soap中自定义异常处理
创建服务器端
1.创建一个接口
IMyService.java
package com.test.service;import java.util.List;import javax.jws.WebParam;import javax.jws.WebResult;import javax.jws.WebService;@WebService(targetNamespace = "http://www.webservice.com")public interface IMyService {// 异常处理@WebResult(name = "user")public User login(@WebParam(name = "username") String username, @WebParam(name = "password") String password) throws UserException;}?
2.创建实现接口的类
MyServiceImpl.java
package com.test.service;import java.util.ArrayList;import java.util.List;import javax.jws.WebService;@WebService(endpointInterface = "com.test.service.IMyService", targetNamespace = "http://www.webservice.com")public class MyServiceImpl implements IMyService {private static List<User> users = new ArrayList<User>();public MyServiceImpl() {users.add(new User(1, "admin", "管理员", "111111"));}@Overridepublic 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("用户名或密码不正确！");}}?
3.自定义异常类
UserException.java
package com.test.service;public class UserException extends Exception {public UserException() {super();}public UserException(String message, Throwable cause) {super(message, cause);}public UserException(String message) {super(message);}public UserException(Throwable cause) {super(cause);}}?
4.开启服务
MyServer.java
package com.test.service;import javax.xml.ws.Endpoint;public class MyServer {public static void main(String[] args) {String address = "http://localhost:9999/server";// 发布服务的实现类Endpoint.publish(address, new MyServiceImpl());}}?
5.测试类TestSoap.java
// 异常处理@Testpublic void test05() {try {// 创建服务URL url = new URL("http://localhost:9999/server");QName qname = new QName("http://www.webservice.com", "MyServiceImplService");Service service = Service.create(url, qname);// 创建DispatchDispatch<SOAPMessage> dispatch = service.createDispatch(new QName("http://www.webservice.com", "MyServiceImplPort"), SOAPMessage.class, Service.Mode.MESSAGE);// 创建SOAP的body消息SOAPMessage message = MessageFactory.newInstance().createMessage();SOAPBody body = message.getSOAPPart().getEnvelope().getBody();// 根据QName创建相应的节点QName ename = new QName("http://www.webservice.com", "login", "ns");SOAPBodyElement element = body.addBodyElement(ename);element.addChildElement("username").setValue("cdxs");element.addChildElement("password").setValue("123");message.writeTo(System.out);System.out.println("\n invoking...");// 通过dispatch传递消息，返回响应消息SOAPMessage response = dispatch.invoke(message);response.writeTo(System.out);System.out.println();} catch (SOAPException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (SOAPFaultException e) {System.out.println(e.getMessage());}}?
运行结果：
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"><SOAP-ENV:Header/><SOAP-ENV:Body><ns:login xmlns:ns="http://www.webservice.com"><username>cdxs</username><password>123</password></ns:login></SOAP-ENV:Body></SOAP-ENV:Envelope>
