创建word文档，将需要替换的内容用${XXX}替换。将文档另存为mht文件（mht文件支持html标签，而xml文件不支持），再另存为ftl文件。修改编码为UTF-8，去除{}内多余的标签代码

RichContent

String templateName = "test.ftl";
Map data = new HashMap<>();
data.put("author", "一路生花");
data.put("createTime", "2022-08-01");

//创建富⽂本
StringBuilder sb = new StringBuilder();
sb.append("");
String cont = "
1、降低风险。2、8月6日开业。3、合作布局。4、服务中心。5、综合性交易展厅。
";
cont = cont + "
";
sb.append(cont);
sb.append("");

RichContent richContent = new RichContent();
richContent.setHtml(sb.toString());
