For example, with RxJava we can use Observable. Javalin, Micronaut, Spark and many more make building REST APIs a breeze. For example, a value of "ServletException" would match javax. One of the biggest advantages of microservices is to address these concerns: instead of building an entire application as one block, one can build it as a set of services which will communicate over some kind of messaging system (most of the time, REST over HTTP). Micronaut feels intuitive and coming from Spring I think it is even easier. The Struts 2 user mailing list is an excellent place to get help. Several frameworks already support this out of the box such as Helidon SE, Quarkus and Micronaut. Rather than do runtime annotation processing as Spring Boot and MicroProfile, Micronaut uses annotation processors at compile time to generate additional classes that are compiled alongside your code.

For example, the Java programming languages provides the ability for developers to place annotations on code, which adds declarative capabilities to traditionally developed code. With its speed, low memory foot print, easiness of configuration (or none of it :)) and a nice set of bundled dependencies I perceive it as a growing competitor to Spring Boot. This is achieved primarily through a brand new DI/AOP container, which performs dependency injection at compile-time rather than runtime. The following example Gradle build file adds the Gradle Asciidoctor plugin, Spring REST Docs dependencies and configures the test and asciidoctor tasks. Because part of the initialization is done at build time, Quarkus has a reduced startup time. An instance of MicronautBeanProcessor should be added to the Spring Application Context.
