Logging Config

Src/main/Logback-spring.xml – logging config
Want logging to be minimal, useful, but not affect performance
For debug use level=”debug”
Appender tells whether logs go to file or console or whatever
maxHistory=5 means 5 days
max file size is 5Mb – if a file fills up, then an index is appended and a new file created (eg mything.log for current and mything.2017-12-01.1.log for filled up log), and the previous file is renamed with the date stamp of the date the file filled up
default log location is same location as jar file

Environment-specific details, urls, access tokens etc are in src/main/resources/Application.yml
How are settings from application.yml used?
- See VendorProperties (myproject-backend\src\main\java\com\myproject\backend\config\VendorProperties.java)
- This class gets injected into most other classes using SpringBoot’s default dependency injection.
- For instance, you’ll see private var browserCacheTime in BrandDetail, and access functions getBrowserCacheTime and setBrowserCacheTime.
- Also check out the SpringBoot annotations, ie @Configuration, @EnableConfigurationProperties and @ConfigurationProperties. These are what allow the VendorProperties to automatically take values from application.yml
  - If you look in application.yml, you’ll see there is a section headed vendor: - this is indicated in VendorProperties by prefix=”vendor” at the top.
  - You’ll also see the VendorProperties access method setBrands and the member var brands – I believe these relate to the section headed brands: in application.yml.
  - There is a simple example here: http://www.baeldung.com/configuration-properties-in-spring-boot
