html模板转pdf

工具方法：
public void createPdf(String htmlFilePath,SelectParamRequest paramRequest){
    if(paramRequest.getProductNamr() == null || paramRequest.getClassificationName() == null){
        System.out.println("有空值!!!");
        return;
    }
    //2.读取对应文件位置的html模板
    String htmlStr = PDFUtil.readHtmlFileByPath(htmlFilePath);
    //3.替换模板html中对应的元素
    htmlStr = changeHtmlTemp (htmlStr, paramRequest);
    //4.由于jsoup转换html时不是按照xhtml格式，因此需要jtidy进行一次转换
    htmlStr = PDFUtil.changeHtmlStrToXhtml(htmlStr);
    //5.生成对应路径下的pdf  生成pdf的路径，pdf名字
    PDFUtil.createPDFFileByHtmlStrInPath (htmlStr, paramRequest.getPDFPath(),paramRequest.getPDFName());
}

//2.读取对应文件位置的html模板

private static final String ENCODING="UTF-8";

    public static String readHtmlFileByPath (String htmlFilePath) {
        System.out.println("读取的模板路径："+ htmlFilePath);
        StringBuilder content = new StringBuilder ();
        String lineStr;
        InputStream fileInputStream = null;
        BufferedReader reader = null;
        try {
            //1.读取对应文件位置的html模板/static/temphtml/product.html
/*
            fileInputStream = new FileInputStream("E:\\workspace\\mytest\\alibaba\\src\\main\\resources\\static\\temphtml\\product.html");
*/
            fileInputStream = PDFUtil.class.getResourceAsStream (htmlFilePath);

            if (fileInputStream==null){
                System.out.println("!!!!!!!!!!!!!!!!!!!!!!!!1");
            }
            reader = new BufferedReader(new InputStreamReader(fileInputStream, ENCODING));
            while ((lineStr = reader.readLine()) != null) {
                content.append (lineStr);
                content.append("\n");
            }
        } catch (FileNotFoundException e) {
            throw new MyException("对应路径["+htmlFilePath+"]文件没找到",e.getMessage());

                }
            }
        }
        return content.toString ();
    }

//3.替换模板html中对应的元素

public String changeHtmlTemp (String htmlStr,SelectParamRequest paramRequest) {
    Document doc = Jsoup.parse (htmlStr);
    Element fenleinameEle = doc.getElementById ("fenlei");   //对应html标签的id值
    fenleinameEle.text (paramRequest.getClassificationName());

    chanpinEle.text(paramRequest.getProductNamr());
    Element xinghaoEle = doc.getElementById ("xinghao");
    xinghaoEle.text (paramRequest.getSpecifacationName());

    return doc.html();
}

public static String changeHtmlStrToXhtml(String htmlStr) {
    ByteArrayInputStream inStream = new ByteArrayInputStream(htmlStr.getBytes());
    ByteArrayOutputStream tidyOutStream = new ByteArrayOutputStream();
    Tidy tidy = new Tidy();
    tidy.setInputEncoding(ENCODING);
    tidy.setQuiet(true);
    tidy.setOutputEncoding(ENCODING);
    tidy.setShowWarnings(false); //不显示警告信息
    tidy.setIndentContent(true);//
    tidy.setSmartIndent(true);
    tidy.setIndentAttributes(false);
    tidy.setWraplen(1024); //多长换行
    //输出为xhtml
    tidy.setXHTML(true);
    tidy.setErrout(new PrintWriter(System.out));
    tidy.parse(inStream, tidyOutStream);
    return tidyOutStream.toString();
}

  public static void createPDFFileByHtmlStrInPath (String htmlStr, String storagePath,String pdfName){
        FileOutputStream fileOutputStream = null;
        try {
            File path = new File (storagePath);
            File file = new File(path,pdfName);

            if(! path.exists()) {
                path.mkdirs();
            }
            if ( !file.exists()) {
                if(!file.createNewFile ()){
                    throw new MyException("对应地址["+storagePath+"]文件创建失败");
                };
            }
            fileOutputStream = new FileOutputStream (file);
            ITextRenderer renderer = new ITextRenderer ();

            // 解决图片的相对路径问题,图片路径必须以file开头
//            renderer.getSharedContext().setBaseURL("file:/");
            renderer.layout ();
            renderer.createPDF (fileOutputStream);
        } catch (IOException e) {
            throw new MyException("向["+storagePath+"]路径生成pdf流错误",e.getMessage());
        } catch (DocumentException e) {
            throw new MyException("向["+storagePath+"]路径生成pdf文件流异常",e.getMessage());
        } finally {
            if (fileOutputStream != null) {

                    throw new MyException("向["+storagePath+"]路径生成pdfio关闭异常",e.getMessage());
                }
            }
        }
    }




html模板：注意要设置

<style type="text/css">
    .pdfBody{
        margin-left: 2em;
        font-size: 1.2em;
        font-family: SimSun;
        color: #666666;
        margin-top: 3em;
    }
</style>

<body >

    <div class="pdfBody">
        分类：<input type="text" id="fenlei"><br>

        产品：<input type="text" id="chanping"><br>

        型号：<input type="text" id="xinghao"><br>


        <div>添加型号tjsx</div>
    </div>

</body>

测试：

@RequestMapping("/createPdf.json")
@ResponseBody
public void createPdf(){
    SelectParamRequest paramRequest = new SelectParamRequest();
    paramRequest.setClassificationName("服装");
    paramRequest.setProductNamr("童装");
    paramRequest.setSpecifacationName("米老鼠");
    paramRequest =  initReceiptInfo(paramRequest);
    try {
        productService.createPdf("/static/temphtml/product.html",paramRequest);
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println(e.getCause().getLocalizedMessage());
    }
}
