EMF与XML序列化和反序列化

在进行EMF与XML序列化和反序列化遇到一些问题，最后终于解决。
首先EMF要序列化需要在ecore模型中将其EReferece的属性设置成containment为true，否则该属性无法序列化,

这点摸索了好几个小时才找到原因。

代码如下：

/**
 * 
 * @author fuliang
 *
 */
public class ModelUtil {
	public static void saveModel(Model model,String savePath) throws IOException{
		ResourceSet resourceSet = new ResourceSetImpl();
		Map<String, Object> extensionToFactoryMap = resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap();
		extensionToFactoryMap.put("xmi", new XMIResourceFactoryImpl());
		ModelPackage modelPackage = ModelPackageImpl.init();
		Registry packageRegistry = resourceSet.getPackageRegistry();
		packageRegistry.put(modelPackage.getNsURI(),modelPackage);
		Resource resource = resourceSet.createResource(URI.createFileURI(savePath));
		resource.getContents().add(model);
		resource.save(null);
	}
	
	public static Model loadModel(String path) throws IOException{
		ResourceSet resourceSet = new ResourceSetImpl();
		Map<String, Object> extensionToFactoryMap = resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap();
		extensionToFactoryMap.put("xmi", new XMIResourceFactoryImpl());
		ModelPackage modelPackage = ModelPackageImpl.init();
		Registry packageRegistry = resourceSet.getPackageRegistry();
		packageRegistry.put(modelPackage.getNsURI(),modelPackage);
		Resource resource = resourceSet.createResource(URI.createFileURI(path));
		resource.load(null);
		Wrapper wrapper = (Wrapper) resource.getContents().get(0);
		return wrapper;
	}
}

 

另外要想制定生成代码的package，需要在model.genmodel里面的Package的properties将base package设置好。
