Hi, Spring fans! This week, Josh Long (@starbuxman) talks to transformational leader, my old boss, legendary technologist, and friend Patrick Chanezon (@chanezon).

Starting from version 3.1.0 as part of the Spring Cloud 2021.0.0 (aka Jubilee) release train, Spring Cloud Gateway included support for gRPC and HTTP/2.

We will introduce the basic concepts behind gRPC and how to configure it with two examples:

• One that showcases how Spring Cloud Gateway can transparently re-route gRPC traffic without needing to know the proto definition and without having to modify our existing gRPC servers.

• Another that showcases how we can create a custom filter in Spring Cloud Gateway to transform a JSON payload to a gRPC message.

Spring Cloud 2021.0.0 is finally out and with it you have Spring Cloud Function 3.2

While the full list of features, enhancements and bug fixes is available here, I’d like to call out few of them in this post and provide some details.

gRPC Support

Spring Message

Given the wide adaption of Spring Messaging, one way of benefiting from gRPC support is by embracing Spring's Message. Spring Cloud Function provides GrpcSpringMessage schema modeled after Spring's Message. It is internally converted to Spring Message to benefit from all of the existing support for Spring Messaging…
