Use when introducing or correcting grouped Spring Boot configuration, typed property binding, validation, profiles or secret injection. Do not rewrite unrelated single-value configuration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Configuration Properties ## Spring Boot 3 baseline The examples use Java 17 and Jakarta APIs supported by this Boot version. Keep dependencies managed by the project's Boot BOM. ## Bind and validate Inspect existing property prefixes and external deployment configuration before renaming keys. Use a typed ConfigurationProperties record for a related group of settings. Register it with EnableConfigurationProperties or ConfigurationPropertiesScan; a record is not automatically a bean. Use Validated and Jakarta constraints, and include spring-boot-starter-validation. Validate nested objects with Valid. A single record constructor needs no ConstructorBinding annotation. Use explicit units for durations and sizes. Provide defaults only when they are operationally safe; missing credentials or required endpoints should fail startup. Do not assume NotNull rejects zero or negative Duration values; add a duration constraint or an explicit invariant. [ClientProperties](examples/ClientProperties.java) and [its configuration](examples/good-client.yml) show a validated prefix with explicit duration units. …

How to install
mdr add rrezartprebreza/spring-boot-skills/configuration-properties@sha256:7f7236e1819d7ed4The line at the top of this page pins the label git:20260907.13f9ef2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
