周末闲来无事就先把Java导入导出的整理出来
一、导出excel模板(只是创建excel格式，供别人填写，我刚学的方法还比较笨，希望谅解哈，以后有比较好的再补上)
1.1 代码如下 我的都是应用于springmvc的示例
public class ExcelView extends AbstractExcelView {
String [] list={"男","女"};//生成的excel模板，对于性别就有下拉框可以选择了
@Override
protected void buildExcelDocument(Map<String, Object> model, HSSFWorkbook workbook, HttpServletRequest request, HttpServletResponse response) throws Exception {
//To change body of implemented methods use File | Settings | File Templates.
HSSFSheet hssfSheet = workbook.createSheet("客户基本信息");
hssfSheet.setDefaultColumnWidth(20);// 设置的每一列的默认宽度
HSSFCell hssfCell = getCell(hssfSheet,0,0);//声明第一行第一列
//该单元格的类型为String
//该单元格的文本
hssfCell = getCell(hssfSheet,0,1);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"省(福建省)");
hssfCell = getCell(hssfSheet,0,2);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"市(厦门市)");
hssfCell = getCell(hssfSheet,0,3);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"区/悬");
hssfCell = getCell(hssfSheet,0,4);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"公司名称");
hssfSheet.setColumnWidth(4, 30);
hssfCell = getCell(hssfSheet,0,5);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"公司详细地址");
hssfSheet.setColumnWidth(5, 100);
hssfCell = getCell(hssfSheet,0,6);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell, "职工人数");
hssfCell = getCell(hssfSheet,0,7);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"所属行业");
hssfSheet.setColumnWidth(7,50);
hssfCell = getCell(hssfSheet,0,8);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"所属社区");
hssfCell = getCell(hssfSheet,0,9);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"登记人姓名");
hssfCell = getCell(hssfSheet,0,10);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
CellRangeAddressList regions = new CellRangeAddressList(0,1000,10,10);
DVConstraint constraint = DVConstraint.createExplicitListConstraint(list);//创建下拉选择
HSSFDataValidation data_validation = new HSSFDataValidation(regions,constraint);
hssfSheet.addValidationData(data_validation);
setText(hssfCell, "登记人性别");
hssfCell = getCell(hssfSheet,0,11);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"***号");
hssfCell = getCell(hssfSheet,0,12);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"生日");
hssfCell = getCell(hssfSheet,0,13);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"户籍");
hssfCell = getCell(hssfSheet,0,14);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"学历");
hssfCell = getCell(hssfSheet,0,15);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"毕业院校");
hssfCell = getCell(hssfSheet,0,16);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"政治面貌");
hssfCell = getCell(hssfSheet,0,17);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"手机号码");
hssfCell = getCell(hssfSheet,0,18);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"电话号码");
hssfCell = getCell(hssfSheet,0,19);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"邮箱");
hssfCell = getCell(hssfSheet,0,20);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"邮编");
hssfCell = getCell(hssfSheet,0,21);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"传真");
hssfCell = getCell(hssfSheet,0,22);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"爱好");
hssfCell = getCell(hssfSheet,0,23);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"职位");
hssfCell = getCell(hssfSheet,0,24);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"加入的社团或组织");
hssfCell = getCell(hssfSheet,0,25);
hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);
setText(hssfCell,"工作经历");
application/vnd.ms-excel");
URLEncoder.encode("客户基本信息模板.xls","utf-8"));
OutputStream ouputStream = response.getOutputStream();
workbook.write(ouputStream);
ouputStream.flush();
ouputStream.close();
}
}Controller下的代码：
@RequestMapping(value = "download_template_excel.do")
public ModelAndView downLoadTemplateExcel(ModelMap modelMap){
ExcelView excelView = new ExcelView();
return new ModelAndView(excelView);
modelMap里面，然后通过new ModelAndView(excelView,modelMap)将数据传给excelView，在该类里面进行数据添加就可以了。
}二、导入excel并解析得到数据
目前做的文件上传是直接点击button按钮就可以选择文件上传，通过iframe嵌入上传文件的表单
所引用的JS文件：
(function($) {
var noop = function(){ return true; };
var frameCount = 0;
$.uploadDefault = {
url: '',
filedata',
dataType: 'json',
params: {},
onSend: noop,
onComplate: noop
};
$.upload = function(options) {
var opts = $.extend(jQuery.uploadDefault, options);
if (opts.url == '') {
return;
}
var canSend = opts.onSend();
if (!canSend) {
return;
}
var frameName = 'upload_frame_' + (frameCount++);
var iframe = $('<iframe style="position:absolute;top:-9999px" />').attr('name', frameName);
var form = $('<form method="post" style="display:none;" enctype="multipart/form-data" />').attr('name', 'form_' + frameName);
form.attr("target", frameName).attr('action', opts.url);
// form中增加数据域
var formHtml = '<input type="file" name="' + opts.fileName + '">';
for (key in opts.params) {
formHtml += '<input type="hidden" name="' + key + '" value="' + opts.params[key] + '">';
}
form.append(formHtml);
iframe.appendTo("body");
form.appendTo("body");
// iframe 在提交完成之后
iframe.load(function() {
var contents = $(this).contents().get(0);
var data = $(contents).find('body').html();
var first = data.indexOf("{");
var last = data.lastIndexOf("}");
data = data.substring(first,last+1);
if ('json' == opts.dataType) {
data = window.eval（'(' + data + ')');
}
opts.onComplate(data);
setTimeout(function() {
iframe.remove();
form.remove();
}, 5000);
});
// 文件框
var fileInput = $('input[type=file][name=' + opts.fileName + ']', form);
fileInput.change(function() {
form.submit();
});
fileInput.click();
};
})(jQuery);
页面的JS：
function doImportExcel(){
$.upload({
url:"import_crmCustBas.json",
params:{},
onComplate:function(data){
doSearch();
ChtUtil.getMessage().show("导入成功...");
}
});
}
action:
@RequestMapping(value = "import_crmCustBas.json",method = RequestMethod.POST)
public ModelMap importExcel(ModelMap modelMap,MultipartHttpServletRequest request)throws IOException, BasException {
filedata");
if(files!=null){
for (MultipartFile file : files) {
InputStream in = file.getInputStream();
//解析Excel
crmCustBasServiceImpl.importExcel(in);
}
}
modelMap = SpringModelTools.convertAjaxSuccess(modelMap);
return modelMap;
}
service:
public boolean importExcel(InputStream inputStream)throws IOException, BasException {
boolean flag = true;
List<Map<String,String>> list = UtilExcel.resolveExcel("custName,provinceId,cityId,townId,enterpriseName,enterpriseAddress,countEmployer,industry,community,username,sex,idCardNo,birthday,houseHold,degreeEducation,graduateSchool, politics,mobilePhone,phone,email,zip,chuanZhen,enjoy,position,joinOrgnise,workExperience", inputStream, 0, new HashMap<String,String>(), 1);
if(list.size()>0){
for(Map<String,String> map :list){
CrmCustBas crmCustBas = new CrmCustBas();
for(String key:map.keySet()){
if("custName".equals(key)){
crmCustBas.setCustName(map.get(key));

