Hibernate Validator Enum

So, null & unknown value handling for enum has always been an issue for me when converting from JSON to Java.

I saw an implementation on Amazon Java SDK packages. Really liked the design, I expanded on it to support JSON using the Jackson packages. I have also created @ValidEnum constraints to support using Hibernate Validator library.

This project consist of

• IntelliJ Live Template
• ValidEnum annotation
• JSON, Jackson support
• Enum null, unknown value handling.

Examples

Creating the enum with live template

Using the live template to create enum, my keyword is: UNKNOWN_TO_SDK_VERSION

public enum Status {
    ALLOWED("ALLOWED"),
    UNKNOWN_TO_SDK_VERSION(null);

    private final String value;

    Status(String value) {
        this.value = value;
    }

    @Override
    @JsonValue
    public String toString() {
        return String.valueOf(value);
    }

    /**
     * Use this in place of valueOf to convert the raw string returned by the service into the enum value.
     *
     * @param value real value
     * @return Status corresponding to the value
     */
    @JsonCreator
    public static Status fromValue(String value) {
        if (value == null) {
            return null;
        }
        return Stream.of(Status.values()).filter(e -> e.toString().equals(value)).findFirst()
                .orElse(UNKNOWN_TO_SDK_VERSION);
    }

    public static Set<Status> knownValues() {
        return Stream.of(values()).filter(v -> v != UNKNOWN_TO_SDK_VERSION).collect(Collectors.toSet());
    }
}

Adding bean validation

public class Bean {
    @ValidEnum
    public Status status;
}
