SpringFox Generation

[pluttrell]

We've found this library to work great parsing and rendering MonetaryAmount instances as:

{
    "amount": 900,
    "currency": "USD"
}

However when SpringFox generates the Swagger docs on the same code, it describes the rendering as:

{
    "context": {
        "empty": true,
        "fixedScale": true,
        "maxScale": 0,
        "precision": 0,
        "providerName": "string"
    },
    "currency": {
        "context": {
            "empty": true,
            "providerName": "string"
        },
        "currencyCode": "string",
        "defaultFractionDigits": 0,
        "numericCode": 0
    }
}

Is there a way to solve this?

Does this still apply? https://stackoverflow.com/questions/41675459/springfox-swagger-generation-creates-odd-schema

I've never used springfox myself.

@pluttrell Have you managed to resolve this? I'll close this for now. I believe the stackoverflow answer gives some hints how to do this. Feel free to re-open, if needed.

@whiskeysierra Many thanks for getting back to me.

That SO answer suggests a mechanism where the rendering of one time is replaced with another, which is helpful in controlling how it renders. In the example, it uses a Double.class or String.class, which if one used Double.class would render it in SpringFox simply as:

0

So to use that method, we'd need a type to use. In looking through the zalando/jackson-datatype-money codebase and it doesn't look like there's a specific class to use as it uses com.fasterxml.jackson.databind.JsonSerializer to render the instances.

If one create a class just for this purpose, such as the following:

class ZalandoJacksonDataTypeMoneyRenderedMonetaryAmount{
  private double amount;
  private String currency;
  private ZalandoJacksonDataTypeMoneyRenderedMonetaryAmount() {}
  public double getAmount() { return amount; }
  public void setAmount(double amount) { this.amount = amount; }
  public String getCurrency() { return currency;}
  public void setCurrency(String currency) { this.currency = currency; }
}

SpringFox then renders MonetaryAmounts as:

{
    "amount": 0,
    "currency": "string"
}
