Combining handler and router

We have written two different classes for the handler and router; however, we can declare the configuration that covers the functionality of both the router and handler in a single class. This can be done by combining the handler and router method pair in one single method as follows:

@Configurationpublic class StudentRouterHandlerCombined {  @Autowired  private StudentMongoRepository studentMongoRepository;    @Bean  RouterFunction<ServerResponse> returnStudentWithCombineFun(){            HandlerFunction<ServerResponse> studentHandler =                 serverRequest -> {                 int rollNo = getInt(serverRequest.pathVariable("rollNo"));                 return ServerResponse.ok().                    body(studentMongoRepository.findByRollNo(rollNo)                    , Student.class);             };     RouterFunction<ServerResponse> ...
