User
{
private int id;
private String username;
private String password;
/** Creates a new instance of User */
public User()
{
}
public int getId()
{
return id;
}
public String getName()
{
return username;
}
public String getPass()
{
return password;
}
public void setId(int id)
{
this.id = id;
}
public void setName(String username)
{
this.username = username;
}
public void setPass(String password)
{
this.password = password;
}
}
__________________________________________________________________
User.hbm.xml
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"">
seq_usertable_id
4.在
中,完成QueryTest.java,并在hibernate的发行包中拷贝ehcache.xml,hibernate.cfg.xml,log4j.properties
QueryTest.java
/*
* QueryTest.java
*
* Created on 2006年4月26日, 下午12:22
*
* Copyright (c) 2006 Wuxi MDC Co. Ltd.
* All right reserved.
*/
import com.mdc.*;
import org.hibernate.cfg.*;
import org.hibernate.*;
import java.util.*;
/**
*
* @author Chen QingHui
*/
public class QueryTest
{
/** Creates a new instance of QueryTest */
public QueryTest()
{
}
public static void main(String[] args)
{
try
{
SessionFactory sf = new Configuration().configure().buildSessionFactory();
Session session = sf.openSession();
List users = session.createQuery("from User".list();
session.close();
sf.close();
for (ListIterator iterator = users.listIterator(); iterator.hasNext(); )
{
User user = (User) iterator.next();
System.out.println("Id:" + user.getId() +
"nt名子: " + user.getName() +
"nt密碼: " + user.getPass());
}
}
catch (HibernateException he)
{
he.printStackTrace();
}
}
}
ehcache.xml,hibernate.cfg.xml,log4j.properties只要拷贝到src下,就会自动出现在中了,需要修改hibernate.cfg.xml如下
hibernate.cfg.xml
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"">
ff
jdbcracle:thin192.168.150.200:1521:yxtnj
org.hibernate.dialect.Oracle9Dialect
chen
oracle.jdbc.driver.OracleDriver
5.项目结构如下
最后Build Project,然后run就行了。但事先要准备好数据哦
附:表结构
CREATE TABLE USERTABLE (
ID NUMBER NOT NULL,
USERNAME VARCHAR2(24),
PASSWORD VARCHAR2(24));
序列
CREATE SEQUENCE SEQ_USERTABLE_ID MAXVALUE 1000000000 START WITH 1;
