webservice例程

1、服务端

（1）接口：

package ws1;

import java.util.List;

import javax.jws.WebService;

@WebService(name = "myService", portName = "myPort", serviceName = "myService", targetNamespace = "sun.com")
public interface IMyService {
	int add(int a, int b);

	User addUser(User user);

	List list();

	boolean login(User user);
}

package ws1;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class User {
	private Long id;
	private String name;
	private String sex;
	private Integer age;

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getSex() {
		return sex;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}

	public Integer getAge() {
		return age;
	}

	public void setAge(Integer age) {
		this.age = age;
	}

	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + ", sex=" + sex + ", age="
				+ age + "]";
	}

}

（2）实现类：

package ws1;

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

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

@WebService(name = "myService", portName = "myPort", serviceName = "myService", targetNamespace = "sun.com")
public class MyServiceImpl implements IMyService {
	private List users = new ArrayList();

	@Override
	public @WebResult(name = "res")
	int add(@WebParam(name = "a") int a, @WebParam(name = "b") int b) {
		return a + b;
	}

	@WebMethod(exclude = false)
	@Override
	public @WebResult(name = "user")
	User addUser(@WebParam(name = "user") User user) {
		users.add(user);
		return user;
	}

	@WebMethod(exclude = false)
	@Override
	public @WebResult(name = "users")
	List list() {
		return users;
	}

	@Override
	public @WebResult(name = "login")
	boolean login(@WebParam(name = "user") User user) {
		if (users.contains(user))
			return true;
		return false;
	}

}

（3）发布类

package ws1;

import javax.xml.ws.Endpoint;

public class Publish {
	public static void main(String[] args) {
		String address = "http://localhost:8888/ws";
		Object implementor = new MyServiceImpl();
		Endpoint.publish(address, implementor);
		System.out.println("发布成功。。。");
	}
}

2、客户端soap消息发送接收测试：

package ws1;

import java.io.IOException;
import java.io.StringReader;
import java.io.StringWriter;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Random;
