使用CXF框架开发webService代码

一、新建两个maven java工程，分别为ws_server  和 ws_client。

二、引用的jar包   是maven工程，pom.xml 文件内容如下：

<properties>
	<cxf.version>3.1.10</cxf.version>
	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<dependencies>
	<dependency>

		<artifactId>junit</artifactId>
		<version>3.8.1</version>
		<scope>test</scope>
	</dependency>
	<!-- hello.jar 只在客戶端引用 -->
	<dependency>
		<groupId>my</groupId>

</dependencies>

三、ws_server代码

3.1 Hello.java 接口

package com.ws_server;

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

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface Hello {
	
	@WebMethod
	public String sayHello(String userName);
	
	@WebMethod
	public List<User> getAllUser();
	
	@WebMethod
	public Map<Integer,User> getMapUser(int id);
	
	@WebMethod
	public Set<User> getSetUser(float age);
	
	@WebMethod
	public String getJsonUser();
}

3.2 HelloImpl.java     接口实现

package com.ws_server;

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

import javax.jws.WebService;

import com.alibaba.fastjson.JSONObject;

@WebService
public class HelloImpl implements Hello {
	
	static List<User> users = new ArrayList<User>();
	
	static {
		User user1 = new User(1, "张三", 12.0f);
		User user2 = new User(2, "李四", 13.0f);
		User user3 = new User(3, "王五", 14.0f);
		User user4 = new User(4, "赵六", 15.0f);
		User user5 = new User(5, "董七", 16.0f);
		users.add(user1);
		users.add(user2);
		users.add(user3);
		users.add(user4);
		users.add(user5);
	}
	
	public String sayHello(String userName) {
		System.out.println("-----server-----sayHello------"+userName);
		return "server-------return------"+userName;
	}

	public List<User> getAllUser() {
		System.out.println("-----server------getAllUser---------");
		return HelloImpl.users;
	}

	public Map<Integer, User> getMapUser(int id) {
		System.out.println("-----server------getMapUser---------"+id);
		
		Map<Integer, User> map = new HashMap<Integer, User>();
		for(int i=0; i<HelloImpl.users.size(); i++){
			if(id == users.get(i).getId()){
				map.put(id, users.get(i));
			}
		}
		return map;
	}

	public Set<User> getSetUser(float age) {
		
		System.out.println("-----server------getSetUser---------"+age);
		
		Set<User> set = new HashSet<User>();
		for(int i=0; i<HelloImpl.users.size(); i++){
			if(users.get(i).getAge() > age){
				set.add(users.get(i));
			}
		}
		return set;
	}

	public String getJsonUser() {
		System.out.println("-----server------getJsonUser---------");
		
		JSONObject jsonObject = new JSONObject();
		jsonObject.put("user", users);
		return jsonObject.toString();
	}

}

3.3 HelloServer.java   发布服务

package com.ws_server;

import javax.xml.ws.Endpoint;

import org.apache.cxf.endpoint.Server;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;

public class HelloServer {

		public static void main(String[] args) {
			//endpoint 发布方式
			Hello hello = new HelloImpl();
			String address = "http://109.52.60.41:8080/hello";
			//Endpoint.publish(address, hello);
			
			//cxf发布方式
			JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean();
			factoryBean.setAddress(address);
			factoryBean.setServiceClass(HelloImpl.class);
			factoryBean.setServiceBean(hello);
			//服务端出  和  入的日志拦截器      打印日志
			factoryBean.getInInterceptors().add(new LoggingInInterceptor());
			factoryBean.getOutInterceptors().add(new LoggingOutInterceptor());
			
			//添加自定义拦截器
			factoryBean.getInInterceptors().add(new MyInterceptor());
			
			Server server = factoryBean.create();
			server.start();
			
			System.out.println("server start");
		}
}

3.4 MyInterceptor.java   自定义拦截器  服务端

package com.ws_server;

import java.util.List;

import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

public class MyInterceptor extends AbstractPhaseInterceptor<SoapMessage> {

	public MyInterceptor() {
		super(Phase.PRE_INVOKE);
	}

	public void handleMessage(SoapMessage message) throws Fault {
		System.out.println("------MyInterceptor------");
		
