springmvc实现导出数据信息为excle表格的示例代码

时间：2022-06-25 08:49:14 编辑：袖梨来源：一聚教程网

1.项目增加导出日志信息

2.项目中导入poi-*.jar等操作excel文件的jar文件

poi-3.7-20120326.jar
poi-excelant-3.7-20101029.jar
poi-ooxml-3.7.jar
poi-ooxml-schemas-3.7.jar

Excel导出就是根据前台条件将参数传到controller，根据参数去数据库中进行查询，查询出list集合，将list集合生成excle数据下载。

代码片段：

Contorller.Java

代码如下

复制代码

/**

* 导出信息

* @param model

@RequestMapping("exportCustomer.do")

@SystemControllerLog(description ="数据库表单导出Excle")

publicvoidexportCustomer(ModelMap model) {

//TODO 如需添加条件

//model.addAttribute("username", nameStr);

//获取需要导出的数据List

List cusList=customerService.exportCustomer(model);

//使用方法生成excle模板样式

HSSFWorkbook workbook = customerService.createExcel(cusList, request);

SimpleDateFormat format =newSimpleDateFormat("yyyyMMddHHmmss");// 定义文件名格式

try{

//定义excle名称 ISO-8859-1防止名称乱码

String msg =newString(

("客户信息_"+ format.format(newDate()) +".xls").getBytes(),

"ISO-8859-1");

// 以导出时间作为文件名

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

response.addHeader("Content-Disposition","attachment;filename="

+ msg);

workbook.write(response.getOutputStream());

}catch(IOException e) {

logger.error(e);

}

2.Service中createExcel方法

代码如下

复制代码

publicHSSFWorkbook createExcel(List cusList,

HttpServletRequest request) {

// 创建一个webbook，对应一个excel文件

HSSFWorkbook workbook =newHSSFWorkbook();

// 在webbook中添加一个sheet,对应excel文件中的sheet

HSSFSheet sheet = workbook.createSheet("客户信息表");

// 设置列宽

sheet.setColumnWidth(0,25*100);

sheet.setColumnWidth(1,35*100);

sheet.setColumnWidth(2,35*100);

sheet.setColumnWidth(3,40*100);

sheet.setColumnWidth(4,45*100);

sheet.setColumnWidth(5,45*100);

sheet.setColumnWidth(6,50*100);

sheet.setColumnWidth(7,80*100);

sheet.setColumnWidth(8,35*100);

sheet.setColumnWidth(9,40*100);

// 在sheet中添加表头第0行

HSSFRow row = sheet.createRow(0);

// 创建单元格，并设置表头，设置表头居中

HSSFCellStyle style = workbook.createCellStyle();

// 创建一个居中格式

style.setAlignment(HSSFCellStyle.ALIGN_CENTER);

// 带边框

style.setBorderBottom(HSSFCellStyle.BORDER_THIN);

// 生成一个字体

HSSFFont font = workbook.createFont();

// 字体增粗

font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);

// 字体大小

font.setFontHeightInPoints((short)12);

// 把字体应用到当前的样式

style.setFont(font);

// 单独设置整列居中或居左

HSSFCellStyle style1 = workbook.createCellStyle();

style1.setAlignment(HSSFCellStyle.ALIGN_CENTER);

HSSFCellStyle style2 = workbook.createCellStyle();

style2.setAlignment(HSSFCellStyle.ALIGN_LEFT);

HSSFCellStyle style3 = workbook.createCellStyle();

style3.setAlignment(HSSFCellStyle.ALIGN_LEFT);

HSSFFont hssfFont = workbook.createFont();

hssfFont.setColor(HSSFFont.COLOR_RED);

hssfFont.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);

style3.setFont(hssfFont);

HSSFCellStyle style4 = workbook.createCellStyle();

style4.setAlignment(HSSFCellStyle.ALIGN_LEFT);

