So speichern Sie Konsolenprotokolle im SpringBoot-Projekt

Konfiguration zum Speichern des SpringBoot-Konsolenprotokolls

Szenario: Das Konsolenprotokoll muss im SpringBoot-Projekt gespeichert werden.

Implementierungsmethode:

1. Konfigurieren Sie die Konfigurationsdatei application-prod.yml

wie folgt:

logging:
  config: classpath:logback-spring-prod.xml

2 .logback-spring-prod.xml

Diese Datei ist der Pfad, in dem das Konsolendruckprotokoll gespeichert wird, und ist wie folgt konfiguriert:

<?xml version="1.0" encoding="UTF-8"?>
