后台页面:
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { //System.out.println(this.getServletContext().getRealPath (\"/\")); try{ Workbook wb = Workbook.getWorkbook( new File(this.getServletContext().getRealPath (\"/\")+\"data.xls\")); System.out.println(\"2222222\"); List<Data> data = new ArrayList<Data>(); for(int i=1;i<wb.getSheet(0).getRows();i++){ Cell[] cell = wb.getSheet(0).getRow(i); data.add(new Data(cell[0].getContents(),cell[1].getContents(),cell[2].getContents())); System.out.println(cell[1].getContents()); } wb.close(); request.setAttribute(\"data\", data); request.getRequestDispatcher(\"../index.jsp\").forward(request, response); }catch(Exception e){ e.printStackTrace(); } }
Data.java
public class Data { private String id; private String name; private String password; public Data() { super(); // TODO Auto-generated constructor stub } public Data(String id, String name, String password) { super(); this.id = id; this.name = name; this.password = password; } public String getId() { return id; }
前台页面:
Index.jsp:
<body> <form action=\"servlet/getExcelData\" method=\"post\"> <input type=\"submit\" id=\"tijiao\" value=\"submit\"> </form> <% List<Data> data = new ArrayList<Data>(); data=(List<Data>)request.getAttribute(\"data\"); if(data!=null&&data.size()>0) for(Data d:data){ out.println(d.getId()+\"---\"+d.getName()+\"---\"+d.getPassword()); } %> </body>
