error-handling - 没有这样的操作: HTTP GET PATH_INFO:/services/EchoUMO

Question

我从互联网上下载了回声样本。我有1个Java类

package org.mule.example.echo;

public class Echo
{
    public Echo()
    {
    }

    public String echo(String string)
    {
        return string;
    }
}

和一个xml文件

 <?xml version="1.0" encoding="UTF-8"?>
 <mule> 

 <flow name="EchoFlow">
        <inbound-endpoint address=":65082/services/EchoUMO" exchange-pattern="request-response"/>
        <cxf:jaxws-service serviceClass="org.mule.example.echo.Echo"/>
        <component>
            <singleton-object class="org.mule.example.echo.Echo" />
        </component>
    </flow>
</mule>

当我在浏览器中编写:65082/services/EchoUMO时，没有得到任何好的结果。在我的控制台中，我看到此错误:

 WARN  2013-03-04 12:08:10,713 [[sample-echo].connector.http.mule.default.receiver.02] org.apache.cxf.phase.PhaseInterceptorChain: Interceptor for {http://echo.example.mule.org/}EchoService has thrown exception, unwinding now

    at org.apache.cxf.transport.ChainInitiationObserver.onMessage(ChainInitiationObserver.java:123)

您能解释一下我的情况吗？

当我在浏览器中编写 :65082/services/EchoUMO时，浏览器将显示以下页面:

<soap:Envelope>
    <soap:Body><soap:Fault>
        <faultcode>soap:Server</faultcode>
        <faultstring>No such operation: (HTTP GET PATH_INFO: /services/EchoUMO)</faultstring>
    </soap:Fault></soap:Body>
</soap:Envelope>

Answer 1

您的类(class)没有使用JAX-WS批注，因此您会收到错误。

您有2个选择:

保留当前类并使用simple service，即<cxf:simple-service serviceClass="org.mule.example.echo.Echo"/>

按照说明here

向您的POJO添加JAX-WS批注
