SpringMvc+Angularjs 实现多文件批量上传

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>
