用response输出Pdf文件流后，页面显示：无法加载pdf文件

[这是feel的柑桔]

1、情况是这样子的：读取一个本地的pdf文件，然后再页面上显示这个pdf文件，就相当于pdf预览的功能。
遇到的问题是：通过在标题头的设置，从页面上下载的pdf无法让pdf阅读器读取显示，并且在页面查看就显示:"无法加载Pdf文件"。

页面展示时的图片：
2、代码是这样子的：
String filePath=SealAction.getPdfPath(); //pdf文件的绝对路径
File outFile = new File(filePath);
if (!outFile.exists()) {
this.setMsg("文件不存在");
return EMPTY;
} else {
response.setContentLength((int)outFile.length());
response.setCharacterEncoding("utf-8");
response.setHeader("Content-type", "application/pdf;charset=utf-8");
String filename = outFile.getName();
response.addHeader("Content-Disposition","attachment;filename=" + new String(filename.getBytes(),"utf-8"));
FileInputStream fli = null;
OutputStream out = null;
BufferedReader in = null;
Writer oWriter = null;
//以流的方式响应会页面
try {
fli = new FileInputStream(outFile);
out = response.getOutputStream();

in = new BufferedReader(new InputStreamReader(fli,"UTF-8"));
oWriter = new BufferedWriter(new OutputStreamWriter(out,"UTF-8"));

char[] b = new char[1024];
int i = 0;
while((i = in.read(b))!= -1)
{
oWriter.write(b, 0, i);
}

in.close();
oWriter.flush();
oWriter.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
try{
if(in != null){
in.close();
in = null;
}if(oWriter != null){
oWriter.close();
oWriter = null;
}
}catch(Exception e){
//不作任何处理
}
}
}


3、总的来说：问题是如何能在页面上显示出pdf呢？ 哪里错了呢？

[我自横刀香甜笑]

public void findPdf() throws IOException{ HttpServletResponse response = ServletActionContext.getResponse(); response.setContentType("application/pdf"); FileInputStream in = new FileInputStream(new File(“c:/测试.pdf”)); OutputStream out = response.getOutputStream(); byte[] b = new byte[512]; while ((in.read(b))!=-1) { out.write(b); } out.flush(); in.close(); out.close(); }

搞来搞去，发现你这样写的是最简单的，可行

好的，我都看了一下，你发的那些都是教如何创建pdf文件的，不太符合我题意，但是我还是感谢的你回答。

楼主，我跟你差不多导出pdf文件之后用2345看图王打开出现格式出现错误 response.setHeader("content-Type", "application/pdf"); // 下载文件的默认名称 SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd"); String fileName = "Classmate-" + new Date().getTime() + ".pdf"; response.setHeader("Content-Disposition", "attachment;filename="+ fileName); //设置中文 BaseFont bfChinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED); Font FontChinese = new Font(bfChinese, 12, Font.NORMAL); //创建一个document对象 Document document = new Document(); PdfWriter.getInstance(document, response.getOutputStream()); document.open(); document.addTitle("同学信息表"); //表头 PdfPTable tableS = new PdfPTable(6); tableS.addCell(new Paragraph("姓名",FontChinese)); tableS.addCell(new Paragraph("性别",FontChinese)); tableS.addCell(new Paragraph("电话",FontChinese)); tableS.addCell(new Paragraph("家庭地址",FontChinese)); tableS.addCell(new Paragraph("出生年月",FontChinese)); tableS.addCell(new Paragraph("个人喜好",FontChinese)); document.add(tableS);

我有一个类似预览pdf的功能，response响应本地pdf文件流后，页面全是乱码，看你的加了个 response.setContentType("application/pdf"); 解决了问题。
