5.3、运用BIRT API创建Table

5.3、使用BIRT API创建Table

    在使用BIRT API前，得先配置一下BIRT的环境，也就是Birt -Runtime,使用是需要用到BIRT-runtime文件夹下的ReportEngine文件夹下的内容。

    如果都准备好了，那就开始吧

    先新建一个Java项目，比如JavaBirtExample，添加依赖的jar文件，因为BIRT基于OSGI的，所以org.eclipse.equinox.common这个文件是一定要的，如果要用到图表的话还需要emf对应的文件。

public class CreateTableReport {

	public static final String BIRT_HOME = "D:/DeveloperTools/birt-runtime-2_3_1/ReportEngine";
	
	public static void createReport() throws Exception {
		DesignConfig designConfig = new DesignConfig();
		designConfig.setBIRTHome(BIRT_HOME);

			Platform.startup(designConfig);
			String extensionId = IDesignEngineFactory.EXTENSION_DESIGN_ENGINE_FACTORY;
			IDesignEngineFactory factory = (IDesignEngineFactory)Platform.createFactoryObject(extensionId);

		}catch (Exception e) {
			e.printStackTrace();
		}
		
		SessionHandle sessionHandle = designEngine.newSessionHandle(ULocale.CHINESE);
		
		ReportDesignHandle designHandle = sessionHandle.createDesign();
		
		ElementFactory elementFactory = designHandle.getElementFactory();
		
		DesignElementHandle elementHandle = elementFactory.newSimpleMasterPage("Page Master");
		designHandle.getMasterPages().add(elementHandle);
		
		TableHandle tableHandle = elementFactory.newTableItem(null, 3, 1, 1, 0);
		tableHandle.setWidth("100%");
		designHandle.getBody().add(tableHandle);

		labelHandle = elementFactory.newLabel(null);
		labelHandle.setText("343206");
		detailCellHandle.getContent().add(labelHandle);
		

		SharedStyleHandle styleHandle = elementFactory.newStyle("MyStyle");
		styleHandle.getBorderTopWidth().setValue(1);
		styleHandle.getBorderBottomWidth().setValue(1);
		styleHandle.getBorderLeftWidth().setValue(1);
		styleHandle.getBorderRightWidth().setValue(1);
		styleHandle.setTextAlign(DesignChoiceConstants.TEXT_ALIGN_CENTER);
		styleHandle.setProperty(IStyleModel.BORDER_TOP_STYLE_PROP, DesignChoiceConstants.LINE_STYLE_GROOVE);

		styleHandle.setProperty(IStyleModel.BORDER_RIGHT_STYLE_PROP, DesignChoiceConstants.LINE_STYLE_GROOVE);
		designHandle.getStyles().add(styleHandle);
		
		for(int i = 0;i<tableHandle.getColumnCount();i++) {
			ColumnHandle colHandle = (ColumnHandle)tableHandle.getColumns().get(i);
			colHandle.setStyle(styleHandle);
		}
		
		File file = new File("c:/temp/TableReport.rptdesign");
		if(!file.exists()) 
			file.createNewFile();
		designHandle.saveAs(file.toString());
		designHandle.close();
		System.out.println("创建成功！");
	}
	
	public static void main(String[] args) {
		try {
			createReport();
		}catch (Exception e) {
			e.printStackTrace();
		}
	}
}

 

执行之后，会在c:/temp目录下面创建一个TableReport.rptdesign文件，预览一下结果为：
