For simple custom constraints (which do not make a DB call or need autowiring inside the validation class), please refer to here. This Gist is about how to make Database calls through autowired Spring JPA Repositories as part of the constraint validation.

Use Case:

• My Table has 3 columns - id, role and user_id. Now there can be only 1 row for which role can take the value ROLE_ROOT. And once that record is inserted, it can't be updated.

How I am implementing:

This gist describes usage of helm umbrella charts to manage deployment of multiple micro-services to kubernetes

Developers can maintain a separate Github repo for base helm charts.

A base-microservice chart will have all sorts of kubernetes templates like HPA,ConfigMap,Secrets,Deployment,Service,Ingress etc , each having the option to be enabled or disabled.

And the base chart can even contain other public charts as dependency.

Now in each microservice, we will have a dedicated chart defining a dependency of this base-microservice chart

Two approaches to handle error responses from Spring WebClient calls globally:

• Exceptions with webclients are all wrapped in WebClientResponseException class. So we can handle that using Spring's ExceptionHandler annotation.

• Using ExchangeFilterFunction while constructing the webclient bean.
