Spring Boot Verify

Verify Spring Boot 4.x projects for correct dependencies, configuration, and migration readiness. Use when analyzing pom.xml, build.gradle, application.yml, discussing Spring Boot project setup, dependency versions, configuration validation, version compatibility, migration to Spring Boot 4, deprecated dependencies, or when user mentions "verify project", "check dependencies", "upgrade Spring Boot", "migration readiness", "Jackson 3", "@MockBean deprecated", or "Spring Security 7".

Spring Boot 4.x Project Verification

Analyzes Spring Boot projects for dependency compatibility, configuration correctness, and migration readiness.

Verification Workflow

Detect Build System → Find pom.xml or build.gradle, extract Spring Boot version
Analyze Dependencies → Check versions, find deprecated libraries, validate compatibility
Validate Configuration → Check application.yml/properties, security config, actuator settings
Generate Report → Structured markdown with severity levels and remediation code
Lookup Docs → Use Exa MCP to fetch latest Spring Boot 4.x documentation when needed

Dependency Quick Reference

Check	Severity	Action
Spring Boot version < 4.0	CRITICAL	Upgrade to 4.0.x
Jackson 2.x (`com.fasterxml`)	CRITICAL	Migrate to Jackson 3 (`tools.jackson`)
`@MockBean` in tests	ERROR	Replace with `@MockitoBean`
Undertow server	ERROR	Switch to Tomcat or Jetty
Java version < 17	ERROR	Minimum Java 17 required
`spring-boot-starter-web`	WARNING	Use `spring-boot-starter-webmvc`

Configuration Quick Reference

Check	Severity	Action
Security `and()` chaining	CRITICAL	Convert to Lambda DSL closures
`antMatchers()` usage	ERROR	Replace with `requestMatchers()`
`authorizeRequests()`	ERROR	Replace with `authorizeHttpRequests()`
All actuator endpoints exposed	WARNING	Limit to health, info, metrics
100% trace sampling	WARNING	Use 10% in production

Tools to Use

Glob → Find **/pom.xml, **/build.gradle*, **/application.{yml,properties}
Grep → Search for deprecated patterns (@MockBean, com.fasterxml, .and())
Read → Inspect build files and configuration
Exa MCP → Fetch latest Spring Boot 4.x docs: mcp__exa__web_search_exa

Output Format

Generate verification reports with this structure:

## Spring Boot 4.x Verification Report

### Summary
- **Project**: {name}
- **Boot Version**: {detected version}
- **Issues Found**: {n} Critical, {n} Errors, {n} Warnings

### Critical Issues / Errors / Warnings
[Issue details with code remediation]

Detailed References

Migration Guide: See MIGRATION_GUIDE.md for step-by-step migration from Boot 3.x to 4.0
Examples: See EXAMPLES.md for sample verification outputs
Troubleshooting: See TROUBLESHOOTING.md for detection issues
Dependencies: See references/dependencies.md for complete version matrix
Configuration: See references/configuration.md for validation rules

Critical Reminders

Check Spring Boot version first — Many issues are version-specific
Jackson 3 namespace change — com.fasterxml.jackson to tools.jackson
Security 7 Lambda DSL — and() method removed, closures required
Testing annotations changed — @MockBean to @MockitoBean
Use official docs — https://docs.spring.io/spring-boot/documentation.html
