MYECLIPSE 开发Web Service之详细讲解--第二节

Posted 2021-05-17 tropica

 第一节中说明了怎么开发webservice，这节主要描述怎么测验和应该注意的内容

一：开发JAVA客户端

上面一节说了，如果你发现下面的内容，那就是发布成功了；

And now... Some Services

• CallSoapImpl (wsdl)
  • example
• AdminService (wsdl)
  • AdminService
• Version (wsdl)
  • getVersion

CallSoapImpl (wsdl) 这个就是新增加的节点，点wsdl链接，出现XML相关的文件，然后您要做的是点右键，查看源代码。讲内容保存下来，命名CallSoapImpl.wsdl（名称是随便的），这个文件就是我们下面生成客户端需要的。

生成客户端
java org.apache.axis.wsdl.WSDL2Java -p com.xuzr  CallSoapImpl.wsdl

看到了吧，上面就是执行客户端的脚本，com.xuzr  是生成的文件包

然后你到执行脚本的目录下看，会发现多了文件夹，细点，发现，会出现JAVA文件，分别为：

CallSoap.java 

CallSoapImpl_PortType.java

CallSoapImplSoapBindingStub.java

CallSoapLocator.java

注意看CallSoapLocator.java文件，会发现里面有相应的servlet地址，

 public java.util.Iterator getPorts() {
        if (ports == null) {
            ports = new java.util.HashSet();
            //ports.add(new javax.xml.namespace.QName("http://localhost:7001/CallSmsService/services/CallSoapImpl", "CallSoapImpl"));
            ports.add(new javax.xml.namespace.QName("http://10.168.6.68:8383/CallSmsService/services/CallSoapImpl", "CallSoapImpl"));
           
        }

呵呵，这就是我们客户端需要用到的。

二：调用web service

上面的步骤都完成的情况下，那么就需要我们来调用咯，呵呵，其实客户端代码有很多种，比如

        org.codehaus.xfire.service.Service srvcModel = new ObjectServiceFactory().create(CallSoap.class);
        XFireProxyFactory factory =
        new XFireProxyFactory(XFireFactory.newInstance().getXFire());
//     String helloWorldURL =
//        "http://localhost:7001/HelloWorld/services/HelloWorldService";
        String helloWorldURL =
         "http://localhost:7001/CallSoap/services/CallSoapImpl";
     try {
      CallSoap srvc = (CallSoap)factory.create(srvcModel, helloWorldURL);
        String result = srvc.getCallSoapImpl().example(" 中文测验hello world..11");
        System.out.print(result);
     } catch (MalformedURLException e){
           e.printStackTrace();
     }
 }

但是我们为了让初学的人更容易理解，我建议大家用下面的测验代码：

    CallSoap service = new CallSoapLocator();
  try {
      System.out.println(service.getCallSoapImpl().example(bufferdemo.toString()));
   
   
  } catch (ServiceException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

哈哈，简单吧，如果成功，会出现下面的情况，当然，我的调用很简单，就是返回OK，所以就不需要写了，在调用的过程中有N多日志，你不要管，那都是正常的。

好了，关于用Myeclipse开发WEB Service的就讲到这里咯，我相信大家应该很容易上手的，毕竟需要我们写的代码真的不多，恩，下一节我讲下一个开发Demo，EJB的开发和调试，大家等着吧，欢迎和我交流：[e-mail]
