我尝试使用DataTables做“服务器端分页”.我正在按照本教程完成“http://javahonk.com/spring-mvc-pagination-datatables/”.它使用JSP作为他们的html语言.我在这里使用的是“Thymeleaf”
但是当我试图这样做时,我坚持JSON值已经生成,但它出现在我的控制台中,不会显示在我的HTML页面中
这是我的控制器：
SpringMVCController.java
@RequestMapping(value = "/barangs", method = RequestMethod.GET, produces = "application/json")
public String processFindBarang(HttpServletRequest request) {
//Fetch the page number from client
Integer pageNumber = 0;
if (null != request.getParameter("iDisplayStart"))
pageNumber = (Integer.valueOf(request.getParameter("iDisplayStart"))/10)+1;
//Fetch search parameter
String searchParameter = request.getParameter("sSearch");
//Fetch Page display length
Integer pageDisplayLength = Integer.valueOf(request.getParameter("iDisplayLength"));
//Create page list data
Collection<ReturOrder> returList = createPaginationData(pageDisplayLength);
ReturObjectJson returJsonObject = new ReturObjectJson();
//Set Total display record
returJsonObject.setiTotalDisplayRecords(200);
//Set Total record
returJsonObject.setiTotalRecords(200);
returJsonObject.setAaData(returList);
Gson gson = new GsonBuilder().setPrettyPrinting().create();
String json2 = gson.toJson(returJsonObject);
return json2;
}
它已经很好地返回了JSON,它出现在我的“控制台”区域,同时在我的Eclipse IDE中进行调试
这是我的HTML页面. main.html中
<form method="GET">
<h2>Spring MVC pagination using data tables</h2>
<table width="70%" style="border: 3px;background: rgb(243, 244, 248);"><tr><td>
<table id="tablepage" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>Nomor_Transaksi</th>
<th>Tgl_Trans</th>
<th>FlagCetak</th>
<th>Kd_Plg</th>
</tr>
</thead>
</table>
</td></tr></table>
</form>
这是我在区域的JavaScript
<script type="text/javascript" th:inline="javascript">
//Plug-in to fetch page data
jQuery.fn.dataTableExt.oApi.fnPagingInfo = function ( oSettings )
{
return {
"iStart": oSettings._iDisplayStart,
"iEnd": oSettings.fnDisplayEnd(),
"iLength": oSettings._iDisplayLength,
"iTotal": oSettings.fnRecordsTotal(),
"iFilteredTotal": oSettings.fnRecordsDisplay(),
"iPage": oSettings._iDisplayLength === -1 ?
0 : Math.ceil( oSettings._iDisplayStart / oSettings._iDisplayLength ),
"iTotalPages": oSettings._iDisplayLength === -1 ?
0 : Math.ceil( oSettings.fnRecordsDisplay() / oSettings._iDisplayLength )
};
};
$(document).ready(function() {
$("#tablepage").dataTable( {
"bProcessing": true,
"bServerSide": true,
"sort": "position",
//bStateSave variable you can use to save state on client cookies: set value "true"
"bStateSave": false,
//Default: Page display length
"iDisplayLength": 10,
//We will use below variable to track page number on server side(For more information visit: http://legacy.datatables.net/usage/options#iDisplayStart)
"iDisplayStart": 0,
"fnDrawCallback": function () {
//Get page numer on client. Please note: number start from 0 So
//for the first page you will see 0 second page 1 third page 2...
//Un-comment below alert to see page number
//alert("Current page number: "+this.fnPagingInfo().iPage);
},
"sAjaxSource": "barangs",
"aoColumns": [
{ "mData": "Nomor_Transaksi" },
{ "mData": "Tgl_Trans" },
{ "mData": "FlagCetak" },
{ "mData": "Kd_Plg" },
]
} );
} );
</script>
该值不会显示,它会在我的Web浏览器中执行时给出这些错误.它显示一个警告框,上面写着：“DataTables警告：表id = tablepage – Ajax错误.有关此错误的更多信息,请参阅http://datatables.net/tn/7”
但是当我查看我的eclipse控制台时,JSON值如下：
{
"Nomor_Transaksi": "xxxxx",
"Tgl_Trans": "Jan 15, 2014 12:00:00 AM",
"FlagCetak": "Y",
"Kd_Plg": "MGS "
},
{
"Nomor_Transaksi": "xxxxx",
"Tgl_Trans": "Jan 6, 2014 12:00:00 AM",
"FlagCetak": "Y",
"Kd_Plg": "MGS "
}
]
}", template might not exist or might not be accessible by any of the configured Template Resolvers
我错过了吗？
解决方法:
找到了！我错过了@ResponseBody标签！
所以这是我的控制器功能
@RequestMapping(value = "/barangs", method = RequestMethod.GET, produces = "application/json")
public @ResponseBody String processFindBarang(HttpServletRequest request) {
//Fetch Page display length
Integer pageDisplayLength = Integer.valueOf(request.getParameter("iDisplayLength"));
//Fetch the page number from client
Integer pageNumber = 0;
if (null != request.getParameter("iDisplayStart"))
pageNumber = (Integer.valueOf(request.getParameter("iDisplayStart"))/pageDisplayLength)+1;
/* //Fetch search parameter
String searchParameter = request.getParameter("sSearch");*/
//Create page list data
List<ReturOrder> returList = createPaginationData(pageDisplayLength, pageNumber);
ReturObjectJson returJsonObject = new ReturObjectJson();
//Set Total display record
returJsonObject.setiTotalDisplayRecords(200);
//Set Total record
returJsonObject.setiTotalRecords(200);
returJsonObject.setAaData(returList);
Gson gson = new GsonBuilder().setPrettyPrinting().create();
String json2 = gson.toJson(returJsonObject);
return json2;
}
