Create Spring Boot projects with Java 25 and Spring Boot 4. Use when user wants to create, build, scaffold, setup, or initialize a new Spring Boot application, microservice, REST API, or backend service; asks for project structure recommendations; mentions Java 25 or Spring Boot 4 features (RestTestClient, HTTP Service Clients, API versioning, JSpecify null-safety, modularization); needs architecture guidance (layered, package-by-module, modular monolith, tomato, DDD+hexagonal); or requests Spring Initializr setup. Also triggers on discussions about Spring Boot architecture patterns, Value Objects, CQRS, or domain-driven design.
Use this skill to create new Spring Boot 4 projects or define their structure before implementation. The skill adds value when the user needs an architecture decision, Spring Boot 4 feature selection, or the bundled templates in assets/.
assets/ instead of rewriting the same scaffolding from scratch.Collect the project constraints first:
Use this matrix as the default decision aid. If the choice is not obvious, read references/architecture-guide.md before proceeding.
| Pattern | Use when | Complexity |
|---------|----------|------------|
| layered | CRUD services, prototypes, MVPs | Low |
| package-by-module | 3-5 distinct features with moderate growth | Low-Medium |
| modular-monolith | Module boundaries matter and Spring Modulith is justified | Medium |
| tomato | Rich domain modeling, value objects, stronger type safety | Medium-High |
| ddd-hexagonal | Complex domains, CQRS, strong infrastructure isolation | High |
tomatois a value-object-heavy modular monolith: JPA entities embed VOs, validation lives in VO constructors, and Spring converters bind VOs at the request boundary. Seereferences/architecture-guide.mdfor the full definition.
Use Spring Initializr and capture the baseline:
Baseline dependencies for most projects:
Optional dependencies based on architecture or features:
Read references/spring-boot-4-features.md before selecting:
Use the bundled templates from assets/ and replace placeholders only after the package and module names are settled.
Every template uses {{TOKEN}} placeholders. Resolve all of them before applying — templates do not compile until every placeholder is replaced. The full set used across assets/:
| Placeholder | Replace with | Example |
|-------------|--------------|---------|
| {{PACKAGE}} | Base Java package | com.acme.shop |
| {{MODULE}} | Feature/module name (lowercase) | orders |
| {{NAME}} | Domain type name (PascalCase) | Order, ProductSKU |
| {{TYPE}} | Wrapped scalar type inside a value object | String, Long, BigDecimal |
| {{FIELD}} | Record field name (camelCase) | code, amount |
| {{TABLE_NAME}} | Database table name (used in JPA @Table) | orders |
| {{TABLE}} | Same meaning as {{TABLE_NAME}} — legacy variant kept only in flyway-migration.sql | orders |
| {{PROJECT_NAME}} | Project artifactId / docker prefix (used only in docker-compose.yml) | shop-api |
| {{name}} | HTTP service group identifier — not a lowercase variant of {{NAME}}. Appears only in commented @ImportHttpServices(group = "...") examples. | orders |
If a template uses a placeholder not listed here, treat it as a typo and confirm the intended value before applying.
