This article explores six practical AI Agent design patterns—ReAct, Tool Use, Reflection, Planning, Multi‑Agent, and Human‑in‑the‑Loop—detailing their principles, Java Spring AI implementations, advantages, drawbacks, and suitable scenarios, and provides guidance on selecting and combining them for robust AI applications.
This article compares Spring AI Alibaba and AgentScope-Java, examining their distinct design philosophies—graph‑based workflow versus agentic autonomy—core architectures, key capabilities, code examples, and practical selection guidance, while also highlighting the emerging trend of merging both approaches for optimal Java AI development.
This article provides an in‑depth analysis of Spring AI Alibaba, comparing it with Spring AI, detailing its four‑layer architecture, GraphCore workflow engine, AgentFramework, enterprise‑grade MCP integration, code examples, pros and cons, suitable scenarios, and future roadmap for Java developers building AI applications.
When a production error generates a massive log file, this guide teaches backend engineers how to efficiently inspect and troubleshoot using Linux commands like tail, less, grep, sed, and awk, with concrete real‑world scenarios and exact command examples.
A Spring Boot channel service showed an unexpected 100 ms latency; by systematically checking network, using curl, and employing Arthas to trace Spring MVC and Tomcat internals, the author discovered a Tomcat‑embed bug that repeatedly loads Swagger‑UI JAR resources, which is resolved by upgrading Tomcat.
This article introduces a powerful, extensible Spring validation component built on SpEL that handles simple annotations, enum checks, multi‑field logic, and Spring Bean integration, providing step‑by‑step setup, usage examples, custom constraints, and performance considerations for Java backend developers.
This article explains how to import 1 billion 1 KB log records stored in HDFS/S3 into MySQL by analyzing single‑table limits, proposing sharding into multiple tables, choosing the right storage engine, using batch inserts, controlling concurrency, and ensuring ordered, reliable processing with Redis and Redisson.
When a Spring Boot application using @Scheduled is deployed on multiple servers, each instance triggers the same job, leading to duplicate processing; this article explains why the problem occurs, reviews simple single‑node and Redis lock approaches, and provides a step‑by‑step guide to integrate the ShedLock framework for reliable, annotation‑driven distributed locking.
This article explains how to replace static permission annotations in Spring Boot with flexible SpEL expressions, showing step‑by‑step how to create a @PreAuth annotation, an AOP aspect, an expression parser, and a utility class that evaluates role‑ and time‑based access rules at runtime.
JSONPath offers a concise, XPath‑like syntax for extracting data from complex JSON structures, and this guide shows how to integrate it into Spring Boot, compare FastJSON, Jackson, and Gson implementations, and provides practical code examples, advanced configurations, and selection advice for Java projects.
