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

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")
publicclassHelloWorldImpl 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 Usersimplements Serializable{
privatestaticfinallongserialVersionUID = -5031894017095689998L;
private Integerid;
private Stringname;
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;
importjava.net.URL;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import javax.xml.ws.soap.SOAPBinding;
importcom.ws.entity.Users;
importcom.ws.hello.HelloWorldImpl;
import com.ws.hello.IHelloWorld;
publicfinalclass Client {
privatestaticfinal QNameSERVICE_NAME =new QName("http://hello.ws.com/","IHelloWorld");
privatestaticfinal QNamePORT_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!
