payment-service 측 에러

2024-09-02T17:36:15.047+09:00 WARN 22508 --- [payment-service] [nio-8084-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.HttpMediaTypeNotAcceptableException: No acceptable representation]

 

해결

해당 에러들은 PaymentResponseDto에 Getter가 없었기 때문에 JSON 직렬화 과정에서 발생한 에러로 @Getter 추가 시 해결

public class PaymentResponseDto {
    private boolean success;
    private Long paymentId;
    private Long orderId;
    private String message;
    private PaymentWay paymentWay;
    private String status;
}

 

Getter 추가 후 에러 해결 완료

@Getter
@Builder
public class PaymentResponseDto {
    private boolean success;
    private Long paymentId;
    private Long orderId;
    private String message;
    private PaymentWay paymentWay;
    private String status;
