我正在重构遗留代码库以使用 Feign，但我遇到了一些问题：

  1. 没有任何 Feign 日志语句被打印到控制台

    • 尽管使用记录器和完整日志级别进行实例化

  2. Feign 没有编码我的 reservationSearch 参数

    • 假装只是POST_toStringObject

假装定义：

public interface EPCReservationClient {
    @RequestLine("POST v1/searchReservations")
    @Headers({"clientId: {clientId}", "Content-Type: application/json", 
              "Authentication: {authentication}"})
    @Body("{reservationSearch}")
    ReservationSearchResponse reservationSearch(
        @Param("authentication") String authentication, //apiToken
        @Param("clientId") String clientId,
        @Param("reservationSearch") 
        ReservationSearch<ReservationSearchParameters> reservationSearch);
}

Feign 实例化

Feign.builder()
    .logger(new Logger.JavaLogger())
    .decoder(new JacksonDecoder())
    .encoder(new JacksonEncoder(new ObjectMapper().findAndRegisterModules()))
    .logLevel(Logger.Level.FULL)
    .target(EPCReservationClient.class, restUrl);

参数类型（不要杀了我，不是我的代码）：

public class ReservationSearch<T> {

    @JsonProperty("hotelID")
    private final int hotelID;
    private final String languageId;
    @JsonProperty("reservationSearchParameters")
    private final T parameters;
    @JsonProperty("reservationID")
    private final List<Long> reservationID;

    public ReservationSearch(int hotelID, T parameters, final List<Long> reservationID) {
        this.hotelID = hotelID;
        this.languageId = "1033";
        this.parameters = parameters;
        this.reservationID = Optional.ofNullable(reservationID)
                                     .orElseGet(Collections::emptyList);
    }

    public static ReservationSearch<ReservationSearchParameters> forLastName(
        int maxRecords, int hotelId, String lastName) {
        return new ReservationSearch<>(hotelId, new ReservationSearchParameters(maxRecords, lastName, null), null);
    }

    public static ReservationSearch<ReservationSearchParameters> forConfirmationNumber(
        int maxRecords, int hotelId, String number) {
        return new ReservationSearch<>(hotelId, new ReservationSearchParameters(maxRecords, null, number), null);
    }

    public static ReservationSearch<ReservationSearchParameters> forReservationId(
            final int maxRecords,
            final int hotelId,
            final String reservationNumber) {
        ReservationSearch<ReservationSearchParameters> reservationSearchParametersReservationSearch = new ReservationSearch<>(
                hotelId,
                new ReservationSearchParameters(
                        maxRecords,
                        null,
                        null),
                Collections.singletonList(Long.valueOf(reservationNumber)));
        return reservationSearchParametersReservationSearch;
    }

    public int getHotelID() {
        return hotelID;
    }

    public String getLanguageId() {
        return languageId;
    }

    public T getParameters() {
        return parameters;
    }

    public List<Long> getReservationID() {
        return reservationID;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) {
            return true;
        }

        if (o == null || getClass() != o.getClass()) {
            return false;
        }

        final ReservationSearch that = (ReservationSearch) o;

        return new EqualsBuilder()
            .append(hotelID, that.hotelID)
            .append(languageId, that.languageId)
            .append(parameters, that.parameters)
            .append(reservationID, that.reservationID)
            .isEquals();
    }

    @Override
    public int hashCode() {
        return new HashCodeBuilder(17, 37)
            .append(hotelID)
            .append(languageId)
            .append(parameters)
            .append(reservationID)
            .toHashCode();
    }

}

预订搜索参数：

public class ReservationSearchParameters {
    private final String travelerLastName;
    private final String confirmationNumber;
    private final int maxRecordsLimit;

    public ReservationSearchParameters(int maxRecordsLimit, String travelerLastName, String confirmationNumber) {
        this.maxRecordsLimit = maxRecordsLimit;
        this.travelerLastName = travelerLastName;
        this.confirmationNumber = confirmationNumber;
    }

    public String getTravelerLastName() { return travelerLastName; }

    public String getConfirmationNumber() { return confirmationNumber; }

    public int getMaxRecordsLimit() { return maxRecordsLimit; }

}

标头 (@Headers和@HeaderMap) 和正文模板 ( @Body) 参数始终被认为是预编码的。只有查询参数（@QueryMap和@Param引用查询参数的 s）才会被 URL 编码。

如果您希望通过 对您的 body 对象进行编码Encoder，则不要提供任何@Body模板，也不要使用@Param（仅用于模板参数）注释您的 body 参数。然后，未注释的 body 参数将被馈送到您的行中Encoder指定的参数。Feign.builder().encoder(new FooEncoder())
