thymeleaf，bootstrap-fileinput 多文件上传

组件遍历上传

一、前端

html 复制代码

<!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"/>

<body class="white-bg">
    <div class="wrapper wrapper-content animated fadeInRight ibox-content">

                    <div class="file-loading">

            </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({

        });

        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();

                        continue;

                }

            })
            $(this).fileinput('_initFileActions');
        });
    </script>
</body>
</html>

二、后端

java 复制代码

@Controller
@RequestMapping("/common")
public class CommonController
{
    private static final Logger log = LoggerFactory.getLogger(CommonController.class);

    @Autowired
    private ServerConfig serverConfig;
    

    /**
     * 通用上传请求（单个）
     */
    @PostMapping("/upload")
    @ResponseBody
    public 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());
        }
    }
}

java 复制代码

@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();
    }
}
