html或其它文件转pdf弹出打开保存框

第一步：下载wkhtmktopdf软件，安装在指定的目录，如：C:\htmlToPdf\wkhtmltopdf，

第二步：把安装好的wkhtmltopdf文件目录加到环境变量Path路径中，

publicvoidconvertFile(){

HttpURLConnectioncon=null;

URLurl=null;

Processp=null;

Stringcmd="html2pdf";//安装文件目录名，此名是在linux下的，其它可以自己加目录

try{

Stringsessionid=Struts2Util.getRequest().getSession().getId();

System.out.println("sessionid=="+sessionid);

url=newURL(

"http://10.168.2.181:8080/scm/quote_extra!print.action");

con=(HttpURLConnection)url.openConnection();

con.setRequestProperty("Cookie","JSESSIONid="+sessionid);

con.connect();

intsize=0;

byte[]buf=newbyte[1024];

BufferedInputStreambis=newBufferedInputStream(con

.getInputStream());

StringBufferstrb=newStringBuffer();

while((size=bis.read(buf))!=-1){

strb.append(newString(buf,0,size));

}

FileWriterwriter=null;

Filefile=newFile("/tmp/quote_print.html");

writer=newFileWriter(file);

writer.write(strb.toString());

writer.flush();

writer.close();

ProcessBuilderpb=newProcessBuilder(cmd,"/tmp/quote_print.html",

"/tmp/quote_print.pdf");//使用插件进行转换

pb.redirectErrorStream(true);

p=pb.start();

InputStreamReaderir=newInputStreamReader(p.getInputStream());

LineNumberReaderinput=newLineNumberReader(ir);

Stringline;

while((line=input.readLine())!=null){

System.out.println(line);

}

//提示下载

HttpServletResponseresponse=Struts2Util.getResponse();

response.setContentType("APPLICATION/DOWNLOAD");

response.setHeader("Content-Disposition","attachment;filename="

+"PrintQuote"+(newRandom()).nextInt()+".pdf");//PackingSlip是文件名

java.io.OutputStreamos=response.getOutputStream();

"/tmp/quote_print.pdf");

byte[]b=newbyte[1024];

inti=0;

while((i=fis.read(b))>0){

os.write(b,0,i);

}

fis.close();

os.flush();

response.flushBuffer();

os.close();

bis.close();

con.disconnect();

}catch(Exceptione){

e.printStackTrace();

thrownewRuntimeException(e);

}finally{
