如何用Eclipse API 提供的 org.eclipse.wst.wsdl 去解析读取WSDL文件？

标签：blog   http   io   ar   os   使用   sp   java   for   

相对来说，Eclipse API的中文资料比较少，但是Eclipse的API提供了非常多的，非常强大的功能。

比如，eclipse的Eclipse API 提供的 org.eclipse.wst.wsdl包，里面提供了很多的类去解析WSDL文件。

总体来说，其提供的API简单易懂，而且其API是和专业术语对应起来的,比如，

(子节点) Port - 定义为协议/数据格式绑定与具体Web访问地址组合的单个服务访问点。

下面是代码实例：

import java.io.File;
import java.io.IOException;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Set;

import javax.wsdl.Message;
import javax.wsdl.Part;
import javax.wsdl.PortType;
import javax.xml.namespace.QName;

import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
import org.eclipse.wst.wsdl.Definition;
import org.eclipse.wst.wsdl.Types;
import org.eclipse.wst.wsdl.internal.impl.PartImpl;
import org.eclipse.wst.wsdl.internal.util.WSDLResourceFactoryImpl;
import org.eclipse.wst.wsdl.util.WSDLResourceImpl;
import org.eclipse.xsd.XSDElementDeclaration;
import org.eclipse.xsd.XSDSchema;
import org.eclipse.xsd.util.XSDResourceImpl;
import org.junit.Test;
import org.junit.Before;

public class WSDLParserWithEclipse {
	Definition definition=null;
	String wsdlPathString="E:/HelloEclipse-EMF-WSDL-XSD/test.wsdl";
	
	@Before
	public void setup(){
		ResourceSet resourceSet = new ResourceSetImpl();
		Resource.Factory.Registry registry = resourceSet.getResourceFactoryRegistry();
		Map extensionToFactoryMap = registry.getExtensionToFactoryMap();
		extensionToFactoryMap.put("wsdl", new WSDLResourceFactoryImpl());
		File wsdlFile =new File(wsdlPathString);  
		URI uri = URI.createFileURI(wsdlFile.getAbsolutePath());
		// You can avoid this cast, but will have to cast anyway later to get the Definition out the resource contents
		WSDLResourceImpl wsdlResource = (WSDLResourceImpl) resourceSet.createResource(uri);
		try {
			wsdlResource.load(null);
			definition = wsdlResource.getDefinition();
		}catch(Exception e){
			e.printStackTrace();
		}
	}
	
	
    @Test
    public void testTypes(){
    	Types types = definition.getETypes();
    	List schemas = types.getSchemas("http://www.xxxxx.com/problem");
		XSDSchema schema = (XSDSchema) schemas.get(0);
    	org.eclipse.xsd.util.XSDResourceImpl.serialize(System.out, schema.getElement());
    }
    
    @Test 
    public void testMessage(){
    	Map messages=definition.getMessages();
    	System.out.println("The message size is:"+messages.size());
    	Set setMessages=messages.keySet();
		Iterator iteratorMessages=setMessages.iterator();
		while(iteratorMessages.hasNext()){
			QName key=(QName)iteratorMessages.next();
			Message message=(Message)messages.get(key);
			//{http://www.xxxxx.com/problem}getKeysSoapIn
			//System.out.println("Message Name:"+message.getQName());
			if(message.getQName().toString().indexOf("getKeysSoapIn")>0){
				System.out.println("Message Name:"+message.getQName());
				Map partsMap=message.getParts();
				//org.eclipse.xsd.impl.XSDElementDeclarationImpl
				System.out.println("Message Part size for getKeysSoapIn message is:"+partsMap.size());
				PartImpl part= (PartImpl)partsMap.get("problem");
				XSDElementDeclaration xsdElementDeclaration=part.getElementDeclaration();
				XSDResourceImpl.serialize(System.out, xsdElementDeclaration.getElement());
			}		
		}
    }
    @Test 
    public void testPortType(){
    	Map portTypes=definition.getPortTypes();
		System.out.println("Port Type size:"+portTypes.size());
		if(portTypes!=null&&portTypes.size()>0){
			Set set=portTypes.keySet();
			Iterator iterator=set.iterator();
			while(iterator.hasNext()){
				QName object=(QName)iterator.next();
				PortType portType=(PortType)portTypes.get(object);
				System.out.println("Port Type name:"+portType.getQName());
				org.eclipse.xsd.util.XSDResourceImpl.serialize(System.out, portType.getDocumentationElement());
			}
		}
    }
