When building modern web applications, the ability to import data from external files like CSV into a database is a common requirement. However, this process often introduces various challenges that, if not handled properly, can result in corrupted data, system crashes, or security vulnerabilities. Understanding these pitfalls and designing robust error-handling mechanisms is crucial for developers working with Spring Boot. In this article, we’ll delve deep into the techniques to manage errors during CSV data import and explore the surrounding aspects, including validation, logging, and retry mechanisms, all with detailed code examples and explanations.
