学习CXF WebService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

public interface IHelloWorld { }

public String sayHello(String name); public String getUserName(Users user); public List 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 = \, portName=\)

public class HelloWorldImpl implements IHelloWorld {

@Override

public String sayHello(String name) {

return name + \您好啊!\;

}

}

@Override

public String getUserName(Users user) { }

@Override

public List getListUser() { }

System.out.println(\); List list = new ArrayList(); 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;

return user.getName();

三、实体类Users

package com.ws.entity; import java.io.Serializable;

public class Users implements Serializable{

private static final long serialVersionUID = -5031894017095689998L; private Integer id; private String name; public Integer getId() { }

public void setId(Integer id) { }

public String getName() { }

public void setName(String name) { }

public Users(Integer id, String name) { }

public Users() {

super(); this.id = id; this.name = name; this.name = name; return name; this.id = id; return id;

}

}

super();

Users类如果不写默认构造方法，将报如下异常：

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;

public class DeployHelloWorldService {

protected DeployHelloWorldService() throws Exception { System.out.println(\);

HelloWorldImpl implementor = new HelloWorldImpl(); //工程名

String address = \; Endpoint.publish(address, implementor); }

/**

* @param args

* @throws Exception */

public static void main(String[] args) throws Exception {

new DeployHelloWorldService();

System.out.println(\); Thread.sleep(5 * 60 * 1000);

System.out.println(\); 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;

public final class Client {

private static final QName SERVICE_NAME = new QName(\, \); private static final QName PORT_NAME = new QName(\, \);

public static void main(String args[]) throws Exception { Service service = Service.create(SERVICE_NAME);

String endpointAddress = \

private Client() { }

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

IHelloWorld hw = service.getPort(IHelloWorld.class); System.out.println(hw.sayHello(\张述飞\

} }

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 \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！
