我从上传文件开始使用上传文件上传,然后从上传文件中使用Apache tika顶部提取content,metadata并应用,但是会出现一些错误

看一下我的playframework控制器代码:

public static Result upload() {
        MultipartFormData body = request().body().asMultipartFormData();
        FilePart picture = body.getFile("doc");
        if (picture != null) {

            String fileName = picture.getFilename();
            int eof = fileName.lastIndexOf('.');
            String ext = fileName.substring(eof + 1);

            file = picture.getFile();

            InputStream is;
            try {
                is = new FileInputStream(file);
            } catch (FileNotFoundException e) {

                e.printStackTrace();
            }
            Parser ps=new AutoDetectParser();

            BodyContentHandler bch=new BodyContentHandler();

            Metadata metadata=new Metadata();

            try {
                ps.parse(is, bch, metadata, new ParseContext());
            } catch (IOException | SAXException | TikaException e) {

                e.printStackTrace();
            }

            String sw=bch.toString();


            return ok(sw+" entity extracted and saved" + ext);
      }else {
        flash("error", "Missing file");
        return redirect(routes.Application.index());
    }


但是当我运行此Web应用程序时,我正在使用commands

rahul@inext:~/playframwrk apps/EntWebPrj$ play
        [info] Loading project definition from /home/rahul/playframwrk apps/EntWebPrj/project

它给出了错误:

如果您想看到完整的错误,请full error

和一些错误是:

我添加了tika jar文件。

给我一些想法来解决此问题。

最佳答案

可以通过两种方式向Playframework添加依赖项:


非托管依赖项:直接将jar添加到项目根目录的/ lib文件夹中,然后重新启动播放应用程序。
托管依赖项:如以下示例所示,将jar添加到build.sbt文件:

val appDependencies = Seq(
    jdbc, cache,
    "org.apache.tika" % "tika" % "0.3"
)
