Fluent -style builder API support. #3431
Description
I am thinking of providing a fluent -style builder API built on ServiceConfig, ReferenceConfig, ...
It may work like this:
ApplicationConfig applicationConfig = ApplicationBuilder.name("demo").build();
ServiceConfig serviceConfig = ServiceBuilder.ref(ref).timeout(1000).build();
ReferenceConfig referenceConfig = ReferenceBuilder.interface("interface name").timeout(2000).build();
DubboBuilder dubboBuilder = DubboBuilder.application(applicationConfig).registry(registryConfig).protocol(protocol);
// To trigger the export/refer process, you can just start dubboBuilder
dubboBuilder.services(Arrays.asList(serviceConfig)).references(Arrays.asList(referenceConfig)).start();
// Or, you can export/refer one specific Service or Reference
dubboBuilder.export(serviceConfig);
dubboBuilder.refer(referenceConfig);At present, one of the problems of using ServiceConfig and ReferenceConfig directly is that some application-level configurations need to be set to each ServiceConfig or ReferenceConfig, which is redundant, unnecessary and inconvenient for users
ApplicationConfig application = new ApplicationConfig();
ServiceConfig serviceConfig1 = new ServiceConfig();
serviceConfig1.setApplication(application);
serviceConfig1.export();
ServiceConfig serviceConfig2 = new ServiceConfig();
serviceConfig2.setApplication(application);
serviceConfig2.export();
