【问题描述】：

我是 Apache Camel 的新手，我使用的是 Red Hat CodeReady Studio 12.16.0.GA。我想调用肥皂网络服务。这个例子我用过https://tomd.xyz/camel-consume-soap-service/

这是我的骆驼上下文文件

    <camelContext id="camel"
        xmlns="http://camel.apache.org/schema/spring" xmlns:order="http://fabric8.com/examples/order/v7">
        <route id="simple-route">
            <from id="_to2" uri="timer:timerName?delay=0&amp;repeatCount=1"/>
            <setBody id="_setBody2">
                <constant>"US"</constant>
            </setBody>
            <bean beanType="com.example.GetFullCountryInfoBuilder"
                id="_bean1" method="getFullCountryInfo"/>
            <setHeader headerName="operationNamespace" id="_setHeader1">
                <constant>http://www.oorsprong.org/websamples.countryinfo</constant>
            </setHeader>
            <setHeader headerName="operationName" id="_setHeader2">
                <constant>FullCountryInfo</constant>
            </setHeader>
            <to id="_to1" uri="cxf:bean:fullCountryInfoResponseClient"/>
            <bean beanType="com.example.GetFullCountryInfoBuilder"
                id="_bean2" method="getFullCountryInfoOutput"/>
            <log id="_log1" message=">>>${body}"/>
        </route>
    </camelContext>
</beans>

这是我的输入 bean

public class GetFullCountryInfoBuilder {
    
    public GetFullCountryInfoBuilder() {}
    @Bean
    public FullCountryInfo getFullCountryInfo(@Body String id) {
        FullCountryInfo request = new FullCountryInfo();
        request.setSCountryISOCode(id);
        return request;
    }
    @Bean
    public String getFullCountryInfoOutput(@Body FullCountryInfoResponse response) {
        String ret = response.getFullCountryInfoResult().getSName() + " - " + response.getFullCountryInfoResult().getSCapitalCity() + " - " + response.getFullCountryInfoResult().getSCurrencyISOCode();
        return ret;
    }
}

还是报错 org.apache.cxf.interceptor.Fault: org.oorsprong.websamples.FullCountryInfo cannot be cast to java.lang.String 看起来 CXF 不处理 FullCountryInfo 对象，但 String 和 Camel 尝试对其进行转换。
当我将 getFullCountryInfo 的返回更改为 String 时，此异常消失，但又出现了几个异常。

Caused by: org.apache.camel.InvalidPayloadException: No body available of type: org.oorsprong.websamples.FullCountryInfoResponse but has value: [org.oorsprong.websamples.TCountryInfo@3c5110df] of type: org.apache.cxf.message.MessageContentsList on: Message[].

【解决方案1】：

因此，CXF 的输入不是示例中描述的对象，而是字符串。 CXF 的输出是 org.apache.cxf.message.MessageContentsList，您必须将其转换为字符串以记录它。在这种情况下，我使用了 getFullCountryInfoOutput bean。
