I've updated the code simpler using java record.

This lets you use a Spring Boot user-custom property called
spring.thymeleaf3.decoupled-logicto turn on/off the decoupled logic feature for Thymeleaf 3.Use this property inside
application.propertiesorapplication.yamlto activate Thymeleaf 3 decoupled logic.I personally feel weird that Spring Boot common application properties for Thymeleaf isn't taking care of this option by these days as it's not a difficult thing to provide at all,
even though this feature seems not so popular to Spring Boot and Thymeleaf users.
이 스프링 부트 설정은 사용자 정의 프로퍼티
spring.thymeleaf3.decoupled-logic을 사용하여 타임리프 3의 템플릿 로직 분리(decoupled logic) 기능을 이용할 수 있게 해줍니다.application.properties혹은application.yaml에서 사용하여 템플릿 로직 분리 옵션을 제어해 보세요.저는 개인적으로 이 옵션이 스프링 부트 애플리케이션 프로퍼티에서 설정할 수 있도록 제공되지 않는다는 사실이 이상하게 느껴집니다. 세팅이 어려운 부분이 아니기 때문에요.
비록 스프링 부트와 타임리프 유저들에게 그렇게 인기있는 기능은 아니라 하더라도요.
I made the prefix of the property to
spring.thymeleaf3, it might have been smoother to usespring.thymealeafinstead, but I chose not to do that way to avoid confusion.This is as far as I know the simplest and the most graceful way to use decoupled logic in Spring Boot.
Also, I suggest you use this Spring Boot configuration with the dependency
spring-boot-configuration-processorfor better IDE support and experience.프로퍼티 앞글자는
spring.thymeleaf3로 지었습니다.spring.thymealeaf로 지었으면 더 좋았겠지만, 혼란을 피하기 위해 구분을 두었습니다.제가 아는 한 이것이 스프링 부트에서 타임리프 로직 분리기능을 가장 쉽고 우아하게 사용할 수 있는 방법입니다.
또한, 이 프로퍼티를
spring-boot-configuration-processor스프링 부트 디펜던시와 함께 사용하여 IDE 의 지원과 나은 경험을 느껴보세요.Tested on
Spring Boot 2.7.0+thymeleaf 3.0.15Reference
