java - 通过 servlet 发送字节，得到 "HTTP method GET is not supported by this URL"

Question

我有以下代码...

  @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        super.doGet(req, resp);
        final int idValue = Integer.parseInt(req.getParameter("id"));
        final ProjectRunEntity projectRunEntity = projectDataService.findProjectRunEntity(idValue);
        try {
            final byte[] documentAsBytes = wordFileGenerationService.getDocumentAsBytes(projectRunEntity);
            resp.setContentType("application/msword");
            resp.setHeader("Content-Disposition", "inline; filename=example.doc;");
            final ServletOutputStream out = resp.getOutputStream();
            out.write(documentAsBytes);
            out.flush();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

它获取一些恰好是 word 文档的字节并将它们写入 servlet 响应。出于某种原因，当我点击 url 时，我在浏览器中收到以下消息...

"HTTP Status 405 - HTTP method GET is not supported by this URL"

我在 Tomcat 6 上。有什么想法吗？我知道我的调试器没有任何问题，正在将字节写入响应的输出流。

我猜这个错误是由默认的 doGet 实现抛出的(当你调用 super.doGet(req, resp) 时)。
