これは私のフォームです:
<form name="CIMtrek_Compliance_Daily_Shipments" enctype="multipart/form-data">
<input type="file" id="CIMtrek_comments" name="CIMtrek_comments" value="" />
<button id="upload" onclick="uploadCommentFile()">Upload</button>
</form>
これは jquery を使用した私の ajax 呼び出しです:
function uploadCommentFile(){
$("#upload").live("click", function() {
var file_data = $("#CIMtrek_comments").prop("files")[0]; // Getting the properties of file from file field
var form_data = new FormData(); // Creating object of FormData class
form_data.append("file", file_data) // Appending parameter named file with properties of file_field to form_data
//form_data.append("user_id", 123) // Adding extra parameters to form_data
$.ajax({
type: 'POST',
url: "/CIMtrek_Compliance_Daily_Shipments_FileUpload",
dataType: 'script',
cache: false,
contentType: false,
processData: false,
data: {
uploadFile: file_data
},
success: function (msg) {
global.getElementById("CIMtrek_uploadedFileName").innerHTML=msg;
}
})
})
}
これは私のスプリングコントローラーです：
@RequestMapping(value = "/CIMtrek_Compliance_Daily_Shipments_FileUpload", method = RequestMethod.POST)
public String createComments(@RequestParam("uploadFile") CommonsMultipartFile uploadItem,
HttpServletRequest request) {
String uploadedFileName="";
try {
MultipartFile file = uploadItem;
String fileName = null;
InputStream inputStream = null;
OutputStream outputStream = null;
if (file.getSize() > 0) {
inputStream = file.getInputStream();
System.out.println("size::" + file.getSize());
fileName = request.getRealPath("") + "/WEB-INF/resources/Attachment"+ file.getOriginalFilename();
System.out.println("path : "+request.getRealPath("") + "/WEB-INF/resources/Attachment");
outputStream = new FileOutputStream(fileName);
System.out.println("fileName:" + file.getOriginalFilename());
int readBytes = 0;
byte[] buffer = new byte[10000];
while ((readBytes = inputStream.read(buffer, 0, 10000)) != -1) {
outputStream.write(buffer, 0, readBytes);
}
outputStream.close();
inputStream.close();
}
uploadedFileName =file.getOriginalFilename();
} catch (Exception e) {
e.printStackTrace();
}
return uploadedFileName;
}
しかし、アップロードボタンをクリックすると、次の例外が発生します。
