In my journey with Java and Spring Boot, I’ve found the doFilter() method in filters to be an essential tool for handling requests and responses. Let me share some insights!
Key Points:
- Filters can modify both the request and response objects as they pass through the filter chain. 🌀 - doFilter() takes three parameters: - ServletRequest: The incoming request data 📝 - ServletResponse: The response data being sent back - FilterChain: Used to invoke the next filter in the chain 🔗
Example Code:
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { // Pre-processing logic System.out.println("Before the request is processed");
// Continue the filter chain chain.doFilter(request, response);
// Post-processing logic System.out.println("After the request is processed"); }
Using filters effectively allows you to centralize logic like logging or authentication without cluttering your controllers. Happy coding! 🚀

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
Export WhatsApp stickers to Telegram on iPhone
You can’t. What you can do, though, is use WhatsApp’s and Telegram’s web platforms to transfer stickers. It’s easy, but might take a while.Open WhatsApp in your browser, find a sticker you like in a chat, and right-click on it to save it as an image. The file won’t be a picture, though—it’s a webpage and will have a .webp extension. Don’t be scared, this is the way. Repeat this step to save as many stickers as you want.Then, open Telegram in your browser and go into your Saved messages chat. Just as you’d share a file with a friend, click the Share file button on the bottom left of the chat window (it looks like a dog-eared paper), and select the .webp files you downloaded. Click Open and you’ll see your stickers in your Saved messages chat. This is now your sticker depository. To use them, forward them as you would a message from one chat to the other: by clicking or long-pressing on the sticker, and then choosing Forward.
