XDoclet 是一个面向属性的java代码生成器，它使java也具有.net的属性能力。要实现XDoclet的功能，就要借助Ant，因为XDoclet实质是Ant的一项任务。

1. 继承DocletTask类，定义自己的Ant的任务。

代码如下：

package demo;

import org.apache.log4j.Logger;

import xdoclet.DocletTask;

public class DemoDoclet extends DocletTask

{

/** *//**

* Logger for this class

private static final Logger logger = Logger.getLogger(DemoDoclet.class);

public DemoDoclet()

{

logger.info("DemoDoclet start

.!");

//this.addSubTask(new DemoDocletSubTask()); 实现DocletTask的子任务，其实不需要在这里实例子任务，只要在xdoclet.xml声明就可以。

}

如果要实现DocletTask的子任务。代码如下：

package demo;

import org.apache.log4j.Logger;

import xdoclet.XDocletException;

import xdoclet.SubTask;

public class DemoDocletSubTask extends SubTask

{

/** *//**

* Logger for this class

private static final Logger logger = Logger

.getLogger(DemoDocletSubTask.class);

public DemoDocletSubTask()

{

super();

// TODO Auto-generated constructor stub

}

public void execute() throws XDocletException

{

// TODO Auto-generated method stub

logger.info("DemoDocletSubTask start xml

.!");

}

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

< xdoclet-module >

< subtask

name ="demodoclettask"

implementation-class ="demo.DemoDocletSubTask"

parent-task-class ="demo.DemoDoclet"

</ xdoclet-module >

2.Ant的任务实现。
代码如下：

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

< project name ="XDoclet Generator" default ="_xdoclet_generation_" >

< property file ="xdoclet-build.properties" />

< property name ="eclipse.home" value ="D:/eclipse3.1/eclipse" />

< property name ="xdoclet.basedir" value ="${eclipse.home}/plugins/org.jboss.ide.eclipse.xdoclet.core_1.5.0.M2" />

< property name ="jboss.net.version" value ="4.0" />

< property name ="xdoclet.lib.dir" value ="d:/xdoclet-bin-1.2.3/lib" />

< property name ="build.dir" value ="." />

< property name ="build.classes.dir" value ="${build.dir}/classes" />

< property name ="build.src.dir" value ="${build.dir}/src" />

< path id ="project.classpath" >

< pathelement location ="classes" />

< pathelement location ="D:/xdoclet-bin-1.2.3/lib/xdoclet-1.2.3.jar" />

< pathelement location ="D:/xdoclet-bin-1.2.3/lib/xjavadoc-1.1.jar" />

< pathelement location ="D:/ant-1.6.5/apache-ant-1.6.5/lib/ant.jar" />

< pathelement location ="D:/xdoclet-bin-1.2.3/lib/log4j.jar" />

</ path >

< path id ="xdoclet.classpath" >

< path refid ="project.classpath" />

< fileset dir ="${xdoclet.lib.dir}" >

< include name ="*.jar" />

< exclude name ="xdoclet-module-jboss-net-*.jar" />

</ fileset >

< fileset dir ="${xdoclet.basedir}" >

< include name ="xdoclet-module-jboss-net-${jboss.net.version}*.jar" />

</ fileset >

</ path >

<!-- =================================

target: demodoclet

================================= -->

< target name ="demodoclet" description ="--> description" >

< taskdef name ="demodoclet" classname ="demo.DemoDoclet" classpathref ="xdoclet.classpath" />

< demodoclet destdir ="${build.src.dir}" excludedtags ="@version,@author,@todo,@see" addedtags ="@xdoclet-generated at TODAY,@copyright The XDoclet Team,@author XDoclet,@version version" force ="false" verbose ="false" >

< fileset dir ="${build.src.dir}" >

< include name ="*.java" />

</ fileset >

< demodoclettask />

</ demodoclet >

</ target >

< target name ="_xdoclet_generation_" depends ="demodoclet" />

</ project >

运行结果如下：

Buildfile: xdoclet-build.xml

demodoclet:
[demodoclet] (demo.DemoDoclet                     15 ) DemoDoclet start....!
[demodoclet] (XDocletMain.start                   47 ) Running <demodoclettask/>
[demodoclet] (demo.DemoDocletSubTask              22 ) DemoDocletSubTask start xml....!
[demodoclet] (XDocletMain.start                   47 ) Running <demodoclettask/>
[demodoclet] (demo.DemoDocletSubTask              22 ) DemoDocletSubTask start xml....!
