Camel cxf REST 请求不分离查询参数

Question

我正在尝试通过本地 RESTful 网络服务发送一些消息。 URL 允许包含查询参数。我的 REST 方法处理器没有看到这些查询参数。有人看到我做错了什么吗？

我正在使用 Camel 2.16.0。

我的蓝图路线 XML 是：

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <bean id="packageWebServiceReplyForIss" class="com.rockwellcollins.railwaynet.messagerouter.routing.PackageWebServiceReplyForIss"/>

  <!-- These two cooperate to send web service requests to the mocked

            <entry key="steve" value-ref="steve"/>
          </map>
        </entry>
      </map>
    </property>
  </bean>
  <camel-cxf:rsClient id="webService" address="http://localhost:9000" serviceClass="com.rockwellcollins.railwaynet.messagerouter.routing.WebService" loggingFeatureEnabled="true"/>

  <camelContext id="rraaCamelContext" xmlns="http://camel.apache.org/schema/blueprint">
    <dataFormats>

      <json id="IssRequest" library="Jackson"/>
    </dataFormats>

    <!-- Mocked out web service -->
    <route id="CrewMock">
      <from uri="jetty:http://localhost:9000?matchOnUriPrefix=true"/>
      <to uri="cxfbean:crewMock"/>
    </route>

    <route id="rraaIss">
      <from uri="seda:from_rraa"/>
      <process ref="issPreprocessor"/>
      <unmarshal ref="IssRequest"/>
      <process ref="webServiceProcessor"/>
      <to uri="cxfrs:bean:webService"/>
      <process ref="packageWebServiceReplyForIss"/>
      <to uri="seda:to_rraa"/>
    </route>
  </camelContext>

</blueprint>

我的WebServiceclass设置请求是：

public class WebServiceProcessor implements Processor {

    @Override
    public void process(Exchange exchange) throws Exception {
        exchange.setPattern(ExchangePattern.InOut);
        Message in = exchange.getIn();
        // Using proxy client API; needs the op name.
        in.setHeader(CxfConstants.CAMEL_CXF_RS_USING_HTTP_API, Boolean.FALSE);
        in.setHeader(CxfConstants.OPERATION_NAME, "verifyEmployee");
        VerifyEmployeeRequest req = in.getBody(VerifyEmployeeRequest.class);
        MessageContentsList params = new MessageContentsList();
        params.add(req.getHeader().getScac());
        params.add(req.getBody().getEmployeeID());
        params.add(req.getBody().getPin());
        params.add(req.getBody().getReason());
        in.setBody(params);
    }
}

我的服务调用接口 class 是：

@Path(value="/rest")
public interface WebService {

    @GET
    @Path(value="/authentication/{scac}/employees/{id}?pin={pin}&reason={reason}")
    @Produces({ MediaType.APPLICATION_JSON })
    public String verifyEmployee(@PathParam("scac") String scac,
                                 @PathParam("id") String id,
                                 @PathParam("pin") String pin,
                                 @PathParam("reason") String reason);
}

处理请求的class是：

@Path("/rest")
public class CrewServiceMock {

    // scac -> { id -> employeeInfo }
    private Map<String, Map<String, EmployeeInfo> > info;

    public Map<String, Map<String, EmployeeInfo> > getInfo()
    { return info; }
    public void setInfo(Map<String, Map<String, EmployeeInfo> > info)
    { this.info = info; }

    @GET
    @Path("/authentication/{scac}/employees/{id}")
        public Response getAuth(@PathParam("scac") String scac,
                                @PathParam("id") String id,
                                @QueryParam("reason") String reason,
                                @QueryParam("pin") String pin) {
        Map<String, EmployeeInfo> employees = info.get(scac);
        if (employees == null) {
            return Response.status(404).build();
        }
        System.out.println(employees);
        System.out.println("id is " + id);
        System.out.println("scac is " + scac);
        System.out.println("reason is " + reason);
        EmployeeInfo emp = (EmployeeInfo)employees.get(id);
        if (emp == null) {
            return Response.status(404).entity("{ message: \"id not found\" }").build();
        }
        return Response.status(200).entity("{ \"employeeID\": " + id + ", \"employeeName\": { \"first\": \"" + emp.getFirstName() + "\", \"middle\": \"" + emp.getMiddleName() + "\", \"last\": \"" + emp.getLastName() + "\" } }").build();
    }
}

当我运行时，我在测试输出中看到以下内容：

[Camel (rraaCamelContext) 线程 #0 - seda://from_rraa] 信息 org.apache.cxf.interceptor.LoggingOutInterceptor - 出站消息

编号：1 地址：http://localhost:9000/rest/authentication/rraa/employees/steve%3Fpin=1234&reason=INIT Http-Method：获取 Content-Type: application/xml

Headers: {OriginalHeader=[{name=VerifyEmployeeRequest, version=1, scac=rraa, timeSent=null, uuid=abcd-1234}], Content-Type=[application/xml], 接受=[application/json]}

{史蒂夫=messagerouter.EmployeeInfo@1dd62581} id 是 steve?pin=1234&reason=INIT scac 是 rraa 原因为空

因此，查询参数显然没有被解析出来——它们附加到最后一个路径参数。我做错了什么吗？

Answer 1

您的接口有 4 个路径参数，而不是 2 个路径和 2 个查询参数，它应该是：

@Path(value="/rest")
public interface WebService {

    @GET
    @Path(value="/authentication/{scac}/employees/{id}")
    @Produces({ MediaType.APPLICATION_JSON })
    public String verifyEmployee(@PathParam("scac") String scac,
                             @PathParam("id") String id,
                             @QueryParam("pin") String pin,
                             @QueryParam("reason") String reason);
}
