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>
