What is spring-mvc-to-boot-migrator?

A migration tool for moving Spring MVC applications to Spring Boot while preserving their existing behaviour. Spring MVC and Spring Boot are Java web frameworks, with Boot providing a more convention-based project setup.

Use it to migrate Maven or Gradle Spring MVC projects, convert XML configuration, update application code and tests, and produce a migration summary.

It reduces the manual work involved in changing build files, annotations, configuration, and tests during a framework upgrade.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00101	$0.02026
Opus 5	$0.00051	$0.01013

Security

Grade A, and why

spring-mvc-to-boot-migrator scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/migrate_annotations.py, scripts/migrate_build.py, scripts/migrate_config.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Spring MVC to Spring Boot Migrator

Overview

This skill automatically migrates Spring MVC applications to Spring Boot, transforming build configuration, annotations, XML configuration, controllers, and tests while preserving existing functionality. It handles Maven and Gradle projects, creates incremental git commits, and generates detailed migration summaries.

Quick Start

Basic Usage

# Navigate to your Spring MVC project
cd /path/to/spring-mvc-project

# Run migration (auto-detects Maven or Gradle)
python scripts/migrate.py .

# Or specify build tool explicitly
python scripts/migrate.py . --build-tool maven

The migration process will:

Create a migration branch
Analyze your codebase
Update build configuration
Migrate annotations
Convert configuration files
Update tests
Generate a summary report

Example Migration

# Migrate Spring MVC project
python scripts/migrate.py /path/to/project

# Output:
# ✓ Detected build tool: maven
# ✓ Detected Spring version: 5.3.20
# ✓ Created migration branch: migrate-spring-mvc-to-boot
# ✓ Analyzing codebase...
# ✓ Found 8 controllers
# ✓ Found 12 services
# ✓ Found 15 test files
# ✓ Migrating build configuration...
# ✓ Migrating annotations...
# ✓ Migrating configuration...
# ✓ Migrating tests...
# ✓ Migration completed successfully!

Supported Migration Paths

Spring MVC → Spring Boot

What gets migrated:

Build Configuration
- Maven: Add Spring Boot parent, update dependencies, add Spring Boot plugin
- Gradle: Add Spring Boot plugin, update dependencies
Annotations
- @Controller + @ResponseBody → @RestController
- @RequestMapping(method = RequestMethod.GET) → @GetMapping
- Similar for @PostMapping, @PutMapping, @DeleteMapping
- Update imports from javax.* to jakarta.*
Configuration
- XML configuration → Java configuration + application.properties
- web.xml → Spring Boot auto-configuration
- Create Spring Boot main application class

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
