使用ajaxFileUpload上传文件流至服务器，同时提交多个参数
来源：互联网 发布：java输入输出流考题 编辑：程序博客网 时间：2024/05/16 14:50
1.前端界面引入如下两个js文件，注意引入顺序，因为ajaxfileupload会用到jquery，所以jquery应该先引入
<script type="text/javascript" src="/js/jquery.min.js"></script><script type="text/javascript" src="/js/open/ajaxfileupload.js"></script>
<tr> <td>申请单号:</td> <td colspan="7"><input class="common-text required" type="text" name="applyNo" id="applyNo"></input></td><!--提交文件流的时候，同时提交参数--></tr><tr> <td>合同文件：</td> <td><input type="file" id="filePath" name="filePath"></td><!--注意input的类型和name属性--></tr>2.修改ajaxfileupload.js成如下
jQuery.extend({ createUploadIframe: function(id, uri) { //create frame var frameId = 'jUploadFrame' + id; if(window.ActiveXObject) { var io = document.createElement('<iframe id="' + frameId + '" name="' + frameId + '" />'); if(typeof uri== 'boolean'){ io.src = 'javascript:false'; } else if(typeof uri== 'string'){ io.src = uri; } } else { var io = document.createElement('iframe'); io.id = frameId; io.name = frameId; } io.style.position = 'absolute'; io.style.top = '-1000px'; io.style.left = '-1000px'; document.body.appendChild(io); return io }, createUploadForm: function(id, fileElementId, data) { //create form var formId = 'jUploadForm' + id; var fileId = 'jUploadFile' + id; var form = $('<form action="" method="POST" name="' + formId + '" id="' + formId + '" enctype="multipart/form-data"></form>'); var oldElement = $('#' + fileElementId); var newElement = $(oldElement).clone(); $(oldElement).attr('id', fileId); $(oldElement).before(newElement); $(oldElement).appendTo(form); //增加文本参数的支持 if (data) { for (var i in data) { $('<input type="hidden" name="' + i + '" value="' + data[i] + '" />').appendTo(form); } } //set attributes $(form).css('position', 'absolute'); $(form).css('top', '-1200px'); $(form).css('left', '-1200px'); $(form).appendTo('body'); return form; }, ajaxFileUpload: function(s) { // TODO introduce global settings, allowing the client to modify them for all requests, not only timeout s = jQuery.extend({}, jQuery.ajaxSettings, s); var id = new Date().getTime() var form = jQuery.createUploadForm(id, s.fileElementId, s.data); var io = jQuery.createUploadIframe(id, s.secureuri); var frameId = 'jUploadFrame' + id; var formId = 'jUploadForm' + id; // Watch for a new set of requests if ( s.global && ! jQuery.active++ ) { jQuery.event.trigger( "ajaxStart" ); } var requestDone = false; // Create the request object var xml = {} if ( s.global ) jQuery.event.trigger("ajaxSend", [xml, s]); // Wait for a response to come back var uploadCallback = function(isTimeout) { var io = document.getElementById(frameId); try { if(io.contentWindow) { xml.responseText = io.contentWindow.document.body?io.contentWindow.document.body.innerHTML:null; xml.responseXML = io.contentWindow.document.XMLDocument?io.contentWindow.document.XMLDocument:io.contentWindow.document; }else if(io.contentDocument) { xml.responseText = io.contentDocument.document.body?io.contentDocument.document.body.innerHTML:null; xml.responseXML = io.contentDocument.document.XMLDocument?io.contentDocument.document.XMLDocument:io.contentDocument.document; } }catch(e) { jQuery.handleError(s, xml, null, e); } if ( xml || isTimeout == "timeout") { requestDone = true; var status; try { status = isTimeout != "timeout" ? "success" : "error"; // Make sure that the request was successful or notmodified if ( status != "error" ) { // process the data (runs the xml through httpData regardless of callback) var data = jQuery.uploadHttpData( xml, s.dataType ); // If a local callback was specified, fire it and pass it the data if ( s.success ) s.success( data, status ); // Fire the global callback if( s.global ) jQuery.event.trigger( "ajaxSuccess", [xml, s] ); } else jQuery.handleError(s, xml, status); } catch(e) { status = "error"; jQuery.handleError(s, xml, status, e); } // The request was completed if( s.global ) jQuery.event.trigger( "ajaxComplete", [xml, s] ); // Handle the global AJAX counter if ( s.global && ! --jQuery.active ) jQuery.event.trigger( "ajaxStop" ); // Process result if ( s.complete ) s.complete(xml, status); jQuery(io).unbind() setTimeout(function() { try { $(io).remove(); $(form).remove(); } catch(e) { jQuery.handleError(s, xml, null, e); } }, 100) xml = null } } // Timeout checker if ( s.timeout > 0 ) { setTimeout(function(){ // Check to see if the request is still happening if( !requestDone ) uploadCallback( "timeout" ); }, s.timeout); } try { // var io = $('#' + frameId); var form = $('#' + formId); $(form).attr('action', s.url); $(form).attr('method', 'POST'); $(form).attr('target', frameId); if(form.encoding) { form.encoding = 'multipart/form-data'; } else { form.enctype = 'multipart/form-data'; } $(form).submit(); } catch(e) { jQuery.handleError(s, xml, null, e); } if(window.attachEvent){ document.getElementById(frameId).attachEvent('onload', uploadCallback); } else{ document.getElementById(frameId).addEventListener('load', uploadCallback, false); } return {abort: function () {}}; }, uploadHttpData: function( r, type ) { var data = !type; data = type == "xml" || data ? r.responseXML : r.responseText; // If the type is "script", eval it in global context if ( type == "script" ) jQuery.globalEval( data ); // Get the JavaScript object, if JSON is used. if ( type == "json" ) eval( "data = " + data ); // evaluate scripts within html if ( type == "html" ) jQuery("<div>").html(data).evalScripts(); //alert($('param', data).each(function(){alert($(this).attr('value'));})); return data; } }) 3.js中调用ajaxFileUpload举例4.后台接收处理$.ajaxFileUpload({ type : "post", url : "/test/lhpContractUpload",//后台接收url secureuri:false, fileElementId: 'filePath',//file标签的id，name data : { "applyNo":applyNo }, dataType : "json", success : function(data) { $("#lhpContractUpload").show().html(data); }});
public String lhpContractUpload(String applyNo,@RequestParam(value = "filePath") MultipartFile file){ try { InputStream io = file.getInputStream();//获取输入文件流 return openService.lhpContractUpload(applyNo,io); } catch (IOException e){ e.printStackTrace(); } return "上传失败";}
