This is a new blog post in the Road to GA series, this time exploring the new capabilities of our HTTP clients. This is also a good time to reflect on the state of HTTP clients in Spring, so we will use this opportunity to explain an important announcement: we are officially deprecating RestTemplate.

Upcoming RestClient features

RestClient has been introduced in Spring Framework 6.1 and evolved in the 6.x line. In the upcoming 7.0 major version we are keeping up the pace with a round of new features.

API Versioning

Spring @Controller now supports the API Versioning concept to better implement different generations of your REST API within a single application. This feature is also supported on the client side, by using an ApiVersionInserter…

In this 3rd blog post of the Road to GA series that’s highlighting major features within the Spring portfolio for the next major versions to be released in November we’ll have a look at new features for HTTP service clients, which are a collaborative effort across several Spring projects.

Introduction

Spring Framework 6 introduced the ability to define an HTTP service through a Java interface with @HttpExchange-annotated methods. For example:

public interface MilestoneService {

    @GetExchange("/repos/{org}/{repo}/milestones")

That's right: an incredible new iteration of the JVM has just dropped and with it come a ton of features! Let's go through some of my favorites.

One nicety is the new Module import declarations - import all the packages in a given module with a new import variant. (Does not require importer be in a module). So now you could do: import module java.base; to get most of the core JDK types in your program in a single line…

The Model Context Protocol (MCP) standardizes how AI applications interact with external tools and resources. Spring joined the MCP ecosystem early as a key contributor, helping to develop and maintain the official MCP Java SDK that serves as the foundation for Java-based MCP implementations. Building on this contribution, Spring AI has embraced MCP with comprehensive support through dedicated Boot Starters and MCP Java Annotations, making it easier than ever to build sophisticated AI-powered applications that can seamlessly connect to external systems.

This blog introduces core MCP components and demonstrates building both MCP Servers and Clients using Spring AI, showcasing basic and advanced features. The complete source code is available at: MCP Weather Example…

In this 2nd blog post of the Road to GA series highlighting major features within the Spring portfolio for the next major versions to be released in November, I’m going to focus on the upcoming API Versioning support in Spring Framework 7.

Introduction

API versioning is a challenging topic. Most articles list various ways to do it, but offer no advice. When advice is offered, it ranges widely. For example, Roy Fielding advises against it. It is a common and widely used practice, and yet there is no standard or agreement on how to or whether to do it.

Furthermore, different applications have…
