Ext文件上传

* Ext上传：
ext文件上传需要扩展控件的支持：
<form id="uploadFileForm" action="" method="post" enctype="multipart/form-data">
<div id="fileupload" style="cursor:hand;"></div>
</form>
1 前台js代码
var uploadForm = new Ext.BasicForm('uploadFileForm');

var fileUploadBt = new Ext.ux.form.FileUploadField({
renderTo: 'fileupload',
buttonOnly: true,
buttonText: 'Excel导入',
buttonCfg: {
iconCls: 'download'
//tooltip: '从Excel导入物料信息'
},
listeners: {
'fileselected': function(fb, v){
//v 为文件路径
if(fac.getValue() == ''){
Ext.Msg.alert('操作提示', '请先选择一个成本中心或填写内部订单号！');
fb.reset();
}else{
indexFun.addMarcFromExcel(v);
}
}
}
});
uploadForm.add(fileUploadBt);

addMarcFromExcel :function(filePath){
uploadForm.submit({
fileUpload: true,
standardSubmit: true,
url: '<c:out value="${path}" />/purchaseApply.htm?method=parseExcel',
params: {
costCenter: costCenter.getValue(),
factNo: costCenterCmbStore.getAt(costCenterCmbStore.find('costNo',costCenter.getValue())).get('factNo'),
internalOrder: internalOrder.getValue()
},
waitMsg: '文件上传中，请等待...',
waitTitle: '上传进度条',
success: function(form,action){
yyExt.info('导入成功', msgContent);
for(var i=0;i<action.result.prdArr.length;i++){
indexFun.insertMarcToGrid(action.result.prdArr[i]);
}
form.reset();
},
failure: function(form, action) {
form.reset();
switch (action.failureType) {
case Ext.form.Action.CLIENT_INVALID:
Ext.Msg.alert('导入失败', 'Form fields may not be submitted with invalid values');
break;
case Ext.form.Action.CONNECT_FAILURE:
Ext.Msg.alert('导入失败', 'Ajax communication failed');
break;
case Ext.form.Action.SERVER_INVALID:
Ext.Msg.alert('导入失败', action.result.msg);
}
}
});
}

2 后台java代码：
/**
* org.apache.commons.fileupload.servlet.ServletFileUpload
* 采用apache的ServletFileUpload解析request中的文件，并将文件相关信息封装进一个FileBean对象
*/
FileUploadUtil fileTool = new FileUploadUtil();
fileTool.setServletFileUpload(this.getServletFileUpload());
fileTool.setSizeMax(this.getFileMaxSize());
fileTool.init(request);
fileTool.setSaveFile(false); //上传的文件不保存到硬盘
FileBean fileBean = fileTool.saveFile();
/*
* 提取其他参数
*/
String costCenter = fileTool.getParameter("costCenter"); //成本中心
String factNo = fileTool.getParameter("factNo"); //工厂编号
String internalOrder = fileTool.getParameter("internalOrder"); //内部订单

* Ext下载：Ext没有对下载做任何处理，下载采用一般方式即可。
采用form提交方式：
<form id="queryForm" target="myframe" method="post">
<input type="text" id="marcNo" name="marcNo" style="width: 180px;">
<input type="text" id="marcName" name="marcName" style="width: 100px">
</form>
//导出物料信息
download: function(){
$("queryForm").action = "<c:out value="${path}"/>/marcInfo.htm?method=download";
$("queryForm").submit();
}
后台java代码：
public ModelAndView download(HttpServletRequest request,HttpServletResponse response) throws Exception{
response.setCharacterEncoding(this.DEFAULT_ENCODE);
//取得输出流
OutputStream out = response.getOutputStream();
//清空输出流
response.reset();
try {
/**
* 1 提取条件参数
*/
String marcNo = RequestUtil.getParameter(request, "marcNo", null); //物料编码
String marcName = RequestUtil.getParameter(request, "marcName", null); //品名

//设置响应头和下载保存的文件名
response.setHeader("Content-Type","text/html; charset=UTF-8");
response.setHeader("content-disposition","attachment;filename="+excelModel.getPath());
//定义输出类型
response.setContentType("APPLICATION/msexcel");
/**
* 2 根据条件参数得到相关文件的输出流，将输出流写回前台
*/

} catch (Exception e) {
log.error("下载物料信息出错："+e.getMessage());
}finally{
out.close();
out.flush();
}
return new ModelAndView(this.indexView,"sessionUserName",super.getSessionUser(request).getUserName());
}
