Unable to generate javax.validation.constraints.DecimalMin and DecimalMax for type number

[abramsz]

I try to validate the conversion from json schema to java code in https://www.jsonschema2pojo.org/.
Only type of integer in schema can be used to geneate @DecimalMin("10"), for type of number, nothing has been generated.

With the following settings and json schema.

The following java code has been generated.

Thanks in advance.

Interestingly, the javadoc says this:

Note that double and float are not supported due to rounding errors (some providers might provide some approximative support).

So I guess this is why this applies only to integers. I guess we can add the annotation anyway. If it is not supported by some validators, I assume they will just ignore it.

I have found it here. From MinimumMaximumRule.java, it is prefer to use type BigDecimal instead of Double and Float.Let's close it.

    private boolean isApplicableType(JFieldVar field) {
        try {
            Class<?> fieldClass = Class.forName(field.type().boxify().fullName());
            // Support Strings and most number types except Double and Float, per docs on DecimalMax/Min annotations
            return String.class.isAssignableFrom(fieldClass) ||
                    (Number.class.isAssignableFrom(fieldClass) &&
                            !Float.class.isAssignableFrom(fieldClass) && !Double.class.isAssignableFrom(fieldClass));
        } catch (ClassNotFoundException ignore) {
            return false;
        }
    }
