Secure communications end-to-end for Spring Boot apps - in a Zero Trust environment

Hi, Spring fans! Today, we are excited to announce the general availability of all the features to secure communications end-to-end for Spring Boot apps – in a Zero Trust environment. You can secure communications end-to-end or terminate transport level security at any communication point for Spring Boot apps. You can also automate the provisioning and configuration for all the Azure resources needed for securing communications.

Implementing secure communications as part of your solution architecture can be…

Spring Cloud Gateway and gRPC

Engineering | Alberto C. Ríos | December 08, 2021 | ...

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 Function 3.2 is out!

Engineering | Oleg Zhurakousky | December 02, 2021 | ...

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

In addition to an already existing support for invoking function via AWS Lambda, RSocket, Spring Cloud Stream etc., Spring Cloud Function now allows you to invoke function via gRPC. Two ways to benefit from it.

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

This Week in Spring - November 30th, 2021

Engineering | Josh Long | November 30, 2021 | ...

Hi, Spring fans! Welcome to another installment of This Week in Spring! This last week's been nutty! Here in the US, we just celebrated the Thanksgiving holiday, and I am fat with turkey and pie, and lazy. But happy. I hope you're well fed and happy, too. Time's flying. (Also: can you believe we're a month away from the new year? I think there's like four or five weeks (and thus _This Week in Spring_s!) left in the year!)

We've got a ton of stuff to get into this week, so let's go:

Security Report for Spring AMQP (Spring for RabbitMQ)

Engineering | Gary Russell | November 29, 2021 | ...

The recently released versions of Spring AMQP (2.4.0, 2.3.12, 2.2.20) contain a fix for CVE-2021-22095, which can cause a potential OutOfMemoryError for very large messages.

Spring Boot version 2.6.0 and 2.5.7 will bring in the 2.4.0 and 2.3.12 versions of spring-amqp respectively. Users of Boot 2.4.x should override the spring-amqp and spring-rabbit versions to 2.3.12; users of Spring Boot 2.3.x should override the versions to 2.2.20.
