The logfile in the configuration center does not take effect for actuator

This enhancement request comes from this problem

Also,This looks to be very similar to this problem with Spring Cloud Config which was closed as feedback was not provided.

• environment
  • SpringBoot:2.6.8
  • SpringCloud:2021.0.2
  • SpringCloudAlibaba:2021.0.1.0
  • nacos:2.1.0
• important step
  1. pom.xml add dependency spring-boot-starter-actuator
  2. modify the configuration
     • Add the following configuration to bootstrap.yml or application.yml

       logging:
         file:
           name: ./log/a.log
       

     • Add the following configuration in the nacos configuration center

       management:
         endpoints:
           web:
             exposure:
               include: "logfile" # enable log endpoint
       logging:
         file:
           name: ./log/b.log
       

  3. start server
  4. Open the log folder, Contains two files a.log and b.log, Logs are refreshed in b.log
• issue
  • Browser open url http://[ip]:[port]/actuator/logfile，Only the file content of a.log is displayed
  • If logging.file.name is not configured in bootstrap.yml or application.yml, A 404 error code is displayed when visit the url
• a complete yet minimal sample, include documentation
  • https://github.com/Max-Qiu/test-logfile

Start with the linked minimal sample and its pom.xml, then reproduce the behavior using bootstrap.yml or application.yml and the Nacos configuration shown in the issue. Check the actuator/logfile endpoint with logging.file.name defined locally and remotely. Done means the endpoint reflects the effective configuration-center logfile, including the case where no local logging.file.name is configured.
