Spring Boot best practices separate configuration from code and enforce startup validation
↗
Spring Boot configuration management guidelines recommend externalizing settings and validating required values at startup
Engineers building Spring Boot applications must handle configuration across environments without embedding secrets or environment-specific values in code. These practices reduce deployment errors and security risks by enforcing validation and immutability. The guidance directly impacts how configuration is structured, injected, and secured in production systems

Configuration should be externalized and classified into application defaults, deployment settings, and secrets
@ConfigurationProperties enables type-safe binding and validation of related properties over scattered @Value annotations
Java records provide immutable configuration objects to prevent accidental runtime modification
