第一步：下載wkhtmktopdf軟件，安裝在指定的目錄，如：C:\htmlToPdf\wkhtmltopdf，

第二步：把安裝好的wkhtmltopdf文件目錄加到環(huán)境變量Path路徑中，

public void convertFile(){

HttpURLConnection con = null;

URL url = null;

Process p = null;

String cmd = "html2pdf";//安裝文件目錄名，此名是在linux下的，其它可以自己加目錄

try {

String sessionid = Struts2Util.getRequest().getSession().getId();

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

url = new URL(

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

con = (HttpURLConnection) url.openConnection();

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

con.connect();

int size = 0;

byte[] buf = new byte[1024];

BufferedInputStream bis = new BufferedInputStream(con

.getInputStream());

StringBuffer strb = new StringBuffer();

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

strb.append(new String(buf, 0, size));

}

FileWriter writer = null;

File file = new File("/tmp/quote_print.html");

writer = new FileWriter(file);

writer.write(strb.toString());

writer.flush();

writer.close();

ProcessBuilder pb = new ProcessBuilder(cmd, "/tmp/quote_print.html",

"/tmp/quote_print.pdf");//使用插件進(jìn)行轉(zhuǎn)換

pb.redirectErrorStream(true);

p = pb.start();

InputStreamReader ir = new InputStreamReader(p.getInputStream());

LineNumberReader input = new LineNumberReader(ir);

String line;

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

System.out.println(line);

}

// 提示下載

HttpServletResponse response = Struts2Util.getResponse();

response.setContentType("APPLICATION/DOWNLOAD");

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

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

java.io.OutputStream os = response.getOutputStream();

java.io.FileInputStream fis = new java.io.FileInputStream(

"/tmp/quote_print.pdf");

byte[] b = new byte[1024];

int i = 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 (Exception e) {

e.printStackTrace();

throw new RuntimeException(e);

}finally{

if(p!=null){

p.destroy();

}

}

}
