1.1.0

What's New

Trace/Request ID Propagation

New infrastructure for propagating trace and request IDs across HTTP and gRPC boundaries.

kit-java-web:

• RequestContext — ThreadLocal holder for trace/request ID
• RequestContextFilter — Servlet filter that extracts/generates trace+request IDs, stores in MDC, sets response headers
• ContextPropagation — Utilities to propagate context across async boundaries (wraps Runnable/Callable)

kit-java-grpc:

• ContextPropagationInterceptor — Server interceptor that extracts trace/request/user/tenant from metadata into gRPC Context + MDC
• ContextForwardingInterceptor — Client interceptor that forwards context values to outgoing calls

Behavior

• Extracts X-Trace-ID / X-Request-ID from incoming headers (HTTP) or metadata (gRPC)
• Generates UUIDv7 if absent
• Stores in SLF4J MDC (traceId, requestId) for log correlation
• Sets response headers automatically
• Cleans up ThreadLocal + MDC after request completes

Full usage examples in README.

1.0.3

Changes

• Add BaseResponse.success() and BaseResponse.success(data) static factory methods to avoid ambiguous constructor call with null
• Update README with new API usage

1.0.2

Breaking changes

• kit-java-core: remove deprecated UUIDUtils.v4String() and UUIDUtils.v7String(). Use UUIDUtils.v4().toString() / UUIDUtils.v7().toString() instead.

1.0.1

Changes

• kit-java-core: deprecate UUIDUtils.v4String() and UUIDUtils.v7String() — use v4() / v7() + toString() instead.
