In a well-designed microservice system, exception and success classification must be consistent, traceable, and informative. Below is a complete reference list organized by type and mapped to HTTP status codes. Each exception or success type reflects its purpose: successful operations (2xx), client errors (4xx), or server errors (5xx). ✅ 1. Success Response Types → HTTP […]

The Adventuretube backend is designed with a clear separation of exception types, handling responsibilities, and architectural patterns to support robust, scalable microservices. There are two primary layers of exception management in the system: 1. Checked Exceptions (Handled with try-catch) These are exceptions that represent recoverable or gracefully degradable failures, such as I/O problems, API call

In the AdventureTube backend microservices architecture, configuration management is handled through a collaboration between Spring Cloud Config Server and environment (.env) files. This setup ensures consistency, flexibility, and secure handling of configuration data across different stages of deployment. 🧩 Background of env.XXX File Design The original idea behind creating env.XXX files was for Docker-based environments,

1. Configuration in Microservice For MapStruct to function properly within a Spring Boot microservices architecture, both the parent and sub-module pom.xml files must be correctly configured: Parent pom.xml <dependencyManagement> <dependencies> <dependency> <groupId>org.mapstruct</groupId> <artifactId>mapstruct</artifactId> <version>1.5.5.Final</version> </dependency> </dependencies> </dependencyManagement> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.10.1</version> <configuration> <annotationProcessorPaths> <path> <groupId>org.mapstruct</groupId> <artifactId>mapstruct-processor</artifactId> <version>1.5.5.Final</version> </path> <path> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.30</version> </path>

1. Correct Design of Controller and Service Principle: Thin Controller, Fat Service Controllers should only handle HTTP concerns: routing, request/response formatting, and returning status codes. Services should encapsulate business logic, including all validations and error throwing. Why This Matters 1. Separation of Concerns Layer Responsibility Controller Handle HTTP interface Service Contain domain logic and validation
