dlundy / wkhtmltopdf.java
Last active December 4, 2018 07:48
Quickie Java pipe out to wkhtmltopdf to create a pdf from a string with html
public byte[] getPdf(String html) {
byte[] results = null;
try {
// For piping in and out, we need separate args for this for some reason
String[] command = {"/usr/local/bin/wkhtmltopdf", "-", "-"};
ProcessBuilder builder = new ProcessBuilder(command);
// this eats up stderr but prevents us from having to handle it ourselves
builder.redirectErrorStream(false);
Process process = builder.start();

@Autowired
ViewResolver viewResolver;
protected String renderViewToString(Model model, HttpServletRequest request, HttpServletResponse httpServletResponse, final String viewName)
{
final StringWriter html = new StringWriter();
View renderView = new View()
