Question

我想让netty频道在@DELETE函数中执行某些操作：

@DELETE

@Path（ “/文件/ {路径}”）

@Produces（ “应用程序/ JSON;字符集= UTF-8”）

public Response deleteFile（

@PathParam("path") String path,

@QueryParam(value = "access") String access,

@Context HttpResponse httpResponse)

{

//i want to get the netty channel to do something.

}

但无法得到。我看到了RestEasy的资源代码：

public Object invoke（HttpRequest request，HttpResponse httpResponse，Object resource）抛出Failure，ApplicationException

{

  Object[] args = injectArguments(request, httpResponse);

  GeneralValidator validator = GeneralValidator.class.cast(request.getAttribute(GeneralValidator.class.getName()));
  if (validator != null)
  {
     validator.validateAllParameters(request, resource, method.getMethod(), args);
  }

  Method invokedMethod = method.getMethod();
  if (!invokedMethod.getDeclaringClass().isAssignableFrom(resource.getClass()))
  {
     // invokedMethod is for when the target object might be a proxy and
     // resteasy is getting the bean class to introspect.
     // In other words ResourceMethod.getMethod() does not have the same declared class as the proxy:
     // An example is a proxied Spring bean that is a resource
     // interface ProxiedInterface { String get(); }
     // @Path("resource") class MyResource implements ProxiedInterface {
     //     @GET String get() {...}
     // }
     //
     invokedMethod = interfaceBasedMethod;
  }

  Object result = null;
  try
  {
     result = invokedMethod.invoke(resource, args);
  }
  catch (IllegalAccessException e)
  {
     throw new InternalServerErrorException("Not allowed to reflect on method: " + method.toString(), e);
  }

HttpResponse httpResponse的args是一个NettyHttpResponse对象，所以我可以通过它得到频道。
那么我怎样才能获得频道？

您无法获取Netty频道，因为它是一个实施细节

RestEasy如何获得Netty频道？
