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)@ResponseBodypublic 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>
