This is a new blog post in the Road to GA series, this time updating everyone on the plans to integrate Spring gRPC with Spring Boot 4. The original plan was to move the autoconfiguration from Spring gRPC into Spring Boot in time for the 4.0 release. Unfortunately we haven't been able to find the time to merge that change, but the good news is that we have instead added support for Spring Boot 4 to the existing Spring gRPC project, and are planning a 1.0 release in the coming days. This arrangement will continue until the merge can finally happen, most likely in an early milestone of Spring…

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring gRPC 0.11.0 has been released and is now available from Maven Central. We are still planning to have a 1.0.0 release around the same time as Spring Boot 4.0.0.

The main changes in this release are bug fixes for 0.10.0. There is a small API change in the custom security adapter that extracts authentication data from an incoming request on the server. All users should upgrade as soon as possible.

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring gRPC 0.9.0 has been released and is now available from Maven Central. We are still planning to have a 1.0.0 release around the same time as Spring Boot 4.0.0.

The main changes in this release are

• Upgrade to Spring Boot 3.5.
• StubFactory contract changes: the "supports" method is now a static method (it is called before an instance is created).
• Removed GrpcClientFactoryCustomizer in favour of GrpcChannelBuilderCustomizer.
• Added ability to filter interceptors in in-process gRPC clients.
• Added ability to filter global interceptors and service definitions - easy to do for InProcessGrpcServer and possible to do for NettyGrpcServer by registering a customizer.

It's a few months since we had a blog about Spring gRPC that wasn't just a release announcement. This one marks the first release since the project was promoted from experimental to a full member of the Spring Portfolio. This doesn't change the way you consume the project, but it has some implications for support and symbolically for what the project now means to the portfolio.

The latest release is 0.8.0, and it has been available for a couple of weeks now in Maven Central. The main reason for that release was to bump the dependencies to their latest versions, bringing Spring gRPC up to version 4 of the protobuf-java libraries. The easiest way to get started is to download a project with "gRPC" checked on the Spring Initializr. There are separate "starters" for Spring Boot applications gRPC that want to be "servers" or "clients", or you can get both at once from the plain spring-grpc-spring-boot-starter…

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring gRPC 0.8.0 has been released and is now available from Maven Central. This is the first "non-experimental" release, signified by the project moving to its new repository location in the https://github.com/spring-projects organization. Support will be provided for the only current 0.x release, and the normal cycle of extended support will start with the 1.0.0 release (expected around the same time as Spring Boot 4.0.0).

The main change in this release was to upgrade Spring Boot and also the gRPC Java and…

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring gRPC 0.6.0 has been released and is now available from Maven Central.

The main change in this release was to rename the annotation for creating gRPC client beans to @ImportGrpcClients, harmonizing with the work on HTTP interface clients in Spring Framework. This release includes features, bug fixes, documentation improvements, and dependency upgrades. Thanks to all those who have contributed with issue reports and pull requests.

The experimental Spring gRPC project released its 0.3.0 version recently. Jars are available in Maven Central, and you can generate a new project with Spring gRPC at https://start.404ofchina.website. We recommend you do that if you are trying it out because there are some build plugins to configure and the generated project will have that all sorted out for you.

The new release has some updates to factory interfaces on the client side. Also there is now full support for autoconfiguration of client side interceptors, including the ones from Micrometer. On the server side we now support Spring Security…

A few Java libraries have shown up recently that use text templates, but compile to Java classes at build time. They can thus claim to some extent to be "reflection free". Together with potential benefits of runtime performance, they promise to be easy to use and integrate with GraalVM native image compilation, so they are quite interesting for people just getting started with that stack in Spring Boot 3.x. We take a look at a selection of libraries (JStachio, Rocker, JTE and ManTL) and how to get them running.

The source code for the samples is in GitHub and each template engine has its own…
