Spring-WS 端点文档文字 wrapping/unwrapping

Question

我正在与一个期望我们使用 WS-I 1.1 document/literal 包装消息的系统集成。我们有一个有效的解决方案，但似乎有更简单的方法来处理有效负载 wrapping/unwrapping.

我有一个端点如下：

@Endpoint
public class FooEndpoint
{

  @Autowired
  private FooService FooService;

  @PayloadRoot(localPart = "Foo", namespace = "http://foo/service")
  @ResponsePayload
  public JAXBElement<FooAcknowledgementType> Foo(
        @RequestPayload JAXBElement<FooRequestType> requestElement)
  {
    FooRequestType request = requestElement.getValue();
    FooAcknowledgementType response = FooService.Foo(request);

    // TODO: Find a better solution with the wrapped response
    return new JAXBElement<FooAcknowledgementType>(new QName(
          "http://foo/service", "FooAcknowledgement"),
          FooAcknowledgementType.class, null, response);
  }
}

定义合同的 WSDL 如下：

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:tns="http://foo/service" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
  xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns="http://www.w3.org/2000/09/xmldsig#" xmlns:ns1="http://foo/schema"
  name="Foo" targetNamespace="http://foo/service">
  <wsdl:types>
    <xsd:schema xmlns:s="http://foo/schema" targetNamespace="http://foo/service">
      <xsd:import namespace="http://foo/schema" schemaLocation="foo_types.xsd" />
      <xsd:element name="Foo" type="s:FooRequestType" />
      <xsd:element name="FooAcknowledgement" type="s:FooAcknowledgementType" />
    </xsd:schema>
  </wsdl:types>
  <wsdl:message name="FooRequest">
    <wsdl:part name="parameter" element="tns:Foo" />
  </wsdl:message>
  <wsdl:message name="FooAcknowledgement">
    <wsdl:part name="parameter" element="tns:FooAcknowledgement" />
  </wsdl:message>
  <wsdl:portType name="FooPortType">
    <wsdl:operation name="Foo">
      <wsdl:input message="tns:FooRequest" />
      <wsdl:output message="tns:FooAcknowledgement" />
    </wsdl:operation>
  </wsdl:portType>

  <wsdl:binding name="FooBinding" type="tns:FooPortType">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http" />
    <wsdl:operation name="Foo">
      <soap:operation soapAction="http://foo/serviceFoo" />
      <wsdl:input>
        <soap:body use="literal" />
      </wsdl:input>
      <wsdl:output>
        <soap:body use="literal" />
      </wsdl:output>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:service name="Foo">
    <wsdl:documentation>Foo web service</wsdl:documentation>
    <wsdl:port name="FooService" binding="tns:FooBinding">
      <soap:address location="http://localhost:8080/foo/services/Foo" />
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

我已经从上面端点 class 中引用的 foo_types.xsd 模式生成了 jaxb 对象。

问题是，当我们收到 document/literal 包装样式的 soap 消息时，soap 主体负载看起来像

<x:Foo>
  <!-- elements from s:FooRequestType -->
</x:Foo>

并且我们需要像

这样的 soap body payload 来响应

<x:FooAcknowledgement>
  <!-- elements from s:FooAcknowledgementType -->
</x:FooAcknowledgement>

Spring-WS 是否可以开箱即用？我们可以按原样使用代码使用和生成兼容的消息，但看起来这可能不是正确的方法，因为 http://docs.spring.io/spring-ws/site/reference/html/tutorial.html#tutorial.xsd[= 的 spring 文档中未引用这种样式17=]

Answer 1

我们的解决方案是通过我们的 jaxb bindings.xml，将命名空间和元素名称添加到 @XmlRootElement 注释中，例如

<jaxb:bindings node="xs:complexType[@name='fooType']">
  <annox:annotate target="class">
    <annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="FooAcknowledgement" namespace="http://foo/service"/>
  </annox:annotate>
</jaxb:bindings>
