又一HelloWorld示例,老套的HelloWorld是入门经典。也是基础和必须掌握的,下面看看HelloWorldWebService,很简单。
需要的jar包如下:
1、 HelloWorldService服务器端代码
package com.hoo.service;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
/**
* <b>function:</b>CXF WebService 服务器端helloWorld示例
* @author hoojo
* @createDate 2011-3-16 上午08:29:07
* @file HelloWorld.java
* @package com.hoo.service
* @project CXFWebService
* @blog http://blog.csdn.net/IBM_hoojo
* @email [email protected]
* @version 1.0
*/
@WebService
@SOAPBinding(style = Style.RPC)
public class HelloWorldService {
public String sayHello(@WebParam(name = "name") String name) {
return name + " say: Hello World ";
}
}
要说明的是,上面的服务器端代码运用了JDK5的新特性Annotation,这个非常好用。
需要注意的是,如果不添加@SOAPBinding(style = Style.RPC)注解,将会出现异常:
com.sun.xml.internal.ws.model.RuntimeModelerException: runtime modeler error
还有就是如果jdk版本在1.6下,也会出现上面的异常。
解决办法有:
1> 先用apt命令将主程序进行编译,然后生成一些java文件
2> 升级JDK到版本jdk1.6u17或以后
2、 发布HelloWorldService,代码如下:
package com.hoo.service.deploy; import javax.xml.ws.Endpoint; import com.hoo.service.HelloWorldService; /** * <b>function:</b> 发布CXF WebService * @author hoojo * @createDate 2011-3-17 上午09:24:33 * @file DeployHelloWorldService.java * @package com.hoo.deploy * @project CXFWebService * @blog http://blog.csdn.net/IBM_hoojo * @email [email protected] * @version 1.0 */ public class DeployHelloWorldService { /** * <b>function:</b>发布WebService * @author hoojo */ public static void deployService() { System.out.println("Server start ……"); HelloWorldService service = new HelloWorldService(); String address = "http://localhost:9000/helloWorld"; Endpoint.publish(address, service); } public static void main(String[] args) throws InterruptedException { //发布WebService deployService(); System.out.println("server ready ……"); Thread.sleep(1000 * 60); System.out.println("server exiting"); //休眠60秒后就退出 System.exit(0); } }
运行上面的main函数后,如果没有发现异常。基本信息是这样的:
Server start …… 2011-3-17 10:17:25 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass 信息: Creating Service {http://service.hoo.com/}HelloWorldServiceService from class com.hoo.service.HelloWorldService 2011-3-17 10:17:25 org.apache.cxf.endpoint.ServerImpl initDestination 信息: Setting the server's publish address to be http://localhost:9000/helloWorld 2011-03-17 10:17:25.375:INFO::jetty-7.2.2.v20101205 2011-03-17 10:17:25.468:INFO::Started SelectChannelConnector@localhost:9000 server ready ……
那么你在WebBrowser中请求:
http://localhost:9000/helloWorld?wsdl就可以看到xml内容了。
3、 定制客户端调用WebService的接口,这个接口中的方法签名和参数信息可以从wsdl中的内容看到,代码如下:
package com.hoo.service;
import javax.jws.WebParam;
import javax.jws.WebService;
/**
* <b>function:</b> 客户端调用WebService所需要的接口
* @author hoojo
* @createDate 2011-3-17 上午09:00:00
* @file IHelloWorldService.java
* @package com.hoo.service
* @project CXFWebService
* @blog http://blog.csdn.net/IBM_hoojo
* @email [email protected]
* @version 1.0
*/
@WebService
public interface IHelloWorldService {
public String sayHello(@WebParam(name = "name") String name);
}
4、 编写客户端调用WebService代码
package com.hoo.client;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.hoo.service.IHelloWorldService;
/**
* <b>function:</b>CXF WebService客户端调用代码
* @author hoojo
* @createDate 2011-3-16 上午09:03:49
* @file HelloWorldServiceClient.java
* @package com.hoo.client
* @project CXFWebService
* @blog http://blog.csdn.net/IBM_hoojo
* @email [email protected]
* @version 1.0
*/
public class HelloWorldServiceClient {
public static void main(String[] args) {
//调用WebService
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(IHelloWorldService.class);
factory.setAddress("http://localhost:9000/helloWorld");
IHelloWorldService service = (IHelloWorldService) factory.create();
System.out.println("[result]" + service.sayHello("hoojo"));
}
}
运行上面的程序后,结果如下:
2011-3-17 10:23:34 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
信息: Creating Service {http://service.hoo.com/}IHelloWorldServiceService from class com.hoo.service.IHelloWorldService
[result]hoojo say: Hello World
