# @codemod/spring-7-api-config-migration Conservative Spring Framework 7 Java migration codemod for Java source under `src/main/java/**` and `src/test/java/**`. It applies deterministic AST-based rewrites for exact-safe Spring 7 baseline upgrades and avoids compatibility rewrites that require symbol resolution or project-specific policy. ## What It Rewrites - `WebMvcConfigurerAdapter`, `AsyncConfigurerSupport`, `SchedulingConfigurerSupport`, and `WebSocketMessageBrokerConfigurerAdapter` superclass usage to direct interface implementation. - Redundant single-constructor `@Autowired` annotations. - Spring `@Required` annotations. - Obsolete `@ConstructorBinding` markers. - `javax.validation.*` imports to `jakarta.validation.*`. - `LocalVariableTableParameterNameDiscoverer` to `StandardReflectionParameterNameDiscoverer` for imported or fully-qualified type references. - Simple `PropertySourcesPlaceholderConfigurer` bean methods that only return a new default instance from an annotation-based `@Configuration` class. - Exact Spring-version compatibility branches using `SpringVersion.getVersion()` and allowlisted `ClassUtils.isPresent(...)` checks whose outcome is dead on a Spring 7 baseline. ## Preserve Cases - User-defined types that only share a Spring adapter simple name. - Constructors where `@Autowired` is still required because multiple constructors exist. - `PropertySourcesPlaceholderConfigurer` beans with custom settings or initialization logic. - Optional-library probes unrelated to Spring baseline compatibility. - Production `SocketUtils` replacement, field-to-constructor injection, and other policy-sensitive rewrites from the broader spec. ## Run ```bash codemod workflow run -w workflow.yaml --target /path/to/repo ``` ## Development ```bash pnpm test pnpm check-types pnpm dlx codemod@latest workflow validate -w . ``` ## License MIT
