java - 通过 Camel cxf 组件连接 SOAP 端点时，无法在 WrapperClassOutInterceptor 处转换为 java.lang.String 错误

Question

我正在实现一个调用 SOAP Web 服务并处理响应的实现。

我从下面的帖子开始，当它连接到 Web 服务端点时出现以下错误

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

错误:“com.cleverbuilder.bookservice.GetBook 无法在 WrapperClassOutInterceptor 处转换为 java.lang.String”。

这可能是什么原因？

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

喜欢在日志下面突出显示

• BodyType:com.cleverbuilder.bookservice.GetBook，

• 正文:

  <?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

我找到了一个使用 dataFormat=PAYLOAD 的选项，如下所述。无论如何，请开放更多选择。

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

例如:

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);
