StampedLock, introduced in Java 8, provides three lock modes—including an optimistic read that uses a 64‑bit stamp—to achieve higher throughput than ReentrantReadWriteLock in read‑heavy workloads, and the article explains its internal state, usage patterns, code examples, and important limitations.
This guide walks through ten practical techniques—startup lazy initialization, scoped component scanning, selective auto‑configuration, async processing, connection‑pool tuning, JPA batch settings, multi‑level caching, multi‑stage Docker builds, JVM container‑aware flags, Tomcat thread tuning, Resilience4j, observability stack, and TDD—to diagnose and eliminate performance bottlenecks in Spring Boot applications.
This tutorial shows how to combine the Strategy and Factory patterns in a Spring Boot payment system, separating algorithm definition, creation, and execution to achieve a flexible, extensible, and maintainable architecture that adheres to the Open/Closed principle.
This guide explains how to perform bidirectional conversion between JSON and CSV in Spring Boot using lightweight open‑source libraries such as Jackson, Apache Commons CSV or OpenCSV, as well as commercial APIs, covering serialization, deserialization, custom handling of nested objects, and provides complete code examples.
Field-level permission control provides fine-grained data access in Spring Boot applications, allowing read/write restrictions per object field; the article explains core concepts, compares annotation, AOP, serializer, and database approaches, and presents a complete implementation using Spring Boot 3.1, Java 17, Jackson, and Spring Security.
This article explains how Hibernate’s @Formula annotation lets Spring Boot developers define read‑only computed fields directly in entity classes, provides concrete code examples for single‑table calculations, sub‑queries, and conditional logic, and outlines compatibility and performance considerations.
This article compares four techniques—@JsonValue/@JsonCreator, @JsonFormat, custom serializers/deserializers, and a global @JsonComponent—to control how Java enums are serialized and deserialized by Jackson in Spring Boot, and outlines important pitfalls and version‑compatibility tips.
This guide explores ten advanced Spring Boot features—including conditional auto‑configuration, configuration‑property precedence, asynchronous execution, task scheduling, startup and JVM tuning, test context caching, Actuator monitoring, security setup, multi‑datasource configuration, custom starter creation, and cloud‑native deployment—to help developers move from users to masters of the framework.
This guide explains how to use Jackson's @JsonView annotation in Spring Boot to define view interfaces, annotate entity fields, configure controller methods, handle dynamic view selection, and apply best‑practice settings for secure and efficient JSON responses.
This article explains Spring’s data‑binding fundamentals, outlines the core DataBinder properties and control parameters, and demonstrates seven practical techniques—including simple POJO binding, @RequestParam, @RequestBody, nested objects, collection binding, HTTP‑header binding, and custom converters with @InitBinder—plus validation, error handling, performance advice, and troubleshooting tips for building robust Spring Boot applications.
