OO类图--〉数据库设计--〉MiddleGen (能够处理基本的关联关系--打开XDoclet标签生成开关，但不能处理继承概念，较为遗憾ing)-->在Eclipse手工更新Java类中 的XDoclet标签，然后XDoclet生成Hbm文件。当然了再写个JUnit测试一下关联关系是否正确，必要的Lazy是否标注。

下载Template： http://raibledesigns.com/wiki/Wiki.jsp?page=XDocletEclipse#hibcolidx 非常感谢MattRaible.

在中文环境中，window xp的字符切换键与Eclipse模版的字符快捷键重合，需要修改之。为了避免麻烦，直接修改Template文件，简单添加@标示符：全文如下：

使用时：先把XML内容单独保存为文件，然后在Eclipse-->Windows-->Preferences
                                     在Preferences-->Java-->Editor-->Templates 点击Import按钮导入之前已经保存的XML文件。

方法2：
OO类图--〉在Eclipse手工编写属性--〉生成Get/Set方法--〉更新Java类中 的XDoclet标签，然后XDoclet生成Hbm文件。当然了再写个JUnit测试一下关联关系是否正确，必要的Lazy是否标注。
要求先修改Get方法的模板：源代码编辑器中鼠标右键--〉Source--〉Generate Getters And Setters..

               点击打开面板中Code Template链接。

编辑Getter方法模板：
/**
 * @hibernate.property name="${bare_field_name}" column="${field}" type="${field_type}" not-null="false" unique="false" length="128"
 * @return Returns the ${bare_field_name}.
 */
然后生成代码，手工微调部分属性。也能够节约大量时间。

注意：在编写Java POJO类时，java属性用完整的带包名的类，例如：
/**
* @author jdyao
 * @hibernate.class table="respri"
 * @version
 */
public class Resource implements Serializable {

    private static final long serialVersionUID = 1505581058179605003L;

    private java.lang.String guid;

    private java.lang.String context;

 

    public Resource () {

    }

    /**
     * @return java.lang.String
     * @hibernate.property name="context" type="java.lang.String"
     *                     length="128"
     *
     */
    public java.lang.String getContext() {
        return context;
    }

    public void setContext(java.lang.String context) {
        this.context = context;
    }

    /**
     * @return java.lang.String
     * @hibernate.id generator-class="guid" type="java.lang.String" column="guid"
     *               unsaved-value="null" length="38"
     */
    public java.lang.String getGuid() {
        return guid;
    }

    public void setGuid(java.lang.String guid) {
        this.guid = guid;
    }
}
原因：XDoclet在生成的时候，如果type="string",有时会出现错误，无法生成Hbm文件，为了避免这个不必要的错误，务必要写全类名。

工程目录结构：从XDoclet网站下载该包，解压缩后，把Example目录单独copy出来，把这2个文件放在Example目录下，同时建立lib目录，把XDoclet目录下--〉lib目录下的*.jar拷贝到Example新建立的lib目录下。
