ModelAndView

如：前台：

//查看公告
    		function look() {
    			var row = $('#dg').datagrid('getSelected');
    			if(row) {
    				var id = row.id;
    				window.location.href = "xxLook?id=" + id;
    			}
    
    		}

如果出现乱码问题需要加编码：

window.location.href = "look?dwlx=" +encodeURI(encodeURI(dwlx))+"&ssnd="+ssnd+"&sspc="+sspc;

或者后台接收时：

title= new String( title.getBytes("iso-8859-1"), "UTF-8");

后台：

// 查看
    	@GetMapping("/xxLook")
    	public ModelAndView look(String id) {
    		ModelAndView mv = new ModelAndView();
    		mv.setViewName("azcbdxxlook");
    		AzcBdxx azcBdxx = service.getById(id);
    		mv.addObject("azc", azcBdxx);
    		return mv;
    	}

返回的视图azcbdxxlook.jsp:

如果后台返回的为集合，前台可以用jstl遍历，如：

@GetMapping("/xxLook")
    		public ModelAndView noticeLook(String id){
    			ModelAndView andView=new ModelAndView();
    			andView.setViewName("msgfxblook");
    		
    			MsgFxb msgFxb=service.getMsgFxbById(id);
    			andView.addObject("title",msgFxb.getXxbt() );
    			
    			List<Appendix> list=service.getAppdixList(id);
    			List<String> imglist=new ArrayList<>();
    			List<String> imgid=new ArrayList<>();
    			
    			
    			for(Appendix a:list){
    				
    				imglist.add("../assets/img/"+a.getFjmc());
    				imgid.add(a.getId());
    			}
    			andView.addObject("img", imglist);
    			andView.addObject("imgid", imgid);
    			
    			return andView;
    		}

再如：

//返回商品展示视图
    	@GetMapping("/goodslook")
    	public ModelAndView goGoods(HttpServletRequest req) throws UnsupportedEncodingException{
    		req.setCharacterEncoding("utf-8");
    		ModelAndView mv=new ModelAndView();
    		String title=req.getParameter("title");
    		   title= new String( title.getBytes("iso-8859-1"), "UTF-8");
    		System.out.println("分类"+title);
    		classfiy.setTitle(title);
    		mv.setViewName("goodslook");
    		List<Goodsinfo> list=service.getGoods(classfiy);
    	//	System.out.println(list);
    		mv.addObject("gl", list);
    		return mv;
    	}
