[Guest]

Ich habe ein Java -Projekt, das auf einem Webserver ausgeführt wird. Ich habe diese Ausnahme immer erreicht. >
Aber ich konnte kein klares Beispiel finden, das erklärt, wie man es verwendet. < /p>
Meine Methode ist wie: < /p>

Code: Select all

    @Transactional
public void test(Email email, String subject) {
getEmailById(String id);
email.setSubject(subject);
updateEmail(email);
}
< /code>
while: < /p>

[*]Email

ist eine Hibernate -Klasse (es ist eine Tabelle in der Datenbank)
[*]

Code: Select all

getEmailById(String id)

ist eine Funktion, die eine E -Mail zurückgibt (diese Methode wird nicht mit @transactional )
kommentiert

Code: Select all

updateEmail(email)

: Ist eine Methode, die die E -Mail aktualisiert. auf (Beispiel: Session.getCurrentSession.save (E -Mail) )
Die Ausnahme:

Code: Select all
