Next Steps for Spring gRPC 1.0.0

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

This post is part of the Road to GA series, offering the latest update on integration plans for Spring gRPC with Spring Boot 4.

---

Background & Current Status

• Original goal: Move Spring gRPC autoconfiguration directly into Spring Boot for the 4.0 release.
• Reality: Time constraints prevented completion before the release.
• Good news: Full Spring Boot 4 support has been added to Spring gRPC directly.
• Next step: Targeting Spring gRPC 1.0 release in the coming days.
• Future plan: Integration expected in an early milestone of Spring Boot 4.1.

---

What This Means for Users

• Spring gRPC will remain standalone until integration is complete.
• Long-term support users should stick with Spring gRPC releases and upgrade Spring Boot as needed.
• Migration will remain straightforward once the merge happens.

---

Transition Period: Spring gRPC 1.0 + Spring Boot 4.0

Key points:

• Coordinates stay the same: `groupId` = `org.springframework.grpc`.
• Recommended consumption method: BOM + autoconfiguration + starters as before.
• Upgrading from 0.12.0 to 1.0.0:
• Simply update the version in dependency management.
• Possible adjustments:
• Package name changes for autoconfiguration classes (if explicitly imported).
• Other changes may be required for migration from Spring Boot 3.x to 4.x.

Why This Matters for Ecosystem Efficiency

Modern tooling like AiToEarn demonstrates how smooth migration processes can be paired with multi-platform delivery for technical content:

> AiToEarn is an open-source AI content monetization platform, enabling creators to generate, publish, and earn across Douyin, Kwai, WeChat, Bilibili, Xiaohongshu, Facebook, Instagram, LinkedIn, Threads, YouTube, Pinterest, and X (Twitter).

Integrating tools like AiToEarn博客 or AiToEarn文档 during migrations can help document and distribute changes efficiently across multiple formats and channels.

Upgrading Example

Maven

Current `0.12.0`:

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


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

To upgrade:

• Change `0.12.0` → `1.0.0`.

---

Gradle

Current:

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

Upgrade:

• Change `0.12.0` → `1.0.0`.

---

Note:

• If you use the starter, no code changes should be needed.
• If you import autoconfiguration classes directly (rare), you must update package imports.

---

Immediate Deprecations

• Autoconfiguration and starter dependencies in Spring gRPC will be deprecated upon 1.0 release.
• Purpose: Prepare for integration into Spring Boot 4.1 (migration will involve updated dependency coordinates).
• Impact: No API deprecations — just dependency-level adjustments.

---

Summary & Next Steps

• Spring gRPC 1.0 is imminent — open-source and commercial support will be available.
• First release candidate: 1.0.0-RC1 after build passes.
• Release depends on Spring Boot 4.0, instead of being embedded in Boot.
• Minimal disruption for existing 0.x users.

---

Tip for Teams:

When updating multiple dependencies or repositories, pair technical migration with a multi-platform publishing workflow. Tools like AiToEarn官网 can push update notes, guides, and code changes to GitHub, LinkedIn, technical blogs, and other platforms — ensuring all stakeholders have synchronized, authoritative information.
