雅加达 EE 11 以及雅加达 EE 12 前路

发布于 7 月 1 日

Jakarta EE 11 Overview: Now available, it's the start of a new era in enterprise Java, aligning with modern standards, simplifying the platform, and positioning for cloud-native dev. Jakarta EE 12 is also in the works.
Dependency and Foundation: Even if using other frameworks like Spring Boot, Quarkus, etc., Jakarta EE is the foundation. Jakarta EE 11 aligns with Java 17 or higher, enabling features like sealed classes, pattern matching, records, and virtual threads via Jakarta Concurrency.
Jakarta EE 11 Release Details:
- Trims deprecated APIs for a leaner platform focused on today's needs.
- Jakarta CDI becomes the core dependency, moving towards a consistent, type-safe model.
- Supports Java records not just as DTOs but as first-class citizens in the specification. Records work seamlessly with Jakarta Bean Validation.
- Expands record support to Jakarta Persistence, allowing defining embeddable engines.
- Jakarta Concurrency gets a refresh with Java 21's virtual threads, enabling asynchronous and parallel operations with minimal thread management overhead.
- Jakarta Data is added, providing a unified API for working with data across relational and NoSQL databases, reducing boilerplate and aligning with modern frameworks. It offers a flexible model based on repository interfaces and supports pagination.
Jakarta EE 12 Highlights: Jakarta MVC and Jakarta NoSQL are part of the Web Profile. Jakarta Query is introduced for object-based querying, unifying SQL, NoSQL, and Data APIs.
Overall Impact: Jakarta EE is shedding its legacy and embracing modern Java practices, making enterprise Java modern, relevant, and robust again, benefiting various developers.
