有很多关于 Apache Camel + CXF-Endpoint 和 RPC/encoded legacy webservices 的信息。但是直到现在我还没有找到解决问题的方法。
我想通过 CXF 端点从 Apache Camel 调用 RPC/编码的 Web 服务。CXF 不支持 RPC/编码的 Web 服务。所以我尝试了两种方法来解决这个问题。
将 wsdl 从 RPC/encoded 转换为 RPC/literal 并生成源文件。以 CXF 支持的 RPC/literal 样式调用 Web 服务。以下文章建议这种方法可以解决我的问题:使用 RPC/编码 Web 服务的最佳方式?
发送完整的 SOAP 消息而不映射到对象(无 JAXB)。
方法 1 和方法 2 都不起作用。在接下来的部分中,我将更详细地解释我的方法和问题。
先决条件
- 阿帕奇雄猫 7
- 阿帕奇骆驼 2.14.1
- 阿帕奇 CXF 2.7.10
- Webservice Endpoint 在http://localhost:9000/myfunctionalmock上使用 SOAP-UI 5.0.0 进行模拟
第一种方法:将 wsdl RPC/encoded 转换为 RPC/literal 并生成源
在 RCP/encoded wsdl 中,我进行了以下更改:
WSDL 绑定:
<wsdl:binding name="exampleSoapBinding" type="impl:MyFunctionalWebservices">
<wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="isAlive">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="isAliveRequest">
<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://my.example.com/myFunction" use="encoded"/>
</wsdl:input>
...
至
<wsdl:binding name="exampleSoapBinding" type="impl:MyFunctionalWebservices">
<wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="isAlive">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="isAliveRequest">
<wsdlsoap:body namespace="http://my.example.com/myFunction" use="literal"/>
</wsdl:input>
…
对象数组:
<complexType name="ArrayOfMyElement">
<complexContent>
<restriction base="soapenc:Array">
<attribute ref="soapenc:arrayType" wsdl:arrayType="impl:MyElement[]"/>
</restriction>
</complexContent>
</complexType>
至
<complexType name="ArrayOfMyElement">
<xsd:sequence>
<xsd:element name="MyElement"
type="impl:MyElement"
minOccurs="0"
maxOccurs="unbounded"/>
</xsd:sequence>
</complexType>
简单类型的数组:
<complexType name="ArrayOf_xsd_string">
<complexContent>
<restriction base="soapenc:Array">
<attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:string[]"/>
</restriction>
</complexContent>
</complexType>
至
<complexType name="ArrayOf_xsd_string">
<xsd:sequence>
<xsd:element name="item"
type="xsd:string"
minOccurs="0"
maxOccurs="unbounded"/>
</xsd:sequence>
</complexType>
未定义类型(anyType)的数组:
<complexType name="ArrayOf_xsd_anyType">
<complexContent>
<restriction base="soapenc:Array">
<attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:anyType[]"/>
</restriction>
</complexContent>
</complexType>
至
<complexType name="ArrayOf_xsd_anyType">
<xsd:sequence>
<xsd:element name="item"
type="xsd:anyType" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
</complexType>
之后,我使用 IntelliJ Webservice 插件(通过 CXF wsdl2java)生成了源文件
在 Camel 中,我配置了以下端点:
CxfEndpoint endpoint = new CxfEndpoint();
endpoint.setAddress("http://127.0.0.1:9000/myfunctionalmock");
endpoint.setWsdlURL("wsdl/myservice_literal.wsdl");
endpoint.setServiceClass("com.my.example.MyFunctionalWebservices");
endpoint.setEndpointNameString("{http://my.example.com/myFunction}rpcrouter");
endpoint.setServiceNameString("{http://my.example.com/myFunction}MyFunctionalWebservicesService");
endpoint.setDataFormat(DataFormat.POJO);
endpoint.setSynchronous(true);
endpoint.setCamelContext(camelContext);
endpoint.setEndpointUriIfNotSpecified(MY_ENDPOINT_URL);
camelContext.addEndpoint(MY_ENDPOINT_URL, endpoint);
Camel路由中CXF-Endpoint的使用:
我想调用webservice的以下功能:
public Result isAlive(java.lang.String identifier);
骆驼路由中的计时器仅用于触发Web服务。
from("timer://myTimer?period=10000")
.log(LoggingLevel.INFO, "START Timer Webservice.")
.setBody().constant("1620000018")
.setHeader("operationName", constant("isAlive"))
.setHeader("operationNamespace", constant("http://my.example.com/myFunction"))
.to(MyCamelConfiguration.MY_ENDPOINT_URL);
这种方法的问题:
在运行时,部署时会出现以下消息:
2015-03-05 09:57:46,659; 2010; [localhost-startStop-1]; DEBUG; wsdl11.WSDLServiceBuilder; Operation {http://my.example.com/myFunction}isAlive cannot be unwrapped, input message must reference global element declaration with same localname as operation
运行时发生以下异常:
org.apache.cxf.binding.soap.SoapFault: No namespace on "HTML" element. You must send a SOAP request.

第二种方法:发送 SOAP 消息而不映射到对象。
Camel中的端点定义:
CxfEndpoint endpoint = new CxfEndpoint();
endpoint.setAddress("http://127.0.0.1:9000/myfunctionalmock");
endpoint.setEndpointNameString("{http://my.example.com/myFunction}rpcrouter");
endpoint.setServiceNameString("{http://my.example.com/myFunction}MyFunctionalWebservicesService");
endpoint.setDataFormat(DataFormat.RAW);
endpoint.setWrappedStyle(false);
endpoint.setSynchronous(true);
endpoint.setCamelContext(camelContext);
endpoint.setEndpointUriIfNotSpecified(MY_TEMPLATE_ENDPOINT_URL);
camelContext.addEndpoint(MY_TEMPLATE_ENDPOINT_URL, endpoint);
路线使用:
from("timer://myTimer?period=10000")
.log(LoggingLevel.INFO, "START Timer Webservice.")
.setBody().constant(
"<soapenv:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:myns=\"http://my.example.com/myFunction\">\n" +
" <soapenv:Header/>\n" +
" <soapenv:Body>\n" +
" <myns:isAlive soapenv:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">\n" +
" <identifier xsi:type=\"xsd:string\">1620000018</identifier>\n" +
" </myns:isAlive>\n" +
" </soapenv:Body>\n" +
"</soapenv:Envelope>"
)
.to(MyCamelConfiguration.MY_TEMPLATE_ENDPOINT_URL)
.log(LoggingLevel.INFO, "END Timer Webservice.")
.log(LoggingLevel.INFO, "Body after ws call = ${body}");
但是http://localhost:9000/myfunctionalmock上的网络服务永远不会被调用。我在日志文件中发现了以下日志消息:
2015-03-05 10:56:35,522; 12843; [Camel (camel-1) thread #0 - timer://myTimer]; DEBUG; phase.PhaseInterceptorChain; Invoking handleMessage on interceptor org.apache.cxf.jaxb.attachment.JAXBAttachmentSchemaValidationHack@1d3694a

2015-03-05 10:56:35,523; 12844; [Camel (camel-1) thread #0 - timer://myTimer]; INFO ; helpers.MarkerIgnoringBase; END Timer Webservice.

<HEAD><TITLE>Redirection</TITLE></HEAD>
<BODY><H1>Redirect</H1></BODY>
两种方法都不起作用。是否有可能在 Camel 中通过 CXF 调用 RPC/编码的 Web 服务?
提前致谢。
