操作循序：

此顺序基于契约优先原则，在我之前写过的webservice（六）的基础上进行修改

1.将wsdl拷贝到webContent下的WEB-INF中（导入JAX-RI包）
??? ?在wsdl中就可以使用include方式来导入了(暂时先不要进行导入，经测试发现导入可能引发问题)
??? ?修改实现类中的wsdlLocation的目录名
2.在web-inf下创建一个文件名为：sun-jaxws.xml
?? ?并进行如下修改：
?? ?<?xml version="1.0" encoding="UTF-8"?>
?? ?<endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"
?? ??? ?version="2.0">
?? ??? ?<!-- 1.Servlet中所需要对应的名称2.实现类3.浏览器的后缀 -->
?? ??? ?<endpoint name="UserService" implementation="cn.edu.zttc.service.UserServiceImpl"
?? ??? ??? ?url-pattern="/us" />
?? ?</endpoints>
3.配置web.xml
?? ?加入监听器
?? ?? <listener>
?? ? ??? ?<listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
?? ?? </listener>
?? ?? <servlet>
?? ? ??? ?<servlet-name>UserService</servlet-name>
?? ? ??? ?<servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
?? ?? </servlet>
?? ?? <servlet-mapping>
?? ? ??? ?<servlet-name>UserService</servlet-name>
?? ? ??? ?<url-pattern>/us</url-pattern>
?? ?? </servlet-mapping>


具体实例如下：

服务器端：

生成IUserService 

package cn.edu.zttc.service;

    @WebMethod

    @ResponseWrapper(localName = "addResponse",className = "cn.edu.zttc.service.AddResponse")

        User user)

    @ResponseWrapper(localName = "loginResponse",className = "cn.edu.zttc.service.LoginResponse")
    public User login(
        @WebParam(name = "username",targetNamespace = "")
        String username,@WebParam(name = "password",targetNamespace = "")
        String password)
        throws UserRunTimeException
    ;

}

实现类 

package cn.edu.zttc.service;

import java.util.List;

import javax.jws.WebService;

import org.zttc.dao.UserDao;
import org.zttc.dao.UserRunTimeException;
import org.zttc.vo.User;

@WebService(endpointInterface="cn.edu.zttc.service.IUserService",wsdlLocation="WEB-INF/wsdl/user.wsdl",serviceName="UserService",portName="userServicePort",targetNamespace="http://service.zttc.edu.cn")
public class UserServiceImpl implements IUserService {
	private UserDao userDao = UserDao.newInstence();
	@Override
	public void add(User user) throws UserRunTimeException {
		userDao.add(user);
	}

	@Override
	public void delete(String username) {
		userDao.delete(username);
	}

	@Override
	public List<User> list() {
		return userDao.list();
	}

	@Override
	public User login(String username,String password) throws UserRunTimeException {
		return userDao.login(username,password);
	}
}

DAO方法 

package org.zttc.dao;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;

import org.zttc.vo.User;

public class UserDao {
	private static final Map<String,User> users = new HashMap<String,User>();
	private static UserDao dao = null;
	public UserDao(){
		users.put("admin",new User("admin","admin","超级管理员"));
		
	}
	public static UserDao newInstence(){
		if (null==dao)dao = new UserDao();
		return dao;
	}

	public void add(User user) throws UserRunTimeException{
		System.out.println("---------add--------"+user);
		System.out.println("---------user.getUsername()--------"+user.getUsername());
		if (users.containsKey(user.getUsername())) {
			 throw new UserRunTimeException("用户已存在");
		}
		users.put(user.getUsername(),user);
	}
	public void delete(String username){
		System.out.println("---------delete--------"+username);
		users.remove(username);
	}
	public List<User> list(){
		System.out.println("---------list--------"+users);
		Set<String> keys = users.keySet();
		List<User> list = new ArrayList<User>();
		for (String key : keys) {
			list.add(users.get(key));
		}
		return list;
	}
	public User login(String username,String password) throws UserRunTimeException{
		System.out.println("---------login--------"+username+password);
		if (!users.containsKey(username)) {
			 throw new UserRunTimeException("用户不存在");
		}
		User u = users.get(username);
		if (!password.equals(u.getPassword())) {
			 throw new UserRunTimeException("用户密码不正确");
		}
		return u;
	}
}

填写异常类 

package org.zttc.dao;

/**
 * 继承RunTimeException会在服务器端抛出异常
 * 所以要继承为Exception
 */
public class UserRunTimeException extends Exception {
	private static final long serialVersionUID = 1L;

	public UserRunTimeException() {
		super();
	}

	public UserRunTimeException(String arg0,Throwable arg1,boolean arg2,boolean arg3) {
		super(arg0,arg1,arg2,arg3);
	}

	public UserRunTimeException(String arg0,Throwable arg1) {
		super(arg0,arg1);
	}

	public UserRunTimeException(String arg0) {
		super(arg0);
	}

	public UserRunTimeException(Throwable arg0) {
		super(arg0);
	}

}

实体类 

package org.zttc.vo;

public class User {
	private String username;
	private String password;
	private String nickname;
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getNickname() {
		return nickname;
	}
	public void setNickname(String nickname) {
		this.nickname = nickname;
	}
	public User(String username,String password,String nickname) {
		super();
		this.username = username;
		this.password = password;
		this.nickname = nickname;
	}
	public User() {
		super();
	}

}
