在学习Web Service的时候，从网上找到前辈的博客http://www.cnblogs.com/hexinlin/p/3358558.html，并依此文的方法按部就班：编写欲发布的java类HelloDemo.java -> 生成.arr文件并发布服务至Tomcat\webapps\axis2\WEB-INF\services\下，且访问http://127.0.0.1:8080/axis2/services/HelloDemo?wsdl成功…但当行至文中步骤“c.生成stub类”，在Axis Codgen wizard向导WSDL file location一栏中填入“http://127.0.0.1:8080/axis2/services/HelloDemo?wsdl”时，报错：“Specified WSDL is invalid!, Please select a validated *.wsdl/*.xml file on previous page.”
package com.hxl.webservice.service;
public class HelloDemo {
public String sayHello(String name) {
return "Hello"+name;
}
public String getResp() {
return "请求被响应";
}
}
一时没找到解决办法，只能另辟蹊径：用原先的HelloDemo.java生成一个WSDL文件HelloDemo.wsdl存在本地——D:\Project\TestWebSer\src\HelloDemo.wsdl。
然后利用HelloDemo.wsdl文件再生成相关的java代码。如下：
ExtensionMapper.java
GetResp.java
GetRespResponse.java
HelloDemoCallbackHandler.java
HelloDemoStub.java
SayHello.java
SayHelloResponse.java
TestMethods.java
在HelloDemoStub.java中“implements HelloDemo”处报错。这是由于HelloDemo.java中的HelloDemo类并非接口interface。只需将“implements HelloDemo”删除即可。
public class HelloDemoStub extends org.apache.axis2.client.Stub
implements HelloDemo{
protected org.apache.axis2.description.AxisOperation[] _operations;
然后要做的是实现HelloDemoCallbackHandler中的receiveResultgetResp和receiveResultsayHello方法，以此来得到你想要的东西：
package com.hxl.webservice.stub;
import com.hxl.webservice.service.HelloDemoCallbackHandler;
import com.hxl.webservice.service.SayHelloResponse;
import com.hxl.webservice.service.GetRespResponse;
public class MyCallBack extends HelloDemoCallbackHandler {
@Override
public void receiveResultgetResp(GetRespResponse result) {
System.out.println(result.getLocal_return());
}
@Override
public void receiveResultsayHello(SayHelloResponse result) {
System.out.println(result.getLocal_return());
}
}
然后再写一个方法集中调用的类
TestMethods
：
package com.hxl.webservice.service;
import com.hxl.webservice.stub.*;
import java.rmi.RemoteException;
import org.apache.axis2.AxisFault;
public class TestMethods {
public void testGetResp() throws Exception{
HelloDemoStub stub = new HelloDemoStub();
GetResp gr = new GetResp();
System.out.println(stub.getResp(gr).get_return());
}
public void testSayHello() throws Exception{
HelloDemoStub stub = new HelloDemoStub();
SayHello sh = new SayHello();
sh.setName(" hxl");
System.out.println(stub.sayHello(sh).get_return());
}
public void testGetAyn() throws Exception {
HelloDemoStub stub = new HelloDemoStub();
GetResp gr = new GetResp();
stub.startgetResp(gr ,new MyCallBack());
SayHello sh = new SayHello();
sh.setName(" Darren!");
stub.startsayHello(sh, new MyCallBack());
System.out.println("异步调用");
System.in.read();
}
}
最后，写一个含main方法的测试类Clnt：
package com.hxl.webservice.service;
import java.rmi.RemoteException;
import org.apache.axis2.AxisFault;
public class Clnt {
/**
* @param args
* @throws Exception
*/
public static void main(String[] args) throws Exception {
TestMethods tm = new TestMethods();
//tm.testGetResp();
//tm.testSayHello();
tm.testGetAyn();
}
}
执行打印结果：
异步调用
请求被响应
Hello Darren!
