OpenApiWebMvcResource.openapiJson returning String is brittle if custom MessageConverters are present

[cfieber]

Is your feature request related to a problem? Please describe.
our app added a MessageConverter to support YAML content types and a JSON MessageConverter to add specific configuration of the Jackson ObjectMapper. As a result, the returned String gets serialized as a JSON String object (quoted and escaped) rather than as raw JSON

Describe the solution you'd like
Perhaps returning Map<String, Object> would play better with the Spring response serialization?

Describe alternatives you've considered
I need to figure out how to insert the correct MessageConverter to handle the String response through a WebMvcConfigurer

@cfieber,

You have so many ways to achieve your goal.
You can add StringHttpMessageConverter to your configureMessageConverters.
Or you can define your own OpenApiWebMvcResource Bean which returns what you are expecting...

All these options and others are discussed here:
