How to fix duplicate entries in different log files using Logback/SpringBoot?

edit

To fix duplicate entries in different log files using Logback/SpringBoot, follow these steps:

1. Identify the source of duplicate entries: Analyze the log files to identify where the duplicates are coming from. This can help you pinpoint the cause of the issue.

2. Check Logback's configuration: Make sure that Logback is correctly configured and not duplicating log entries. Verify whether Logback is set up to write to multiple output files or not.

3. Review SpringBoot's configuration: SpringBoot provides its own logging framework, so you may need to check SpringBoot's configuration to ensure that it is not causing logging duplication.

4. Use log level filtering: Check whether you have set the appropriate log level filter. Some log messages may be appearing twice due to a low log level filter.

5. Use unique file names: Ensure that your log file names are unique. Log files with identical names can get overwritten or duplicate entries may appear in both.

6. Use the LOGBACKCONFIGURATIONFILE property: Configure Logback using the LOGBACKCONFIGURATIONFILE property. This can help you specify the logging settings for each application module separately.

7. Use the conditional logging feature: Logback provides a conditional logging feature that allows log statements to be printed conditionally. This can help you avoid duplicate entries.

8. Remove redundant logging: Remove any redundant logging statements that may be causing duplicate log entries.

By following these steps, you can fix duplicate entries in different log files using Logback/SpringBoot.
