在JSP中如何实现“网页直接浏览PDF和WORD文件”
在JSP中如何实现“网页直接浏览PDF和WORD文件”
[解决办法]
这是我的代码，供参考
public ActionForward read(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
// TODO Auto-generated method stub
String filePath=(String)request.getParameter("url");
File f = new File(filePath);
String filename = f.getName();
if(!f.exists()){
response.sendError(404,"没有您要打开的文件");
return null;
}
BufferedInputStream br = new BufferedInputStream(new FileInputStream(f));
byte[] buf = new byte[1024];
int len = 0;
response.reset();//非常重要
//在线打开方式
URL u = new URL("file://"+filePath);
response.setContentType(u.openConnection().getContentType());
response.setHeader("Content-Disposition", "online;filename=" + new String(filename.getBytes(), "ISO-8859-1"));//保证显示中文;
//文件名应该编码成UTF-8
OutputStream out = response.getOutputStream();
while((len = br.read(buf)) >0)
out.write(buf,0,len);
br.close();
out.close();
return null;
}
