ControllerAdvice and ModelAttribute

[donhill]

I have several endpoints which take for example a user ID. When sending a query that invokes several routes I want to perform something like an interceptor that will allow us to inject a model from another service into the router so That each route doesn't have to call the same service.

Is there something like @ControllerAdvice in this library?

Do you mean several queries? i.e. something along the lines

type Query {
  foo(id: ID!): Foo
  bar(id: ID!): Bar
  baz(id: ID!): Baz
}

Each one of those fields is resolved independently of each other. You definitely could use aspects around queries but IMHO that approach would rather be error prone and potentially could be simplified. If you need to fetch some common data for each one of those fields, maybe you could refactor the schema so they have common parent?

type Query {
  # function returns FooBarBaz that has common data that could be stored in private fields
  fooBarBaz(id: ID!): FooBarBaz
}

type FooBarBaz {
  # functions that return specific objects based on some common data from parent
  foo: Foo
  bar: Bar
  baz: Baz
}
