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

jetty-continuation-9.2.11.v20150529.jar
jetty-http-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：

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！
