SPIT is an open-source collection of Bash scripts designed to inspect and analyze Spring Boot codebases. It assists developers in identifying code smells, unused configurations, dependency issues, and runtime risks within modern Java microservices build with Spring Boot. Each script in the toolkit focuses on a specific inspection area, allowing for modular usage and seamless integration into automation workflows.
| Script | Description |
|---|---|
spit_caching_usage.sh |
Detects usage of caching annotations and reports cache-related configuration. |
spit_circuit_breakers.sh |
Scans for circuit breaker usage like Resilience4j or Hystrix and extracts fallback mechanisms. |
spit_dead_weight.sh |
Finds unused classes, packages, and configuration files (aka "dead weight"). |
spit_dependency_updates.sh |
Checks for outdated dependencies via build files like pom.xml or build.gradle. |
spit_external_calls.sh |
Maps external HTTP and messaging system calls, including APIs and queues. |
spit_format_check.sh |
Checks code formatting using tools like spotless, google-java-format, or custom linters. |
spit_test_analysis.sh |
Analyzes test coverage, test structure, and identifies flaky or long-running tests. |
spit_unused_dependencies.sh |
Identifies unused Maven or Gradle dependencies, reducing build bloat. |
