Creating SpringBoot RestAPIs to upload and download multiple CSV files to databases: MySQL and PostgreSQL is one of the most common question in the development world. Going through the tutorial post”SpringBoot Upload Download Multiple CSV files to MySQL/PostgreSQL”, I explain details how to do it by step to step with coding and give you 100% running source code. What we will do?
– I draw an overview diagram architecture of SpringBoot RestAPI Upload CSV Files.
– I use Spring Web to development Spring RestApis.
– I use ApacheCommon or Open CSV libraries to parse and read CSV files.
– I use SpringJPA to save data from CSV files to MySQL and PostgreSQL.
– I implement a SpringBoot Global Exception Handler when uploading with a very big files and fail.
– I use Ajax and Bootstrap to implement a frontend client to upload/download CSV files.
