首先你要下载xdoclet-1.2.3，ant1.6.5，然后写项目管理文件build.properties，build.xml。举例如下：build.properties内容：xdoclet.lib=E:/xdoclet-1.2.3/libbuild.xml内容：<?xml version="1.0" encoding="UTF-8"?><project name="pms" default="" basedir="."><property file="build.properties" /><property name="app.home" value="." /><property name="app.name" value="pms" /><property name="src.dir" value="${app.home}/src" /><path id="xdoclet.classpath"><fileset dir="${xdoclet.lib}"><include name="*.jar" /></fileset></path><!-- =================================================================== --><!-- Initialise --><!-- =================================================================== --><target name="init"><tstamp><format property="TODAY" pattern="d-MM-yy" /></tstamp><taskdef name="hibernatedoclet"classname="xdoclet.modules.hibernate.HibernateDocletTask"classpathref="xdoclet.classpath" /></target><!-- =================================================================== --><!-- The "hibernatedoclet" target generates Hibernate mapping files --><!-- based on XDoclet marked-up Plain Old Java Object (POJO) --><!-- =================================================================== --><target name="hibernatedoclet" depends="init"unless="hibernatedoclet.unnecessary"description="Generate Hibernate mapping files"><taskdef name="hibernatedoclet"classname="xdoclet.modules.hibernate.HibernateDocletTask"classpathref="compile.classpath" /><!-- generate hibernate files --><hibernatedoclet destdir="${src.dir}"mergedir="${src.dir}" excludedtags="@version,@author,@todo,@see"addedtags="@xdoclet-generated at ${TODAY}" force="false"verbose="false"><fileset dir="${src.dir}"><include name="net/pms/model/*.java" /></fileset><hibernate version="3.0" /></hibernatedoclet></target></project>javabean如下：package net.pms.model;import java.io.Serializable;import java.util.Date;import org.apache.commons.lang.builder.ToStringBuilder;import org.apache.commons.lang.builder.HashCodeBuilder;import org.apache.commons.lang.builder.EqualsBuilder;/**** @author jfish* @hibernate.class table="person"*/public class Person implements Serializable {private static final long serialVersionUID = 1044237873392048222L;private Long id;private String name;private Date createTime;/*** @return Returns the createTime.* @hibernate.property column = "ts"*/public Date getCreateTime() {return createTime;}/*** @param createTime* The createTime to set.*/public void setCreateTime(Date createTime) {this.createTime = createTime;}/*** @return Returns the id.* @hibernate.id column = "person_id" generator-class = "native"* unsaved-value = "not null"*/public Long getId() {return id;}/*** @param id* The id to set.*/public void setId(Long id) {this.id = id;}/*** @return Returns the name.* @hibernate.property*/public String getName() {return name;}/*** @param name* The name to set.*/public void setName(String name) {this.name = name;}/*** @see java.lang.Object#toString()*/public String toString() {return new ToStringBuilder(this).append("name", this.name).append("id",this.id).append("createTime", this.createTime).toString();}/*** @see java.lang.Object#hashCode()*/public int hashCode() {return new HashCodeBuilder(-96436153, 713792057).appendSuper(super.hashCode()).append(this.createTime).append(this.name).append(this.id).toHashCode();}/*** @see java.lang.Object#equals(Object)*/public boolean equals(Object object) {if (!(object instanceof Person)) {return false;}Person rhs = (Person) object;return new EqualsBuilder().appendSuper(super.equals(object)).append(this.createTime, rhs.createTime).append(this.name, rhs.name).append(this.id, rhs.id).isEquals();}}生成的映射文件如下：<?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="net.pms.model.Person" table="person"><id name="id" column="person_id" type="java.lang.Long"unsaved-value="not null"><generator class="native"><!--To add non XDoclet generator parameters, create a file namedhibernate-generator-params-Person.xmlcontaining the additional parameters and place it in your merge dir.--></generator></id><property name="createTime" type="java.util.Date" update="true"insert="true" column="ts" /><property name="name" type="java.lang.String" update="true"insert="true" column="name" /><!--To add non XDoclet property mappings, create a file namedhibernate-properties-Person.xmlcontaining the additional properties and place it in your merge dir.--></class></hibernate-mapping>
