初试poi HssfWorkBook导出excel

昨天看了一个例子，是用户在填写注册信息的时候，能够导出该用户的注册信息，现在仅仅实现了这个功能，这是直接在servlet里面写的！

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setContentType("application/ vnd.ms-excel");//设置正文的MIME类型为excel
String name = request.getParameter("name");
String psswd = request.getParameter("passwd");
String sex = request.getParameter("sex");
String email = request.getParameter("email");
String fileName = "userinfo.xls";
response.setHeader("Content-disposition","attachment;filename="+fileName);
ServletOutputStream out = response.getOutputStream();//响应输出流对象
HSSFWorkbook wb = new HSSFWorkbook();//创建excel表格
HSSFSheet sheet = wb.createSheet("用户注册信息");//创建工作簿
sheet.setColumnWidth(4, 5000);//设置列宽
HSSFRow titleRow = sheet.createRow(0);//设置标题行
HSSFCell titleCell = titleRow.createCell(0);//第一个单元格
titleCell.setCellValue("用户姓名");//第一个值
HSSFCell titleCel2 = titleRow.createCell(1);
titleCel2.setCellValue("用户密码");
HSSFCell titleCel3 = titleRow.createCell(2);
titleCel3.setCellValue("用户性别");
HSSFCell titleCel4 = titleRow.createCell(3);
titleCel4.setCellValue("用户邮箱");
HSSFRow rowValue = sheet.createRow(1);//设置第二行
HSSFCell nameCell = rowValue.createCell(0);
nameCell.setCellValue(name);
HSSFCell passCell = rowValue.createCell(1);
passCell.setCellValue(psswd);
HSSFCell sexCell = rowValue.createCell(2);
sexCell.setCellValue(sex);
HSSFCell emailCell = rowValue.createCell(3);
emailCell.setCellValue(email);
wb.createCellStyle();
wb.write(out);
out.flush();
out.close();
}
