用xxx.hbm.xml映射文件配置的hibernate实例

一、实体类bean：News.java

package edu.hzu.entity;

import java.util.Date;

/**
* @hibernate.class table="t_news"
* @author laoyang
*/
public class News {

/**
* @hibernate.property
* @return
*/
public String getContent() {
return content;
}

public void setContent(String content) {
this.content = content;
}

/**
* @hibernate.id generator-class="native"
* @return
*/
public Integer getId() {
return id;
}

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

/**
* @hibernate.many-to-one class="edu.hzu.entity.NewsCategory" column="news_category_id"
* @return
*/
public NewsCategory getNewsCategory() {
return newsCategory;
}

public void setNewsCategory(NewsCategory newsCategory) {
this.newsCategory = newsCategory;
}

/**
* @hibernate.property
* @return
*/
public int getOrderIndex() {
return orderIndex;
}

public void setOrderIndex(int orderIndex) {
this.orderIndex = orderIndex;
}

/**
* @hibernate.property
* @return
*/
public Date getPublishdate() {
return publishdate;
}

public void setPublishdate(Date publishdate) {
this.publishdate = publishdate;
}

/**
* @hibernate.property
* @return
*/
public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

private Integer id;
private String title;
private Date publishdate;
private String content;
private int orderIndex;
private NewsCategory newsCategory;

}

2、hibernate.cfg.xml配置文件

<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>

<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/test</property>
<property name="connection.username">root</property>
<property name="connection.password">root</property>

<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>

<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>

<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>

<mapping resource="edu/hzu/entity/news.hbm.xml"/>

</session-factory>

</hibernate-configuration>

3、xxx.hbm.xml映射文件

<?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="edu.hzu.entity.News" table="t_news">

<id name="id" column="id" type="java.lang.Integer">
<generator class="native"/>
</id>

<property name="content" type="java.lang.String" column="content"/>

<property name="title" type="java.lang.String" column="title"/>

<many-to-one name="newsCategory" class="edu.hzu.entity.NewsCategory" cascade="none" outer-join="auto" column="news_category_id"/>

<property name="orderIndex" type="int" column="orderIndex"/>

<property name="publishdate" type="java.util.Date" column="publishdate"/>

</class>

</hibernate-mapping>

4、测试类

package edu.hzu.test;

import org.hibernate.cfg.Configuration;
import org.hibernate.classic.Session;

public class Test {

public static void main(String[] args) {
Configuration configuration = new Configuration().configure();
configuration.buildSessionFactory().openSession();
}
}

运行这个测试类就可以得到对应的数据库及表（当然这只是写了一个例子，其实只是一个框架，要真运行，还要类似建一个NewsCategory类，与News相似）
