Spring’s team announced that RestTemplate will be deprecated in Spring Framework 7.0 and removed later, outlining its limitations and presenting the new RestClient as a modern, fluent alternative, while also recommending WebClient for reactive scenarios and offering migration strategies for existing projects.
Spring announced that RestTemplate will be deprecated in Spring Framework 7.0 and removed later, outlining a migration path to the newer RestClient for synchronous use and WebClient for reactive scenarios, while providing a timeline and practical guidance for developers.
Spring Framework 7 will deprecate RestTemplate, outlining a migration timeline, the shortcomings of the classic HTTP client, and introducing RestClient and WebClient as modern alternatives for synchronous and reactive applications, while providing guidance for both new and legacy projects.
This article compares Feign and Spring 6's @HttpExchange for remote service calls, walks through practical examples—including interface definition, proxy creation, various client options, testing, reactive returns, custom argument resolvers, and error handling—while providing complete code snippets for Spring Boot 3.4.2.
This article walks through Spring Boot 3.2.5 enhancements including multithreaded bean initialization, the new @Fallback annotation, handling duplicate bean names, RestClient.create(URI) usage, header binding to records, expanded task‑scheduler metadata, and a host of other backend improvements.
This article introduces Spring Boot's new RestClient, compares it with RestTemplate and WebClient, and provides detailed code examples for creating clients, performing GET/POST/PUT/DELETE requests, handling errors, customizing interceptors, and enabling load‑balanced service discovery.
Spring offers multiple HTTP clients—RestTemplate, WebClient, and the newer RestClient—each with distinct features, performance characteristics, and suitability for different scenarios, and this guide compares their core capabilities, advantages, drawbacks, and best-use cases to help developers select the optimal client for their projects.
This guide explains how to create and configure Spring Boot's RestClient, covering instance creation, request building, header and body handling, response retrieval, error processing, the exchange method, and available client request factories for robust synchronous HTTP communication.
This guide walks through Spring 6’s new capabilities—including Java 17 baseline, Jakarta namespace migration, HTTP interface proxies with @HttpExchange, WebClient integration via JDK HttpClient, internationalized ProblemDetail handling, the RestClient API, and executing asynchronous tasks on virtual threads—all demonstrated with concise code examples.
Spring 6 offers four powerful ways to perform remote HTTP calls—WebClient, RestTemplate, HTTP Interface, and RestClient—each with distinct APIs, configuration options, and usage patterns, and this guide walks through their setup, method signatures, request handling, and error management for Java developers.
The article explains how our driver‑passenger matching service migrated from load‑balanced Elasticsearch access to a direct RestClient, then automated node discovery using the built‑in Sniffer and SniffOnFailureListener, detailing its scheduling, request logic, and how this eliminates manual IP management while keeping the client in sync with cluster topology.
This guide explains how to use Spring 6.1's new RestClient for synchronous HTTP calls, covering setup, request building, response handling, data conversion, error processing, and advanced exchange methods with full code examples.
This guide walks you through Spring 6.1's new RestClient, covering project setup, global client creation, data retrieval, posting, deletion, error handling, and advanced exchange methods with clear code examples for modern Java backend development.
This article introduces Spring 6.1’s new synchronous RestClient, showing how to perform basic GET and POST requests, convert responses to objects, handle errors with onStatus, and use the advanced exchange method for custom request‑response processing, positioning RestClient as a modern replacement for RestTemplate.
