String inputHtml = "/myfolder/output.html";
String outputPdf = "/myfolder/output.pdf";
PDFNet.initialize();
PDFDoc doc = new PDFDoc();
HTML2PDF converter = new HTML2PDF();
converter.setLandscape(false);
converter.setPaperSize(9);
converter.insertFromHtmlString(new String(Files.readAllBytes(Paths.get(inputHtml))));
if (converter.convert(doc)) {
    doc.initSecurityHandler();
    doc.save(outputPdf, SDFDoc.e_linearized, null);
} else {
    log.error("Conversion failed. HTTP Code: " + converter.getHTTPErrorCode() + "\n" + converter.getLog());
}

输出

很可能正在使用的临时文件夹存在一些读/写权限问题。

请尝试以下操作。

PDFNet.setTempPath(folder_that_you_know_your_process_can_read_write);
PDFNet.initialize();
