hibernate 最入门简单配置

下载得到的为http://sourceforge.net/projects/hibernate/files/hibernate4/4.3.0.Beta2/hibernate-release-4.3.0.Beta2.zip/download

得到的是hibernate-release-4.3.0.Beta2

这程序实现向数据库中插入记录

输入hibernate之后

之后导入工程。

接下来配置结构如下图

User.java代码如下

View Code

 1 package javamxj.hibernate;
 2 import java.util.Date;
 3 public class User {
 4 
 5     /**
 6      * @param args
 7      */
 8     private int id;
 9     private String username;
10     private String password;
11     
12     public int getId() {
13         return id;
14     }
15     public void setId(int id) {
16         this.id = id;
17     }
18     public String getUsername() {
19         return username;
20     }
21     public void setUsername(String username) {
22         this.username = username;
23     }
24     public String getPassword() {
25         return password;
26     }
27     public void setPassword(String password) {
28         this.password = password;
29     }
30 
31     
32 }

hibernate.cfg.xml代码如下

View Code

 1 <?xml version='1.0' encoding='GBK'?>
 2 <!DOCTYPE hibernate-configuration PUBLIC
 3     "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 4     "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
 5 
 6 
 7 <hibernate-configuration>
 8 
 9     <session-factory>
10 
11         <!-- 是否将运行期生成的SQL输出到日志以供调试 -->
12         <property name="show_sql">true</property>
13         
14         <!-- SQL方言，这里设定的是MySQL -->
15         
16         <property name="hibernate.dialect">org.hibernate.dialect.H2Dialect</property>
17         
18         <!-- JDBC驱动程序 -->
19         <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
20         
21         <!-- JDBC URL, "?useUnicode=true&amp;characterEncoding=GBK" 表示使用GBK进行编码 -->
22         <property name="connection.url">
23       jdbc:mysql://localhost:3306/HibernateTest?useUnicode=true&amp;characterEncoding=GBK
24         </property>
25         
26         <!-- 数据库用户名 -->
27         <property name="connection.username">root</property>
28         
29         <!-- 数据库密码 -->
30         <property name="connection.password"> your password</property>
31 
32         <!-- 指定User的映射文件 -->
33         <mapping resource="javamxj/hibernate/User.hbm.xml"/>       
34 
35     </session-factory>
36 
37 </hibernate-configuration>

User.hbm.xml代码如下

View Code

 1 <?xml version="1.0" encoding="GBK"?>
 2 <!DOCTYPE hibernate-mapping PUBLIC
 3         "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 4         "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
 5     
 6 <hibernate-mapping>
 7 
 8     <class name="javamxj.hibernate.User" table="UserTable">
 9         <id name="id" >
10             <generator class="assigned" />
11         </id>
12         <property name="username"  />
13         <property name="password" />        
14     </class>
15 
16 </hibernate-mapping>

Test.java代码如下

View Code

 1 package javamxj.hibernate;
 2 
 3 import org.hibernate.HibernateException;
 4 import org.hibernate.Session;
 5 import org.hibernate.SessionFactory;
 6 import org.hibernate.Transaction;
 7 import org.hibernate.cfg.Configuration;
 8 
 9 public class Test {
10 
11     /**
12      * @param args
13      */
14     public static void main(String[] args) {
15 
16         try {
17             SessionFactory sf = new Configuration().configure()
18                     .buildSessionFactory();
19             Session session = sf.openSession();
20             Transaction tx = session.beginTransaction();
21 
22             User user = new User();
23             user.setUsername("wf");
24             user.setPassword("xxxx");
25 
26             session.save(user);
27             tx.commit();
28             session.close();
29 
30         } catch (HibernateException e) {
31             e.printStackTrace();
32         }
33     }
34 
35 }

接下来配置数据库

create HibernateTest;

use HibernateTest;

create table usertable(ID int(6) not null auto_increment,username varchar(24) not null default '',password varchar(24) not null default '', primary key (ID));

用select* from usertable查询

程序执行下数据表中就多一条记录。