		List<Header> headers = message.getHeaders();
		
		if(headers == null || headers.size() < 1){
			throw new Fault(new IllegalArgumentException("-----验证未通过-----"));
		}
		
		Header header = headers.get(0);
		
		Element element = (Element) header.getObject();
		NodeList userTemp = element.getElementsByTagName("userName");
		NodeList passwordTemp = element.getElementsByTagName("password");
		String user = userTemp.item(0).getTextContent();
		String password = passwordTemp.item(0).getTextContent();
		System.out.println("--------user------"+user);
		System.out.println("--------password------"+password);
		if(!user.equals("zhangsan") || user == null){
			throw new Fault(new IllegalArgumentException("-----用户名未通过验证-----"));
		}
		
		if(!password.equals("123456") || password == null){
			throw new Fault(new IllegalArgumentException("-----密码未通过验证-----"));
		}
		System.out.println("-------正常-------");
	}

}

3.5 User.java  POJO类

package com.ws_server;

public class User {
	private int id;
	private String name;
	private float age;
	
	public User(){
		
	}
	
	public User(int id, String name, float age) {
		super();
		this.id = id;
		this.name = name;
		this.age = age;
	}
	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 float getAge() {
		return age;
	}
	public void setAge(float age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", name=" + name + ", age=" + age + "]";
	}
	
}

4.ws_client 客户端

      将ws_server 服务端的Hello.java和User.java导出为一个hello.jar包，放到ws_client端的src/lib/目录下，在pom.xml文件中配置。

4.1 HelloClient.java   

package com.ws_client;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import com.alibaba.fastjson.JSONObject;
import com.ws_server.Hello;

public class HelloClient {
	public static void main(String[] args) {
		System.out.println("------client----");
		
		String address = "http://109.52.60.41:8080/hello";
		
		JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
		factoryBean.setAddress(address);
		factoryBean.setServiceClass(Hello.class);
		//客户端打印日志
		factoryBean.getInInterceptors().add(new LoggingInInterceptor());
		factoryBean.getOutInterceptors().add(new LoggingOutInterceptor());
		
		//客户端拦截器
		factoryBean.getOutInterceptors().add(new MyClientInterceptor());
		
		Hello hello = (Hello) factoryBean.create();
		
		System.out.println("----client-------sayHello-------");
		System.out.println(hello.sayHello("world"));
		
		System.out.println("----client-------getAllUser-------");
		System.out.println(hello.getAllUser());
		
		System.out.println("----client-------getMapUser-------");
		System.out.println(hello.getMapUser(3));
		
		System.out.println("----client-------getSetUser-------");
		System.out.println(hello.getSetUser(13.0f));
		
		System.out.println("----client-------getJsonUser-------");
		JSONObject jsonObject = JSONObject.parseObject(hello.getJsonUser());
		System.out.println(jsonObject.get("user"));
		
	}
}

4.2 MyClientInterceptor.java

package com.ws_client;

import java.util.List;

import javax.xml.namespace.QName;

import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.helpers.DOMUtils;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.w3c.dom.Document;
import org.w3c.dom.Element;

public class MyClientInterceptor extends AbstractPhaseInterceptor<SoapMessage>{

	private String userName;
	private String password;
	//准备发送时调用
	public MyClientInterceptor() {
		super(Phase.PREPARE_SEND);
		userName = "zhangsan";
		password = "123456";
	}

	@Override
	public void handleMessage(SoapMessage message) throws Fault {
		List<Header> headers = message.getHeaders();
		
		/*
		 * <soap:Header>
		 * 	<authrity>
		 * 		<userName>zhangsan</userName>
		 * 		<password>123456</password>
		 * 	</authrity>
		 * </soap:Header>
		 */
		Document document = DOMUtils.createDocument();
		
		Element auth = document.createElement("authrity");
		
		Element userName = document.createElement("userName");
		userName.setTextContent(this.userName);
		
		Element password = document.createElement("password");
		password.setTextContent(this.password);
		
		auth.appendChild(userName);
		auth.appendChild(password);
		
		headers.add(0, new Header(new QName("myClient"), auth));
	}

	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;
	}
	

}
