本文主要是介绍thymeleaf，bootstrap-fileinput 多文件上传，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
组件遍历上传
一、前端
<!DOCTYPE html>
<html lang="zh" xmlns:th="http://www.thymeleaf.org" >
<head><th:block th:include="include :: header('修改固定资产信息')" /><th:block th:include="include :: datetimepicker-css" /><th:block th:include="include :: bootstrap-fileinput-css"/>
</head>
<body class="white-bg"><div class="wrapper wrapper-content animated fadeInRight ibox-content"><form class="form-horizontal m" id="form-gdzcxx-edit" th:object="${bizGdzcxx}"><input name="gdzcxxId" th:field="*{gdzcxxId}" type="hidden"><div class="form-group"> <label class="col-sm-3 control-label is-required">资产名称：</label><div class="col-sm-8"><input name="zcmc" th:field="*{zcmc}" class="form-control" type="text" required></div></div><div class="form-group"> <label class="col-sm-3 control-label">资产型号：</label><div class="col-sm-8"><input name="zcxh" th:field="*{zcxh}" class="form-control" type="text"></div></div><div class="form-group"><label class="col-sm-3 control-label">资产照片：</label><div class="col-sm-8"><input type="text" name="zczp" th:field="*{zczp}"><div class="file-loading"><input class="form-control file-upload" id="zczp" name="file" type="file" multiple></div></div></div></form></div><th:block th:include="include :: footer" /><th:block th:include="include :: datetimepicker-js" /><th:block th:include="include :: bootstrap-fileinput-js"/><script th:inline="javascript">var prefix = ctx + "biz/gdzcxx";$("#form-gdzcxx-edit").validate({focusCleanup: true});function submitHandler() {if ($.validate.form()) {$.operate.save(prefix + "/edit", $('#form-gdzcxx-edit').serialize());}}$(".file-upload").each(function (i) {var val = $("input[name='" + this.id + "']").val();var preView = val.split(',');$(this).fileinput({'uploadUrl': ctx + 'common/upload',initialPreviewAsData: true,initialPreview: preView,maxFileCount: 10,maxFileSize: 1000,autoReplace: true}).on('fileuploaded', function (event, data, previewId, index) {//多文件上传后，将文件名路径用“,”拼接起来if(data.response.fileName){var filenames = data.response.fileName;var currentFilename = $("input[name='" + event.currentTarget.id + "']").val();if(currentFilename!=''){filenames = currentFilename +',' +filenames;}$("input[name='" + event.currentTarget.id + "']").val(filenames);}}).on('fileremoved', function (event, id, index) {var fileIndex = index.replace('init-','');var currentFilename = $("input[name='" + event.currentTarget.id + "']").val();var fileNames = currentFilename.split(',');var lastFileNames = '';for(var i in fileNames){if(i == parseInt(fileIndex)){continue;}lastFileNames += fileNames[i]+',';}lastFileNames = lastFileNames.split(',').slice(0,-1).join(',');$("input[name='" + event.currentTarget.id + "']").val(lastFileNames);})$(this).fileinput('_initFileActions');});</script>
</body>
</html>二、后端
@Controller
@RequestMapping("/common")
public class CommonController
{private static final Logger log = LoggerFactory.getLogger(CommonController.class);@Autowiredprivate ServerConfig serverConfig;/*** 通用上传请求（单个）*/@PostMapping("/upload")@ResponseBodypublic AjaxResult uploadFile(MultipartFile file) throws Exception{try{// 上传文件路径String filePath = "D:/upload";// 上传并返回新文件名称String fileName = FileUploadUtils.upload(filePath, file);String url = serverConfig.getUrl() + fileName;AjaxResult ajax = AjaxResult.success();ajax.put("url", url);ajax.put("fileName", fileName);ajax.put("newFileName", FileUtils.getName(fileName));ajax.put("originalFilename", file.getOriginalFilename());return ajax;}catch (Exception e){return AjaxResult.error(e.getMessage());}}
}@Component
public class ServerConfig
{/*** 获取完整的请求路径，包括：域名，端口，上下文访问路径* * @return 服务地址*/public String getUrl(){HttpServletRequest request = ServletUtils.getRequest();return getDomain(request);}public static String getDomain(HttpServletRequest request){StringBuffer url = request.getRequestURL();String contextPath = request.getServletContext().getContextPath();return url.delete(url.length() - request.getRequestURI().length(), url.length()).append(contextPath).toString();}
