This article walks through Spring Boot's bean creation pipeline—from the initial getBean call through doGetBean, the three‑level singleton cache, and the detailed steps of createBean, populateBean, and initializeBean—explaining how circular dependencies are safely resolved and where AOP proxies are generated.
This article breaks down Spring Boot's core refresh() method into twelve detailed steps, explaining how the IoC container prepares, configures, and starts up—including bean factory preparation, post‑processor registration, singleton instantiation, and final event publishing—providing interview‑ready insights and code illustrations.
This article explores the complete execution flow of Spring Boot’s auto‑configuration, detailing the role of @EnableAutoConfiguration, the AutoConfigurationImportSelector hierarchy, how candidate configurations are loaded from spring.factories, filtered by conditions, and how to create custom starters, with interview‑style Q&A.
This article dissects the @SpringBootApplication annotation, explaining how it combines @SpringBootConfiguration, @EnableAutoConfiguration, and @ComponentScan, and walks through the auto‑configuration mechanism, conditional annotations, and common interview questions with concrete code examples.
This article dissects the Spring Boot startup sequence step by step, showing how a minimal @SpringBootApplication triggers listeners, type deduction, auto‑configuration loading, environment preparation, IOC container creation, bean refresh, and embedded Tomcat launch, with interview‑ready explanations.
This article reviews the entire Spring Cloud microservices series, presents a full technology stack diagram, outlines production‑grade best practices for service decomposition, configuration, remote calls, rate limiting, databases, logging and monitoring, lists common pitfalls, offers performance‑tuning tips, discusses the pros and cons of microservices, and points to future directions such as service mesh, serverless and cloud‑native adoption.
This article explains why traditional deployment is problematic, then walks through building Docker images, composing services with Docker‑Compose, deploying to a Kubernetes cluster, setting up CI/CD pipelines, and addressing common pitfalls such as slow starts and service discovery failures.
The article outlines how to create a functional food‑delivery system for a graduation project by focusing on a core transaction loop, detailing user, merchant, and admin modules, and explaining why the rider side is intentionally limited to keep the project manageable.
This article explains why distributed transactions are essential in microservice architectures, introduces Alibaba's open‑source Seata solution, compares its AT, TCC and Saga modes, shows step‑by‑step Docker deployment, provides full Spring Cloud code examples, and lists common pitfalls and debugging tips.
This article explains why distributed tracing is essential for Spring Cloud microservices, introduces SkyWalking’s core concepts, compares it with other tracing tools, shows how to deploy SkyWalking via Docker Compose, integrate the Java agent, and use the UI to analyze performance, errors, and alerts.
