+The method validation feature supported by Bean Validation 1.1 is automatically enabled as long as a JSR-303 implementation (such as Hibernate Validator, typically provided by `spring-boot-starter-validation`) is on the classpath.
 This lets bean methods be annotated with `jakarta.validation` constraints on their parameters and/or on their return value.
 Target classes with such annotated methods need to be annotated with the javadoc:org.springframework.validation.annotation.Validated[format=annotation] annotation at the type level for their methods to be searched for inline constraint annotations.
