Lots of miscellaneous definitions are being created in swagger, how can I limit these to a package?

• Version: 2.9.0

I’m currently running into an odd issue where I am getting a lot of miscellaneous models being added to my definitions. Is there a way to control which packages Springfox looks at for definition creation?

Here is my current configuration, which lives in a @Component that has @EnableSwagger2:

@Bean
Docket api() {
    return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.my.package.controller"))
            .build()
            .pathMapping('/')
}

and here is a small subset of the definitions being generated:

    "ASTNode": {
      "type": "object",
      "properties": {
        "columnNumber": {
          "type": "integer",
          "format": "int32"
        },
        "lastColumnNumber": {
          "type": "integer",
          "format": "int32"
        },
        "lastLineNumber": {
          "type": "integer",
          "format": "int32"
        },
        "lineNumber": {
          "type": "integer",
          "format": "int32"
        },
        "nodeMetaData": {
          "type": "object"
        },
        "sourcePosition": {
          "$ref": "#/definitions/ASTNode"
        },
        "text": {
          "type": "string"
        }
      },
      "title": "ASTNode"
    },
    "AnnotatedType": {
      "type": "object",
      "properties": {
        "annotations": {
          "type": "array",
          "items": {
            "$ref": "#/definitions/Annotation"
          }
        },
        "declaredAnnotations": {
          "type": "array",
          "items": {
            "$ref": "#/definitions/Annotation"
          }
        },
        "type": {
          "$ref": "#/definitions/Type"
        }
      },
      "title": "AnnotatedType"
    },
    "Annotation": {
      "type": "object",
      "title": "Annotation"
    },
    ```

@ahatzz11 thats awesome! glad you figured it out. Yes the meta class does cause additional models to be generated. However I did not realize how many. It would certainly be nice to add it, but thats not really part of this library. At the core, springfox doesnt/should not care about what the target language/framework is.

I just deleted all of my models except for one to test this out. This leftover model has a single String in it. When I generate my swagger through Springfox it is still pulling in all of these additional models. Here is the model TestRequest.groovy:

package com.my.package.hey

import com.fasterxml.jackson.annotation.JsonProperty
import groovy.transform.Canonical

@Canonical
class TestRequest {

    @JsonProperty('test_prop')
    String testProp
}

I tried to convert this model to a java class - TestRequest.java, and all of the extra models in the swagger spec disappeared. It seems there’s an issue with between groovy and springfox.

Some additional details:

groovyVersion = '2.4.15'
springBootVersion = '2.0.2.RELEASE'
springfoxVersion ='2.9.0'
swaggerVersion = '1.5.10'

I continued to play and I think I found a solution. I was looking at #752 and decided to try ignoring the groovy MetaClass in my docket creation.

.ignoredParameterTypes(MetaClass)

This ends up removing all of the extra classes that were created in the definitions.

Is this intended behavior? It would be cool if springfox was able to automatically filter out all the groovy classes that are found. This creates a lot of noise in swagger specs.
