Java CFX Webservice and Delphi 2010



我正在努力遇到一些问题,请致电我的Java Web服务。只要我使用原始数据类型,例如字符串,整数等。一切正常。

但是,当我尝试将对象用作参数时,我的Java方法只会收到null。因此,映射似乎不起作用。我举了一个简单的例子:

Web服务的Java接口

@WebService(name="TestService", targetNamespace=CNAPBackOffice.NAMESPACE_SERVICES)
@SOAPBinding(style=SOAPBinding.Style.RPC, use=SOAPBinding.Use.LITERAL)
public interface TestService {
    @WebMethod(operationName="sendComplexType")
    @WebResult(name="okString")
    public String sendComplexType(TestData data);
}

Java实施

@WebService(endpointInterface = "lu.ciss.backoffice.cnap.services.TestService",
        portName = "TestEndpoint", serviceName = "TestService",
        targetNamespace = CNAPBackOffice.NAMESPACE_SERVICES)
public class TestServiceImpl implements TestService {
    @Override
    public String sendComplexType(TestData data) {
        return data.getTestString();
    }
}

testdata类

public class TestData {
    String testString;
    ... + Setter/Getter for testString
}

我使用生成的WSDL使用"组件 ->导入WSDL ..."菜单将其导入Delphi。之后,我像这样致电网络服务:

procedure TFRM_Test.TestClick(Sender: TObject);
var
Service: TestService;
data: TestData;
result: String;
begin
  Service := GetTestService(true);
  data := TestData.Create;
  data.testString := 'Bla';
  result := Service.sendComplexType(data);
  ShowMessage(result);
end;

就像我之前说过的,Java侧收到的无效,在这种情况下导致例外。因此,显然,两个世界之间的映射无法正常工作。我试图在WSDL导入菜单中更改不同的选项,但似乎无效。我看了Delphi发出的肥皂请求:

<?xml version="1.0"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
    <SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:NS2="http://cnap.backoffice.ciss.lu/services">
        <NS1:sendComplexType xmlns:NS1="http://cnap.backoffice.ciss.lu/services">
            <arg0 href="#1"/>
        </NS1:sendComplexType>
        <NS2:testData id="1" xsi:type="NS2:testData">
            <testString xsi:type="xsd:string">Bla</testString>
        </NS2:testData>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我从未在这个奇怪的参考概念之前见过。这会造成麻烦吗?或其他人有另一个想法,甚至更好:解决方案:)

预先感谢。

P.S。这是生成的WSDL:

</wsdl:definitions>

这是Delphi的错。

您的JSR-181/JSR-224注释的接口具有明确的@SOAPBinding(style=SOAPBinding.Style.RPC, use=SOAPBinding.Use.LITERAL),并且您生成的WSDL状态清楚地表明它是RPC/LITERAL WEBSERVICE

  <wsdl:binding name="TestServiceSoapBinding" type="tns:TestService">
    <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"></soap:binding>
    <wsdl:operation name="sendComplexType">
      <soap:operation soapAction="" style="rpc"></soap:operation>
      <wsdl:input name="sendComplexType">
        <soap:body namespace="http://cnap.backoffice.ciss.lu/services" use="literal"></soap:body>
      </wsdl:input>

delphi然而,使用MultireF值创建了SOAP编码的SOAP 1.1信封,并使用SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"表示。

因此,您必须在Delphi中调整一些选择...

也许Delphi无法导入RPC/字面意思?尝试切换到文档/文字/包装:

@SOAPBinding(style=SOAPBinding.Style.DOCUMENT, use=SOAPBinding.Use.LITERAL, parameterStyle = ParameterStyle.WRAPPED)
