再来看第二步：init_TraditionalXmlConfigurations()

protected PackageConfig addPackage(Element packageElement) throws ConfigurationException { PackageConfig.Builder newPackage = buildPackageContext(packageElement); if (newPackage.isNeedsRefresh()) { return newPackage.build(); } // add result types (and default result) to this package addResultTypes(newPackage, packageElement); // load the interceptors and interceptor stacks for this package loadInterceptors(newPackage, packageElement); // load the default interceptor reference for this package loadDefaultInterceptorRef(newPackage, packageElement); // load the default class ref for this package loadDefaultClassRef(newPackage, packageElement); // load the global result list for this package loadGlobalResults(newPackage, packageElement); // load the global exception handler list for this package loadGobalExceptionMappings(newPackage, packageElement); // get actions NodeList actionList = packageElement.getElementsByTagName("action"); for (int i = 0; i < actionList.getLength(); i++) { Element actionElement = (Element) actionList.item(i); addAction(actionElement, newPackage); } // load the default action reference for this package loadDefaultActionRef(newPackage, packageElement); PackageConfig cfg = newPackage.build(); configuration.addPackageConfig(cfg.getName(), cfg); return cfg; }//loadConfigurationFiles解析读取xml中的内容 private List<Document> loadConfigurationFiles(String fileName, Element includeElement) { ... //通过DomHelper调用SAX进行解析xml doc = DomHelper.parse(in, dtdMappings); ... Element rootElement = doc.getDocumentElement(); NodeList children = rootElement.getChildNodes(); int childSize = children.getLength(); for (int i = 0; i < childSize; i++) { Node childNode = children.item(i); if (childNode instanceof Element) { Element child = (Element) childNode; final String nodeName = child.getNodeName(); if ("include".equals(nodeName)) { String includeFileName = child.getAttribute("file"); //解析每个action配置是，对于include文件可以使用通配符*来进行配置 //如Struts.xml中可配置成<include file="actions_*.xml"/> if (includeFileName.indexOf('*') != -1) { ClassPathFinder wildcardFinder = new ClassPathFinder(); wildcardFinder.setPattern(includeFileName); Vector<String> wildcardMatches = wildcardFinder.findMatches(); for (String match : wildcardMatches) { //递归Load子file中的<include/> docs.addAll(loadConfigurationFiles(match, child)); } } else { docs.addAll(loadConfigurationFiles(includeFileName, child)); } } } } docs.add(doc); loadedFileUrls.add(url.toString()); ... return docs; }

1 楼 nianien 2011-03-15 你好,我怎么找不到哪个地方有写加载struts.properties文件的代码段呢?
