    Spring WebClient is a reactive web client introduced in Spring 5, designed to replace the traditional RestTemplate. It is part of the Spring Web Reactive module and provides a non-blocking, reactive solution for making HTTP requests. WebClient supports both synchronous and asynchronous operations, making it suitable for applications running on both Reactive and Servlet stacks.

    Creating a WebClient Instance

    There are several ways to create a WebClient instance:

    • Default Settings:

    WebClient client = WebClient.create();
    Copied!

    • With Base URI:

    WebClient client = WebClient.create("http://localhost:8080");
    Copied!

    • Custom Configuration:

    WebClient client = WebClient.builder()
    .baseUrl("http://localhost:8080")
    .defaultCookie("cookieKey", "cookieValue")
    .defaultHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
    .defaultUriVariables(Collections.singletonMap("url", "http://localhost:8080"))
    .build();
    Copied!
