Sie wissen nicht, was falsch läuft. Bitte helfen Sie mir, diese Warnung loszuwerden, da sie andere Probleme verursacht.

Answer 1

Aus meiner Forschung bezieht sich dies auf eine veraltete Verbindung oder nicht korrekt Verbindungen zu schließen. Ich habe das zugehörige Ticket here gefunden. Bitte überprüfen Sie und lassen Sie mich wissen, wenn das hilft. Wenn nicht, können Sie weitere Informationen zu Ihrer Umgebung bereitstellen. Tomcat Vollversion? Sieht so aus, als ob du Hibernate benutzt. Welche Version? Gibt es noch andere Fehler, wie zum Beispiel in Ihrer Anwendungsprotokollierung?
