An online service experienced frequent Full GC due to a ThreadLocal memory leak in a thread‑pool scenario; the article walks through GC log analysis, heap dump inspection, root‑cause discovery in ThreadFactory logic, and presents a robust fix using Spring’s TaskDecorator to ensure proper cleanup.
This article explains four techniques—manual setting, TaskDecorator, InheritableThreadLocal, and TransmittableThreadLocal—for propagating context such as user information from a parent thread to child threads in Spring Boot asynchronous execution, providing code examples and recommendations.
This article introduces four methods—manual setting, TaskDecorator, InheritableThreadLocal, and TransmittableThreadLocal—to propagate contextual data such as user information from a parent thread to child threads in Spring Boot asynchronous execution, providing code examples and practical recommendations.
This article explains four techniques—including manual setting, TaskDecorator, InheritableThreadLocal, and TransmittableThreadLocal—to reliably transfer user context and other thread‑local data from parent to child threads in Spring Boot asynchronous execution, with complete code samples and best‑practice recommendations.
This article explains how to configure Spring's thread pool, when thread‑context copying is needed, and how to implement a TaskDecorator to propagate execution context such as authentication or tracing information across asynchronous tasks.
