Spring Boot 3 Compatibility

[3.0.0] - 2023-2-11

Add support for Spring Boot 3 projects. With this version we now support Spring Boot 1, Spring Boot 2 and Spring Boot 3 projects. The minimum JDK required is JDK 8.

Added

• Several new maven modules were added to support Spring Boot 3
• upbanner now supports examining jar files using the Spring Boot 3 jar file format
• added org.springframework.boot.autoconfigure.AutoConfiguration.imports

Changes

• Building this project now requires jdk 17, but the resulting artifacts can still be used by a project that is using JDK 8.
• Some of the modules have tests that require JDK 8 to execute. They will not work with a newer JDK. See fullbuild.sh for details.
• renamed whatsupbanner root level pom to upbanner
• The module dependencies now look like this:
  • com.garyclayburg:upbanner-starter:3.0.0
    • com.garyclayburg:upbanner-core:3.0.0
      • com.garyclayburg:upbanner-nestedjar:3.0.0
        • com.garyclayburg:upbanner-probes:3.0.0
      • com.garyclayburg:upbanner-probes:3.0.0

Fixed

• Sometimes upbanner would print http://localhost:443 when it should have been https: instead
• docker detection now works with modern docker engines

Removed

• BuildPropertiesStub is no longer needed
• some JarFile @beans are no longer needed since the objects are created much earlier in the startup process.

upbanner.debug phase improvements

[2.3.0] - 2021-4-23

upbanner.debug phase improvements

Added

• debug: now show all enumerable properties available to the application and their source location
• debug: new comprehensive external property override report. For example, this application has server.port defined in 2 places:

--- properties OVERRIDDEN report ---
java.home=/usr/lib/jvm/java-8-oracle/jre (from environment)
  java.home=/usr/lib/jvm/java-8-oracle/jre (from configurationProperties)
    java.home=/usr/lib/jvm/java-8-oracle/jre (from systemProperties)
      java.home=/usr/lib/jvm/java-8-oracle (from systemEnvironment)
server.port=8040 (from environment)
  server.port=8040 (from configurationProperties)
    server.port=8040 (from systemProperties)
      server.port=8050 (from applicationConfig: [classpath:/config/application-dev.yml])

Changes

• debug: phase now occurs before any beans are constructed during startup sequence
• debug: system environment and properties are now printed alongside other properties, with their source location
• debug: all property names are now printed in sorted order
• debug: @PostConstruct method is no longer needed if you want to customize upbanner. The debug phase is now invoked automatically before application beans are even constructed. See Readme.md Customizing
