通过读取源代码,发现struts2是通过Xwork中的XmlConfigurationProvider来读取配置的.其中发现在xwork2.1版本中,是支持*号的通配读取.但在xwork2.0中是不支持这样的写法.

所以在String2.1的版本中是可以使用<include file="resource/struts-config/*.xml"/>这样的配置.在Struts2.0中是不支持这样的配置

xwork2.1

Java代码  

1. if ("include".equals(nodeName)) {   
2.                             String includeFileName = child.getAttribute("file");   
3.                             if (includeFileName.indexOf('*') != -1) {
     
4.                                 // handleWildCardIncludes(includeFileName, docs, child);
     
5.                                 ClassPathFinder wildcardFinder = new ClassPathFinder();   
6.                                 wildcardFinder.setPattern(includeFileName);   
7.                                 Vector<String> wildcardMatches = wildcardFinder.findMatches();   
8.                                 for (String match : wildcardMatches) {   
9.                                     finalDocs.addAll(loadConfigurationFiles(match, child));   
10.                                 }   
11.                             } else {   
12.                                 finalDocs.addAll(loadConfigurationFiles(includeFileName, child));   
13.                             }   
14.                         }  

xwork2.0

Java代码  

1. Element rootElement = doc.getDocumentElement();   
2.                 NodeList children = rootElement.getChildNodes();   
3.                 int childSize = children.getLength();   
4.   
5.                 for (int i = 0; i < childSize; i++) {
     
6.                     Node childNode = children.item(i);   
7.   
8.                     if (childNode instanceof Element) {   
9.                         Element child = (Element) childNode;   
10.   
11.                         final String nodeName = child.getNodeName();   
12.   
13.                         if (nodeName.equals("include")) {   
14.                             String includeFileName = child.getAttribute("file");   
15.                             docs.addAll(loadConfigurationFiles(includeFileName, child));   
16.                         }   
17.                     }   
18.                 }   
19.                 docs.add(doc);   
20.                 loadedFileUrls.add(url.toString
