webservice 开发 axis2 简略部署服务

axis2-1.4.1 下的
axis2.war 放到tomcat下

简单编写一个服务，供给系统外部调用

import java.util.Random;



public class SimpleService {

	public String getGreeting(String name) {
		return "你好 "+name;
	}
	
	public int getPrice() {
		return new Random().nextInt(1000);
	}
}

?

SimpleService.class 放到 WEB-INF/pojo? 下
就这么简单 就构成了一个服务

客户端(Java)：

package client;

import java.rmi.RemoteException;
import java.util.Iterator;

import javax.xml.namespace.QName;

import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;

import org.apache.axis2.AxisFault;
import org.apache.axis2.Constants;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;
import org.apache.axis2.rpc.client.RPCServiceClient;

public class RPCClient {

	public static void main(String[] args) throws RemoteException {

		//RPC 方式调用 服务端
		//runRPC();
		
		//Axiom 方式调用 服务端
		//runAxiom();
		
		//wsdl2java.bat -uri http://localhost:8080/axis2/services/SimpleService?wsdl -p client -s -o stub
		//工具自动生成
		SimpleServiceStub stub = new SimpleServiceStub();
		SimpleServiceStub.GetGreeting gg = new SimpleServiceStub.GetGreeting();
		gg.setName("超人");
		System.out.println(stub.getGreeting(gg).get_return());
		System.out.println(stub.getPrice().get_return());
	}

        //2或者用下面遍历的方式获取访问结果  
        Iterator<OMElement> it=result.getChildElements();  
        while(it.hasNext()){  
            OMElement ome=(OMElement)it.next();  
            if(ome!=null){  
                String omevalue=ome.getText();  
                if (omevalue != null) {  
                    System.out.println("2:axiom客户端方式访问结果:"+omevalue);  
                }  
            }  
              
        }  
          
        //3使用QName参数  
        QName qname = new QName("http://device.axis2.hd.org",  
                "getGreeting");  
        result.getFirstChildWithName(qname);  
        System.out.println("3:axiom客户端方式QName访问结果第一个element:"+result.getFirstElement().getText());  
		
	}
}

结果：
