[[boot-features-external-config-relaxed-binding]] -==== Relaxed binding (Properties format) +==== Relaxed binding Spring Boot uses some relaxed rules for binding `Environment` properties to `@ConfigurationProperties` beans, so there doesn't need to be an exact match between the `Environment` property name and the bean property name. Common examples where this is useful include underscore separated (e.g. `context_path` binds to `contextPath`), and capitalized (e.g. `PORT` binds to `port`) environment properties. -NOTE: Environment variables are usually underscore-separated and upper case so you can -just use that and Spring Boot will bind it to your bean property names accordingly.
