QuickServer的学习研究（七）
?? ???? 在项目解析xml的方式很多，常用的如JDOM，dom4j,SAX,DOM,XStream 进行xml的解析，在Struts1.0中解析xml 的方式是通过Commons-Digister实现，同样在QuickServer中也采用同种方式解析相关的方式。
QuickServer中ConfigReader中解析xml的源代码如下：
public static QuickServerConfig read(File input) throws Exception { Digester digester = new Digester(); digester.setValidating(false); String mainTag = "quickserver"; String subTag = ""; digester.addObjectCreate(mainTag, QuickServerConfig.class);
