Spring Boot FAQ: Top Questions

WebClient is a non-blocking, reactive web client introduced in Spring 5, recommended over RestTemplate for async and reactive applications.

📥 Example:

WebClient webClient = WebClient.create();
webClient.get()
         .uri("https://api.example.com/data")
         .retrieve()
         .bodyToMono(String.class)
         .subscribe(System.out::println);

🏆 Expected Output:

Asynchronous HTTP GET request and response printed.

🛠️ Use Cases:

• Consuming REST APIs reactively.
• Efficient handling of high-concurrency requests.
