About This Software
Spring REST provides multiple approaches to handle file downloads, including returning ResponseEntity with byte arrays, streaming files directly, or using ResourceHttpMessageConverter. The most efficient method depends on your specific use case, file size, and performance requirements. We'll explore each approach with practical examples, discuss error handling, and cover important considerations like security, caching, and progress tracking for large files.
