Instead think of separating each of those state checks in separate controllers each referenced by a single URI. For every "if else" you may need another resource. In this way the URI act as a type of router, automatically routing the resource you are changing to the right controller.
A direct side effect of this is easier to understand code, greater decoupling, and in my opinion less bugs created by trying to wrap your minds around all those if statements.
This video is a very good treatment on resource oriented design and Rest.

In that case, the handler looks up an unmarshaller keyed by the content type of the body, uses the unmarshaller to turn the bitstream of the body into a running object, tells the object to act. and the object does whatever it does.
E.g.
Unmarshaller unmarshaller = unmarshallers.lookUp(request.contentType);
PostAction action = unmarshaller.unmarshall(request.body);
action.performUpon(theActualResource);
