Webservice_15_SOAP异常处理

非常感谢孙浩老师。

自定义异常类：UserException

package cn.lichen.soap;

public class UserException extends Exception {

	/** 
	* @Fields serialVersionUID : TODO
	*/ 
	private static final long serialVersionUID = 1L;

	public UserException() {
		// TODO Auto-generated constructor stub
	}

	public UserException(String message) {
		super(message);
		// TODO Auto-generated constructor stub
	}

	public UserException(Throwable cause) {
		super(cause);
		// TODO Auto-generated constructor stub
	}

	public UserException(String message,Throwable cause) {
		super(message,cause);
		// TODO Auto-generated constructor stub
	}

	public UserException(String message,Throwable cause,boolean enableSuppression,boolean writableStackTrace) {
		super(message,cause,enableSuppression,writableStackTrace);
		// TODO Auto-generated constructor stub
	}

}

接口：IMyService

@WebResult(name = "user")
	public User login(@WebParam(name = "username") String username,@WebParam(name = "password") String password) throws UserException;

?

实现：MyServiceImpl

@Override
	public User login(String username,String password) throws UserException {
		for(User user:users) {
			if(username.equals(user.getUsername())&&password.equals(user.getPassword()))
				return user;
		}
		throw new UserException("用户不存在"); 

?

测试方法：

/**
	 * @Title: test07
	 * @Description: SOAP处理异常
	 * @param
	 * @return void
	 * @throws
	 */
	@Test
	public void test07() {
		try {
			// 创建访问wsdl服务的URL
			URL url = new URL("http://localhost:9999/ns?wsdl");
			// 通过Qname指明服务的具体信息
			QName name = new QName("http://soap.lichen.cn/","MyServiceImplService");
			// 创建service
			Service service = Service.create(url,name);

			// 创建dispatch
			Dispatch<SOAPMessage> dispatch = service.createDispatch(new QName(
					"http://soap.lichen.cn/","MyServiceImplPort"),SOAPMessage.class,Service.Mode.MESSAGE);

			// 创建SOAPmessage
			SOAPMessage message = MessageFactory.newInstance().createMessage();
			SOAPEnvelope envelope = message.getSOAPPart().getEnvelope();
			SOAPBody body = envelope.getBody();
			
			QName qname = new QName("http://soap.lichen.cn/","login","xsd");
			SOAPBodyElement bodyElement = body.addBodyElement(qname);
			bodyElement.addChildElement("username").setValue("aaa");
			bodyElement.addChildElement("password").setValue("bbb");
			// 输入创建SOAPmessage
			message.writeTo(System.out);

			System.out.println("nn" + "-----------invoking-------------"
					+ "n");

			// 传递消息并且得到结果
			SOAPMessage responseMessage = dispatch.invoke(message);

			// 输出得到的SOAPmessage
			responseMessage.writeTo(System.out);

		} catch (SOAPException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

客户端控制台报异常，显示消息：

修改实现方法扑获的异常：

@Override
	public User login(String username,String password) throws UserException {
		for(User user:users) {
			if(username.equals(user.getUsername())&&password.equals(user.getPassword()))
				return user;
		}
		throw new RuntimeException("用户不存在"); 
	}

?

由于wsd中的声明的异常类型为UserException，

?

如果为UserException，服务器发现此类型，所以服务器不会报异常，但会返回客户端异常。

当报异常RuntimeException时，服务器没有发现此类型，所以服务器报异常，同时会返回客户端异常。

?

使用wsimport导出服务端Java文件，创建客户端。会产生UserException_Exception.java。

测试方法：TestClient

package cn.lichen.soap;

public class TestClient {

	public static void main(String[] args) {
		MyServiceImplService mis = new MyServiceImplService();
		IMyService ms = mis.getMyServiceImplPort();
		try {
			ms.login("admin","34545");
		} catch (UserException_Exception e) {
			System.out.println(e.getMessage());
		}
	}
}

客户端异常:
