What’s New in 1.0.0 Since 0.9.0

This section covers the changes made from version 0.9.0 to version 1.0.0.

  • Default stub factory now configurable via properties

  • Update to Spring Boot 4 / Spring Framework 7 and the corresponding Spring Portfolio updates (e.g. Spring Security 6)

  • JSpecify for nullability constraints

  • Java 25 support

What’s New in 0.9.0 Since 0.8.0

This section covers the changes made from version 0.8.0 to version 0.9.0.

  • Upgrade to Spring Boot 3.5.0.

  • 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.

What’s New in 0.6.0 Since 0.5.0

This section covers the changes made from version 0.5.0 to version 0.6.0.

Renamed Client Autowired Annotations

The old @GrpcClient annotation has been renamed to @ImportGrpcClients to better reflect its purpose, and to be more consistent with changes in the Spring framework. The customizer that is applied to generated gRPC clients is now a GrpcClientFactoryCustomizer - it’s main use is to modify the channel that a client is created with beyond the limits of what can be configured with spring.grpc.client.* properties.

What’s New in 0.5.0 Since 0.4.0

This section covers the changes made from version 0.4.0 to version 0.5.0.

Automatic Configuration of gRPC Clients

The @EnableGrpcClients and nested @GrpcClient annotations can now be used to automatically configure gRPC clients. Each @GrpcClient can be used to enumerate the stub types explicitly, or to scan a base package for stubs.

What’s New in 0.4.0 Since 0.3.0

This section covers the changes made from version 0.3.0 to version 0.4.0.

Fine-grained starter modules

The following fine-grained Spring Boot starter modules have been added:

  • spring-grpc-client-spring-boot-starter provides Netty gRPC client

  • spring-grpc-server-spring-boot-starter provides Netty gRPC server

  • spring-grpc-server-web-spring-boot-starter provides Servlet gRPC server

The current coarse-grained starter spring-grpc-spring-boot-starter still provides Netty gRPC server and client.
