小编给大家分享一下springboot如何实现文件上传步骤解析，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
第一步编写上传的前段页面
<div> <button type="button" class="btn btn-primary" ng-click="openAddModal()" data-toggle="modal" data-target="#documentOprModal" > 单个文件上传 </button> </div> <!-- 点击单个文件上传弹出的模态框 --> <div class="modal fade" id="documentOprModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" data-backdrop="static" data-keyboard="false"> <div class="modal-dialog modal-lg" role="document" > <div class="modal-content"> <div 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"> 文档入库</h5> </div> <div class="modal-body"> <!--开发--> <form name="docForm" id="docForm"> <div class="form-group"> <label for="jhText">井号：</label> <input type="text" class="form-control" id="jhText" ng-model="document.jh"> </div> <!-- 作者 --> <div class="form-group"> <label for="authorText">作者：</label> <input type="text" class="form-control" id="authorText" ng-model="document.author"> </div> <!-- 单位 --> <div class="form-group"> <label for="unitText">单位：</label> <input type="text" class="form-control" id="unitText" ng-model="document.unit"> </div> <!-- 日期 --> <div class="form-group"> <label for="writeDate">写作日期：</label> <input type="date" class="form-control" id="writeDate" ng-model="document.writeDate"> </div> <!-- 简介 --> <div class="form-group"> <label for="introductionTextArea">简介：</label> <textarea class="form-control" id="introductionTextArea" ng-model="document.introduction" rows="5" cols="60"></textarea> </div> <!-- 可能的查询关键字 --> <div class="form-group"> <label for="keyPackageTextArea">可能的查询关键字:</label> <textarea class="form-control" id="keyPackageTextArea" ng-model="document.keyPackage" rows="5" cols="60"></textarea> </div> <!-- 文件 --> <div class="form-group"> <div id="inputContent"> <input id="importFile" type="file" name="file" class="file-loading"> </div> </div> </form> </div> <div 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> </div> </div> </div> </div>
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: "<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
