Spring Boot 2.2.6 没有为 Logback 的 SizeAndTimeBasedRollingPolicy 提供上下文

Question

When I use these configuration:

logging:
  file:
    name: app.log
    total-size-cap: 50MB
    max-size: 2MB
    max-history: 7
    path: logs

I get this information at application startup:

LOGBACK: No context given for c.q.l.core.rolling.SizeAndTimeBasedRollingPolicy@1818544933

When I create a dummy logback-spring.xml file there are no errors but application properties are ignored:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml" />
</configuration>

What I am missing at the configuration?

Answer 1

Looks like a legitimate issue. https://github.com/spring-projects/spring-boot/issues/21056 has a bugfix targeted to the next 2.2.x release. Sounds like adding logback-spring.xml to y

Answer 2

Firsyly, you can not use both 'name' and 'path'. It's either of them. Secondly, you need to set logging.config=/path/to/logback.xml
