Execute Synchronous Requests Using WebClient

Date: 2024-10-18

The Spring WebClient, though primarily used for asynchronous, non-blocking HTTP requests, can also perform synchronous calls using the block() method. This article details how WebClient compares to other Spring HTTP clients like RestTemplate and OkHttpClient, highlighting its flexibility. While synchronous requests are simpler for some use cases, the article emphasizes that asynchronous calls are generally more efficient for modern reactive systems due to improved scalability and resource utilization. The example shows a synchronous POST request using WebClient and discusses potential error handling. Choosing between synchronous and asynchronous depends on the application's needs; prioritizing asynchronous methods for performance in high-concurrency scenarios.
