Java Programming Models (Frameworks)

  • Best Java Frameworks Solutions The best Java Frameworks vendors are Apache Spark, Spring Boot, Oracle Application Development Framework (Oracle ADF), Jakarta EE, and Open Liberty. Apache is the top solution according to IT Central Station reviews and rankings. One reviewer writes: “Fast performance and has an easy initial setup”, and another reviewer writes: “Easy to use and is capable of processing large amounts of data”. The 2nd best product is Spring Boot. A user writes: “Very smooth implementation; excellent features for monitoring and tracking network calls “, and another reviewer writes: “Makes it difficult to support a specific functionality in a user-friendly manner, but simplifies application deployment”.

SpringBoot Tools

High-level abstractions/tools to run SpringBoot application on kubernetes without having to write 10,000 lines YAML. Tools that can automate the generation of Kubernetes manifests, so you concentrate only on building your business logic. Dekorate even supports annotations spring-like @KubernetesApplication(name="my-app") in your code, that generates your deployment manifest yml: - odo CLI tool - Dekorate Java library, has a Spring Boot support - JKube Maven plugin - Skaffold –generate-manifests - Spring Cloud Kubernetes - testcontainers-spring-boot ๐ŸŒŸ Container auto-configurations for spring-boot based integration tests. If you use Testcontainers with Spring Boot Hoja balanceรกndose en el viento you may be interested in the Playtika_Ltd Testcontainers library that provides auto-configurations for springboot based integration tests. It contains modules e.g. for kafka rabbitmq mongodb
