Full-stack Java development with Vue 2/3 front-end suite; hands-on examples and source code analysis for Spring, Spring Boot 2/3, and Spring Cloud.
This tutorial demonstrates how LiteFlow v2.16+ integrates AI agents as native components, enabling developers to orchestrate LLMs like DeepSeek, Qwen, and OpenAI models using familiar LiteFlow operators (THEN, WHEN, IF) within Spring Boot applications.
This article explains why gateway-only JWT validation is insufficient in zero-trust microservices, detailing Token Relay and Token Exchange patterns with Spring Boot 3.5 code examples for secure service-to-service authentication and authorization.
This article analyzes three critical @Transactional pitfalls in Spring Boot 3.5.0: deadlocks from inconsistent lock ordering during concurrent transfers, long transactions holding row locks during external RPC calls causing blocking and inconsistency, and nested transaction propagation causing unexpected rollbacks despite try-catch. Solutions include consistent lock ordering, transaction splitting, and using REQUIRES_NEW or programmatic transactions.
This article details six advanced Git commands—git switch, git restore, git stash push -m, git reflog, git add -p, and git bisect—that senior developers rely on for precise branch management, commit recovery, partial staging, and binary-search debugging, with practical examples and workflow comparisons.
This article demonstrates how to build one Spring Boot 3.5.0 REST endpoint that automatically returns different JSON fields for desktop, mobile, tablet, and unknown clients by combining classpath scanning, a custom ResponseBodyAdvice, Jackson @JsonFilter, and YAUAA user-agent parsing.
This tutorial demonstrates how to use ArchUnit to automatically enforce architectural constraints in Spring Boot projects, covering package structure validation, layered architecture protection, cycle detection between modules, and blocking problematic dependencies like BigDecimal(double) constructor through automated tests.
This article demonstrates four Spring Boot patterns to replace inefficient polling with real-time server push: STOMP over WebSocket for bidirectional updates, user-specific private channels, SSE with WebFlux for unidirectional streams, and Debezium CDC for database-level change capture — each with working code and configuration details.
This article presents six optimization strategies for handling oversized batch request bodies in Spring Boot, covering network compression with GZIP, Protobuf adoption, streaming JSON parsing with Jackson JsonParser, early validation layers, asynchronous processing via Kafka, and request chunking to reduce memory pressure and improve throughput.
This tutorial demonstrates building a graph-based workflow for AI agents using Spring AI Alibaba, covering state management, node implementation, conditional edges, and a practical excuse-upgrade example with LLM-driven nodes and dynamic routing based on believability scores.
JJTemplate compiles JSON-compatible templates into optimized ASTs for fast rendering, preserving type fidelity and offering conditional insertion, spread, pipes, ternary, safe access, and namespaced functions.
