Chuzhou Local Products E-commerce Platform Using Spring Boot, Vue.js, and UniApp
Technology Stack
Backend with Spring Boot
Spring Boot simplifies application development by offering auto-configuration and embedded server support. Below is an example of a minimal REST controller implementation:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@RestController
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@GetMapping("/greeting")
public String greet() {
return "Welcome to our platform!";
}
}
This snippet initializes a Spring Boot application exposing a /greeting endpoint.
Frontend using Vue.js
Vue.js enables building interactive interfaces efficiently through raective data binding. Here's how you can create a simple component:
<!DOCTYPE html>
<html>
<head>
<title>Vue Example</title>
<script src="https://unpkg.com/vue@next"></script>
</head>
<body>
<div id="demo">
<p>{{ text }}</p>
<button @click="updateText">Update Text</button>
</div>
<script>
const { createApp } = Vue;
createApp({
data() {
return {
text: 'Hello from Vue!'
};
},
methods: {
updateText() {
this.text = 'Text updated successfully!';
}
}
}).mount('#demo');
</script>
</body>
</html>
This script creates a reactive element that updates its content up on user interaction.
Data Persistence via MyBatis
MyBatis facilitates database interactions by mapping SQL queries to Java objects. It supports dynamic SQL and caching mechanisms for optimized performance.
System Testing
Testing ensures functionality aligns with specifications and identifies potential issues early in development. Key aspects include:
- Functional Tests: Validating core features like authentication and CRUD operations.
- User Acceptance Criteria: Ensuring system behavior matches end-user expectations.
Example test scenarios cover login validation, user management workflows, and error handling procedures.
Code Implementation Highlights
Authentication logic includes token generation and verification:
@PostMapping("/authenticate")
public ResponseEntity<?> authenticate(@RequestBody LoginRequest request) {
User user = userService.findByUsername(request.getUsername());
if (user == null || !passwordEncoder.matches(request.getPassword(), user.getPassword())) {
return ResponseEntity.status(401).body("Invalid credentials");
}
String jwt = jwtTokenProvider.createToken(user.getId());
return ResponseEntity.ok(new AuthResponse(jwt));
}
An interceptor checks tokens before allowing access to protected resources:
@Component
public class AuthInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest req, HttpServletResponse res, Object handler) throws Exception {
String token = req.getHeader("Authorization");
if (jwtTokenProvider.validateToken(token)) {
Long userId = jwtTokenProvider.getUserIdFromToken(token);
req.setAttribute("currentUserId", userId);
return true;
}
res.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
return false;
}
}
Database Schema Sample
A sample table representing products might look like this:
CREATE TABLE Product (
Id BIGINT PRIMARY KEY AUTO_INCREMENT,
Title VARCHAR(100) NOT NULL,
Price DECIMAL(10, 2) NOT NULL,
Details TEXT,
Quantity INT NOT NULL,
CreatedAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
UpdatedAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);
Sample entries could be inserted as follows:
INSERT INTO Product (Title, Price, Details, Quantity)
VALUES
('Smartphone X1', 799.99, 'Latest model smartphone', 50),
('Laptop Pro', 1299.99, 'High-performance laptop', 30);
