之前上传文件都是没有问题的，不知道为啥出现这样的问题：Could not parse multipart servlet request; nested exception is org.apache.commons.fileupload.FileUploadException: Input length = 1？
前端是这样的：
<form enctype="multipart/form-data" id="batchUpload" action="" method="post" class="form-horizontal">
<table>
<tr>
<td >
<input type="file" name="file" style="width:0px;height:0px;" id="uploadEventFile">
<input id="uploadEventPath" disabled="disabled" type="text" placeholder="请选择excel表" style="border: 1px solid #e6e6e6; height: 115px;width: 400px;" >
</td>
</tr>
<tr>
<td align="center">
<cui:button label="选择文件" id="uploadEventBtn" componentCls="btn-primary" style="height:40px;width :185px" type="button" />
<cui:button label="上传文件" type="button" componentCls="btn-primary" style="height:40px;width :183px" onClick="uploadBtn()" />
</td>
</tr>
</table>
</form>
js:
$(function(){
//模拟上传excel
$("#uploadEventBtn").unbind("click").bind("click",function(){
$("#uploadEventFile").click();
});
$("#uploadEventFile").bind("change",function(){
$("#uploadEventPath").attr("value",$("#uploadEventFile").val());
})
});
//点击上传按钮
function uploadBtn(){
debugger;
var uploadEventFile = $("#uploadEventFile").val();
if(uploadEventFile == ''){
$.message({message:"请选择excel,再上传！", cls:"waring"});
}else if(uploadEventFile.lastIndexOf(".xls")<0){//可判断以.xls和.xlsx结尾的excel
$.message({message:"只能上传Excel文件！", cls:"waring"});
}else{
debugger;
var formData = new FormData($("#batchUpload")[0]);
var ul = '${ctx}/zbgl/zbbp/validateDutydate';
$.loading({text:"正在处理中，请稍后..."});
$.ajax({
url: ul,
type: "POST",
data:formData,
dataType: "json",
processData: false, // 告诉jQuery不要去处理发送的数据
contentType: false, // 告诉jQuery不要去设置Content-Type请求头
success: function (data) {
debugger;
if(data.code == "1"){
$.loading("hide");
$.message({message:data.msg, cls:"waring"});
}else if(data.code == "300"){
$.loading("hide");
$.message({message:data.msg, cls:"waring"});
}else if(data.code == "500"){
$.loading("hide");
$.message({message:"操作失败！", cls:"waring"});
} else if(data.code == "200") {
}
});
}
};
controller层：
@RequestMapping(value = "/validateDutydate")
@ResponseBody
@Logger(action = "获取", logger = "获取传入的excal文件", model = "值班编排")
public Map<String, Object> validateDutydate(MultipartFile file, HttpServletRequest request, HttpServletResponse response) {
Map<String, Object> map = new HashMap<>();
try {
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
// 获取传入文件
InputStream inputStream = file.getInputStream();
zbbpService.validateDutydate(inputStream);
map.put("code", 200);
} catch (AlreadyHasDutyListOnDutyDayException duty) {
duty.printStackTrace();
map.put("code", 1);
map.put("msg", duty.getMessage());
} catch (IOException e) {
e.printStackTrace();
map.put("code", 300);
map.put("msg", "文件读取异常！");
} catch (Exception e) {
e.printStackTrace();
map.put("code", 500);
}
return map;
}
后端一直进不去，这是什么问题？
