火狐浏览器下载的是页面5

//下载的方法如下
public void sendToClient() throws Exception {
File file = null;
try {
FacesContext facesContext = FacesContext.getCurrentInstance();
ServletContext servletContext = (ServletContext) facesContext
.getExternalContext().getContext();
String filePath = (String) servletContext.getRealPath("/")
+ "dataCollector/WorkDBDownload";

String fileName = "WorkDB.Assets";
file = new File(filePath + "/download" + "_" + currentOrgan.getId()
+ "/" + fileName);
HttpServletResponse response = (HttpServletResponse) facesContext
.getExternalContext().getResponse();
response.setContentType("application/x-msdownload");
String header = RequestParam.getRequest().getHeader("User-Agent");
if (header.indexOf("MSIE") > 0) {
response.setHeader("Content-disposition",
"attachment;filename=" + fileName);
} else {
StringBuffer contentDisposition = new StringBuffer();
response.setHeader(
"Content-disposition",
new String(contentDisposition.toString().getBytes(
System.getProperty("file.encoding")),
"iso8859_1"));
}
FileInputStream fin = new FileInputStream(file);
byte[] b = new byte[(int) file.length()];
fin.read(b);
ServletOutputStream sos = response.getOutputStream();
sos.write(b);
sos.flush();
sos.close();
// 需要呼叫Complete
facesContext.responseComplete();
fin.close();
} catch (Exception e) {
throw new Exception("下载导出文件错误！", e);
}

}

采纳的答案

if (header.indexOf("MSIE") > 0) {
response.setHeader("Content-disposition",
"attachment;filename=" + fileName);
} else {
原因========
貌似都要设置
response.setHeader("Content-disposition",
"attachment;filename=" + fileName);

对，对于下载类型应该设置为：
