java通过FreeMarker模板生成Excel文件之.ftl模板制作

关于怎么通过freemarker模板生成excel的文章很多，关键点在于怎么制作模板文件.ftl

网上的办法是：

（1）把Excel模板的格式调好，另存为xml文件

（2）新建一个.ftl文件，把xml文件内容copy进去，把变量换成FreeMarker的插值

  当然可行，但是这样制作的.ftl文件偏大，可读性很低

  

 我是这样制作的，直接写HTML标签

<table>
    <thead>
        <tr>
            <td>资产端简称</td>
            <td>放款金额(元)</td>
            <td>账单月份</td>
            <td>UZY服务费(元)</td>
            <td>账单状态</td>
        </tr>
    </thead>

    <tbody>
    <#list dataList as data>
        <tr>
            <td>${(data.assetName)!""}</td>
            <td>${(data.loanAmount?string('0.00'))!""}</td>
            <td>${(data.billMonth)!""}</td>
            <td>${(data.uzyServiceFee?string('0.00'))!""}</td>
            <td>${(data.statusName)!""}</td>
        </tr>
    </#list>
    </tbody>
</table>
简单吧，效果如下

后台部分代码：

private void exportToXls(String templateName, String fileName, Map<String, Object> dataMap, HttpServletResponse response) {
    Configuration configuration = new Configuration();
    configuration.setEncoding(Locale.CHINA, "UTF-8");
    configuration.setDefaultEncoding("UTF-8");
    configuration.setClassForTemplateLoading(this.getClass(), "/templates");
    String downloadFileName;
    try {
        downloadFileName = new String(fileName.getBytes("UTF-8"), "ISO8859-1");
    } catch (UnsupportedEncodingException e) {
        logger.warn("encode error", e);
        downloadFileName = DateUtil.format(new Date());
    }
    response.setContentType("application/ms-excel");
    response.setCharacterEncoding("UTF-8");
    response.setHeader("Content-disposition", "attachment; filename=" + downloadFileName + ".xls");
    try {
        Template template = configuration.getTemplate(templateName);
        template.process(dataMap, response.getWriter());
    } catch (Exception e) {
        logger.warn("export report error", e);
    }
}
