Hibernate 逆向工程生成POJO类和映射文件

Guestbook.java

代码：

package com.b510.examplex;

import java.util.Date;

public class Guestbook implements java.io.Serializable {

 private static final long serialVersionUID = -7004492417383895995L;  private Integer id;  private String name;  private String email;  private String phone;  private String title;  private String content;  private Date createdTime;

 // Constructors

 /**   * @return the name   */  public String getName() {   return name;  }

 public Integer getId() {   return this.id;  }

 public void setId(Integer id) {   this.id = id;  }

 /**   * @param name   *            the name to set   */  public void setName(String name) {   this.name = name;  }

 /**   * @return the email   */  public String getEmail() {   return email;  }

 /**   * @param email   *            the email to set   */  public void setEmail(String email) {   this.email = email;  }

 /**   * @return the phone   */  public String getPhone() {   return phone;  }

 /**   * @param phone   *            the phone to set   */  public void setPhone(String phone) {   this.phone = phone;  }

 /**   * @return the title   */  public String getTitle() {   return title;  }

 /**   * @param createdTime   *            the createdTime to set   */  public void setCreatedTime(Date createdTime) {   this.createdTime = createdTime;  }

 /** default constructor */  public Guestbook() {  } }

Guestbook.hbm.xml

代码：

<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping>  <class name="com.b510.examplex.Guestbook" table="guestbook"   catalog="users">   <id name="id" type="java.lang.Integer">    <column name="id" />    <generator class="increment" />   </id>   <property name="name" type="java.lang.String">    <column name="name" length="200" />   </property>   <property name="email" type="java.lang.String">    <column name="email" length="50" />   </property>   <property name="phone" type="java.lang.String">    <column name="phone" length="20" />   </property>   <property name="title" type="java.lang.String">    <column name="title" length="200" />   </property>   <property name="content" type="java.lang.String">    <column name="content" length="1000" />   </property>   <property name="createdTime" type="java.util.Date">    <column name="created_time" length="10" />   </property>  </class> </hibernate-mapping>

测试代码：HibernateTest.java

代码：

/**  *  */ package com.b510.examplex;

import org.hibernate.Session; import org.hibernate.Transaction;

/**  *  * @author XHW  *  * @date 2011-7-8  *  */ public class HibernateTest {

 /**   * @param args   */  public static void main(String[] args) {   HibernateTest test = new HibernateTest();   test.testTransaction();  }

 public void testTransaction() {   Session session = HibernateSessionFactoryUtil.getSessionFactory()     .openSession();   Transaction tx = session.beginTransaction();

  Guestbook guestbook = new Guestbook();   guestbook.setName("Hongten");   guestbook.setPhone("123456");   guestbook.setEmail("hongtenzone@foxmail.com");   guestbook.setTitle("hello world!");   guestbook.setContent("hello world!hello world!");   guestbook.setCreatedTime(new java.util.Date());

  try {    session.save(guestbook);   } catch (Exception e) {    e.printStackTrace();    if (tx.isActive()) {     tx.rollback();    }   }   tx.commit();  }

}

运行效果：
