在Wicket中拥有一个静态“子站点”（即：在Wicket中安装一个目录）

Question

我正在使用Wicket开发一个web应用程序。

虽然网站的大部分是通过wicket动态生成的，但我需要让网站的一部分成为一个正常的“静态”HTML网站。基本上是主网站中的一个小“子站点”，根本不由wicket管理，而是静态内容（html页面、css、图像）的集合。

这能做到吗？这个想法是“挂载”某个子路径以指向子站点，但我不知道这是否可能，因为mountresource()方法需要一个资源作为输入。

编辑：我需要一个解决方案，允许我直接在文件系统上修改静态html文件，这就是我试图通过Wicket“挂载一个目录”的原因。我不能简单地将页面放在我的webapp文件夹中，因为这样它们最终会在应用程序的WAR文件中，而且每次对静态页面的修改都需要完全部署。

有什么想法吗？

最后，我自己使用动态资源实现了这一点。我不是检票口的专家，所以出于某种原因，这可能是一个“糟糕”的解决方案，但它似乎有效。在这里发布代码，以便其他人可以在需要时使用：

我所做的是创建这个资源：

public class DirectoryResolverResource implements IResource {
    private static final long serialVersionUID = 1L;

    private File servedDirectory;
    private String urlPrefix;

    //served directory is the directory you want to mount as a static sub-site
    //urlPrefix is the mountpoint where you're going to mount this resource, without the leading "/". E.g.: if you mount your directory in "/help" so that the sub-site URL is www.yoursite.com/pages/help the urlPrefix value must be "help"
    public DirectoryResolverResource(File servedDirectory, String urlPrefix) {
        super();
        if (servedDirectory == null || !servedDirectory.isDirectory()) {
            throw new IllegalArgumentException("Directory is null or doesn't exist");
        }
        this.servedDirectory = servedDirectory;
        this.urlPrefix = urlPrefix;
    }

    @Override
    public void respond(Attributes attributes) {
        Url url = attributes.getRequest().getUrl();
        String subPath = "";
        try {
            //we decode the URL by reversing the percent-encoding, so that filenames are properly resolved
            subPath = URLDecoder.decode(url.toString(), "UTF-8");
        } catch (UnsupportedEncodingException e) {
            throw new AbortWithHttpErrorCodeException(HttpServletResponse.SC_BAD_REQUEST, "Encoding is invalid");
        }

        if (subPath.startsWith(urlPrefix)) {
            subPath = subPath.substring(urlPrefix.length());
        } else {
            throw new AbortWithHttpErrorCodeException(HttpServletResponse.SC_INTERNAL_SERVER_ERROR, "Url is invalid");
        }

        File file = new File(servedDirectory.getAbsolutePath() + (subPath.startsWith("/") ? "" : "/") + subPath);
        if (file.isDirectory()) {
            // In case of a directory, redirect to the path ending in "/", otherwise browsers will fail to resolve relative paths in the page
            if (!subPath.endsWith("/")) {
                throw new RedirectToUrlException("." + (subPath.isEmpty() ? "/" + urlPrefix : subPath) + "/", HttpServletResponse.SC_MOVED_PERMANENTLY);
            }
            // no specific file specified, try to return index.html
            file = new File(file.getAbsolutePath(), "index.html");
        }
        if (!file.exists() || file.isDirectory()) {
            // file not found
            throw new AbortWithHttpErrorCodeException(HttpServletResponse.SC_NOT_FOUND, "Resource not found");
        }

        if (!FSManager.isInSubDirectory(servedDirectory, file)) {
            // Security check: user is trying to escape the served directory via a non-canonical path
            throw new AbortWithHttpErrorCodeException(HttpServletResponse.SC_FORBIDDEN, "Access to this resource is forbidden");
        }

        // Serve the file
        FileResourceStream fileResourceStream = new FileResourceStream(file);
        ResourceStreamResource resource = new ResourceStreamResource(fileResourceStream);
        resource.respond(attributes);
    }

}

您可以像这样挂载此资源：

mountResource("/help", new ResourceReference("helpres") {
                private static final long serialVersionUID = 1L;

                @Override
                public IResource getResource() {
                    return new DirectoryResolverResource(helpDir, "help");
                }
            });

希望这对某人有帮助。如有任何改进/评论/更正/建设性的批评，不胜感激！

注意:isinsubdirectory()方法只检查文件是否在某个目录树中。我不会让您厌烦细节，您可以在这里找到这样的方法的实现：检查文件是否在（子）目录中
