Pre-Pull Request Audit Report (Issue #51: "Add support for classes annotated with @webfilter")

1. Functional Completeness Verification

• Full Module Test Execution: Executed .\mvnw.cmd test -pl components/sbm-recipes-jee-to-boot,applications/spring-shell -DfailIfNoSpecifiedTests=false
  • sbm-recipes-jee-to-boot: SUCCESS (All unit tests passed including MigrateAnnotatedServletRecipeTest)
  • spring-shell: SUCCESS (26 tests run, 0 failures, 0 errors, 3 skipped docker-dependent tests)
• Integration Test Confirmation: Executed shouldMigrateWebFilter in MigrateAnnotatedServletsIntegrationTest.
  • Confirmed that scanning a project containing @WebFilter correctly resolves migrate-annotated-servlets as an applicable recipe.
  • Confirmed that applying the recipe adds @ServletComponentScan alongside @SpringBootApplication.

2. Code Quality & Standards Audit

• Leftover Debug Statements / Unused Code: Checked all modified and newly created files. No leftover debug logs or commented-out code exist.
• Naming Conventions:
  • Mock class TheFilter.java follows the identical naming convention and package structure as TheServlet.java.
  • Integration test method shouldMigrateWebFilter follows standard JUnit 5 method naming conventions used across the project.
• Formatting & Recipe Definition:
  • migrate-annotated-servlets.yaml updated description to explicitly mention both servlets and filters.
  • Condition configured cleanly with org.springframework.sbm.java.migration.conditions.HasImportStartingWith (value: javax.servlet.annotation).

3. Git Hygiene Check

• Files Modified/Created (Strict Scope):
  1. [NEW] TheFilter.java
  2. [MODIFY] migrate-annotated-servlets.yaml
  3. [MODIFY] MigrateAnnotatedServletsIntegrationTest.java
