我正在尝试将数据从 Mysql db 获取到 .jsp 页面：

  <%

  List list = connection.getBookList();
  int id = 0;
  String box = null;

  Iterator<String> it = list.iterator();

  while (it.hasNext()) {
      id = Integer.parseInt(it.next());
      out.print("<tr>");
      for (int i = 0; i < 4; i++) {
          out.print("<td>");
          out.print(it.next());
          out.print("</td>");
  }
  out.print("<td>");
  box = "<input name=r" + id + " type='checkbox'>";
  out.print(box);
  out.print("</td>");
  out.print("</tr>");
 }
%>

这是我的数据库检索类中的方法：

public List getBookList() throws SQLException
   {
      List  BookList = new ArrayList();


      ResultSet results = statement.executeQuery("SELECT * FROM book" );



      while ( results.next() ) {
         BookBean  view  = new BookBean();

        view.setID(results.getString( 1 ));
        view.setName(results.getString( 2 ));
        view.setDescription(results.getString( 3));
        view.setCatID(results.getString( 4));
        view.setUID(results.getString(5 ));
        view.setDateAdded(results.getString( 6 ));
        view.setPicThumb(results.getString( 7 ));
        view.setPicLarge(results.getString( 8 ));




         BookList.add(view);
      }

      return BookList;
   }

如果以上面方法的编写方式在jsp页面中打印我的数据有什么帮助吗？我认为（视图）有所不同，不是吗？

Your iteration should be with BookBean and not with String

<%

  List list = connection.getBookList();
  int id = 0;
  String box = null;

  Iterator<BookBean> it = list.iterator();

  while (it.hasNext()) {

      BookBean view = it.next();
      out.print("<tr>");
      for (int i = 0; i < 4; i++) {
          out.print("<td>");

          //if you have a getter method in bean
          out.print(view.getId());

          out.print("</td>");
  }
  out.print("<td>");
  box = "<input name=r" + view.getId() + " type='checkbox'>";
  out.print(box);
  //out.print(view.getName());
  out.print("</td>");
  out.print("</tr>");
 }
%>
