configuration-properties/ @ConfigurationProperties vs @Value on Spring Boot 4.1.1. The relaxed-binding matrix is generated by binding each spelling rather than transcribed, and re-checked against real processes -- the in-process probe was wrong twice before it was right. Records the three findings that came out of it: @Value does get relaxed resolution inside Spring Boot (Boot attaches ConfigurationPropertySources), the configuration processor silently stops generating metadata on JDK 23+ when declared as a plain dependency, and @Valid is not what makes nested constraints run. profiles-and-config/ Precedence, profiles, spring.config.import and config trees. /precedence reports every source holding a property in rank order with file and line, which turns "my profile file had no effect" into a two-line answer. Also pins the counterintuitive one: an imported file outranks the file that imported it. spring-aop/ Designators, proxy types, and aspects that do not fire. One advice per supported designator so the reference table is generated from real matches; all fourteen unsupported designators fed to the parser. Two corrections to the reference documentation: unsupported designators throw UnsupportedPointcutPrimitiveException (extends RuntimeException, not IllegalArgumentException), and spring-boot-starter-aop was renamed to spring-boot-starter-aspectj in Boot 4. 19 contract tests across the three modules, 15 captured transcripts, all regenerated by scripts/run-all.sh. Verified on Spring Boot 4.1.1, Spring Framework 7.0.9, JDK 25.0.4.1. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Gip4srpzMwjgoba6uEfbr5

<!-- NOTE THE NAME. In Spring Boot 3 this was spring-boot-starter-aop. That artifact was
|
|
renamed to spring-boot-starter-aspectj during the Boot 4 milestones: its last
|
|
published version is 4.0.0-M2 and its last GA is 3.5.16, while
|
|
spring-boot-starter-aspectj starts at 4.0.0-M3. Copying an AOP dependency block out
|
|
of any pre-4 tutorial therefore fails resolution, because the old name is no longer
|
|
in the Boot BOM and therefore has no managed version.
|
|
|
|
Contents are unchanged: spring-boot-starter, spring-aop and aspectjweaver. It is
|
|
aspectjweaver that supplies the pointcut PARSER: Spring AOP does its own weaving
|
|
at runtime with proxies, and borrows only the expression language from AspectJ.
|
|
Without it, @Aspect classes are ordinary beans and every pointcut here silently
|
|
matches nothing. See docs/01-what-spring-aop-is.md. -->
