ApplicationContext.xml

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="10000000" /> <!-- setting maximum upload size -->
</bean>

JSP:

<div data-ng-controller=''QuestionController''>
<form name="createChapForm" data-ng-submit="submitQue();" enctype="multipart/form-data" class="form-horizontal">
<div class="form-group">
<label class="control-label col-sm-3">Select Class * :</label>
<div class="col-sm-8">
<div class="col-sm-6">
<select data-ng-model=''class_id'' data-ng-init=''getClasses();'' data-ng-change=''getSubjectsClasswise(class_id);'' class="form-control" required>
<option value="">--SELECT--</option>
<option data-ng-repeat=''c in clss'' value="{{ c.class_id}}">{{ c.class_name}}</option>
</select>
</div>
</div>
</div>
<div class="form-group">

Controlador AngularJS:

$scope.submitQue = function() {
console.log(''file is '' ); console.dir(file.files[0]);
var URL =appURL+''/adm/doAddQuestion.do'';
var fd = new FormData();
fd.append(''file'', file.files[0]);
fd.append(''questionBean'', angular.toJson($scope.question, true));
$http.post(URL, fd, {
transformRequest : angular.identity,
headers : {
''Content-Type'' : undefined
}
}).success(function() {
console.log(''success'');
}).error(function() {
console.log(''error'');
});
}

Controlador Java:

@RequestMapping(value = "/doAddQuestion.do", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public @ResponseBody String saveUserDataAndFile(@RequestParam(value = "file") MultipartFile file, @RequestBody QuestionBean questionBean) {
System.out.println("output: "+questionBean.getQuestion_text());
// Im Still wotking on it
return "";
}

Answer 1

actualice su asignación de solicitud con el siguiente código:

 @RequestMapping(value = "/upload-file", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE)

Eliminará su excepción multiparte.

Answer 2

Agregue estos archivos .js donde ha agregado archivos angular.js angular-file-upload.js , angular-file-upload-shim.js , ng-file-upload.js , ng-file-upload-shim.js

Puede descargar desde este enlace Archivo Angular para Subir.

A continuación, agregue ngFileUpload,''angularFileUpload'' en angular.module consulte la línea siguiente.

angular.module(''formSubmit'', [ ''ngFileUpload'',
''angularFileUpload'', ''ui.router'' ]);

A continuación, agregue $upload en su controlador angular de esta manera.

app.controller(''FormSubmitController'', function($scope, $http, $upload)

Use $upload.upload lugar de $http.post en su código angular.

$upload.upload({
url : ''doAddQuestion.do'',
file : yourFile,
data : $scope.questionBean,
method : ''POST''
});

Cambia tu controlador de primavera.

@RequestMapping(value = "/doAddQuestion.do", method = RequestMethod.POST, headers = ("content-type=multipart/*"))
public @ResponseBody String saveUserDataAndFile(@RequestParam("file") MultipartFile file, QuestionBean questionBean) {
System.out.println("output: "+questionBean.getQuestion_text());
// Im Still wotking on it
return "";
}
