Apis that return a generic type (Foo<T>) where T is an ENUM overrides APIs that return a T that is a String

Hi

An issue appears to exist with Enum’s and generic types where if we have two APIs that return:

• ResponseWrapper<String>
• ResponseWrapper<MyEnum Then I find that the generated swagger json contains:

"ResponseWrapper«string»": {
      "properties": {
        "data": {
          "allowEmptyValue": false,
          "description": "...",
          "enum": [
            "FOO",
            "BAR"
          ],
          "type": "string"
        },
        "errorMessage": {
          "allowEmptyValue": false,
          "description": "If a error occurs a user friendly message may be placed here.",
          "type": "string"
        }
      },
      "title": "ResponseWrapper«string»",
      "type": "object"
    }

So now swagger thinks that for anything that returns a ResponseWrapper<String> it is restricted to the values of the enum. This is particularly problematic when a client is generated from the JSON. As ResponseWrapper<String> is made to return a ResponseWrapper<MyEnum> instead.

I appear to be depending on:

            <dependency>
                <groupId>io.swagger</groupId>
                <artifactId>swagger-annotations</artifactId>
                <version>1.5.19</version>
            </dependency>
            <dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger2</artifactId>
                <version>2.8.0</version>
            </dependency>

A fix for this would be highly appreciated! Thank you!

I worked around the problem by extending my class e.g.

class MyEnumResponseWrapper extends ResponseWrapper<MyEnum>

the down side is each person needs to remember to actually do that.
