SOAP异常处理

接口

package com.hqh.soap;
import java.util.List;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;

//如果要指定命名空间，那么接口与实现类要显示定义相同的targetNamespace！
@WebService
public interface IMyService {
	
	//服务端可能会抛出Exception，客户端调用如果出错则抛出异常
	@WebResult(name="user")
	public User login(@WebParam(name="username")String username,
					  @WebParam(name="pwd")String pwd) throws UserException;
	
}	

实现类

package com.hqh.soap;

import java.util.ArrayList;
import java.util.List;

import javax.jws.WebService;

@WebService(endpointInterface="com.hqh.soap.IMyService")
public class MyServiceImpl implements IMyService {

	private static List<User> users = new ArrayList<User>();
	
	public MyServiceImpl() {
		users.add(new User(1,"admin","admin"));
	}
	
	@Override
	public User login(String username, String pwd) throws UserException {
		for(User user:users) {
			if(username.equals(user.getName()) && pwd.equals(user.getPwd()))
				return user;
		}
		//这里抛出的异常类型如果与接口中声明的异常类型一致，那么服务端将不抛出此异常，而是直接通过soap message将异常传递到客户端
		throw new UserException("用户不存在");
		//抛出运行时异常与接口声明的异常不同，服务端会自己抛出异常，客户端也能接收到异常信息
//		throw new RuntimeException("用户不存在");
	}

}

服务端开启服务

package com.hqh.soap;

import javax.xml.ws.Endpoint;

public class MyServer {
	public static void main(String[] args) {
		String address = "http://localhost:8888/ms";
		IMyService implementor = new MyServiceImpl();
		Endpoint.publish(address, implementor);
	}
}

客户端通过wsimport命令将wsdl转换为本地java文件

package com.hqh.soap.test;

import static org.junit.Assert.*;

import com.hqh.soap.IMyService;
import com.hqh.soap.MyServiceImplService;
import com.hqh.soap.UserException_Exception;


public class Test {

	@org.junit.Test
	public void test() {
		MyServiceImplService serviceImpl = new MyServiceImplService();
		//获取服务接口
		IMyService service = serviceImpl.getMyServiceImplPort();
		try {
			service.login("za", "123");
		} catch (UserException_Exception e) {
			//e.printStackTrace();
			System.out.println(e.getMessage());
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}
