我使用jQuery DataTables显示MySQL数据库中的分页数据

当我在这个表中显示普通字符时，它在表中显示正确的数据。但是，当我保存Unicode字符时，它只显示？人物

以下是我在此页面的html代码：

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>

//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() {

$("#example").dataTable( {
    "bProcessing": true,
    "bServerSide": true,
    "sort": "position",
    "bStateSave": false,

此表的后端Java代码为：

@RequestMapping(value = "/springPaginationDataTables.web", method = RequestMethod.GET, produces = "application/json")
public @ResponseBody String springPaginationDataTables(HttpServletRequest  request) throws IOException {

    Integer pageNumber = 0;
    if (null != request.getParameter("iDisplayStart"))
        pageNumber = (Integer.valueOf(request.getParameter("iDisplayStart"))/10)+1;     

    Integer pageDisplayLength = Integer.valueOf(request.getParameter("iDisplayLength"));

    List<Township> listTownship = townshipDao.getList(pageNumber, pageDisplayLength);
    int count = townshipDao.getCount();

    JsonObject<Township> townshipJsonObject = new JsonObject<Township>();
    //Set Total display record
    townshipJsonObject.setiTotalDisplayRecords(count);
    //Set Total record
    townshipJsonObject.setiTotalRecords(count);
    townshipJsonObject.setAaData(listTownship);

    Gson gson = new GsonBuilder().setPrettyPrinting().create();
    String json2 = gson.toJson(townshipJsonObject);

    return json2;
}

我在数据表中得到以下输出，显示哪一个？而不是Unicode字符：

请帮助我解决此问题。

尝试在products属性中强制使用字符集，如下所示：

@RequestMappingvalue=/springPaginationDataTables.web，method=RequestMethod.GET，products=application/json；charset=UTF-8

您是否使用UTF-8字符编码编译了java源代码？是的。我已经知道了。你从哪里得到数据？数据库csv？xml？excel？@JuaRoAI，我从数据库中获取数据，转换成JSON格式并绑定表。检查：
