java - Spring AOP和方法的结果

我正在使用AOP编写自定义指标服务。这是我的custon注解

@Retention(RUNTIME)
@Target(METHOD)
public @interface Metric {
}

和方面类：

@RequiredArgsConstructor
@Aspect
@Component
@Data
public class MetricAspect {

    Map<Signature, Map<Object, Counter>> metrics = new HashMap<>();

    @AfterReturning("@annotation(Metric)")
    public void afterReturning(JoinPoint joinPoint) {
        Signature signature = joinPoint.getSignature();
        metrics.get(signature).get("Success").increment();
    }
}

我在方法上添加了自定义注释：

@Override
@Metric
public GetCMOwnerInvoiceResponseDTO getCMOwnerInvoice(GetCMOwnerInvoiceRequestDTO getCMOwnerInvoiceRequest) throws ValidationWebFault_Exception {
    GetCMOwnerInvoiceRequest request = wsConversionService.convert(getCMOwnerInvoiceRequest, GetCMOwnerInvoiceRequest.class);
    GetCMOwnerInvoiceResponse response = invoiceService.getCMOwnerInvoice(request);
    return wsConversionService.convert(response, GetCMOwnerInvoiceResponseDTO.class);
}

我需要将方法GetCMOwnerInvoiceResponseDTO对象的结果添加到我的metrics映射中，而不是单词“ Success”。我需要使用哪些参数或注释？

最佳答案

您可以使用returning属性

@AfterReturning("@annotation(Metric)" , returning="returnValue")
public void afterReturning(JoinPoint joinPoint, Object returnValue) {
