1. 首先到官网把插件下载下来
git clone https://github.com/kartik-v/bootstrap-fileinput.git
2. 将文件导入到工程，在前端页面将插件引入
<link rel="stylesheet" href="${basePath}/resources/plugs/bootstrap-fileinput/css/fileinput.min.css"/>
<script src="${basePath}/resources/plugs/bootstrap-fileinput/js/fileinput.min.js"></script>
<script src="${basePath}/resources/plugs/bootstrap-fileinput/js/locales/zh.js"></script>
3. 导入界面
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">
<li class="fa fa-remove"></li>
</button>
<h5 class="modal-title">Excel文件上传</h5>
</div>
<div class="modal-body">
<form id="importFile" name="importFile" class="form-horizontal" method="post"
enctype="multipart/form-data">
<div class="box-body">
<div>
<label class="control-label">请选择要导入的Excel文件：</label>
<input id="excelFile" name="excelFile" class="file-loading" type="file" multiple accept=".xls,.xlsx"
> <br>
</div>
</div>
</form>
</div>
4. js处理
<script>
initUpload("excelFile", basePath + "/test/upload");
function initUpload(ctrlName, uploadUrl) {
var control = $(‘#‘ + ctrlName);
control.fileinput({
language: ‘zh‘, //设置语言
uploadUrl: uploadUrl, //上传的地址
uploadAsync: true, //默认异步上传
showCaption: true,//是否显示标题
showUpload: true, //是否显示上传按钮
browseClass: "btn btn-primary", //按钮样式
allowedFileExtensions: ["xls", "xlsx"], //接收的文件后缀
maxFileCount: 10,//最大上传文件数限制
previewFileIcon: ‘<i class="glyphicon glyphicon-file"></i>‘,
showPreview: true, //是否显示预览
previewFileIconSettings: {
‘docx‘: ‘<i ass="fa fa-file-word-o text-primary"></i>‘,
‘xlsx‘: ‘<i class="fa fa-file-excel-o text-success"></i>‘,
‘xls‘: ‘<i class="fa fa-file-excel-o text-success"></i>‘,
‘pptx‘: ‘<i class="fa fa-file-powerpoint-o text-danger"></i>‘,
‘jpg‘: ‘<i class="fa fa-file-photo-o text-warning"></i>‘,
‘pdf‘: ‘<i class="fa fa-file-archive-o text-muted"></i>‘,
‘zip‘: ‘<i class="fa fa-file-archive-o text-muted"></i>‘,
},
uploadExtraData: function () {
var extraValue = "test";
return {"excelType": extraValue};
}
});
}
$("#excelFile").on("fileuploaded", function (event, data, previewId, index) {
console.log(data);
if(data.response.success == true)
{
alert(data.files[index].name + "上传成功!");
//关闭
$(".close").click();
}
else{
alert(data.files[index].name + "上传失败!" + data.response.message);
//重置
$("#excelFile").fileinput("clear");
$("#excelFile").fileinput("reset");
$(‘#excelFile‘).fileinput(‘refresh‘);
$(‘#excelFile‘).fileinput(‘enable‘);
}
});
</script>
5. 后台接口
@RequestMapping(value = "/upload", method = RequestMethod.POST)
@ResponseBody
private Result importExcel(@RequestParam(value = "excelFile", required = false) MultipartFile file,HttpServletRequest request) {
try {
MultipartRequest multipartRequest=(MultipartRequest) request;
MultipartFile excelFile=multipartRequest.getFile("excelFile");
if(excelFile!=null){
List<List<String>> datas = ExcelUtil.readXls(excelFile.getInputStream());
//TODO: 读到的数据都在datas里面，根据实际业务逻辑做相应处理
// .............
if(datas!=null && datas.size()>0){
return new Result(true);
}
}else{
return new Result(false);
}
} catch (Exception e) {
return new Result(false,e.getMessage());
}
return new Result(false);
}
