SpringMvc代码

jar包

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>
