本案例是为下拉列表组装最近三周的数据，效果如下

步骤如下：
1. 新建java类获取并组装近三周数据，代码如下：
package projectTaskMng;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import com.sunsheen.jfids.system.base.composite.data.page.java.IPageDataListSource;
import com.sunsheen.jfids.system.data.component.IDataComponent;
import com.sunsheen.jfids.system.data.component.combo.ComboItem;
public class WeekList implements IPageDataListSource{

@Override
public List<?> getListData(HttpServletRequest arg0, Map<String, Object> arg1) {
// TODO Auto-generated method stub
List<IDataComponent> list = new ArrayList<IDataComponent>();
//获取年份
Calendar cal = Calendar.getInstance();
int year = cal.get(Calendar.YEAR);

//获取当前周次
Calendar calendar = Calendar.getInstance();
calendar.setFirstDayOfWeek(Calendar.MONDAY);
calendar.setTime(new Date());
System.out.println("当前周为"+calendar.get(Calendar.WEEK_OF_YEAR));
int week = calendar.get(Calendar.WEEK_OF_YEAR);

//上一周
int lastWeek = week - 1;
ComboItem c1 = new ComboItem();
c1.setCode(Integer.toString(year) + "-" +Integer.toString(lastWeek));
c1.setText(Integer.toString(year) + "-" +Integer.toString(lastWeek));
list.add(c1);

//本周
ComboItem c2 = new ComboItem();
c2.setCode(Integer.toString(year) + "-" +Integer.toString(week));
c2.setText(Integer.toString(year) + "-" +Integer.toString(week));
list.add(c2);

//下一周
int nextWeek = week + 1;
ComboItem c3 = new ComboItem();
c3.setCode(Integer.toString(year) + "-" +Integer.toString(nextWeek));
c3.setText(Integer.toString(year) + "-" +Integer.toString(nextWeek));
list.add(c3);

return list;
}

}

2. 创建服务装配文件，组装构件
