运用xfire做个简单的webservice _Web前端

使用xfire做个简单的webservice

闲话不说，直接上。（对于xfire的介绍等的东西，见百度或谷歌）

1、下载xfire。地址： http://xfire.codehaus.org/Download ?

????? xfire-distribution-1.2.6.zip
????? xfire-all-1.2.6.jar

2、新建j2ee项目。导入jar包

????

3、在web.xml中配置xfire的servlet

        <servlet>
		<servlet-name>XFireServlet</servlet-name>
		<servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>XFireServlet</servlet-name>
		<url-pattern>/servlet/XFireServlet/*</url-pattern>
	</servlet-mapping>
	<servlet-mapping>
		<servlet-name>XFireServlet</servlet-name>
		<url-pattern>/services/*</url-pattern>
	</servlet-mapping>

4、创建webservice服务接口和实现类

HelloWorld.java

public interface HelloWorld {

	public String sayHello();
}

HelloWorldImpl.java

public class HelloWorldImpl implements HelloWorld {
	@Override
	public String sayHello() {
		// TODO Auto-generated method stub
		System.out.println("Hello,all----------I'm in server.");
		return "Hello,all----------I'm in client.";
	}

}

5、配置xfire的文件。需要在META-INF下新建文件夹xfire，在xfire文件夹下创建services.xml文件

? ? ?

services.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xfire.codehaus.org/config/1.0">

<service>
	<name>HelloService</name>
	<namespace>http://localhost:8080/myxfire</namespace>
	<serviceClass>com.HelloWorld</serviceClass>
	<implementationClass>com.HelloWorldImpl</implementationClass>
</service>
</beans>

6、启动taomcat。使用浏览器打开http://localhost:8080/myxfire/services/

????

??? 如果这一步报错：

??? class path resource [META-INF/xfire/services.xml] cannot be opened because it does not exist

??? 则需要将META-INF文件夹拷到WEB-INF文件夹下，如下图：

???

7、调用webservice

public static void main(String[] args) {
		String url = "http://localhost:8080/myxfire/services/HelloService?wsdl";
		try {
			Client client = new Client(new URL(url));
			Object [] obj = client.invoke("sayHello",new Object[]{});
			System.out.println(obj[0]);
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}
