Dies ist mein erstes Projekt in Spring Boot (Noob), ich wollte diesen Google Mail -Senden -Dienst erstellen, ich habe Code von einem Repository erhalten, aber es funktioniert nicht, ich habe offizielle Dokumente gesehen, aber sie geben Anmeldeinformationen durch JSON -Datei, hier übertrage ich diese Anmeldeinformationen als Objekt, aber es arbeitet jetzt. Debugging, Access Token generiert und auch Anmeldeinformationen generieren, aber wenn Google Mail.builder -Linie es ausführen, halt es nur dort an, tun Sie nichts, kein Fehler und nichts stoppen Sie die Ausführung < /p>
