November 25, 2025 - Simply put, WebClient is an interface representing the main entry point for performing web requests. It was created as part of the Spring Web Reactive module and will be replacing the classic RestTemplate in these scenarios.

January 29, 2025 - To start using WebClient, you need to add the required dependencies to your pom.xml (if you’re using Maven): <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-webflux</artifactId> </dependency> </dependencies>

Spring WebFlux includes a client to perform HTTP requests. WebClient has a functional, fluent API based on Reactor (see Reactive Libraries) which enables declarative composition of asynchronous logic without the need to deal with threads or concurrency.

Compared to RestTemplate, this client has a more functional feel and is fully reactive. You can create your own client instance with the builder, WebClient.create(). See the relevant section on WebClient. Spring Boot creates and pre-configures such a builder for you.

July 23, 2025 - It is a part of spring-webflux library and also offers support for both synchronous and asynchronous operations. The DefaultWebClient class implements this WebClient interface. ... Add this dependency to the pom.xml file. <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-webflux</artifactId> </dependency>

A mutable builder for creating a WebClient.

July 25, 2024 - WebClient is a reactive client that provides an alternative to RestTemplate. It exposes a functional, fluent API and relies on non-blocking I/O which allows it to support high concurrency more efficiently than the RestTemplate.

March 29, 2023 - Spring boot WebClient is basically part of the reactive framework which was used to construct the non-blocking and reactive web-based application. WebClient is part of the spring MVC project, and it will allow communication with http servers; ...

December 25, 2024 - GZIP compression provides higher performance, while microservices carry large request payloads. Spring Boot's WebClient provides many features, such as connection pools, request timeouts, and retry policies, improving performance to a great extent.

Spring Boot is configuring that builder to share HTTP resources, reflect codecs setup in the same fashion as the server ones (see WebFlux HTTP codecs auto-configuration), and more. ... @Service public class MyService { private final WebClient webClient; public MyService(WebClient.Builder ...

May 25, 2021 - This can also use the standard HttpMessageConverter configuration registered in your Spring application, so message converters can be shared between your WebMVC or WebFlux server code and your WebClient instances. If you’re using Spring Boot, you can use the pre-configured WebClient.Builder instance to get this set up automatically.

April 10, 2024 - n the above code snippet, we inject the WebClient bean into the MyService class and use it to make an HTTP GET request to the specified URI. The response is then converted to a Mono<String> using the bodyToMono() method. Conclusion: By implementing a generic Web Client with ExchangeFilterFunction in Spring Boot, you can easily communicate with external APIs in a flexible and reusable manner.

September 14, 2023 - To use WebClient api, we must have the spring-boot-starter-webflux module imported into our Spring Boot project.

The following auto-configuration classes are from the spring-boot-webclient module: · ReactiveHttpServiceClientAutoConfiguration

This project shows how to use reactive client WebClient in a Spring Boot application.

November 22, 2024 - The Spring WebClient ships in the Webflux library. In order to use WebClient in a Spring Boot Project we need add dependency on WebFlux library.

December 8, 2024 - WebClient is a powerful, versatile, and modern HTTP client for Spring Boot applications, enabling developers to build efficient, reactive, and scalable systems. It is best suited for high-concurrency environments, real-time data processing, ...

June 9, 2025 - WebClient is Spring’s modern, reactive HTTP client. Supports non-blocking I/O and reactive streams (Mono, Flux). More scalable than blocking RestTemplate for high-load or streaming apps.
