springMVC如何将controller中Model数据传递到jsp页面

@Controller // 加入到IOC容器
//@RequestMapping(value="/topic")
public class TopicAction {

  @Resource(name = "topicServiceImpl")
  private TopicService topicService;

  /**
   * 首页显示
   */
  @RequestMapping(value="/index")
  public String index(Model model){
    List<Topic> topicList = topicService.getAllTopicList();
    model.addAttribute("topics", topicList);
    System.out.println("封装的model="+model);
    return "index.jsp";
  }
}

[Topic [id=0, time=2016-12-05 08:29:02.0, title=html百度百科, contents=null, isTuiJian=0, good=15, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-05 08:29:04.0, title=JSP简介, contents=null, isTuiJian=0, good=2, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-05 08:28:59.0, title=test, contents=null, isTuiJian=0, good=3, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-05 08:28:52.0, title=test2, contents=null, isTuiJian=0, good=0, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-13 09:29:30.0, title=经典歌曲, contents=null, isTuiJian=0, good=3, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-05 08:28:56.0, title=test4, contents=null, isTuiJian=0, good=0, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-05 09:02:19.0, title=tst2, contents=null, isTuiJian=0, good=30, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-08 14:45:47.0, title=我的世界, contents=null, isTuiJian=0, good=3, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-08 19:39:15.0, title=你的世界, contents=null, isTuiJian=0, good=0, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-09 14:17:17.0, title=test, contents=null, isTuiJian=0, good=0, user=null, replyList=[], type=null], Topic [id=0, time=2016-12-09 14:19:21.0, title=我の, contents=null, isTuiJian=0, good=0, user=null, replyList=[], type=null]]
