        configuration.setClassForTemplateLoading(FreemarkerExample.class, "/templates");

        try {
            // 获取模板对象
            Template template = configuration.getTemplate("example.ftl");

            // 创建数据模型
            Map<String, Object> dataModel = new HashMap<>();

            // 处理模板
            StringWriter writer = new StringWriter();
            template.process(dataModel, writer);

            // 输出结果
            System.out.println(writer.toString());

    }
}

<ul>
  <#list items as item>
    <li>${item}</li><#if item_has_next>\t</#if>
  </#list>
</ul>
