这篇文章将为大家详细讲解有关在SpringMvc项目中使用Angularjs 如何实现一个文件上传功能,文章内容质量较高,因此小编分享给大家做个参考,希望大家阅读完这篇文章后对相关知识有一定的了解。
SpringMvc代码
jar包
commons-fileupload
commons-io
spring-mvc.xml配置
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8" />
</bean>
Controller
@RequestMapping(value = "api/v1/upload", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Map upload (@RequestParam(value = "files") MultipartFile [] files,
@RequestParam(value = "id") String id,
HttpServletRequest request, HttpServletResponse response) {
Map res = new HashMap();
try {
log.info("upload>>>>>id:{}", id);
if (files!=null) {
for (MultipartFile file:files) {
log.info("filename:{}", file.getOriginalFilename());
}
}
} catch (Exception e) {
log.error("upload>>>>异常:{}", e.toString());
}
log.info("upload>>>>返回结果:{}", res);
return res;
}
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>
