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
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
/**
* 导出信息
* @param model
*/
@RequestMapping("exportCustomer.do")
@SystemControllerLog(description = "数据库表单导出Excle")
public void exportCustomer(ModelMap model) {
//TODO 如需添加条件
//model.addAttribute("username", nameStr);
//获取需要导出的数据List
List<CMcustomer> cusList=customerService.exportCustomer(model);
//使用方法生成excle模板样式
HSSFWorkbook workbook = customerService.createExcel(cusList, request);
SimpleDateFormat format = new SimpleDateFormat("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 = new String(
("客户信息_" + format.format(new Date()) + ".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
public HSSFWorkbook createExcel(List<CMcustomer> cusList,
HttpServletRequest request) {
// 创建一个webbook，对应一个excel文件
HSSFWorkbook workbook = new HSSFWorkbook();
// 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 (int i = 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<CMphone> phoneList = cMphoneMapper.selectByCustomerid(customerid);
String phone="";
if (phoneList!=null&&phoneList.size()>0) {
for (int j = 0; j < phoneList.size(); j++) {
phone = phoneList.get(j).getPhone();
}
}
HSSFCell c5 = row.createCell(4);//电话
c5.setCellStyle(style1);
c5.setCellValue(phone);
List<CMemail> emailList = cMemailMapper.selectAll(customerid);
String email="";
if (emailList!=null&&emailList.size()>0) {
for (int j = 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=new CMaddress();
cMaddress.setCustomerid(customerid);
List<CMaddress> adderssList = cMaddressMapper.selectAll(cMaddress);
String adderss="";
if (adderssList!=null&&adderssList.size()>0) {
for (int j = 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);
}
return workbook;
}
3.页面jsp调用
//导出信息
function exporBtn(){
$.ajax({
type:"POST",
url:"<%=path%>/customer/exportCustomer.do",
success:function(data){
window.open('<%=path%>/customer/exportCustomer.do');
}
});
}
