前端：

<style type="text/css"> #detailTbody tr:hover { background: #fff; } .layui-form-label { width: 110px; } .uploader-list { margin-left: -15px; } .uploader-list .info { position: relative; margin-top: -25px; background-color: black; color: white; filter: alpha(Opacity=80); -moz-opacity: 0.5; opacity: 0.5; width: 100px; height: 25px; text-align: center; display: none; } .uploader-list .handle { position: relative; background-color: #ff6a00; color: white; filter: alpha(Opacity=80); -moz-opacity: 0.5; width: 100px; text-align: right; height: 18px; margin-bottom: -18px; display: none; } .uploader-list .handle span { margin-right: 5px; } .uploader-list .handle span:hover { cursor: pointer; } .uploader-list .file-iteme { margin: 12px 0 0 15px; padding: 1px; float: left; } </style> <div class="layui-upload"> <button type="button" class="layui-btn layui-btn-warm" id="test2">单据上传（可上传多张）</button> <blockquote class="layui-elem-quote layui-quote-nm" style="margin-top: 10px;width: 88%"> 预览图： <div class="layui-upload-list uploader-list" style="overflow: auto;" id="uploader-list"> <div id="" class="file-iteme" th:each="img :${data.orderVoucher}"> <div class="handle"><i class="layui-icon" style="color: white;margin-right: 40%">&#xe640;</i> </div> <img th:src="${img}" alt="单据" width="100" height="100" onclick="showBig(this)"> </div> </div> </blockquote> </div>

js：

layui.use(['form', 'layer', 'laydate', 'upload'], function () { $ = layui.jquery; var form = layui.form, layer = layui.layer, laydate = layui.laydate, upload = layui.upload; //多图片上传 upload.render({ elem: '#test2' , url: '/psi/order/uploadImg' , multiple: true , before: function (obj) { layer.msg('图片上传中...', { icon: 16, shade: 0.01, time: 0 }) } , done: function (res) { layer.close(layer.msg());//关闭上传提示窗口 //上传完毕 $('#uploader-list').append( '<div id="" class="file-iteme">' + '<div class="handle"> <i class="layui-icon" style="color: white ;margin-right: 40%">&#xe640;</i></div>' + '<img style="color: white;width: 100px;height: 100px" onclick="showBig(this)" src=' + res.url + ' >' + '</div>' ); } }); }); $(document).on("mouseenter mouseleave", ".file-iteme", function (event) { if (event.type === "mouseenter") { //鼠标悬浮 $(this).children(".info").fadeIn("fast"); $(this).children(".handle").fadeIn("fast"); } else if (event.type === "mouseleave") { //鼠标离开 $(this).children(".info").hide(); $(this).children(".handle").hide(); } }); $(document).on("click", ".file-iteme .handle", function(event){ $(this).parent().remove(); }) }) function showBig(obj) { var url = (obj.src); var index = layer.open({ type: 2, content: url, area: ['100%', '100%'], title: "单据", maxmin: true, closeBtn: 1 }); layer.full(index); }

controller层

@RequestMapping(value = "/uploadImg") @ResponseBody public Map<String,Object> uploadImg(MultipartFile file,HttpServletRequest request){ Map<String,Object> data = new HashMap<>(); String url = ""; if (!file.isEmpty()){ url = FileUploadUtil.saveImage(file,"orderVoucher",request); } data.put("url",url); return data; }

FileUploadUtil类

import org.springframework.web.multipart.MultipartFile; import javax.servlet." + requestFileUploadUtil.getServerName() + ":" + requestFileUploadUtil.getServerPort() + requestFileUploadUtil.getContextPath() + "/" + fileName + "/" + newFileName; return url; } }

yml虚拟路径配置

spring: resources: static-locations: classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/,file:${web.uploadPath} web: uploadPath: D:/svnproject/wechatprintingPicture
