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

hssfCell.setCellType(HSSFCell.CELL_TYPE_STRING);//该单元格的类型为String

setText(hssfCell,"客户名称");//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");

response.setContentType("application/vnd.ms-excel");

response.setHeader("Content-disposition", "p_w_upload;filename=" + 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);

//如果我们也要传数据过去也是可以的，只需要将查询出来的LIST放在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: '',

fileName: '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 {

List<MultipartFile> files = request.getFiles("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)){

}else {

crmCustBas.setProvinceId("0");

}

}else if("cityId".equals(key)){

BsmArea bsmAreaCityId = basDao.queryOne(BsmArea.class,"name",map.get(key));

if(bsmAreaCityId!=null){

crmCustBas.setCityId(bsmAreaCityId.getId());

}else {

crmCustBas.setCityId("0");

}

}else if("townId".equals(key)){

BsmArea bsmAreaTownId = basDao.queryOne(BsmArea.class,"name",map.get(key));

if(bsmAreaTownId!=null){

}else {

crmCustBas.setTownId("0");

}

}else if("countEmployer".equals(key)){

String count = map.get(key);

Integer countEmployer = Integer.parseInt(count);

crmCustBas.setCountEmployer(countEmployer);

}else if("community".equals(key)){

crmCustBas.setCommunity(map.get(key));

}else if("username".equals(key)){

crmCustBas.setUsername(map.get(key));

}else if("sex".equals(key)){

if("男".equals(map.get(key))){

crmCustBas.setSex("0");

}else {

crmCustBas.setSex("1");

}

}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));

}else if("politics".equals(key)){

crmCustBas.setPolitics(map.get(key));

}else if("mobilePhone".equals(key)){

crmCustBas.setMobilePhone(map.get(key));

}else if("phone".equals(key)){

crmCustBas.setPhone(map.get(key));

}else if("joinOrgnise".equals(key)){

crmCustBas.setJoinOrgnise(map.get(key));

}else if("workExperience".equals(key)){

crmCustBas.setWorkExperience(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

book = Workbook.getWorkbook(inputStream);

Sheet sheet = book.getSheet(sheetCount);

//列数

int columnCount=sheet.getColumns();

//行数

int rowCount=sheet.getRows();

Cell cell = null;

String[] arraycol=arrayCloumns.split(",");

for (int i = startRows; i <rowCount; i++) {

Object obj=UtilBean.getNewClass(object.getClass());

for (int j = 0; j <columnCount; j++) {

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);

}

}

list.add(obj);

}

}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();

}

}

return list;

}

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">

<td><div class="importUserLayer">

<table>

<tbody><tr>

<td width="154" height="57" align="right" valign="top">选择需要导入的文件：</td>
