Spring HATEOAS
This version is still in development and is not considered stable yet. For the latest stable version, please use Spring Boot 4.1.1!

If you develop a RESTful API that makes use of hypermedia, Spring Boot provides auto-configuration for Spring HATEOAS that works well with most applications. The auto-configuration replaces the need to use @EnableHypermediaSupport and registers a number of beans to ease building hypermedia-based applications, including a LinkDiscoverers (for client side support) and an JsonMapper configured to correctly marshal responses into the desired representation. The JsonMapper is customized by setting the various spring.jackson.* properties or, if any exist, the JsonMapperBuilderCustomizer beans.

You can take control of Spring HATEOAS’s configuration by using @EnableHypermediaSupport. Note that doing so disables the JsonMapper customization described earlier.
spring-boot-starter-hateoas is specific to Spring MVC and should not be combined with Spring WebFlux. In order to use Spring HATEOAS with Spring WebFlux, you can add a direct dependency on org.springframework.hateoas:spring-hateoas along with spring-boot-starter-webflux.

By default, requests that accept application/json will receive an application/hal+json response. To disable this behavior set spring.hateoas.use-hal-as-default-json-media-type to false and define a HypermediaMappingInformation or HalConfiguration to configure Spring HATEOAS to meet the needs of your application and its clients.
