java - AXIS2 客户端返回带有空值而不是属性的对象

Question

我有这样的结构，我需要通过webService返回

public class StructureClass implements Serializable
{

    public StructureClass()
    {
        exampleFIO = new FIO();
    }
    public FIO exampleFIO;
    public String result;
}

public class FIO implements Serializable{

    public String FirstName;
    public String LastName;

}

Web服务应用程序:

public class ReturnObject {
    public StructureClass retObject()
    {
        StructureClass structClassObject = new StructureClass();
        structClassObject.exampleFIO.FirstName = "A";
        structClassObject.exampleFIO.LastName = "G";
        structClassObject.result = "good";
        return structClassObject;
    }
}

我在 AXIS2 和 Eclipse 的帮助下构建了 Web 服务应用程序

WSDL 是:

当我尝试在客户的帮助下调用它时

RPCServiceClient serviceClient = new RPCServiceClient();
            Options options = serviceClient.getOptions();

            EndpointReference targetEPR = new EndpointReference(
                    "http://localhost:8080/XXXXXX/services/ReturnObject");
            options.setTo(targetEPR);

            options.setAction("sendAttachment");

            QName opGetObject = new QName("http://objectreturn.xxxxxx.com", "retObject");
            Object[] opSetArgs = new Object[] { };
            Class[] returnTypes = new Class[] { StructureClass.class };

            Object[] returnArray = serviceClient.invokeBlocking(opGetObject,
                    opSetArgs, returnTypes);


        StructureClass xx = (StructureClass)returnArray[0];

        System.out.println(xx.result);

对于xx类的所有属性，我得到null

您能帮忙解决一下这里可能出现的问题吗？

谢谢，安德鲁

检查Axis2 Apache Tutorial并按照教程编写代码。

(例如，从类中删除实现 Serialized，除非您确实需要它，否则在类中创建 getter 和 setters 方法)
