### 1.1、UserBean ###

package com.dgut.bean;
    
    public class UserBean {
        
    	private int id;
    	private String name;
    	private int age;
    	private String sex;
    	
    	public int getId() {
        
    		return id;
    	}
    	public void setId(int id) {
        
    		this.id = id;
    	}
    	public String getName() {
        
    		return name;
    	}
    	public void setName(String name) {
        
    		this.name = name;
    	}
    	public int getAge() {
        
    		return age;
    	}
    	public void setAge(int age) {
        
    		this.age = age;
    	}
    	public String getSex() {
        
    		return sex;
    	}
    	public void setSex(String sex) {
        
    		this.sex = sex;
    	}
    	
    }

### 1.2、UserDao ###

package com.dgut.dao;
    
    import javax.jws.WebService;
    
    import com.dgut.bean.UserBean;
    
    /* 使用@WebService注解*/
    @WebService
    public class UserDao {
        
    	
    	public UserBean findUserBeanById(int id) {
        
    		UserBean userBean=new UserBean();
    		
    		//真实开发需要连接数据库获取数据
    		userBean.setId(id);
    		userBean.setName("王二毛");
    		userBean.setAge(18);
    		userBean.setSex("男");
    		
    		return userBean;
    	}
    }

### 1.3、PublishUserService ###

package com.dgut.service;
    
    import javax.xml.ws.Endpoint;
    
    import com.dgut.dao.UserDao;
    
    public class PublishUserService {
        
    
    	public static void main(String[] args) {
        
    
    		/*
    		 * 通过Java jdk自带的类来发布webservice
    		 * 
    		 * 参数解析：
    		 * address：对外提供一个访问地址
    		 * HelloWorldDao：向外发布的类
    		 * 
    		 * 发布webservice时默认生成wsdl说明书
    		 * 通过http://localhost:8989/helloworld?wsdl访问wsdl说明书
    		 */
    		System.out.println("服务端开始发布初始化...");
    		
    		if (Endpoint.publish("http://localhost:8989/helloworld", new UserDao()) != null) {
        
    			System.out.println("服务端发布成功");
    		}
    	}
    
    }

## 二、客户端 ##

### 2.1、UrlConectionInvoke ###

package com.dgut.client;
    
    import java.io.InputStream;
    import java.io.OutputStream;
    import java.net.HttpURLConnection;
    import java.net.URL;
    
    public class UrlConectionInvoke {
        
    	public static void main(String[] args) throws Exception {
        
    
    		// 请求webservice的访问路径
    		URL url = new URL("http://localhost:8989/helloworld");
    
    		// 打开连接
    		HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
    
    		// 服务端接受POST请求
    		urlConnection.setRequestMethod("POST");
    
    		// 向服务端发送xml格式数据
    		urlConnection.setDoOutput(true);
    
    		// 接受服务端数据
    		urlConnection.setDoInput(true);
    
    		// 服务端接受的是xml格式的文件
    		urlConnection.setRequestProperty("Content-Type", "text/xml;charset=utf-8");
    
    		// 通过流来写数据到服务端
    		OutputStream outputStream = urlConnection.getOutputStream();
    
    		// 实例化一个buffer
    		StringBuffer buffer = new StringBuffer();
    
    		// 添加
    		buffer.append(
    				"<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:q0=\"http://dao.dgut.com/\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">")
    				.append("<soapenv:Body><q0:findUserBeanById><org0>2</org0></q0:findUserBeanById></soapenv:Body></soapenv:Envelope>");
    
    		// 向服务端写数据
    		outputStream.write(buffer.toString().getBytes());
    
    		// 接受服务端传回的数据
    		InputStream inputStream = urlConnection.getInputStream();
    		byte[] b = new byte[1024];
    
    		int length = 0;
    
    		StringBuffer sb = new StringBuffer();
    
    		while ((length = inputStream.read(b)) != -1) {
        // 等于-1说明已经读完
    			String s = new String(b, 0, length);
    			sb.append(s);
    		}
    
    		System.out.println(sb.toString());
    	}
    }
