For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'.

Auch wenn ich nicht verwenden ** Maven ** i die gleiche Ausnahme bin immer, ich von einer Woche versucht haben, dabei helfen mir keine Lösung bis jetzt jemand bitte thing.what ist der Grund ** ** für Dies?????????? –
versuchen Sie Folgendes: @Column private String name; anstelle des privaten String-Namens; in Entitätsklasse – Nidhi257
Können Sie Ihren genauen Tabellennamen freigeben oder Tabellen-SQL erstellen? –