HSSFFont hssfFont1 = workbook.createFont();

hssfFont1.setColor(HSSFFont.COLOR_NORMAL);

hssfFont1.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);

style4.setFont(hssfFont1);

HSSFCell cell = row.createCell(0);

cell.setCellValue("序号");

cell.setCellStyle(style);

cell = row.createCell(1);

cell.setCellValue("客户姓名");

cell.setCellStyle(style);

cell = row.createCell(2);

cell.setCellValue("性别");

cell.setCellStyle(style);

cell = row.createCell(3);

cell.setCellValue("状态");

cell.setCellStyle(style);

cell = row.createCell(4);

cell.setCellValue("电话");

cell.setCellStyle(style);

cell = row.createCell(5);

cell.setCellValue("邮箱");

cell.setCellStyle(style);

cell = row.createCell(6);

cell.setCellValue("地址");

cell.setCellStyle(style);

for(inti =0; i < cusList.size(); i++) {

String logTypeDis ="";

row = sheet.createRow(i +1);

CMcustomer cMcustomer = cusList.get(i);

// 创建单元格，并设置值

// 编号列居左

HSSFCell c1 = row.createCell(0);

c1.setCellStyle(style2);

c1.setCellValue(i);

HSSFCell c2 = row.createCell(1);

c2.setCellStyle(style1);

c2.setCellValue(cMcustomer.getCustomername());//客户姓名

String sexStr = cMcustomer.getSex();//性别 0:女,1:男

String sex="";

if("1".equals(sexStr)) {

sex="男";

}

if("0".equals(sexStr)) {

sex="女";

}

HSSFCell c3 = row.createCell(2);//性别

c3.setCellStyle(style1);

c3.setCellValue(sex);

String statusStr = cMcustomer.getStatus();//客户状态1.在职，2.离职

String status="";

if("1".equals(statusStr)) {

status="在职";

}

if("2".equals(statusStr)) {

status="离职";

}

HSSFCell c4 = row.createCell(3);//状态

c4.setCellStyle(style1);

c4.setCellValue(status);

String customerid = cMcustomer.getCustomerid();//客户id

List phoneList = cMphoneMapper.selectByCustomerid(customerid);

String phone="";

if(phoneList!=null&&phoneList.size()>0) {

for(intj =0; j < phoneList.size(); j++) {

phone = phoneList.get(j).getPhone();

}

HSSFCell c5 = row.createCell(4);//电话

c5.setCellStyle(style1);

c5.setCellValue(phone);

List emailList = cMemailMapper.selectAll(customerid);

String email="";

if(emailList!=null&&emailList.size()>0) {

for(intj =0; j < emailList.size(); j++) {

email = emailList.get(j).getEmail();

}

HSSFCell c6 = row.createCell(5);//邮箱

c6.setCellStyle(style1);

c6.setCellValue(email);

CMaddress cMaddress=newCMaddress();

cMaddress.setCustomerid(customerid);

List adderssList = cMaddressMapper.selectAll(cMaddress);

String adderss="";

if(adderssList!=null&&adderssList.size()>0) {

for(intj =0; j < adderssList.size(); j++) {

adderss = adderssList.get(j).getAddress();

}

HSSFCell c7 = row.createCell(6);//地址

c7.setCellStyle(style1);

c7.setCellValue(adderss);

//使用默认格式

row.createCell(1).setCellValue(cMcustomer.getCustomername());

row.createCell(2).setCellValue(sex);

row.createCell(3).setCellValue(status);

row.createCell(4).setCellValue(phone);

row.createCell(5).setCellValue(email);

row.createCell(6).setCellValue(adderss);

}

returnworkbook;

}

3.页面jsp调用

代码如下	复制代码
//导出信息 functionexporBtn(){ $.ajax({ type:"POST", url:"<%=path%>/customer/exportCustomer.do", success:function(data){ window.open('<%=path%>/customer/exportCustomer.do'); } }); }
