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:

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>安置处查看</title>
<script src="../assets/js/scripts/jquery.min.js" type="text/javascript"></script>
<script>
	function fh() {
		window.location.href = "azcbdxx";
	}
</script>
</head>
<body>
	<table id="declaretable" class="declaretable" border="1"
		cellpadding="0" cellspacing="0">
		
		<tr>
			<td colspan="7" align="center">士兵基本信息</td>
		</tr>
		<tr>
			<td>身份证号码</td>
			<td>${azc.sfzhm }</td>
			<td>姓名</td>
			<td>${azc.xm }</td>
			<td>籍贯</td>
			<td colspan="2">${azc.jg }</td>
		</tr>
	<tr>

				<td colspan="6"><input type="button" value="返回" onclick="fh()"></td>
		</tr></table>
</body>
</html>

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;
		}
		
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>法宣办查看</title>
<script src="../assets/js/scripts/jquery.min.js" type="text/javascript"></script> 
<script>
function fh(){
	window.location.href="msgfxb";
}

function download(id){
	
	var dt="&id="+id;
	$.post("download",dt,function(data){
		alert(data.msg);
	});
	
}
</script>
</head>
<body>

<table>
				<tr>
					<td>信息标题</td>
					<td>${title}</td>
				</tr>
				
				<tr>
					<td>附件</td>
				</tr>
				<tr>
					<c:forEach items="${img}" var="li" varStatus="s">  
					
					      <td><img alt="" src=<c:out value="${li}"></c:out>> 
					      
					      
					    
					      </td>
                    </c:forEach> 
                    </tr>
                    <tr>
                    <c:forEach items="${imgid}" var="li" varStatus="s">  
					
					   
					      
					     <td> <button  onclick="download('${li}')">下载</button>
					    
					      </td>
                    </c:forEach> 
				</tr>
				
				<td><input type="button" value="返回" onclick="fh()"></td>
			</table>
</body>
</html>

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;
	}
goodslook.jsp: 

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
	<c:forEach items="${gl}" var="li" varStatus="s">
		<c:out value="${li.title }"></c:out>
	</c:forEach>
</body>
</html>
