示例代码

    private static void genPdf(String url,String pdfFilePath) throws IOException {
        String osName = System.getProperty("os.name").toUpperCase();
        log.info("osName:{}",osName);
        if(osName.contains("")){

        }
        List<String> pdfCommand = Arrays.asList(
                /*安装程序路径的bin文件夹下*/
                /*"chrome.exe --no-pdf-header-footer --headless --disable-gpu --no-sandbox --print-to-pdf="+pdfFilePath+" " +url*/
                "/usr/bin/google-chrome",

        for (int i = 0; i < pdfCommand.size(); i++) {
            String command =  pdfCommand.get(i);
            log.info("command:{}",command);

        }

        ProcessBuilder pb = new ProcessBuilder(pdfCommand);
        Process pdfProcess;
        int status;
        try {
            pdfProcess = pb.start();
            try(BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(pdfProcess.getInputStream(), StandardCharsets.UTF_8))){
                while (pdfProcess.isAlive()) {
                    while (bufferedReader.ready()) {
                        String line = bufferedReader.readLine();

                    }
                }

            }catch (InterruptedException e) {
                throw new RuntimeException("PDF generation failed");
            }
            //检测是否生成成功，如果成功则创建下载pdf的路径
            if(status==0) {

                log.info("生成pdf成功");
            }
        }
        catch (IOException ex) {
            ex.printStackTrace();
            log.info("ex:{}",ex.getCause());
            throw new RuntimeException("PDF转化失败");
        }
    }

注意事项:

注意事项1:软件一定要写绝对路径,配置了环境变量也不行;配置了环境变量只是保证在黑窗口不用输入绝对地址,但是java调用不行,必须输入绝对路径

注意事项2:多个参数,一个参数一行命令,且首尾不能有空格
