一、利用jdk web服務api實現,這裡使用基於 SOAP message 的 Web 服務
1.首先建立一個Web services EndPoint：
Java代碼
package Hello;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.xml.ws.Endpoint;
@WebService
public class Hello {
@WebMethod
public String hello(String name) {
return "Hello, " name "n";
}
public static void main(String[] args) {
// create and publish an endpoint
Hello hello = new Hello();
Endpoint endpoint = Endpoint.publish("http://localhost:8080/hello", hello);
}
}
package Hello;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.xml.ws.Endpoint;
@WebService
public class Hello {
@WebMethod
public String hello(String name) {
return "Hello, " name "n";
}
public static void main(String[] args) {
// create and publish an endpoint
Hello hello = new Hello();
Endpoint endpoint = Endpoint.publish("http://localhost:8080/hello", hello);
}
}
2.使用 apt 編譯 Hello.java(例：apt -d [存放編譯后的文件目錄] Hello.java ) ,會生成 jaws目錄
3.使用java Hello.Hello運行,然後將瀏覽器指向http://localhost:8080/hello?wsdl就會出現下列顯示
4.使用wsimport 生成客戶端
使用如下：wsimport -p . -keep http://localhost:8080/hello?wsdl
5.客戶端程序：
Java代碼
class HelloClient{
public static void main(String args[]) {
HelloService service = new HelloService();
Hello helloProxy = service.getHelloPort();
String hello = helloProxy.hello("你好");
System.out.println(hello);
}
}
class HelloClient{
public static void main(String args[]) {
HelloService service = new HelloService();
Hello helloProxy = service.getHelloPort();
String hello = helloProxy.hello("你好");
System.out.println(hello);
}
}
二、使用xfire,我這裡使用的是myeclipse集成的xfire進行測試的
利用xfire開發WebService,可以有三種方法：
1一種是從javabean 中生成；
2 一種是從wsdl文件中生成；
3 還有一種是自己建立webservice
步驟如下：
用myeclipse建立webservice工程,目錄結構如下：
首先建立webservice介面,
代碼如下：
Java代碼
package com.myeclipse.wsExample;
//Generated by MyEclipse
public interface IHelloWorldService {
public String example(String message);
}
package com.myeclipse.wsExample;
//Generated by MyEclipse
public interface IHelloWorldService {
public String example(String message);
}
Java代碼
package com.myeclipse.wsExample;
//Generated by MyEclipse
public class HelloWorldServiceImpl implements IHelloWorldService {
public String example(String message) {
return message;
}
}
package com.myeclipse.wsExample;
//Generated by MyEclipse
public class HelloWorldServiceImpl implements IHelloWorldService {
public String example(String message) {
return message;
}
}
修改service.xml 文件,加入以下代碼：
Xml代碼
<service>
<name>HelloWorldService</name>
<serviceClass>
com.myeclipse.wsExample.IHelloWorldService
</serviceClass>
<implementationClass>
com.myeclipse.wsExample.HelloWorldServiceImpl
</implementationClass>
<style>wrapped</style>
<use>literal</use>
<scope>application</scope>
</service>
<service>
<name>HelloWorldService</name>
<serviceClass>
com.myeclipse.wsExample.IHelloWorldService
</serviceClass>
<implementationClass>
com.myeclipse.wsExample.HelloWorldServiceImpl
</implementationClass>
<style>wrapped</style>
<use>literal</use>
<scope>application</scope>
</service>
把整個項目部署到tomcat伺服器中 ,打開瀏覽器,輸入http://localhost:8989/HelloWorld/services/HelloWorldService?wsdl
客戶端實現如下：
Java代碼
package com.myeclipse.wsExample.client;
import java.net.MalformedURLException;
import java.net.URL;
import org.codehaus.xfire.XFireFactory;
import org.codehaus.xfire.client.Client;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import com.myeclipse.wsExample.IHelloWorldService;
public class HelloWorldClient {
public static void main(String[] args) throws MalformedURLException, Exception {
// TODO Auto-generated method stub
Service s=new ObjectServiceFactory().create(IHelloWorldService.class);
XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire());
String url="http://localhost:8989/HelloWorld/services/HelloWorldService";
try
{
IHelloWorldService hs=(IHelloWorldService) xf.create(s,url);
String st=hs.example("zhangjin");
System.out.print(st);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
package com.myeclipse.wsExample.client;
import java.net.MalformedURLException;
import java.net.URL;
import org.codehaus.xfire.XFireFactory;
import org.codehaus.xfire.client.Client;
import org.codehaus.xfire.client.XFireProxyFactory;
import org.codehaus.xfire.service.Service;
import org.codehaus.xfire.service.binding.ObjectServiceFactory;
import com.myeclipse.wsExample.IHelloWorldService;
public class HelloWorldClient {
public static void main(String[] args) throws MalformedURLException, Exception {
// TODO Auto-generated method stub
Service s=new ObjectServiceFactory().create(IHelloWorldService.class);
XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire());
String url="http://localhost:8989/HelloWorld/services/HelloWorldService";
try
{
IHelloWorldService hs=(IHelloWorldService) xf.create(s,url);
String st=hs.example("zhangjin");
System.out.print(st);
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
這裡再說點題外話,有時候我們知道一個wsdl地址,比如想用java客戶端引用.net 做得webservice,使用myeclipse引用,但是卻出現無法通過驗證的錯誤,這時我們可以直接在類中引用,步驟如下：
Java代碼
public static void main(String[] args) throws MalformedURLException, Exception {
// TODO Auto-generated method stub
Service s=new ObjectServiceFactory().create(IHelloWorldService.class);
XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire());
//遠程調用.net開發的webservice
Client c=new Client(new URL("http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx?wsdl"));
Object[] o=c.invoke("qqCheckOnline", new String[]{"531086641","591284436"});
//調用.net本機開發的webservice
Client c1=new Client(new URL("http://localhost/zj/Service.asmx?wsdl"));
Object[] o1=c1.invoke("HelloWorld",new String[]{});
}
public static void main(String[] args) throws MalformedURLException, Exception {
// TODO Auto-generated method stub
Service s=new ObjectServiceFactory().create(IHelloWorldService.class);
XFireProxyFactory xf=new XFireProxyFactory(XFireFactory.newInstance().getXFire());
//遠程調用.net開發的webservice
Client c=new Client(new URL("http://www.webxml.com.cn/webservices/qqOnlineWebService.asmx?wsdl"));
Object[] o=c.invoke("qqCheckOnline", new String[]{"531086641","591284436"});
//調用.net本機開發的webservice
Client c1=new Client(new URL("http://localhost/zj/Service.asmx?wsdl"));
Object[] o1=c1.invoke("HelloWorld",new String[]{});
}
