You need to add the spring boot configuration processor to your project; when using maven add this dependency:

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-configuration-processor</artifactId>
  <optional>true</optional>
</dependency>

You find more information in the spring boot documentation.
