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! 🚀

Spiking bond yields driving sharp losses in tech stocks
A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year.
A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
Telegram auto-delete message, expiring invites, and more
elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
