springboot

Inspiration

We found that many small internal systems lack a lightweight, stable backend service framework for rapid business iteration. Traditional development patterns involve repetitive configuration and boilerplate code, which slows down development efficiency. Therefore, we decided to build a backend service based on Spring Boot to provide a clean, reusable backend scaffold for common business scenarios.

What it does

This Spring Boot backend project provides core backend capabilities including user authentication, data CRUD interfaces, parameter validation, global exception handling, and simple permission control. It supports smooth interaction with front-end applications via RESTful APIs, and can be quickly extended to meet different business requirements such as data management and lightweight service scheduling.

How we built it

We chose Spring Boot as our core framework, paired with Spring MVC for request processing, MyBatis-Plus for database operations, and MySQL as the persistent storage. We also integrated Redis for cache acceleration. The project adopts a layered architecture including Controller, Service, Mapper and Entity. We used Maven for dependency management, and Postman for interface testing during development.

Challenges we ran into

One major challenge was global exception unification and custom return structure. It took us time to properly capture different types of exceptions without exposing internal error details. We also encountered cache consistency issues between Redis and MySQL. In addition, configuring cross-origin rules correctly to cooperate with the front end brought some debugging trouble.

Accomplishments that we're proud of

We successfully implemented a standardized REST API return format and a complete global exception handler. The permission verification module works stably, and the cache strategy effectively reduces database query pressure. The whole scaffold is decoupled well, so new business modules can be added with very little modification.

What we learned

We deepened our understanding of Spring Boot auto-configuration mechanism. We learned how to design reasonable interface specifications and handle exceptions gracefully. Besides, we gained practical experience in cache design, cross-domain processing and backend collaborative development norms.

What's next for springboot

In the future, we plan to add JWT token refresh mechanism and finer-grained RBAC permission management. We will introduce Swagger API documentation and integrate log aggregation. We also want to complete containerization with Docker and add simple unit tests to improve the stability of the service.
