Spring Boot Rest控制器:返回默认错误JSON

@RestController
public class MyController {

    @GetMapping("/api/resource/{id}")
    public ResponseEntity<Object> getResource(@PathVariable String id) {
        // 模拟处理过程中的错误
        if (id.equals("invalid")) {
            throw new InvalidResourceException("Invalid resource ID");
        }

        // 处理正常情况
        // ...

        return ResponseEntity.ok().build();
    }

    @ExceptionHandler(InvalidResourceException.class)
    public ResponseEntity<Object> handleInvalidResourceException(InvalidResourceException ex) {
        // 构建自定义的错误JSON响应
        ErrorDetails errorDetails = new ErrorDetails(HttpStatus.BAD_REQUEST, ex.getMessage(), LocalDateTime.now());

        return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(errorDetails);
    }
}

public class ErrorDetails {
    private HttpStatus status;
    private String message;
    private LocalDateTime timestamp;

    // 构造函数、getter和setter方法省略

    // 可以根据需要添加其他字段，如错误码、错误详情等
}

public class InvalidResourceException extends RuntimeException {
    public InvalidResourceException(String message) {
        super(message);
    }
}
