Spring Boot Export Data to Excel with Apache POI Example

Learn to code Export to Excel function for an existing Spring Boot application using Apache POI library. The export feature allows the user to download data from database as Microsoft Excel document.

I will implement export Excel for a Spring Boot project that uses Spring Data JPA, Hibernate, Thymeleaf and MySQL. Exporting a list of users to Microsoft Excel xslx document.
You will also learn how to generate Excel file name based on current date time, and how to format cells in the Excel file.

- Technologies: Spring Boot + Spring Data JPA + Hibernate + Thymeleaf
MySQL JDBC driver

- Software programs: Java Development Kit (JDK), Spring Tool Suite IDE, MySQL database server and MyQL Workbench tool

For exporting data to other file formats, check these videos:

Hi anh, đối với chức năng export file Excel này.

Hiện tại theo hiểu biết của em thì sẽ có 2 giải pháp như sau:

- 1) Dùng thư viện Apache Poi của Java. Export trực tiếp ở Spring Boot Back End (REST API)
- 2) Sau khi call API để lấy data từ BE thì dùng 1 thư viện về Excel bất kì của Javascipt (ExcelJS, ….) export 1 file excel.
Anh cho em hỏi giải pháp nào ổn hơn ạ và trong thực tế thì cái nào được dùng nhiều hơn, ưu tiên hơn ạ?.Nếu được thì cho em xin ưu/nhược điểm của 2 giải pháp trên với ạ.Cảm ơn anh.

Great video! I have one question, if I want to use this to multiple pages and multiple db tables inside same project, do I need to create for every table new ExcelExport class, or there is a way to do it all inside one?

[manhkm]

If I had an excel file.
There are fields marked with the characters: ${value}

I want to read from that excel file and write data of those fields, how will I do with ApachePOI. Hope to receive a reply from you soon.
