springboot▌

Comprehensive best practices guide for building production-ready Spring Boot applications. \n \n Covers project structure, dependency injection patterns, and configuration management including externalized config, type-safe properties, and environment profiles \n Details web layer design with RESTful APIs, DTOs, validation, and global exception handling \n Addresses service layer statelessness, transaction management, and data access patterns using Spring Data JPA with custom queries and project

Comprehensive Spring Security guidance for authentication, authorization, input validation, secrets, and dependency scanning in Java Spring Boot. \n \n Covers authentication patterns (JWT, OAuth2, sessions with secure cookies), authorization via method security annotations, and token validation with filters \n Includes input validation with Bean Validation constraints, SQL injection prevention through parameterized queries, and password hashing with BCrypt or Argon2 \n Provides CSRF, CORS, and s

Automated verification pipeline for Spring Boot projects: build, static analysis, tests with coverage, security scans, and diff review. \n \n Runs six sequential phases: Maven/Gradle build, static analysis (SpotBugs, PMD, Checkstyle), unit and integration tests with JaCoCo coverage reporting, dependency CVE scanning, optional code formatting, and git diff review \n Supports both Maven and Gradle with parallel build acceleration ( -T 4 flag) and includes example test patterns for unit tests, Test

Test-driven development framework for Spring Boot with JUnit 5, Mockito, MockMvc, Testcontainers, and JaCoCo enforcement. \n \n Covers unit tests (Mockito), web layer tests (MockMvc), integration tests (SpringBootTest), and persistence tests (DataJpaTest) with concrete examples \n Integrates Testcontainers for production-mirroring Postgres/Redis databases and JaCoCo for enforcing 80%+ code coverage \n Emphasizes Arrange-Act-Assert patterns, AssertJ assertions, and test data builders for maintain

Spring Boot development patterns and idioms tailored for Kotlin applications. \n \n Use primary constructors for dependency injection, data class for DTOs, and the kotlin-jpa plugin to automatically open entity classes without boilerplate. \n Organize code by feature/domain rather than layer; leverage Kotlin's null-safety to clearly define optional vs. required entity fields. \n Apply @ConfigurationProperties with data class for type-safe, immutable configuration; use application.yml and Spring

Spring Boot patterns for REST APIs, layered services, data access, caching, and async processing. \n \n Covers controller, service, and repository layers with Spring MVC/WebFlux, Spring Data JPA queries, and transactional boundaries \n Includes DTOs with validation, centralized exception handling via @ControllerAdvice , and RFC 7807 error responses \n Provides caching strategies with @Cacheable and @CacheEvict , async processing with @Async , and structured logging via SLF4J \n Demonstrates requ
