Error in Spring Cloud + Logback

Original Source: Spring Cloud program uses logback error

Spring Cloud program uses logback error

Let me start with the conclusion

For Spring Cloud programs that do not use Spring Cloud Context, it is best to disable Spring Cloud Context, because if it is not disabled, it will cause some configuration loading errors. Disable method: add in the main SpringBoot function System.setProperty("spring.cloud.bootstrap.enabled", "false");
