Get enum constant from @JsonProperty value

Question

I have an Enum marked with @JsonProperty for JSON serialization/deserialization with Jackson and would like to get the enum value for a given String JsonProperty:

Answer 1

The desired result can be achieved through the following method:

public static <T extends Enum<T>> T getEnumValueFromJsonProperty(Class<T> enumClass, String jsonPropertyValue) {
    Field[] fields = enumClass.getFields();
    for (int i=0; i<fields.length; i++) {
        if (fields[i].getAnnotation(JsonProperty.class).value().equals(jsonPropertyValue)) {
            return Enum.valueOf(enumClass, fields[i].getName());
        }
    }
    return null;
}
