對(duì)于Hibernate2,要下載hibernate-extensions,把hibernate-tools.jar放入classpath中.
Ant的腳本如下:
<!-- property definition omitted -->
<taskdef name="hbm2java" classname="net.sf.hibernate.tool.hbm2java.Hbm2JavaTask" classpathref="project.class.path" />

<target name="codegen" description="Generate Java source from the O/R mapping files">
<hbm2java output="${source.root}">
   <fileset dir="${source.root}">
    <include name="**/*.hbm.xml" />
   </fileset>
</hbm2java>
</target>

----------------------------------------------------------

對(duì)于Hibernate3,則要下載對(duì)應(yīng)的HibernateTools包,這里以HibernateTools-3.2.0.GA.zip舉例.
把其中的/plugins/org.hibernate.eclipse_3.2.0.GA/lib/tools目錄下:
hibernate-tools.jar 和 freemarker.jar 包c(diǎn)opy到classpath中.
Ant的腳本如下:
<taskdef name="hbm2java" classname="org.hibernate.tool.ant.HibernateToolTask" classpathref="project.class.path" />

<target name="codegen" description="Generate Java source from the O/R mapping files">
<hbm2java destdir="${source.root}">
  <configuration>
    <fileset dir="${source.root}">
     <include name="**/*.hbm.xml" />
    </fileset>
  </configuration>
  <hbm2java /><!-- this should be added to show this is a hbm2java task -->
</hbm2java>
</target>
