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")@ResponseBodypublic 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());    }}效果图：
