springboot中怎么实现文件上传
第一步编写上传的前段页面
文档入库
第二步写对应的js页面
/** * @Name：historyStorageCtrl，井史数据入库 * @Date：2019-06-19 * @Author：huofenwei */(function (angular) { 'use strict'; angular.module('Lujing').controller('historyStorageCtrl', ['$scope', '$http', 'ToastService', '$compile', '$timeout', 'HttpService','$filter', function ($scope, $http, ToastService, $compile, $timeout, HttpService,$filter) { $scope.fileInvalid = false; var $fileInput = initFileInput("importFile", '/server/search/upload'); /** *初始化文件上传 */ function initFileInput(ctrlName, uploadUrl) { var control = $('#' + ctrlName); control.fileinput({ language: 'zh', uploadUrl: uploadUrl, //上传的地址 allowedFileExtensions: ['doc', 'docx', 'xls', 'xlsx', 'ppt', 'pptx', 'pdf', 'mp4', 'avi','wmv','asf','asx','rm','rmvb','3gp','mov','m4v','dat','mkv','flv','vob'], showUpload: true, //是否显示上传按钮 showCaption: true, //是否显示标题 showPreview: false, //是否显示预览区域 browseClass: "btn btn-primary", //按钮样式 previewFileIcon: "", }).on('fileuploaderror', fileuploaderror).on("fileuploaded", function (event, data, previewId, index) { // console.log(data);.on('fileselect', fileselect) $scope.$apply(function () { $scope.fileId = data.response.fileId; // 未执行 $scope.document.fileName = data.files[0].name; }); }).on("filecleared", function (event, data, msg) { $scope.$apply(function () { $scope.fileInvalid = false; }); }); return control; } /** * 清空输入框 */ function importClearFunc() { if ($fileInput) $fileInput.fileinput('clear'); $scope.fileInvalid = false; } /** * 文件上传错误 **/ function fileuploaderror(event, data, msg) { $scope.fileInvalid = true; $scope.$apply(); $('.modal-body .kv-upload-progress').css('display', 'none'); if (!(data.jqXHR.responseJSON)) { //文件类型验证错误 $('#fileError').html(msg); } else { //上传错误 console.log(data); var statusCode = data.jqXHR.responseJSON.message; var errorMsg = HTTP_ERROR_MAP['' + statusCode]; $('#fileError').html(errorMsg); } } /** * add 打开添加模态框 */ $scope.openAddModal = function () { $scope.document = {}; $scope.document.classificationId = 1; $scope.document.starGrade = 5; $timeout(importClearFunc); // openModeldialog(); }; /** * 表单验证 * @returns {boolean} */ function formVlidate() { if (!$scope.document.introduction) { return false; } if (!$scope.document.keyPackage) { return false; } return true; } /** * 提交表单信息 */ $scope.submitFileInfo = function () { if (!$scope.fileId) { // ToastService.alert("提示", "先上传文件，再提交表单", "info"); console.error("先上传文件，再提交表单"); return; } if (!formVlidate()) { // ToastService.alert("提示", "请填充表单", "info"); console.error("请填充表单"); return; } $scope.params = { 'introduction': $scope.document.introduction,//简介 'keyPackage': $scope.document.keyPackage,//可能查询的关键字 'starGrade': $scope.document.starGrade,//星级 'classificationId': $scope.document.classificationId,//文件的id 'filePath': $scope.fileId,//文件的路径 'docName': $scope.document.fileName,//文件的名字 'author':$scope.document.author, 'unit':$scope.document.unit, 'writeDate':$scope.document.writeDate?$scope.document.writeDate.format("yyyy-MM-dd hh:mm:ss"):$scope.document.writeDate, 'jh': $scope.document.jh, 'id': $scope.document.id }; HttpService.post("/server/search/submit", $scope.params).then(function (data) { $('#documentOprModal').modal('hide'); // $("#contTable").bootstrapTable('refresh'); console.error("提交文件信息成功"); }, function (response) { // ToastService.alert("提示", "提交文件信息出错", "warning"); console.error("提交文件信息出错"); }); } }])})(angular);
第三部编写后台上传文件和提交表单的代码
