Support use of @JsonValue on enums for CRD generation

[bbende]

Is your enhancement related to a problem? Please describe

I have a Java enum that is generated from an Open API spec, and the generated enum uses @JsonValue on a getter to indicate the value to use for serialization. It also generates a static fromValue method with @JsonCreator.

Example:

@JsonValue
public String getValue() {
    return this.value;
}

public String toString() {
    return String.valueOf(this.value);
}

    @JsonCreator
    public static MyEnum fromValue(String value) {
        MyEnum[] var1 = values();
        int var2 = var1.length;

        for(int var3 = 0; var3 < var2; ++var3) {
            MyEnum b = var1[var3];
            if (b.value.equals(value)) {
                return b;
            }
        }

        throw new IllegalArgumentException("Unexpected value '" + value + "'");
    }

I want to use this field in a custom resource that generates the CRD from the Java classes, but the generated CRD is not using the values from the method with @JsonValue, so the enum items have all the values from the name() method like VALUE_A , VALUE_B.

I assume this is because this code here only looks for @JsonProperty:

Describe the solution you'd like

I would like to see if it is possible to also consider @JsonValue in the code linked above that processes enumerations and looks for an alternate value to use for the enum value.

Describe alternatives you've considered
