<div> <label>图片</label> <div> <input type="file" multiple data-browse-on-zone-click="true" accept="image/*" /> <input th:value="${record.picUrls}" type="hidden">//获取上传的图片路径，$("#filesInput").val()获取不到，用隐藏的input来获取 </div> </div>
引入js和css文件
<link href="https://www.jb51.net/ajax/libs/bootstrap-fileinput/fileinput.css" type="text/css"/> <script th:src="@{/js/jquery.min.js}"></script> <script th:src="@{/js/bootstrap.min.js}"></script> <script th:src="@{/ajax/libs/bootstrap-fileinput/fileinput.js}"></script>
