类 JsonUtil

java.lang.Object

io.github.a2ap.core.util.JsonUtil

public final class JsonUtil
extends Object

Utility class for JSON serialization and deserialization operations using Jackson. This class provides a centralized, thread-safe JSON processing facility with pre-configured ObjectMapper settings optimized for the A2A protocol. It handles common JSON operations including object serialization, deserialization with type safety, and JSON validation. Key features: - Ignores unknown properties during deserialization for backward compatibility - Supports Java 8 time types through JavaTimeModule - Provides null-safe operations with proper error handling - Includes JSON string validation utilities All methods are static and thread-safe, making this class suitable for concurrent usage across the A2A framework.
