通过Camel cxf组件连接SOAPendpoint时，无法强制转换为WrapperClassOutInterceptor上的java.lang.字符串错误

Question

我正在实现调用SOAP Web服务并处理响应。

我从下面的帖子开始，当它连接到web服务endpoint时，我遇到了下面的错误

• https://tomd.xyz/articles/camel-soap-service/

错误：“com.cleverbuilder.bookservice.GetBook无法转换为java.lang.String”，位于WrapperClassOutInterceptor。

这可能是什么原因？

请注意http://localhost:8423/test/BookService已经启动，工作正常。我在SOAP路由器外面进行了测试，它在那里工作得很好。

喜欢在下面的日志中突出显示

<?xml
   version="1.0" encoding="UTF-8" standalone="yes"?><ns2:GetBook
   xmlns:ns2="http://www.cleverbuilder.com/BookService/">   
   <ID>12345</ID></ns2:GetBook>,

输出：空

我想出了一个选项与dataFormat=PAYLOAD如下所述。无论如何，打开更多选项。

对于SoapJaxbDataFormat，需要导入camel-soap依赖项。

如：

String WS_URI = "cxf://http://myserver/customerservice?serviceClass=com.example.customerservice&dataFormat=MESSAGE";
SoapJaxbDataFormat soapDF = new SoapJaxbDataFormat("com.example.customerservice", new ServiceInterfaceStrategy(CustomerService.class));
from("direct:customerServiceClient")
  .onException(Exception.class)
    .handled(true)
    .unmarshal(soapDF)
  .end()
  .marshal(soapDF)
  .to(WS_URI)
  .unmarshal(soapDF);
