jquery datatable后台封装数据示例代码后台封装数据示例代码
主要介绍了jquery datatable后台封装数据的示例代码,需要的朋友可以参考下
1.数据转换类数据转换类
public class DataTableReturnObject {
private int iTotalRecords;
private int iTotalDisplayRecords;
private String sEcho;
private String[][] aaData;
public DataTableReturnObject(int totalRecords, int totalDisplayRecords, String echo, String[][] d) {
this.setiTotalRecords(totalRecords);
this.setiTotalDisplayRecords(totalDisplayRecords);
this.setsEcho(echo);
this.setAaData(d);
}
public void setiTotalRecords(int iTotalRecords) {
this.iTotalRecords = iTotalRecords;
}
public int getiTotalRecords() {
return iTotalRecords;
}
public void setiTotalDisplayRecords(int iTotalDisplayRecords) {
this.iTotalDisplayRecords = iTotalDisplayRecords;
}
public int getiTotalDisplayRecords() {
return iTotalDisplayRecords;
}
public void setsEcho(String sEcho) {
this.sEcho = sEcho;
}
public String getsEcho() {
return sEcho;
}
public void setAaData(String[][] aaData) {
this.aaData = aaData;
}
public String[][] getAaData() {
return aaData;
}
}
2帮助类帮助类
public class BaseController {
protected JSONResponse successed(Object obj) {
JSONResponse ret = new JSONResponse();
ret.setSuccessed(true);
ret.setReturnObject(obj);
return ret;
}
}
3.实现类实现类
public JSONResponse searchList(HttpServletRequest request , HttpServletResponse response ,String sEcho) throws Exception {
//convertToMap定义于父类，将参数数组中的所有元素加入一个HashMap
Map<Object, Object> objQueryMap = new HashMap<Object, Object>();
String jsondata = request.getParameter("aoData");
JSONArray jsonarray = JSONArray.fromObject(jsondata);
String strDisplayStart ="";
String strDisplayLength="";
String[] arrayColumen = new String[new JSONUser().toArray().length];
int strSortId = 0;
String strSort = "";
for(int i=0;i<jsonarray.size();i++) //从传递参数里面选出待用的参数
{
JSONObject obj=(JSONObject)jsonarray.get(i);
String strName = (String)obj.get("name");
