불친절한자수씨

기존의 소스...
public class GridColumnPropertySource implements IPropertySource { private GridColumn gridColumn; public GridColumnPropertySource(GridColumn gridColumn) { this.gridColumn = gridColumn; } @Override public Object getEditableValue() { return null; } @Override public IPropertyDescriptor[] getPropertyDescriptors() { List<IPropertyDescriptor> properties = new ArrayList<IPropertyDescriptor>(); PropertyDescriptor labelTextDescriptor = new TextPropertyDescriptor(GridColumn.PROPERTY_TITLE, "타이틀"); properties.add(labelTextDescriptor); PropertyDescriptor borderSizeDescriptor = new TextPropertyDescriptor(GridColumn.PROPERTY_WIDTH, "너비"); properties.add(borderSizeDescriptor); return properties.toArray(new IPropertyDescriptor[0]); } @Override public Object getPropertyValue(Object id) { if (id.equals(GridColumn.PROPERTY_WIDTH)) return "" + gridColumn.getWidth(); if (id.equals(GridColumn.PROPERTY_TITLE)) return gridColumn.getTitle(); return null; } @Override public boolean isPropertySet(Object id) { return false; } @Override public void resetPropertyValue(Object id) { } @Override public void setPropertyValue(Object id, Object value) { if (id.equals(GridColumn.PROPERTY_WIDTH)) { try { gridColumn.setWidth(Integer.parseInt((String) value)); } catch (NumberFormatException e) {} } else if (id.equals(GridColumn.PROPERTY_TITLE)) { gridColumn.setTitle((String) value); } } }


자동화 처리된 소스...
public class GridColumn extends BaseModel implements IAdaptable, IBeanConvertable { @PropertyDescription(label = "타이틀", category = "컬럼", field = "title") public static final String PROPERTY_TITLE = "grid column title"; @PropertyDescription(label = "너비", category = "컬럼", field = "width") public static final String PROPERTY_WIDTH = "grid column width"; ... }
public class GridColumnPropertySource implements IPropertySource { private GridColumn gridColumn; private PropertySourceHelpers descriptorHelper; public GridColumnPropertySource(GridColumn gridColumn) { this.gridColumn = gridColumn; descriptorHelper = new PropertySourceHelpers(gridColumn.getClass()); } @Override public Object getEditableValue() { return null; } @Override public IPropertyDescriptor[] getPropertyDescriptors() { return descriptorHelper.getPropertyDescriptors(); } @Override public Object getPropertyValue(Object id) { return descriptorHelper.getPropertyValue(gridColumn, id); } @Override public boolean isPropertySet(Object id) { return false; } @Override public void resetPropertyValue(Object id) { } @Override public void setPropertyValue(Object id, Object value) { descriptorHelper.setPropertyValue(gridColumn, id, value); } }

프로퍼티 상수에 PropertyDescription 어노테이션을 정의하여 PropertySourceHelpers 에 처리를 위임합니다.
알아서 PropertyDescriptor 들을 반환해주고 값을 얻어오고 설정을 하게 됩니다.

기존 방식은 한 두개야 머 저렇게 작업하겠지만 몇 십개의 모델과 몇 백개의 프로퍼티를 관리하려면...
무리가 있겠죠...
