CXF Web Service入门实例一

最近开发开始学习Web Service，如果你是大神，请路过！谢谢！遵循前辈大神们的教导~~~，内事不决问度娘，外事不决问谷歌（现在谷歌已经不能用了），只能问度娘了！上网一百度，套用周董的一句歌词，霍，霍，霍，霍，这么多的套路(axis,axis2,XFire,CXF等)，我到底选择哪一个？因为要和Spring进行对接，看了一下，CXF与Spring的耦合度最好，于是就选择了CXF。上官网下jar包，下了最新的apache-cxf-3.1.4.zip包。解压出来，看看里面的最简单的实例，apache-cxf-3.1.4\samples\java_first_jaxws，本着你快乐所以我快乐加上不要脸的原则，我抄抄抄，改了一下名字，开发环境jdk1.6, jdk1.5没试过，上眼呐！

新建工程mywbs，导入jar包

 

cxf-core-3.1.4.jar

jetty-continuation-9.2.11.v20150529.jar

jetty-http-9.2.11.v20150529.jar

jetty-io-9.2.11.v20150529.jar

jetty-server-9.2.11.v20150529.jar

jetty-util-9.2.11.v20150529.jar

wsdl4j-1.6.3.jar

xmlschema-core-2.2.1.jar

 

一、接口类IHelloWorld.java

package com.ws.hello;

import java.util.List;

import javax.jws.WebService;

import com.ws.entity.Users;

@WebService

publicinterface IHelloWorld {

public String sayHello(String name);

public String getUserName(Users user);

public List<Users> getListUser();

}

 

二、实现类（说明endpointInterface = "com.ws.hello.IHelloWorld"，IHelloWorld类加上路径，此处注意）HelloWorldImpl.java

package com.ws.hello;

import java.util.ArrayList;

import java.util.List;

import javax.jws.WebService;

import com.ws.entity.Users;

@WebService(endpointInterface = "com.ws.hello.IHelloWorld",serviceName = "IHelloWorld", portName="IHelloWorldPort")

publicclass HelloWorldImpl implements IHelloWorld {

 

@Override

public String sayHello(String name) {

return name + ": 您好啊!";

}

 

@Override

public String getUserName(Users user) {

return user.getName();

}

 

@Override

public List<Users> getListUser() {

System.out.println("getListUser called~~~");

List<Users> list = new ArrayList<Users>();

list.add(new Users(2,"张三"));

list.add(new Users(3, "十八罗汉"));

list.add(new Users(4,"五王"));

return list;

}

 

}

 

三、实体类Users

package com.ws.entity;

import java.io.Serializable;

publicclass Users implements Serializable{

privatestaticfinallongserialVersionUID = -5031894017095689998L;

private Integer id;

private String name;

public Integer getId() {

returnid;

}

publicvoid setId(Integer id) {

this.id = id;

}

public String getName() {

returnname;

}

publicvoid setName(String name) {

this.name = name;

}

public Users(Integer id, String name) {

super();

this.id = id;

this.name = name;

}

public Users() {

super();

}

}

 

 

Users类如果不写默认构造方法，将报如下异常：

Exception in thread "main" javax.xml.ws.WebServiceException: Unable to create JAXBContext

晕了，真是崩溃了，就写了这么几句话！错误代码比正常代码还要多！真是婶婶能忍叔叔不能忍，虽然英语很烂，连猜带蒙吧，看黑色的一句话，大概似乎是告诉我们Users类中没有默认的构造方法，果断加上，错误消失！此处应有掌声！鼓掌！！！

 

四、DeployHelloWorldService.java

 

package com.ws.deploy;

import javax.xml.ws.Endpoint;

import com.ws.hello.HelloWorldImpl;

 

publicclass DeployHelloWorldService {

protected DeployHelloWorldService() throws Exception {

System.out.println("Starting Server");

HelloWorldImpl implementor = new HelloWorldImpl();

//工程名

String address = "http://localhost:8080/mywbs";

Endpoint.publish(address, implementor);

}

 

/**

* @param args

* @throws Exception

*/

publicstaticvoid main(String[] args) throws Exception {

new DeployHelloWorldService();

System.out.println("Server ready...");

Thread.sleep(5 * 60 * 1000);

System.out.println("Server exiting");

System.exit(0);

}

 

}

 

点击运行，正常的话会有

Starting Server

Server ready...

 

在IE地址栏中输入：http://localhost:8080/mywbs?wsdl

什么你不知道IE地址栏在哪里，对不起，大哥，地球是危险的，你回火星去吧！如果正常的话呢，大约在网页上会出现下面的信息，只截取一部分，注意画粗红线的地方，下面我们用的到。

五、客户端类(http://hello.ws.com/,这个就是上面画粗红线的地方)

package com.ws.client;

import java.net.URL;

 

import javax.xml.namespace.QName;

import javax.xml.ws.Service;

import javax.xml.ws.soap.SOAPBinding;

 

import com.ws.entity.Users;

import com.ws.hello.HelloWorldImpl;

import com.ws.hello.IHelloWorld;

 

publicfinalclass Client {

privatestaticfinal QName SERVICE_NAME = new QName("http://hello.ws.com/", "IHelloWorld");

privatestaticfinal QName PORT_NAME = new QName("http://hello.ws.com/", "IHelloWorldPort");

 

 

private Client() {

 

}

 

publicstaticvoid main(String args[]) throws Exception {

Service service = Service.create(SERVICE_NAME);

String endpointAddress = "http://localhost:8080/mywbs";

service.addPort(PORT_NAME, SOAPBinding.SOAP11HTTP_BINDING, endpointAddress);

 

IHelloWorld hw = service.getPort(IHelloWorld.class);

System.out.println(hw.sayHello("张述飞"));

 

/**

URL url = new URL("http://localhost:8080/mywbs?wsdl");

Service service = Service.create(url,SERVICE_NAME);

 

IHelloWorld hw = service.getPort(IHelloWorld.class);

System.out.println(hw.sayHello("张述飞"));

 

System.out.println(hw.getUserName(new Users(1,"kaka")));

for(Users user : hw.getListUser()) {

System.out.println("List User [id:"+user.getId()+"][name:"+user.getName()+"]");

}*/

 

}

}

 

这样写点击运行的话，不知道为什么会报异常，如果有不报异常的话，请贴出来，谢谢！

Exception in thread "main" javax.xml.ws.WebServiceException: WSDL Metadata not available to create the proxy, either Service instance or ServiceEndpointInterface com.ws.hello.IHelloWorld should have WSDL information

将上面紫色代码注释，运行蓝色代码正常！这是小白我学习webservice的第一个程序，不知道为什么都是坑啊，一步一个坑，难道是坑坑更健康？将代码贴出来，希望有用到的或者要学习的小白们能少走一段弯路！本来想把工程给免费发布出来，后来想想还是算了吧，小白们还是手把手的配置一下吧！
