reserved. Modern JVM Framework ❖ Micronaut was designed from scratch in 2017, focused on modern architectures like microservices and serverless, with the cloud in mind. 6 All application types ❖ Micronaut is a complete solution for any type of application: microservices, message-driven producers or consumers, command- line apps, serverless functions Highly optimized ❖ Micronaut leverages Java annotation processors and other optimizations to compute the framework infrastructure at compile- time, drastically reducing startup time and memory consumption.
reserved. AOT: Ahead of Time Micronaut computes at build time: ‣ All dependency and configuration injection ‣ Annotation metadata (meta annotations) ‣ AOP proxies ‣ Bean introspections ‣ All other framework infrastructure At runtime ‣ No reflection. ‣ No proxy generation. ‣ No dynamic classloading. ‣ No classpath scanning. 8
reserved. Configuration Dependency Injection ❖ Can use JSR-330 (@Inject) annotations 9 ❖ Properties, YAML, TOML, Groovy, Config4K. Validation support ❖ Built-in reflection free, faster startup, smaller JAR, reduced memory. ❖ Hibernate Validation: full Bean Validation API compliance. AOP: Aspect-Oriented Programing ❖ Compile-time, reflection free. HTTP Client ❖ Micronaut includes an HTTP client that has both a low-level API and a higher-level AOP-driven API.
