Improve developer experience with Spring Interface Clients Spring I/O 2024

Improve developer experience with Spring Interface Clients Spring I/O 2024

Spring now allows you to easily create elegant, highly readable, interface-based HTTP and RSocket clients. In this session we will discuss how developers can best use the clients in their applications to make HTTP and RSocket communication seamless.

During the presentation, we will go over various popular use-cases, but we will also discuss more complex scenarios, including how to best handle errors, override preset elements in individual requests, work with URIs, or pass attributes to underlying filter functions. We will show how to set up Spring Interface Clients with different underlying HTTP clients and how to easily integrate them with Spring Cloud LoadBalancer. Last but not least, we will take a peek into auto-configurations for Interface Clients.
