求教如何将后台的json数据传送到前台easyUI中的datagrid中

Answer 1

控制器和jsp：

@RequestMapping(produces="text/plain;charset=UTF-8",value="datagridToJson")
	@ResponseBody
	public String datagridToJson(HttpServletRequest req) throws JsonGenerationException, JsonMappingException, IOException{
		ObjectMapper objectMapper = new ObjectMapper();
		Map map=new HashMap<>();
		Book book=new Book(1, "剪掉你的dingding", "大叔");
		Book book1=new Book(2, "洗掉你的dingding", "大姐");
		List<Book> list=new ArrayList<Book>();
		list.add(book);
		list.add(book1);
		map.put("rows",list);
		map.put("total",2);
		return objectMapper.writeValueAsString(map);
	}
	
	
	 <table class="easyui-datagrid" id="tab1" title="Basic DataGrid" style="width:700px;height:250px"
            data-options="singleSelect:true,collapsible:true,url:'${pageContext.request.contextPath}/easyui/datagridToJson',method:'get'">
        <thead>
            <tr>
                <th data-options="field:'id',width:100">BOOk的ID</th>
                <th data-options="field:'author',width:80,align:'right'">BOOk作者</th>
                <th data-options="field:'name',width:80,align:'right'">BOOk名字</th>
