Rationalize Logback logging properties

Browse Source 
Deprecate and provide alternatives for logging properties that are
specific to Logback.

The following Spring Boot properties have been changed:

  * logging.pattern.rolling-file-name ->
    logging.logback.rollingpolicy.file-name-pattern

  * logging.file.clean-history-on-start ->
    logging.logback.rollingpolicy.clean-history-on-start

  * logging.file.max-size ->
    logging.logback.rollingpolicy.max-file-size

  * logging.file.total-size-cap ->
    logging.logback.rollingpolicy.total-size-cap

  * logging.file.max-history ->
    logging.logback.rollingpolicy.max-history

As have the system environment properties that they map to:

  * ROLLING_FILE_NAME_PATTERN ->
    LOGBACK_ROLLINGPOLICY_FILE_NAME_PATTERN

  * LOG_FILE_CLEAN_HISTORY_ON_START ->
    LOGBACK_ROLLINGPOLICY_CLEAN_HISTORY_ON_START

  * LOG_FILE_MAX_SIZE ->
    LOGBACK_ROLLINGPOLICY_MAX_FILE_SIZE

  * LOG_FILE_TOTAL_SIZE_CAP ->
    LOGBACK_ROLLINGPOLICY_TOTAL_SIZE_CAP

  * LOG_FILE_MAX_HISTORY ->
    LOGBACK_ROLLINGPOLICY_MAX_HISTORY

This commit also cleans up and simplifies `DefaultLogbackConfiguration`.

@ -2040,17 +2040,40 @@ The following table shows how the `logging.*` properties can be used together:
|=== |===
Log files rotate when they reach 10 MB and, as with console output, `ERROR`-level, `WARN`-level, and `INFO`-level messages are logged by default. Log files rotate when they reach 10 MB and, as with console output, `ERROR`-level, `WARN`-level, and `INFO`-level messages are logged by default.
Size limits can be changed using the configprop:logging.file.max-size[] property.
Rotated log files of the last 7 days are kept by default unless the configprop:logging.file.max-history[] property has been set.
The total size of log archives can be capped using configprop:logging.file.total-size-cap[].
When the total size of log archives exceeds that threshold, backups will be deleted.
To force log archive cleanup on application startup, use the configprop:logging.file.clean-history-on-start[] property.
TIP: Logging properties are independent of the actual logging infrastructure. TIP: Logging properties are independent of the actual logging infrastructure.
As a result, specific configuration keys (such as `logback.configurationFile` for Logback) are not managed by spring Boot. As a result, specific configuration keys (such as `logback.configurationFile` for Logback) are not managed by spring Boot.

=== File Rotation
If you are using the Logback, it's possible to fine-tune log rotation settings using your `application.properties` or `application.yaml` file.
For all other logging system, you'll need to configure rotation settings directly yourself (for example, if you use Log4J2 then you could add a `log4j.xml` file).
The following rotation policy properties are supported:
|===
| Name | Description
| configprop:logging.logback.rollingpolicy.file-name-pattern[]
| The filename pattern used to create log archives.
| configprop:logging.logback.rollingpolicy.clean-history-on-start[]
| If log archive cleanup should occur when the application starts.
| configprop:logging.logback.rollingpolicy.max-file-size[]
| The maximum size of log file before it's archived.
| configprop:logging.logback.rollingpolicy.total-size-cap[]
| The maximum amount of size log archives can take before being deleted.
| configprop:logging.logback.rollingpolicy.max-history[]
| The number of days to keep log archives (defaults to 7)
