我在尝试在JSP中输出数组时遇到问题:

@RequestMapping(value="/searchResult.do", method = RequestMethod.POST)
ModelAndView search(HttpServletRequest request, HttpServletResponse response) throws SQLException
{
    String keyword = request.getParameter("keyword");

    String within = request.getParameter("witin");

    String status = request.getParameter("status");

    String query="select id,title,description,story_type,uploaded_date,popularity from story where status='"+status+"' and title like '"+'%'+keyword+'%'+"'";
     stmt= (Statement) DBManager.getMyConnection();
     rs = stmt.executeQuery(query);
     Map map = new HashMap();
     List wordList = new ArrayList();
     if(keyword!=null){
          while (rs.next()) {
          String id = rs.getString("id");
          String title = rs.getString("title");
          String description = rs.getString("description");
          String parent = rs.getString("uploaded_date");
          String type = rs.getString("story_type");
          String pop = rs.getString("popularity");
          wordList.add(id);
          wordList.add(title);
          wordList.add(type);
          wordList.add(description);
          wordList.add(parent);
          wordList.add(pop);
          map.put("wordList", wordList);
           }
          return new ModelAndView("searchResult",map);
     }
      return new ModelAndView("search");
}
在JSP中我使用${wordList}打印

  

[20,印度赢得了世界杯,体育,这个   是我的杯子,2011-03-26,2,27,印度   赢得世界杯,体育,xyz,2011-04-08,   2]

......这些是一个数组中的两个记录。

如何在JSP中的单独行中打印每个项目?

您的名为wordList的变量是一个集合。要显示集合的元素,可以使用forEach。

有一个很好的例子here和更短的例子here
