春天mvc 3和谷歌datatable

Question

我是新来的google.visualization.datasource，我想知道是否有一个简单的例子，用一个助手类创建数据表并返回给客户端，但没有使用查询和DataSourceServlet ??因为我已经通过spring mvc控制器实现了我的http请求。

我想实现下面的例子：https://developers.google.com/chart/interactive/docs/dev/dsl_get_started

这里是我的代码：

@Controller 
public class DBcontroller { 
private SimpleDateFormat formater = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 


@SuppressWarnings({ "rawtypes", "unchecked" }) 
@RequestMapping(value = "/getHistoricalData", method = {RequestMethod.POST,RequestMethod.GET}) 
public @ResponseBody DataTable setLampsRequest(@RequestParam String Lampid 
     , @RequestParam String StartDate, @RequestParam String EndDate) throws ParseException{ 

    //converting time values to long 
    Long start = formater.parse(StartDate).getTime(); 
    Long end = formater.parse(EndDate).getTime(); 

    // Create a data table, 
    DataTable data = new DataTable(); 
    ArrayList cd = new ArrayList(); 
    cd.add(new ColumnDescription("name", ValueType.TEXT, "Animal name")); 
    cd.add(new ColumnDescription("link", ValueType.TEXT, "Link to wikipedia")); 
    cd.add(new ColumnDescription("population", ValueType.NUMBER, "Population size")); 
    cd.add(new ColumnDescription("vegeterian", ValueType.BOOLEAN, "Vegetarian?")); 

    data.addColumns(cd); 

    // Fill the data table. 
    try { 
     data.addRowFromValues("Aye-aye", "http://en.wikipedia.org/wiki/Aye-aye", 100, true); 
     data.addRowFromValues("Sloth", "http://en.wikipedia.org/wiki/Sloth", 300, true); 
     data.addRowFromValues("Leopard", "http://en.wikipedia.org/wiki/Leopard", 50, false); 
     data.addRowFromValues("Tiger", "http://en.wikipedia.org/wiki/Tiger", 80, false); 
    } catch (TypeMismatchException e) { 
     System.out.println("Invalid type!"); 
    } 


    return data; 
} 

}
