swagger @ApiModelProperty example value for List property

I managed to get this to work, generating a List of Strings.

Within the ApiModelProperty with springfox 2, write your example as follows:

example = "[\"AddLine1\",\"AddLine2\",\"AddLine3\",\"AddLine4\"]"

Here is my example:

@ApiModelProperty(value = "Address", name = "addLines", 
    example = "[\"AddLine1\",\"AddLine2\",\"AddLine3\",\"AddLine4\"]")

When I render the swagger page, I get the following output:

"addLines": [
      "AddLine1",
      "AddLine2",
      "AddLine3",
      "AddLine4"
    ],

TLDR: One of the contributers on Swagger-API has worked on this functionality to add this in version 3.0.0 but it’s not sure yet when this will be released. For now it stands on the feature/3.0.0-rc2 branch at the Swagger-API GitHub

I’ve been working with Swagger for almost two months now and as our project progressed issues like this showed up. Now I did some research and read on the GitHub pages for the Swagger-API that this feature simply doesn’t work (yet).

As described here and [here would be an other link but my reputation is not high enough to post more than 2 links] this feature has been requested several times since August 2015 with not much luck.

Now on this issue on the Swagger-API github, one of the contributors commented:

This takes a major refactoring of the models, which is on the way. 3 March 2017

which lead to a later comment:

Will be supported in 3.0.0 support, please see the feature/3.0.0-rc2 branch for details. 27 June 2017

And on 9 August 2017 someone asked when the release of version 3.0.0 would be with no further response.

So in conclusion, support for examples for arrays/Lists has been worked on and should be available in version 3.0.0 but no more news on when that would be released.

You just use Reflection notation. Using

@ApiModelProperty(dataType = "[Ljava.lang.String;")

works fine, but I can’t put examples.

This is the result:

{
  "field": [
    "string"
  ]
}

Try to initialize @ApiModelProperty as follows:

public class MyClass {
    ....
    @ApiModelProperty(
        position = 2, datatype="List", example = "PRD1, PRD2, PRD3"
    )
    private List<String> productIdentifiers;
    ....
}
