java导出Excel表格简单的方法

List<CmsAction> list = actionMng.getList(contentId);
String[] tableHeader = {"姓名", "手机号"};
short cellNumber = (short) tableHeader.length;// 表的列数
HSSFWorkbook workbook = new HSSFWorkbook(); // 创建一个excel
HSSFCell cell = null; // Excel的列
HSSFRow row = null; // Excel的行
HSSFCellStyle style = workbook.createCellStyle(); // 设置表头的类型
style.setAlignment(HSSFCellStyle.ALIGN_CENTER);
HSSFCellStyle style1 = workbook.createCellStyle(); // 设置数据类型
style1.setAlignment(HSSFCellStyle.ALIGN_CENTER);
HSSFFont font = workbook.createFont(); // 设置字体
HSSFSheet sheet = workbook.createSheet("sheet1"); // 创建一个sheet
HSSFHeader header = sheet.getHeader();// 设置sheet的头
try {
if (list.size() < 1) {
header.setCenter("查无资料");
} else {
header.setCenter("报名表");
row = sheet.createRow(0);
row.setHeight((short) 400);
for (int k = 0; k < cellNumber; k++) {
cell = row.createCell(k);// 创建第0行第k列
cell.setCellValue(tableHeader[k]);// 设置第0行第k列的值
sheet.setColumnWidth(k, 8000);// 设置列的宽度
font.setColor(HSSFFont.COLOR_NORMAL); // 设置单元格字体的颜色.
font.setFontHeight((short) 350); // 设置单元字体高度
style1.setFont(font);// 设置字体风格
cell.setCellStyle(style1);
}
for (int i = 0; i < list.size(); i++) {
CmsAction cmsAction = list.get(i);
JSONObject jobject =new JSONObject();
jobject.put("name", cmsAction.getName());
jobject.put("phone", cmsAction.getPhone());
row = sheet.createRow((short) (i + 1));// 创建第i+1行
row.setHeight((short) 400);// 设置行高
if (cmsAction.getName() != null) {
cell = row.createCell(0);// 创建第i+1行第0列
cell.setCellValue(cmsAction.getName());// 设置第i+1行第0列的值
cell.setCellStyle(style);// 设置风格
}
if (cmsAction.getPhone() != null) {
cell = row.createCell(1); // 创建第i+1行第1列
cell.setCellValue(cmsAction.getPhone());// 设置第i+1行第1列的值
cell.setCellStyle(style); // 设置风格
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
OutputStream out = null;// 创建一个输出流对象
try {
out = response.getOutputStream();//
response.setHeader("Content-disposition", "attachment; filename=" + "cmsAction.xls");// filename是下载的xls的名，建议最好用英文
response.setContentType("application/vnd.ms-excel;charset=UTF-8");// 设置类型
response.setHeader("Pragma", "No-cache");// 设置头
response.setHeader("Cache-Control", "no-cache");// 设置头
response.setDateHeader("Expires", 0);// 设置日期头
workbook.write(out);
out.flush();
workbook.write(out);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {

if (out != null) {
out.close();
}

} catch (IOException e) {
e.printStackTrace();
}

}

在HTML中

$('#js-export').click(function(){
    window.location.href="/jeecmsv9/api/front/action/daochu?contentId=120";
});

<button id="js-export" type="button" class="btn btn-primary">导出Excel</button>
