How to add example in an API response without losing Schema

How to add example in an API response without losing the Schema?

This case is based on Java Map object for Json representation.

i.e. if I use the following
@ApiResponse(responseCode = "200", description = "OK")

I get the following correct response

"responses": {
          "200": {
            "description": "OK",
            "content": {
              "application/json": {
                "schema": {
                  "type": "object",
                  "additionalProperties": {
                    "type": "object"
                  }
                }
              }
            }
          }

But if I modify the @ApiResponse to add an example using the following

@ApiResponse(responseCode = "200", description = "OK",
			content = @Content(examples = {@ExampleObject(value = "{\"Key\": \"Value\"}")})
	)

Then the response object is now incorrect.

"responses": {
          "200": {
            "description": "OK",
            "content": {
              "application/json": {
                "example": {
                  "Key": "Value"
                }
              }
            }
          }
        }

The Schema gets removed.

So - how would I add a example to the existing @ApiResponse without losing the schema? Is this a bug?

I have created a unit test in the following branch for app51.
https://github.com/ianwallen/springdoc-openapi/tree/how_to_add_example_response_json

It produced the following error.

java.lang.AssertionError: paths./test5.post.responses.200.content.application/json
Expected: schema
     but none found

Thank you

Hello,

I have the same issue when migrating from Springfox. It seems like in order to get the default schema on Springfox, the @content must either not be defined, or defined with all attributes without any defaults generated.
I was also hoping that useReturnSchema=true would be taken into account, but it has no effect as well.

If this is somehow an expected behavior due to OpeanAPI specs (or in general a breaking change), can you at least consider a config property which would allow this?

In project I'm part of, we try to minimise the amount of manual API doc definitions for internal APIs and this one seems like a good candidate for an intuitive default behavior - unless I'm missing the issue here, of course.

@ianwallen,

As long a you added the@Content annotation, it will be used for reference.
You need to complete it with your Schema response, for example:

@ApiResponse(responseCode = "200", description = "OK",
	content = @Content(schema = @Schema(type = "object", additionalPropertiesSchema = Object.class), examples = {@ExampleObject(value = "{\"Key\": \"Value\"}")})
)
