我已经使用<ui:include>
. 在 JSP 页面中,我能够获取 PDF,但它将内容显示为纯文本。这是如何引起的,我该如何解决?
JSP 页面:
<html>
<%@page import="java.io.File"%>
<%@page import="java.io.*"%>
<body>
<%
response.reset();
File file = new File(
"D:\\TNWRD_Documents\\Knowladge_Base\\Financial_and_Administrative_powers.pdf");
response.setHeader("Content-Type", "application/pdf");
response.setHeader("Content-Disposition","inline;filename=Saba_PhBill.pdf");
response.setContentLength((int)file.length());
//OPen an input stream to the file and post the file contents thru the
//servlet output stream to the browser
FileInputStream in = new FileInputStream(file);
ServletOutputStream outs = response.getOutputStream();
response.setContentLength(in.available());
byte[] buf = new byte[8192];
int c=0;
try {
while ((c = in.read(buf, 0, buf.length)) > 0)
{
//System.out.println("size:"+c);
outs.write(buf, 0, c);
}
} catch (IOException ioe) {
ioe.printStackTrace(System.out);
} finally {
outs.flush();
outs.close();
in.close();
}
%>
</body>
</html>
