springboot中怎么實現文件上傳,針對這個問題,這篇文章詳細介紹了相對應的分析和解答,希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。
第一步編寫上傳的前段頁面
<p> <button type="button" class="btn btn-primary" ng-click="openAddModal()" data-toggle="modal" data-target="#documentOprModal" > 單個文件上傳 </button></p> <!-- 點擊單個文件上傳彈出的模態框 --><p class="modal fade" id="documentOprModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"data-backdrop="static" data-keyboard="false"> <p class="modal-dialog modal-lg" role="document" > <p class="modal-content"> <p class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h5 class="modal-title" id="myModalLabel"> 文檔入庫</h5> </p> <p class="modal-body"> <!--開發--> <form name="docForm" id="docForm"> <p class="form-group"> <label for="jhText">井號:</label> <input type="text" class="form-control" id="jhText" ng-model="document.jh"> </p> <!-- 作者 --> <p class="form-group"> <label for="authorText">作者:</label> <input type="text" class="form-control" id="authorText" ng-model="document.author"> </p> <!-- 單位 --> <p class="form-group"> <label for="unitText">單位:</label> <input type="text" class="form-control" id="unitText" ng-model="document.unit"> </p> <!-- 日期 --> <p class="form-group"> <label for="writeDate">寫作日期:</label> <input type="date" class="form-control" id="writeDate" ng-model="document.writeDate"> </p> <!-- 簡介 --> <p class="form-group"> <label for="introductionTextArea">簡介:</label> <textarea class="form-control" id="introductionTextArea" ng-model="document.introduction" rows="5" cols="60"></textarea> </p> <!-- 可能的查詢關鍵字 --> <p class="form-group"> <label for="keyPackageTextArea">可能的查詢關鍵字:</label> <textarea class="form-control" id="keyPackageTextArea" ng-model="document.keyPackage" rows="5" cols="60"></textarea> </p> <!-- 文件 --> <p class="form-group"> <p id="inputContent"> <input id="importFile" type="file" name="file" class="file-loading"> </p> </p> </form> </p> <p class="modal-footer"> <button type="button" class="btn btn-primary" ng-click="submitFileInfo()"> <i class="fa fa-check"></i>保存 </button> <button type="button" class="btn btn-default" data-dismiss="modal" > <i class="fa fa-ban"></i>取消 </button> </p> </p> </p></p>
第二步寫對應的js頁面
/** * @Name:historyStorageCtrl,井史數據入庫 * @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'); /** *初始化文件上傳 */ function initFileInput(ctrlName, uploadUrl) { var control = $('#' + ctrlName); control.fileinput({ language: 'zh', uploadUrl: uploadUrl, //上傳的地址 allowedFileExtensions: ['doc', 'docx', 'xls', 'xlsx', 'ppt', 'pptx', 'pdf', 'mp4', 'avi','wmv','asf','asx','rm','rmvb','3gp','mov','m4v','dat','mkv','flv','vob'], showUpload: true, //是否顯示上傳按鈕 showCaption: true, //是否顯示標題 showPreview: false, //是否顯示預覽區域 browseClass: "btn btn-primary", //按鈕樣式 previewFileIcon: "<i class='glyphicon glyphicon-king'></i>", }).on('fileuploaderror', fileuploaderror).on("fileuploaded", function (event, data, previewId, index) { // console.log(data);.on('fileselect', fileselect) $scope.$apply(function () { $scope.fileId = data.response.fileId; // 未執行 $scope.document.fileName = data.files[0].name; }); }).on("filecleared", function (event, data, msg) { $scope.$apply(function () { $scope.fileInvalid = false; }); }); return control; } /** * 清空輸入框 */ function importClearFunc() { if ($fileInput) $fileInput.fileinput('clear'); $scope.fileInvalid = false; } /** * 文件上傳錯誤 **/ function fileuploaderror(event, data, msg) { $scope.fileInvalid = true; $scope.$apply(); $('.modal-body .kv-upload-progress').css('display', 'none'); if (!(data.jqXHR.responseJSON)) { //文件類型驗證錯誤 $('#fileError').html(msg); } else { //上傳錯誤 console.log(data); var statusCode = data.jqXHR.responseJSON.message; var errorMsg = HTTP_ERROR_MAP['' + statusCode]; $('#fileError').html(errorMsg); } } /** * add 打開添加模態框 */ $scope.openAddModal = function () { $scope.document = {}; $scope.document.classificationId = 1; $scope.document.starGrade = 5; $timeout(importClearFunc); // openModeldialog(); }; /** * 表單驗證 * @returns {boolean} */ function formVlidate() { if (!$scope.document.introduction) { return false; } if (!$scope.document.keyPackage) { return false; } return true; } /** * 提交表單信息 */ $scope.submitFileInfo = function () { if (!$scope.fileId) { // ToastService.alert("提示", "先上傳文件,再提交表單", "info"); console.error("先上傳文件,再提交表單"); return; } if (!formVlidate()) { // ToastService.alert("提示", "請填充表單", "info"); console.error("請填充表單"); return; } $scope.params = { 'introduction': $scope.document.introduction,//簡介 'keyPackage': $scope.document.keyPackage,//可能查詢的關鍵字 'starGrade': $scope.document.starGrade,//星級 'classificationId': $scope.document.classificationId,//文件的id 'filePath': $scope.fileId,//文件的路徑 '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", "提交文件信息出錯", "warning"); console.error("提交文件信息出錯"); }); } }])})(angular);
第三部編寫后臺上傳文件和提交表單的代碼
