10 个最佳实践,让您像专业人士一样编写 Spring Boot API,并结合编码示例和解释:
代码解读复制代码@GetMapping("/products/{id}")
public ResponseEntity<Product> getProductById(@PathVariable Long id) {
// ...
}
代码解读复制代码@PostMapping("/users")
public ResponseEntity<User> createUser(@RequestBody User user) {
// ...
}
代码解读复制代码@DeleteMapping("/products/{id}")
public ResponseEntity<?> deleteProduct(@PathVariable Long id) {
if (productService.deleteProduct(id)) {
return ResponseEntity.noContent().build(); // 204 No Content
} else {
return ResponseEntity.notFound().build(); // 404 Not Found
}
}
代码解读复制代码@RestController
public class ProductController {
@Autowired
private ProductService productService;
// ... other controller methods
}
代码解读复制代码@ControllerAdvice
public class ApiExceptionHandler {
@ExceptionHandler(ProductNotFoundException.class)
public ResponseEntity<ErrorResponse> handleProductNotFound(ProductNotFoundException ex) {
// ... create error response with details
return ResponseEntity.status(HttpStatus.NOT_FOUND).body(errorResponse);
}
}
代码解读复制代码public class ProductDto {
private Long id;
private String name;
private double price;
// Getters and setters
}
