自动从xml页面生成java swing界面的功能，不过比较简单： xslt可能生成web页面，也就是html或者其它脚本型的界面比较方便。

配置文件：

<?xml version="1.0" encoding="UTF-8"?><config><ConfigDialogTitle>BMC Patrol 采集配置</ConfigDialogTitle><ConfigGroup><title>基本配置</title><configItem name="采集点名称"></configItem><configItem name="采集点描述"></configItem><configItem name="采集点ID"></configItem></ConfigGroup><ConfigGroup><title>Patrol Agent连接配置</title><configItem name="Patrol Agent ip"></configItem> <configItem name="Patrol Agent 端口"></configItem><configItem name="Patrol Agent 用户"></configItem><configItem name="Patrol Agent 密码"></configItem></ConfigGroup></config>

代码：

Digester digest=new Digester(); digest.addObjectCreate("config","com.ubi.config.demo.ConfigDialog"); digest.addCallMethod("config/ConfigDialogTitle","setTitle", 0); digest.addObjectCreate("config/ConfigGroup", "com.ubi.config.demo.ConfigTab"); digest.addCallMethod("config/ConfigGroup/title","setName",0); digest.addCallMethod( "config/ConfigGroup/configItem", "addConfigItem", 1 ); digest.addCallParam( "config/ConfigGroup/configItem", 0,"name" ); digest.addSetNext( "config/ConfigGroup", "addConfigTab" ); try { BufferedReader r=new BufferedReader(new StringReader(cfgTemplate)); Object obj=digest.parse(r); ConfigDialog dlg=(ConfigDialog)obj; dlg.setReaderTypeID(this.readerTypeIntID); dlg.setSize(new Dimension(600,400)); dlg.show(); System.out.PRintln("parsed object is "+obj); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (SAXException e) { // TODO Auto-generated catch block e.printStackTrace(); }
