What Spring Boot actually does with your configuration

The provided sources discuss Spring Boot development challenges. One author details the creation of spring-config-guard, a static-analysis CLI designed to detect security misconfigurations in application.yml and .properties files, such as exposed Actuator endpoints. This tool requires an accurate model of Spring Boot configuration resolution to avoid false reports. Another source focuses on diagnosing Postgres deadlocks in Spring Boot 3.x applications, emphasizing the importance of fixing lock-ordering bugs rather than using @Retryable to hide errors.
