There have been many improvements and refinements to the actuator endpoints with Spring Boot 2.0. Spring Boot 2.0 now includes support for Kotlin 1.2.x and offers a function runApplicationВ which provides a way to run a Spring Boot application using Kotlin. Support depends on the chosen web server and the application environment. HTTP/2 support is provided for Tomcat, Undertow and Jetty. The starter spring-boot-starter-webflux POM will pull-in Netty 4.1 andВ Reactor Netty. Since WebFlux does not rely on Servlet APIs, Spring Boot is now able to support Netty as an embedded server for the first time. If youвЂ™ve used Spring Security with Spring MVC before, this should feel quite familiar. Access rules for Spring Security with WebFlux can be configured via a SecurityWebFilterChain. Auto-configuration is provided for WebFlux applications whenever Spring Security is on the classpath. Spring Boot 2.0 can make use of Spring Security 5.0 to secure your reactive applications.

For example, spring-boot-starter-data-mongodb-reactiveВ includes dependencies to the reactive mongo driver and project reactor. Spring Boot includes special starter-POMs for these technologies that provide everything you need to get started. Currently, Cassandra, MongoDB, Couchbase and Redis all have reactive API support. Where the underlying technology enables it, Spring Data also provides support for reactive applications. To get started, use the starter spring-boot-starter-webflux POM which will provide Spring WebFlux backed by an embedded Netty server. Spring Boot provides auto-configuration for both annotation-based Spring WebFlux applications, as well as WebFlux.fn which offers a more functional style API. Spring WebFlux is a fully non-blocking reactive alternative to Spring MVC. The internals of Spring Boot itself has also been updated where necessary to offer reactive alternatives. Spring Boot 2.0 fully supports reactive applications via auto-configuration and starter-POMs.

TheyвЂ™re intended for use in an event-loop execution model (instead of the more traditional one thread-per-request execution model). Reactive applications are fully asynchronous and non-blocking. Many projects in the Spring portfolio are now providing first-class support for developing reactive applications. Some notable dependency upgrades in 2.1 release include: Some notable dependency upgrades in 2.0 release include: Spring Boot has upgraded to the latest stable releases of other third-party jars wherever it possible. Spring Boot 2.0 requires Spring Framework 5, while Spring Boot 2.1 requires Spring Framework 5.1.
