Question

我的目的是在视图中显示其方法使用注解进行注释的（项目）所有文件。

我成功获得了项目的所有文件名，但无法将资源转换为对象以测试其是否带有注释。

我有一个java.io.StreamCorruptedException: invalid stream header: 7061636B指向行ois = new ObjectInputStream(is);，我自己也无法解释。仅供参考，我已经尝试使用FileInputStream，但是得到了相同的结果。

这是我的代码：

    private boolean filenameIsAnnotated(IResource member) {
    // transform a IResource into an Object
    InputStream is = null;
    ObjectInputStream ois = null;
    Object object = null;
    try {
        is = ((IFile) member).getContents();
        File f = member.getLocation().toFile();
        is = new FileInputStream(f);
        ois = new ObjectInputStream(is);
        object = ois.readObject();
        if (is != null && ois != null) {
            // verify that one of the method is annotated
            for (Method m : object.getClass().getMethods()) {
                System.out.println(" method  " + m.getName());
                if (m.isAnnotationPresent(SPECIFICANNOTATION))
                    return true;
            }
        }
    } catch (IOException | ClassNotFoundException | CoreException e) {
        e.printStackTrace();
    } finally {
        if (is != null && ois != null) {
            try {
                is.close();
                ois.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
    return false;
}

以下是使用此方法的情况，以防万一：

    /**
 * Recursively, go thru all the hierarchy of folders to find one given folder
 * and return all of its files. A Container can be a IFolder, IProject or
 * IWorkspaceRoot
 */
private ArrayList<String> processContainer(IContainer container, String filesLocationFolder) {
    IResource[] members = null;
    try {
        members = container.members();
    } catch (CoreException e) {
        e.printStackTrace();
    }
    for (IResource member : members) {
        if (member instanceof IContainer) {
            processContainer((IContainer) member, filesLocationFolder);
        } else if (member instanceof IFile) {
            if (container instanceof IFolder) {
                if (member.getFileExtension().equals("java")) {
                    //test if the file is annotated 
                    if (filenameIsAnnotated(member))
                        fileList.add(member.getLocation().toFile().getName());
                }
            }
        }
    }
    return fileList;
}

和调用先例的方法：

private ArrayList<String> getFileList(String projectName, String filesLocationFolder) {
    // gets the workspace root
    IWorkspaceRoot currentRoot = ResourcesPlugin.getWorkspace().getRoot();
    IProject project = currentRoot.getProject(projectName);
    try {
        currentRoot.refreshLocal(IResource.DEPTH_INFINITE, null);
        project.refreshLocal(IResource.DEPTH_INFINITE, null);
    } catch (CoreException e) {
        e.printStackTrace();
    }
        // Find the annotated files, return a list
    ArrayList<String> list = processContainer(project, filesLocationFolder);
    return list;
}
