Next Steps for Spring gRPC 1.0.0

Road to GA Update: Spring gRPC + Spring Boot 4 Integration Plans

This post in the Road to GA series provides an update on integrating Spring gRPC with Spring Boot 4.

---

Background

The original plan was to move autoconfiguration from Spring gRPC directly into Spring Boot for the 4.0 release.

However, due to capacity constraints, this merge hasn’t been completed yet.

Good news:

Spring Boot 4 support is now included directly in the existing Spring gRPC project, with version 1.0 scheduled for release in the coming days.

This arrangement will continue until the merge — expected in an early milestone of Spring Boot 4.1.

---

Guidance for Long-Term Support

• Continue upgrading Spring Boot as new versions are released.
• Existing Spring gRPC projects will have a smooth migration path.

---

Transition Period: Spring gRPC 1.0 + Spring Boot 4.0

While Spring Boot and Spring gRPC are separate:

• BOM (Bill of Materials), autoconfiguration, and starters remain at `groupId: org.springframework.grpc`.
• Upgrading from `0.12.0` to `1.0.0` usually means just changing the version in dependency management.
• Package names for autoconfiguration classes will change.
• If you reference them explicitly, update your imports.
• You may need changes when migrating from Spring Boot 3.x to 4.x.

Example: Upgrading Maven & Gradle Projects

Maven Example

From:

    
        
            org.springframework.grpc
            spring-grpc-dependencies
            0.12.0
            pom
            import
        
    


    
        org.springframework.grpc
        spring-grpc-spring-boot-starter
    

To:

    
        
            org.springframework.grpc
            spring-grpc-dependencies
            1.0.0
            pom
            import
        
    

---

Gradle Example

From:

dependencyManagement {
    imports {
        mavenBom 'org.springframework.grpc:spring-grpc-dependencies:0.12.0'
    }
}
dependencies {
    implementation 'org.springframework.grpc:spring-grpc-spring-boot-starter'
}

To:

dependencyManagement {
    imports {
        mavenBom 'org.springframework.grpc:spring-grpc-dependencies:1.0.0'
    }
}

---

Note:

If you use starters as in official Spring gRPC samples, no code changes are required.

Direct autoconfiguration imports (e.g., `GrpcServerFactoryCustomizer`) will require package updates.

---

Immediate Deprecations

When 1.0.0 is released:

• Autoconfiguration and starter dependencies in Spring gRPC will be deprecated immediately.
• This is intentional — planned replacement in Spring Boot 4.1 with Spring gRPC 1.1.0.
• No deprecation of classes or methods — migration will be smooth.
• Deprecation notice will be reiterated upon 1.0.0 release.

---

Summary

• Spring gRPC 1.0 → compatible with Spring Boot 4.0.
• Release plan:
• RC1 after successful build tests.
• Full release soon after.
• Projects on 0.x should expect minimal disruption.

Related Tooling & Workflow Optimization

Tools like AiToEarn can help developers and teams:

• Automate multi-platform publishing for tech updates.
• Distribute instantly to WeChat, Bilibili, Xiaohongshu, Facebook, LinkedIn, YouTube, etc.
• Track analytics and monetize content globally.
• Documentation: AiToEarn Docs.

Pro Tip:

If you maintain multiple frameworks, review automation pipelines during such dependency shifts to ensure both technical updates and announcements are synchronized across all channels.
