Now that we have a handler, we can connect it to our previously created reactive services. Let's first bind them in our handle through the constructor and use it:
@Componentclass CustomerHandler(val customerService: CustomerService) { fun get(serverRequest: ServerRequest) = ok().body(customerService.getCustomer(1), Customer::class.java)}
If we try to run this example now, we will get a compilation error and this is because our service method was defined as:
fun getCustomer(id: Int): Mono<Customer?>
Since Customer is nullable, we cannot bind to Customer::class.java, so let's modify our service interface:
package com.microservices.chapter4import reactor.core.publisher.Fluximport reactor.core.publisher.Monointerface ...
