eclipse 中 使用Hibernate Tools 3.4 从数据库方向生成 hibernate 配置文件

eclispe 不想Myeclipse里面有自带的反响 从数据库里面生成 配置文件和类。但eclipse很友好，可能容纳各种插件，想装什么，就装什么，不走寻常路。首先到hibernate 的老窝去下载Hibernate Tools 插件，网站为：http://download.jboss.org/jbosstools/updates/development/indigo/，

在eclipse里面，windiow --->preferneces-->install ,输入，会跑出来一堆控件，选择Hibernate Tools 3.4即可（该网站是jboss 所有控件），安装，重启eclipse 。

如果你工程的五文件是采取SSH架构，而且，你的数据数配置，又放在该死的APPlication 上，很不幸的，你要重新生成一份hibernate配置文件，包括数据库URL ，方言，JDBC，用户名，密码等配置。

本文的配置：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory name="ddc">

<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

<property name="hibernate.connection.url">jdbc:oracle:thin:@ip:database</property>

<!--指定连接数据库的用户名-->

<property name="connection.username">POSTMOBILE</property>

<property name="connection.password">POSTMOBILE</property>

<property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>

</session-factory>

</hibernate-configuration>

由此配置文件，接下来，当然是 反响生成文件了，hibernate，像Myeclipse那样，直接生成，它是先生成，反响配置文件。装了Hibernate Tools 3.4，后，在eclipse new 菜单里

接下来，根据提示，导入刚才的配置文件，然后选择你要的生成的表即可；

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>

<table-filter match-schema="POSTMOBILE" match-name="TB_MAILINFO"/>

<table-filter match-schema="POSTMOBILE" match-name="TB_TRACE"/>

</hibernate-reverse-engineering>

生成的反响文件，

最后一步，就是根据方向配置文件，编译一下，生成你所需要的，类文件，和对该类hibernate配置文件，run-->hibernate code generatin.

Hibernate tools

Hibernate Tools is a database reverse engineering tool that can generate domain model classes and Hibernate mapping files, annotated EJB3 entity beans, HTML documentation or even an entire JBoss Seam application in seconds!

> how to use hibernate tools
1. modify hibernate.cfg.xml

For oracle you should add following element to your .cfg.xml:

<hibernate-configuration>
<session-factory>
...
<property name="hibernate.default_schema">YOUR_SCHEMANAME_IN_UPPERCASE</property>
...
</session-factory>
</hibernate-configuration>

2. open perspective... -> Hibernate
3. create Hibernate Console Configuration:-
4. create reverse engine file:-
copy from below sample file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>
<table-filter match-name="YY_ICCODE" />
<table name="YY_ICCODE" class="Yy_iccode" schema="YB"></table>
</hibernate-reverse-engineering>

5. generate code:-

menu Run->Hibernate Code Generation...->Hibernate Code Generation Configuration...,




Exporters tab:
选择domain code和hibernate xml mapping

click "run"

sample reverse engine file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >

<hibernate-reverse-engineering>
<table-filter match-name="YY_ICCODE" />
<table name="YY_ICCODE" class="Yy_iccode" schema="YB"></table>
</hibernate-reverse-engineering>
