feign.codec.EncodeException: sun.reflect.annotation.TypeNotPresentExceptionProxy

使用feign进行服务调用，被调用方是调用成功的，在返回调用方的过程出现了问题，抛出错误sun.reflect.annotation.TypeNotPresentExceptionProxy。被调用方响应对象序列化是没有问题的，反序列化也是没问题的，但就是在调用方反序列化出现了问题。

调用方

 BaseResponseDto refundLogBaseResponseDto = orderService.saveAndFlushRefundLog(refundLog);

@PostMapping(value = "/payment/saveAndFlushRefundLog",consumes = "application/json")
    BaseResponseDto<RefundLog> saveAndFlushRefundLog(@RequestBody RefundLog refundLog);

被调用方

@PostMapping(value = ""/payment/saveAndFlushRefundLog",consumes = "application/json")
    public BaseResponseDto<RefundLog> saveAndFlushRefundLog(@RequestBody RefundLog refundLog){
        BaseResponseDto<RefundLog> refundLogBaseResponseDto = null;
        try {
        refundLogBaseResponseDto = refundService.saveAndFlushRefundLog(refundLog);
        } catch (Exception e) {
         return new BaseResponseDto<>(StatusCode.FAILURE);
        }
        return refundLogBaseResponseDto;

    }

响应类

@Getter
@Setter
@ToString

public class BaseResponseDto<T> implements Serializable {

    public BaseResponseDto() {
        this.timestamp = DateFormatUtils.format(new Date(),"yyyy-MM-dd HH:mm:ss");
    }

    public BaseResponseDto(Integer resultCode, String resultMessage) {
        this.timestamp = DateFormatUtils.format(new Date(),"yyyy-MM-dd HH:mm:ss");
        this.resultCode = resultCode;
        this.resultMessage = resultMessage;
    }

    public BaseResponseDto(Integer resultCode, String resultMessage, T responseBody) {
        this.timestamp = DateFormatUtils.format(new Date(),"yyyy-MM-dd HH:mm:ss");
        this.resultCode = resultCode;
        this.resultMessage = resultMessage;
        this.responseBody = responseBody;
    }

    public BaseResponseDto(StatusCode statusCode) {
        this.timestamp = DateFormatUtils.format(new Date(),"yyyy-MM-dd HH:mm:ss");
        this.resultCode = statusCode.getStatusCode();
        this.resultMessage = statusCode.getInfo();
    }

    public BaseResponseDto(StatusCode statusCode, T responseBody) {
        this.timestamp = DateFormatUtils.format(new Date(),"yyyy-MM-dd HH:mm:ss");
        this.resultCode = statusCode.getStatusCode();
        this.resultMessage = statusCode.getInfo();
        this.responseBody = responseBody;
    }

    /**
     * 响应码
     */
    private Integer resultCode;

    /**
     * 错误信息
     */
    private String resultMessage;

    /**
     * 具体响应信息
     */
    private T responseBody;

    /**
     * 时间戳
     */
    private String timestamp;

}

debug过程出现问题
feign.codec.EncodeException: sun.reflect.annotation.TypeNotPresentExceptionProxy
被调用方响应对象的序列化和反序列化

猜想，在服务调用的过程中反序列化出现了问题

在被调用方打印返回的BaseResponseDto<RefundLog>这个对象，打印成json看是什么样的内容，然后在调用方把这个json反序列化成BaseResponseDto<RefundLog>，看看能否成功反序列化，这样可以定位问题的原因。

如有帮助，请采纳，十分感谢！

接口已经定义泛型了，为什么你调用的时候接受返回结果没有泛型？
我们一般都是自定义序列方式不用默认的，feign会默认使用mvc的序列化，贴一下我的，希望对你有帮助

/**
 * 自定义mvc序列化规则，使用传说中的mapper
 */
@Configuration
public class WebMvcConfig {
    @Bean
    ObjectMapper jacksonObjectMapper(){
        return JsonUtil.mapper;
    }
}

JsonUtil类->https://blog.csdn.net/qq_34031691/article/details/121495278?spm=1001.2014.3001.5502

把如图的注解去掉试试

参数的类型对吗，参数都改成string试试

建议返回 JOSNObject 类型，然后debug看下返回内容
