实现图片的轮播效果

1.显示页面：index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="UTF-8"%><%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
        
    
        
                 
              
         
    
    
    
        
     
                  <%-- 
      ${step } --%>               
              
         
    

2.后台返回逻辑:

@Controllerpublic class PicController {    @Resource    private PicService picServiceImpl;    @RequestMapping("/")    public String welcome(Model model){        model.addAttribute("list",picServiceImpl.show());        return "/index.jsp";    }}
