Background:
I am working in a Java environment using Spring Boot, where I often encounter scenarios where global variable state management is critical, especially within singleton services. I have been exploring the idea of using annotations to automate cleanup global variable after used.
Goal:
My objective is to streamline global variable management using annotations, enhancing code clarity and maintaining thread safety across singleton services.
Proposed Solution:
I propose creating a custom annotation, let’s call it @CleanAfterUse, that leverages ThreadLocal under-the-hood. This annotation would handle initialization, management, and cleanup of thread-local state automatically, reducing boilerplate code and potential errors.
Questions:
What are the best practices for implementing annotations in Java to manage ThreadLocal variables effectively?
Are there alternative approaches or frameworks within the Java ecosystem that could achieve similar thread-local state management goals?
