Question

我似乎无法从此JSP页面生成PDF报告。虽然我能够以.pdf格式生成表单，但无法在Adobe Reader中打开。

<%

//response.setCharacterEncoding("utf-8");
//response.setHeader("Content-Transfer-Encoding", "binary");
//response.setHeader("Content-Type", "application/pdf");
response.setContentType("application/pdf");
response.setHeader("content-disposition", "attachment;filename=Donation Report.pdf");

Answer 1

您无法在页面上混合两种mimetypes，就像您尝试做的那样。

取出所有HTML。经过这两行

response.setContentType("application/pdf");
response.setHeader("content-disposition", "attachment;filename=Donation Report.pdf");

所有应该做的就是打印出PDF文件的字节。您可能必须在servlet中执行此操作，因为在JSP中尝试执行此操作通常会收到response.getOutputStream（）已被调用的错误。

行

response.setHeader("content-disposition", "attachment;filename=Donation Report.pdf");

除了告诉浏览器之后您要打印的文件的文件名。它不会去取PDF本身。您必须打开PDF，将其读入字节数组，然后将其打印到response.getOutputStream（）
