发布于 9 月 16 日

Replatforming Challenge: Replatforming from Java 8 to newer Java versions is challenging due to compatibility issues and language spec changes. Spring Framework 6.2.10 requires Java 17 or higher, so migrating from Java 8 involves code modifications and testing.
Amazon Q Developer for App Modernization: It helps with application modernization. Steps for updating software using it include planning, drafting use cases, generating code, writing tests, scanning for vulnerabilities, performing remediation, migrating code, and troubleshooting.
Migrating to Java 21:
- Build Code: Use Amazon Q Developer's transformation feature in the IDE or handle dependency management. Set up environment, specify source and target versions, review changes, and confirm. Build and test the migrated application.
- Upgrade to Java 21: Currently supports up to Java 17; manual intervention needed for Java 21. Consider key considerations like SDK changes, security updates, removed APIs, and tools.
Advantages of Amazon Q Developer: Provides familiar security controls, available in multiple languages, connects with GitHub and IDEs, offers flexible pricing, handles large projects, integrates with AI tools, and is available in MS Teams and Slack.
Conclusion: AWS Amazon Q developer reduces manual effort, accelerates migration, ensures seamless transition, is scalable and fast, and supports multiple programming languages. It is helpful in migrating enterprise projects from Java 8 to Java 21, making the process more efficient.
