_ [Seasar] S2Struts HotDeployでActionConfigのパス修正への道 (4)

前回の「HogeAction#setHogeService(HogeServuce hogeService)が動かなくて、HogeAction#setAaa_HogeService(HogeServuce hogeService)なら動く」ってのは、納得しました。HotDeployする時は、先にクラスを登録するわけじゃなく、後からコンポーネント名で探しに行くのでこうなるのか。HotDeployの仕組みの理解が足りない。

というわけで、クラスを探す機能を作れば上手く行くのかな。クラスを探す方法を探そう。

[追記] そんなわけでこんな感じでできた

• QualifiedInterfaceCentricSinglePackageCreator.java 抜粋
  • Filterは名前そのままの機能なので省略

 protected Class getTargetClass(String componentName) {
   String className = composeClassName(componentName);
   try {
     Class clazz = getTargetClass(ClassUtil.forName(className));
     return clazz;
   } catch (ClassNotFoundRuntimeException ce) {
     // 見つからない場合、探します。
     String shortClassName = StringUtil.capitalize(componentName);
     FileFilter filter = new ShortClassNameFileFilter(shortClassName);
     StringBuffer sb = new StringBuffer(100);
     super.concatName(sb, super.getRootPackageName());
     super.concatName(sb, super.getMiddlePackageName());
     String packageName = sb.toString().replaceAll("\\.", "/");
     ClassLoader loader = Thread.currentThread().getContextClassLoader();
     String classPath = "";
     try {
       Enumeration enumeration = loader.getResources(packageName);
       for (; enumeration != null && enumeration.hasMoreElements();) {
         URL classRootUrl = (URL)enumeration.nextElement();
         File root = new File(classRootUrl.getPath());
         classPath = findClassPath(root, filter);
         if (classPath != null) {
           classPath = classPath.replace(root.getPath(), "");
           classPath = classPath.replace(".class", "");
           classPath = classPath.replace(File.separator, ".");
           className = sb.toString() + classPath;
           return getTargetClass(ClassUtil.forName(className));
         }
       }
     } catch (IOException ie) {
       return null;
     }
   }
   return null;
 }

 private String findClassPath(File root, FileFilter filter)
     throws IOException {
   File[] files = root.listFiles(filter);
   if (files.length > 0) {
     return files[0].getPath();
   } else {
     files = root.listFiles(DirectoryFilter.INSTANCE);
     for (int i = 0; i < files.length; i++) {
       String classPath = findClassPath(files[i], filter);
       if (classPath != null) {
         return classPath;
       }
     }
   }
   return null;
 }

HogeAction#setHogeService(HogeServuce hogeService)で動きました。

次、extends AbstractHogeLogicしてる時の問題。これが解ければ動く気がする。

と、思ったら違うのもあった。
