Spring Boot Thymeleaf Input Type=radio für Enum Property

ExceptionOfExpectation · 17. Jun 2024

Hallo, ich habe ein spezifisches Problem, in meinem Form-Tag und zwar habe ich in <FieldSet> zwei Radio-Buttons, jeder von den beiden beinhaltet Werte und zwar enum Werte:

HTML:

<form action="#" th:action="@{/create-profile}" th:object="${profile}" method="post">
        ...
        
        
        <fieldset>
            <legend>Gender</legend>
            <input type="radio" id="male" th:fielde="*{gender}" th:value="${T(com.example.project.entity.Profile.Gender).Male}" required>
            <label for="male">Male</label><br>
            
            <input type="radio" id="female" th:field="*{gender}" th:value="${T(com.example.project.Profile.Gender).Female}">
            <label for="female">Female</label><br>
        </fieldset>
        
        <button type="submit">Submit</button>
    </form>

In meinem Entity habe ich das folgende Maßen gespeichert:

Java:

...
    private Gender gender;

    public enum Gender{Male, Female}
...

Und in der Mysql Datenbank:

SQL:

...
gender ENUM{"Male", "Female"} NOT NULL,
...

An sich funktioniert das zwischen Entity und Datenbank, aber es funktioniert nicht in dem Formular:

Code:

Das gender wird nicht übernommen.
Ich habe mit zwei Beans versucht: Converter<String, Profile.Gender> und AttributeConverter<String, Profile.Gender> den Fehlenden Schritt abzufangen, doch das hilft nicht. Wie passe ich das in meinem Formular an, damit es übernommen wird. Der Charakter Typ in meinem Datenbank ist nicht direkt schuld daran, das liegt eher an enum Klasse. In Thymeleaf Dokumentation steht darüber nichts, außer das was ich schon in meinem Beispiel übernommen habe. So gesehen brauche ich nicht mal den Package in meinem th:value, weil der Import wird aus der Kontroller Klasse übernommen.

ExceptionOfExpectation · 18. Jun 2024

Ich habe die Lösung für das Problem gefunden.
Zum einen habe ich in der Eigenschaft "th:fielde" einen TippFehler. Zum zweiten geht es viel leichter:

HTML:

<form action="#" th:action="@{/create-profile}" th:object="${profile}" method="post">
        ...
        
        
        <fieldset>
            <legend>Gender</legend>
            <input type="radio" id="male" th:field="*{gender}" th:value="Male" required>
            <label for="male">Male</label><br>
            
            <input type="radio" id="female" th:field="*{gender}" th:value="Female">
            <label for="female">Female</label><br>
        </fieldset>
        
        <button type="submit">Submit</button>
    </form>

Dabei muss man bedenken ich habe in meiner Enum kein direktes Value nur public enum {Male, Female} statt {Male("Male"), Female("Female")}
Man muss noch in der Entity die Enum Property anpassen:

Code:

@Enumerated(EnumType.STRING)
private enum gender;

Die zusätzliche Konverter waren überflüssig
