我正在尝试通过本地RESTful Web服务发送一些消息。允许URL包含查询参数。我的REST方法处理器没有看到那些查询参数。有谁看到我做错了什么？
我使用的是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"

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

-->
<bean id="steve" class="messagerouter.EmployeeInfo">

<argument value="D."/>
<argument value="Huston"/>
<argument value="1234"/>
</bean>
<bean id="crewMock" class="messagerouter.CrewServiceMock">

</entry>
</map>
</property>
</bean>

</camelContext>
</blueprint>
我设置请求的WebService类是：
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);
}
}
我的服务调用接口类是：
@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);
}
处理请求的类是：
@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();
}
}
当我运行它时，我在测试输出中看到以下内容：
ID：1 地址：http://localhost:9000/rest/authentication/rraa/employees/steve%3Fpin=1234&reason=INIT Http-Method：GET Content-Type：application / xml
{steve=messagerouter.EmployeeInfo@1dd62581} id是steve？pin = 1234＆amp; reason = INIT scac是rraa 原因是空的
因此，查询参数显然没有被解析出来 - 它们被附加到最后一个路径参数。我做错了吗？
答案 0 :(得分：2)
您的界面有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);
}
