Eliminar o Ribbon de hr-payroll:
- Dependência Maven
- Annotation no programa principal
- Configuração em application.properties
Atenção: aguardar um pouco depois de subir os microsserviços
server.port=${PORT:0}
eureka.instance.instance-id=${spring.application.name}:${spring.application.instance_id:${random.value}}
Atenção: deletar as configurações múltiplas de execução de hr-worker
Atenção: testar antes sem a annotation do Hystrix
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=60000
ribbon.ConnectTimeout=10000
ribbon.ReadTimeout=20000
Porta padrão: 8765
Mesmo o timeout de Hystrix e Ribbon configurado em um microsserviço, se o Zuul não tiver seu timeout configurado, para ele será um problema de timeout. Então precisamos configurar o timeout no Zuul.
Se o timeout estiver configurado somente em Zuul, o Hystrix vai chamar o método alternativo no microsserviço específico.
Quando um microsserviço é levantado, antes de se registrar no Eureka, ele busca as configurações no repositório central de configurações.
hr-worker.properties
test.config=My config value default profile
hr-worker-test.properties
test.config=My config value test profile
Teste:
http://localhost:8888/hr-worker/default
http://localhost:8888/hr-worker/test
No arquivo bootstrap.properties configuramos somente o que for relacionado com o servidor de configuração, e também o profile do projeto.
Atenção: as configurações do bootstrap.properties tem prioridade sobre as do application.properties
Atenção: colocar @RefreshScope em toda classe que possua algum acesso às configurações
Atenção: reinicie a IDE depois de adicionar as variáveis de ambiente
