jquery datatable后台封装数据示例代码_jquery

1.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

public class BaseController { 
protected JSONResponse successed(Object obj) { 
JSONResponse ret = new JSONResponse(); 
ret.setSuccessed(true); 
ret.setReturnObject(obj); 
return ret; 
} 
}

3.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

4.查询方法

public Map

注意存放的数组对象的属性必须与前端页面显示的列保持一样的个数
