Modern full-stack development often requires a seamless integration of robust backend services and responsive frontend interfaces. This architecture leverages Spring Boot for the backend, Vue.js for the web interface, and Uni-app for cross-platform mobile support.

Core Technology Stack

• Spring Boot: Provides a streamlined environment for building production-ready applications. With feautres like auto-configuration and an embedded server, it significantly reduces boilerplate code and infrastructure setup time.
• Vue.js: A progressive framework utilizing a virtual DOM and reactive data-binding, enabling developers to build highly interactive and maintainable user interfaces.
• MyBatis-Plus: An efficient ORM enhancement for MyBatis that simplifies database interactions, provides built-in pagination, and includes a code generation tool to accelerate development.

Authentication Implementation

Securing an application requires a robust token-based authentication mechanism. Below is an example of a login controller and a corresponding interceptor for managing session tokens.

@RestController
public class AuthenticationController {

   @Autowired
   private SessionService sessionService;

   @PostMapping("/api/auth/login")
   public ApiResponse performLogin(String account, String secret, String code) {
       User record = userService.findByUsername(account);
       if (record == null || !record.getPassword().equals(secret)) {
           return ApiResponse.error("Invalid credentials");
       }
       String sessionToken = sessionService.createNewToken(record.getId(), account, record.getRole());
       return ApiResponse.success().add("token", sessionToken);
   }
}

@Component
public class SecurityInterceptor implements HandlerInterceptor {

   @Autowired
   private SessionService sessionService;

   @Override
   public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
       // Handle CORS and pre-flight requests
       response.setHeader("Access-Control-Allow-Origin", "*");
       if ("OPTIONS".equalsIgnoreCase(request.getMethod())) return true;

       String authToken = request.getHeader("Authorization");
       if (authToken != null && sessionService.validate(authToken)) {
           return true;
       }

       response.sendError(401, "Unauthorized access");
       return false;
   }
}
   

Database Schema Design

To manage session state across distributed requests, a dedicated token table is essential for tracking user status and expiration times.

CREATE TABLE `session_tokens` (
 `id` BIGINT PRIMARY KEY AUTO_INCREMENT,
 `user_id` BIGINT NOT NULL,
 `username` VARCHAR(100),
 `role` VARCHAR(50),
 `token_string` VARCHAR(255) NOT NULL,
 `created_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
 `expired_at` TIMESTAMP
);
   

System Testing

Quality assurance is conducted through rigorous functional testing. The objective is to validate that the system logic aligns with design specifications. By uitlizing black-box testing, we simulate real-world user scenarios, such as credential verification, role-based access control (RBAC), and CRUD operations on user records, ensuring that the application remains stable and user-friendly under various conditions.
