freemarker对数字格式的处理

场景，导出word xml时，数字都带有逗号（实际情况要去掉）

如图：

 修改，需要如下红色代码设置下

private void generateWordDocument(Map<String, Object> rootMap, OutputStream out) throws Exception {
    String filePath = XhxhzjmQzController.class.getClassLoader().getResource("/").getPath()
          + File.separator + "template" + File.separator + "xhxhzjmqz";

    Configuration cfg = new Configuration(Configuration.VERSION_2_3_22);
    cfg.setDefaultEncoding("UTF-8");
    cfg.setDirectoryForTemplateLoading(new File(filePath));
    cfg.setNumberFormat("#");

    Template temp = cfg.getTemplate("xhbgyl.ftl", "utf-8");
    try (Writer writer = new OutputStreamWriter(out, "UTF-8")) {
       temp.process(rootMap, writer);
    }
}
