实例中的静态数组，怎么转化从数据库中取数，谢谢

@Bind(id="myDataGrid",attribute="mergedColumns")
private String[] mergedColumns = new String[] {"test1"};
这是个初始化状态
@DataModel
private GridArray[] myDataGrid = new GridArray[] {
    new GridArray("1", "1", "1"), 
    new GridArray("2", "1", "2"),
    new GridArray("2", "3", "3"), 
    new GridArray("2", "5", "4"),
    new GridArray("2", "5", "5")
};

@DataModel
private GridArray[] myDataGrid = new GridArray[] {
    从数据库中取数，是用for循环吗？
};

1、jdbc取ResultSet
2、循环创建GridArray 添加到List
3、List.toArray() 转换为数组