}
}else if("idCardNo".equals(key)){
crmCustBas.setIdCardNo(map.get(key));
}else if("birthday".equals(key)){
String str = map.get(key);
Date birthday = UtilDate.parseDate(str);
crmCustBas.setBirthday(birthday);
}else if("houseHold".equals(key)){
crmCustBas.setHouseHold(map.get(key));
}else if("degreeEducation".equals(key)){
crmCustBas.setDegreeEducation(map.get(key));
}else if("graduateSchool".equals(key)){
crmCustBas.setGraduateSchool(map.get(key));

}
}
if(!"".equals(crmCustBas.getMobilePhone())&&crmCustBas.getMobilePhone()!=null){
QueryCondition queryCondition = new QueryCondition();
queryCondition.setQueryObject(CrmCustBas.class);
queryCondition.addField(new QueryField("mobilePhone",crmCustBas.getMobilePhone(),QueryField.CONDITION_EQ));
queryCondition.addField(new QueryField("custName",crmCustBas.getCustName(),QueryField.CONDITION_EQ));
List<CrmCustBas> haveList = basDao.query(queryCondition);
if(haveList.size()>0){
continue;
}else{
crmCustBas.setCustNo(getNo());
crmCustBas.setCustPoint(0);
basDao.save(crmCustBas);
}
}
}
}
return flag;
}UtilExcel:
public static List resolveExcel(String arrayCloumns,InputStream inputStream,int sheetCount,Object object,int startRows) throws BasException{
List list=new ArrayList();
Workbook book =null;
try {
//解析模板为,号分割串
String arrcol=arraycol[j];
cell =sheet.getCell(j, i);
String val=cell.getContents();
//如果是日期类型
if(cell.getType() == CellType.DATE){
DateCell datec11 = (DateCell)cell;
Date date = datec11.getDate();
val = UtilDate.formatDate(date);
}
//如果是金额类型
if(val.contains("$")){
val = val.replace("$", "").replace(",", "");
}
if(object instanceof Map){
((Map)obj).put(arrcol,val);
}
else{
BeanUtils.setProperty(obj, arrcol, val);
}
}catch (Exception e) {
log.error("excel解析错误,错误消息："+e.getMessage());
throw new BasRuntimeException("excel解析错误",e);
}finally{
if(book!=null){
book.close();
}
}
}以上一二是我在CRM用的方式，接下来是我在活动平台项目所用的方式，其实也差不多，但是为了让自己可以记住，还是将其写下来了。
三、导入excel
<form id="formUpload" name="formUpload" action="<%=request.getContextPath()%>/import_linkman_excel.do" method="post" enctype="multipart/form-data">

<tbody><tr>
<td width="154" height="57" align="right" valign="top">选择需要导入的文件：</td>
<td width="434"><p>
myfiles" style="border: 1px solid #CCCCCC; height: 24px;background: #FFFFFF" name="myfiles" size="45">
