java - 将文件保存到 Jersey API 中的服务器应用程序目录

Question

我正在使用 Jersey API 来使用多部分数据(照片)，并且我喜欢将其保存在服务器应用程序目录而不是任何其他驱动器中。我在D盘等其他驱动器中保存成功，但找不到将其保存到服务器应用程序目录中的方法。

@POST
@Path("uploadphoto")
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces("text/plain")
public String uploadNotices(@FormDataParam("file") InputStream uploadedInputStream) {
    String uploadedFileLocation = "d:/1.jpg";
    // save it
    try {
        writeToFile(uploadedInputStream, uploadedFileLocation);
    } catch(Exception e) {
        return "no";
    }
    return "yes";
}

// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream, String uploadedFileLocation) throws Exception {
    OutputStream out = new FileOutputStream(new File(uploadedFileLocation));
    int read = 0;
    byte[] bytes = new byte[1024];

    out = new FileOutputStream(new File(uploadedFileLocation));
    while ((read = uploadedInputStream.read(bytes)) != -1) {
        out.write(bytes, 0, read);
    }
    out.flush();
    out.close();
}

它解决了我的问题

@Context
private ServletContext context;

String filePath = context.getRealPath("images/");   
File file = new File(filePath);
