Javascript 如何使用spring mvc控制器通过ajax sumbit传递文件对象

我试图通过jqueryajaxsubmit传递文件对象。
JSP代码

<div id="import-file">
        <input type="file" id="file"/>
        <table>
        <tr><td><input type="radio" name="type" value="csv"></td><td>CSV File</td></tr>
        <tr><td><input type="radio" name="type" value="excel"></td><td>Excel spread sheet</td></tr>
        <tr><td><input type="radio" name="type" value="tab"></td><td>Tab delimited</td></tr>
        </table>
</div>

        var type = $($('input:radio:checked')[0]).val();
        var file = $("#file")[0].files[0];
        alert($("#file")[0].files[0].name);
        $.ajax({
            data :{
                "file" : file,
                "type" : type
            },
            type: "POST",
            url: "fileupload.htm",
            success: function(data){
                alert(data);
            },
            error:function(err){
                alert(err);
            }
        });

var formData = new FormData($('form')[0]);    
    console.log("form data "+formData);
    $.ajax({
        url: 'fileupload.htm',
        data: formData,
        processData: false,
        contentType: false,
        type: 'POST',
        success: function(data){
            alert(data);
        },
        error: function(err){
            alert(err);
        }
    });

<form action="fileupload.htm" method="post" enctype="multipart/form-data" name="fileinfo">
<input type="file" name="fileName" id="file"/>
</form>

最后是我的spring控制器代码：

        var type = $($('input:radio:checked')[0]).val();
        var file = $("#file")[0].files[0];
        alert($("#file")[0].files[0].name);
        $.ajax({
            data :{
                "file" : file,
                "type" : type
            },
            type: "POST",
            url: "fileupload.htm",
            success: function(data){
                alert(data);
            },
            error:function(err){
                alert(err);
            }
        });

@RequestMapping(value="fileupload.htm",method=RequestMethod.POST )
    public @ResponseBody String uploadFile(@RequestParam String type, @RequestParam("file") MultipartFile file){
        logger.info("file type : "+type + "file is "+file.toString());
        return "SUCCESS";
    }

我正在获取NS_NOINTERFACE:组件在我的firebug控制台中没有请求的接口[nsIDOMBlob.slice]错误。

我已经这样解决了它：

        var type = $($('input:radio:checked')[0]).val();
        var file = $("#file")[0].files[0];
        alert($("#file")[0].files[0].name);
        $.ajax({
            data :{
                "file" : file,
                "type" : type
            },
            type: "POST",
            url: "fileupload.htm",
            success: function(data){
                alert(data);
            },
            error:function(err){
                alert(err);
            }
        });

JavaScript代码

<div id="import-file">
        <input type="file" id="file"/>
        <table>
        <tr><td><input type="radio" name="type" value="csv"></td><td>CSV File</td></tr>
        <tr><td><input type="radio" name="type" value="excel"></td><td>Excel spread sheet</td></tr>
        <tr><td><input type="radio" name="type" value="tab"></td><td>Tab delimited</td></tr>
        </table>
</div>

        var type = $($('input:radio:checked')[0]).val();
        var file = $("#file")[0].files[0];
        alert($("#file")[0].files[0].name);
        $.ajax({
            data :{
                "file" : file,
                "type" : type
            },
            type: "POST",
            url: "fileupload.htm",
            success: function(data){
                alert(data);
            },
            error:function(err){
                alert(err);
            }
        });

var formData = new FormData($('form')[0]);    
    console.log("form data "+formData);
    $.ajax({
        url: 'fileupload.htm',
        data: formData,
        processData: false,
        contentType: false,
        type: 'POST',
        success: function(data){
            alert(data);
        },
        error: function(err){
            alert(err);
        }
    });

<form action="fileupload.htm" method="post" enctype="multipart/form-data" name="fileinfo">
<input type="file" name="fileName" id="file"/>
</form>

JSP代码

<div id="import-file">
        <input type="file" id="file"/>
        <table>

        var type = $($('input:radio:checked')[0]).val();
        var file = $("#file")[0].files[0];
        alert($("#file")[0].files[0].name);
        $.ajax({
            data :{
                "file" : file,
                "type" : type

            error:function(err){
                alert(err);
            }
        });

var formData = new FormData($('form')[0]);    
    console.log("form data "+formData);
    $.ajax({
        url: 'fileupload.htm',
        data: formData,

            alert(data);
        },
        error: function(err){
            alert(err);
        }
    });

<form action="fileupload.htm" method="post" enctype="multipart/form-data" name="fileinfo">
<input type="file" name="fileName" id="file"/>
</form>

希望它能对一些人有所帮助。

您必须立即传递formDatadata是formData现在您正在传递文件对象，但这不起作用，您需要传递文件本身，并且必须传递，因为您可以更正上述代码并将其作为答案发布。这将对我有所帮助

        var type = $($('input:radio:checked')[0]).val();
        var file = $("#file")[0].files[0];
        alert($("#file")[0].files[0].name);
        $.ajax({
            data :{
                "file" : file,
                "type" : type
            },
            type: "POST",
            url: "fileupload.htm",
            success: function(data){
                alert(data);
            },
            error:function(err){
                alert(err);
            }
        });
