java - Axis 故障: "Service class must have public as access Modifier"

Question

我正在尝试构建一个简单的 Web 服务。我关注this tutorial而且效果很好。

但是当我更改为 Converter 类创建接口(interface)时，Eclipse 自动包含 IConverter.class 和 Converter.class 但当我运行测试时，它总是返回以下结果:

<soapenv:Reason>
    <soapenv:Text xml:lang="en-US">
        Service class wtp.IConverter must have public as access Modifier
    </soapenv:Text>
</soapenv:Reason>

我在 iConverter 及其方法的代码中有 public 关键字。

这是我的java源代码:

界面:

package wtp;
public interface IConverter {
    public float celToF(float cel);
    public float fToCel(float f);
}

实现:

package wtp;

public class Converter implements IConverter {

    @Override
    public float celToF(float cel) {
        return cel * 9 / 5 + 32;
    }

    @Override
    public float fToCel(float f) {
        return (f - 32) * 5 / 9;
    }
}

服务.xml:

<service name="IConverter">
    <Description>
        Test ws
    </Description>
    <messageReceivers>
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only" class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out" class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
    </messageReceivers>
    <parameter name="ServiceClass" locked="false">wtp.IConverter
    </parameter>
</service>

    </servlet-mapping>
</web-app>

如何解决这个问题？

不要将接口(interface)名称作为服务类传递——传递实现该接口(interface)的类的名称。 Axis2 正在尝试使用反射创建服务类的实例。 services.xml中的参数定义应如下:

<parameter name="ServiceClass" locked="false"> wtp.Converter </parameter>
