The variable's value is passed into the operation method when the endpoint operation is invoked. If you want to capture all remaining path elements, you can add @Selector(Match=ALL_REMAINING) to the last parameter and make it a type that is conversion compatible with a String[]. We created a custom annotation and password constraint validator for this and used it in our instance variable, and the actual business logic was implemented in a separate class.

Juergen Hoeller commented The problem here is that JSR-303 is only really defined for bean classes: The constraint annotations are expected to sit on the target model class. As a consequence, @Valid on a parameter with primitive type doesn't mean anything since the primitive type doesn't contain any constraint annotations. Spring Boot allows us to define validation criteria using annotations. In your Domain Model, you can simply annotate fields with the constraints, and it'll enforce them. For the validation annotations to work we need to add the following dependency: <dependency> <groupId> org.springframework.boot </groupId> <artifactId> spring-boot-starter. Note the syntax %regex[expr], where expr is the actual expression and the rest is just wrapping. Also note the following about the use of regular expressions: Regex matches are done over *.class files and not *.java files; Regex matches are done over paths using slashes ("/") and not package names using dots ("."), so the "." in pkg.*Slow.*.class is a regex metacharacter, which happens to.
