This article explains how to use LangGraph's checkpoint and memory features together with a state‑machine router to build a chatbot that retains full conversation history, compresses long contexts, and dynamically switches between chat and task modes across multiple turns.
This tutorial shows how to replace bulky if‑else or switch logic with Spring Statemachine in a Spring Boot application, covering dependency setup, state and event enums, machine configuration, persistence, service implementation, controller endpoints, and advanced conditional transitions for loan processing.
This article provides an in‑depth technical analysis of Spring StateMachine's internal architecture, covering its class hierarchy, lifecycle start/stop mechanisms, pseudo‑state types, trigger processing, event dispatching, and persistence strategies, all illustrated with concrete code examples.
This article explains the fundamentals of finite state machines, introduces Spring Statemachine's features, and provides a step‑by‑step guide—including code samples, persistence options, testing, and AOP‑based error handling—to implement reliable order processing flows in Java backend applications.
This article introduces the fundamentals of finite‑state machines, explains the four core concepts of state, event, action and transition, and provides a step‑by‑step Spring Statemachine implementation with database schema, enum definitions, configuration, persistence options, testing, common pitfalls and an AOP‑based solution for reliable transaction handling.
This guide introduces Spring StateMachine, shows how to add the 1.2.0 release to a Spring Boot project, defines order‑related states and events, configures the state machine with annotations and Java code, and demonstrates a complete run that processes payment and receipt events.
