This tutorial explains how to use Spring Boot's programmatic transaction management—including TransactionTemplate, TransactionCallback, and PlatformTransactionManager—with detailed code examples, configuration tips, and rollback handling to improve data consistency and performance.
This article explains how to execute two dependent tasks in parallel with CompletableFuture, why the usual @Transactional annotation fails in a multi‑threaded environment, and provides a programmatic transaction solution that copies Spring's transaction resources between threads to guarantee atomic commit or rollback across all parallel operations.
This article explains how using Spring's @Transactional annotation can unintentionally create long-running transactions, illustrated by a production incident where database connections were exhausted, and provides strategies such as method splitting, programmatic transactions, and proxy usage to avoid such pitfalls.
This article compares Spring's programmatic and declarative transaction management, explains how each works with code examples, outlines the benefits and limitations of declarative transactions—including granularity and failure scenarios—and argues why developers should consider programmatic transactions for clearer control and fewer hidden bugs.
