}
}
} catch (exception e) {

}

}
保存到本地
// copy file
public boolean copyfile (multipartfile tempfile, string filepath) {
boolean res = false;
try {
file file = new file(filepath);
if (!file.getparentfile().exists()) {
file.getparentfile().mkdirs();
}
// 将文件拷贝到当前目录下
tempfile.transferto(file);
res = true;
} catch (exception e) {
log.info("copyfile>>>>异常:{}", e.tostring());
}
return res;
}
angularjs代码
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<script src="https://cdn.static.runoob.com/libs/angular.js/1.4.6/angular.min.js"></script>
</head>
<body>
<div ng-app="myapp" ng-controller="uploadctrl">
<p><input type="file" multiple="multiple" name="files"></p>
<p><input type="text" name="id" ng-model="id"></p>
<p><input type="button" value="提交" ng-click="submit()"></p>
</div>
<script>
var app = angular.module('myapp', []);
app.controller('uploadctrl', ["$scope", "$http", function($scope, $http) {
$scope.submit = function () {
var fd = new formdata();
var files = document.queryselector('input[name="files"]').files;
for (var i=0; i<files.length; i++) {
fd.append("files", files[i]);
}
fd.append("id", $scope.id);
$http({
method:'post',
url : '/project/api/v1/upload',
data: fd,
headers: {'content-type':undefined},
transformrequest: angular.identity
}).success(function (response) {
console.log(response.data);
}).error(function () {
});
}
}]);
</script>
</body>
</html>
form表单提交
<form action="/project/api/v1/upload" method="post" enctype="multipart/form-data"> <p><input type="text" name="id" /></p> <p><input type="file" multiple="multiple" id="files" name="files" /></p> <p><input type="submit" value="submit" /></p> </form>
