虽然我正在尝试将文件上传到球衣我正在接受以下异常，但有些人帮我解决。谢谢
Html doc： -
<div class="row form-group">
<div class="col-md-3 col-md-offset-1">
<input class="form-control" id="fileupload" type="file" name="uploadfile">
</div>
<div class="col-md-2">
<button type="button" class="form-control btn-sm btn-primary" id="file-upload">upload</button>
</div>
<div class="col-md-2">
<button type="button" class="form-control btn-sm btn-danger">cancel</button>
</div>
</div>

<div class="progress">

aria-valuemax="100" style="width: 20%">
<span class="sr-only">20% Complete</span>
</div>
</div>
</form>
</body>
</html>
Ajax： -
$(document).ready(function() {
$("#fileupload").click(function() {
$(this).change(function() {
var filename = $(this).val();
var ext = filename.split('.').pop().toLowerCase();
if(ext =='yaml'){
console.log(this.files[0]);
}else{
alert("."+ext+" is not vaild file extension");
$(this).val('');
}
});
});
$("#file-upload").click(function(){
var file = $('input[name="uploadfile"').get(0).files[0];
var formData = new FormData();
formData.append('uploadfile', file);
$.ajax({
url : 'http://localhost:8080/IDNS_Rule_Configuration/idns/idnsData/importYaml', //Server script to process data
type : 'POST',
data : formData,
cache : false,
contentType : 'multipart/form-data',
dataType : 'application/x-yaml',
processData : false,
success : function(data, textStatus, jqXHR) {
var userObj = JSON.parse(jqXHR.responseText);
alert(userObj);
},
error : function(jqXHR, textStatus, errorThrown) {
alert(textStatus);
}
});
});
});
Java代码： -
@POST
@Consumes("multipart/form-data")
@Produces(MediaType.TEXT_PLAIN)
@Path("/importYaml")
public void uploadFile(@FormDataParam("uploadfile") InputStream uploadedInputStream,
@FormDataParam("uploadfile") FormDataContentDisposition fileDetail) {
try (BufferedReader reader = new BufferedReader(new InputStreamReader(uploadedInputStream));) {
/* int numLines = 0;*/
String line;
while( (line = reader.readLine()) != null ) {
/*numLines++;*/
System.out.println(line);
}
/* return Response.ok(Integer.toString(numLines), "text/plain").build();*/
} catch (final Exception e) {
throw new WebApplicationException(e);
}
}
