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.jarjetty-continuation-9.2.11.v20150529.jarjetty-http-9.2.11.v20150529.jarjetty-io-9.2.11.v20150529.jarjetty-server-9.2.11.v20150529.jarjetty-util-9.2.11.v20150529.jarwsdl4j-1.6.3.jarxmlschema-core-2.2.1.jar一、接口类IHelloWorld.javapackage com.ws.hello;import java.util.List;import javax.jws.WebService;import ers;@WebServicepublic interface 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.javapackage com.ws.hello;import java.util.ArrayList;import java.util.List;import javax.jws.WebService;import ers;@WebService(endpointInterface = "com.ws.hello.IHelloWorld",serviceName = "IHelloWorld", portName="IHelloWorldPort")public class HelloWorldImpl implements IHelloWorld {@Overridepublic String sayHello(String name) {return name + ": 您好啊!";}@Overridepublic String getUserName(Users user) {return user.getName();}@Overridepublic 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Userspackage 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() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) { = name;}public Users(Integer id, String name) {super();this.id = id;
