Ajax call with file upload and receive in Spring MVC

user5685187

I want to upload a file through Ajax, and to receive in Spring MVC. Here is my client side code:

<form id="import-form" action="" method="post" enctpye="multipart/form-data">
    <input type="file" id="import" style="display:none;" />
</form>


$(document).ajaxSend(function(e, xhr, options){
    var header = "<#if _csrf??>${_csrf.headerName}</#if>";
    var token = "<#if _csrf??>${_csrf.token}</#if>";
    xhr.setRequestHeader(header, token);
});


$("#import").on("change", function(){

    var path = $(this).val();

    if(path == null || path == ""){
        alert("선택된 파일이 없습니다.");
        return;
    }

    var formTag = $("#import-form")[0];
    var formData = new FormData(formTag);
    formData.append("file", $(this)[0].files[0]);

    $.ajax({
        url: managerRunner.importUrl,
        processData:null,
        data:formData,
        type:"post",
        dataType:"json",

        success:function(data){
            console.log(data);
        },
        error: function(jqxhr, textStatus, errThrown){
            console.log(textStatus);
            console.log(errThrown);
        }
    });
});

And here is the server side code:

@RequestMapping(value="/import-cheat", method=RequestMethod.POST)
    @ResponseBody
    public List<CheatImported> importCheats(@RequestParam("file") MultipartFile cheats) throws IllegalStateException, IOException{
        String path = getFileName(cheats);
        File file = new File(path);
        cheats.transferTo(file);

        try{
            return importService.importJsonFile(path);
        }catch(FileNotFoundException e){
            return null;
        }catch(ParseException e){
            return null;
        }
    }

In this code, I do not care of the business logic importService.importJsonFile(). I just want to upload a file successfully to the server. but there is an exception when trying to upload any file.

In this exception, it says it is not multipart request. So I added encoding type multipart/form-data.

$.ajax({
    url: managerRunner.importUrl,
    processData:null,
    data:formData,
    type:"post",
    dataType:"json",
    contentType:"multipart/form-data"
    success:function(data){
        console.log(data);
    },
    error: function(jqxhr, textStatus, errThrown){
        console.log(textStatus);
        console.log(errThrown);
    }
});

But even it throws the same error when trying to upload. Why does the exception come up ?

You need to add some extra configuration to your ajax call. In order for it to work, in my case I had to add contentType: false, cache: false and processData: false, in order to be able to send multipart files.

$.ajax({
    url: managerRunner.importUrl,
    data:formData,
    type:"post",

    // Tell jQuery not to process data or not to worry about content-type
    // You *must* include these options in order to send MultipartFile objects
    cache: false,
    contentType: false,
    processData: false,
    method: 'POST',
    type: 'POST',

    success:function(data){
        console.log(data);
    },
    error: function(jqxhr, textStatus, errThrown){
        console.log(textStatus);
        console.log(errThrown);
    }
});

Everything else is configured as intended, so it should work with those changes.
