grails團隊的新框架：micronaut

體積更小，內存佔用更小，性能更優？同時支持java,groovy,kotlin三種編程語言。grails框架我用過，作過若干個項目，確實比較方便，腳手架快速生成頁面（固然結合ieda來使用），orm自動化管理，多種組合模式，代碼比較簡潔，寫一個對象的增刪改查，大概10幾鍾搞定（有在用的前端框架的前提下，默認的前端通常不適合真實業務使用）。

Micronaut

Micronaut is a modern, JVM-based, full stack microservices framework designed for building modular, easily testable microservice applications.

Micronaut is developed by the creators of the Grails framework and takes inspiration from lessons learnt over the years building real-world applications from monoliths to microservices using Spring, Spring Boot and Grails.

Micronaut aims to provide all the tools necessary to build microservice applications including:

• Dependency Injection and Inversion of Control (IoC)
• Sensible Defaults and Auto-Configuration
• Configuration and Configuration Sharing
• Service Discovery
• HTTP Routing
• HTTP Client with Client-Side Load Balancing

At the same time Micronaut aims to avoid the downsides of frameworks like Spring, Spring Boot and Grails by providing:

• Fast startup time
• Reduced memory footprint
• Minimal use of reflection
• Minimal use of proxies
• Easy Unit Testing
