研究方向

從 org.hyperledger.fabric.contract.execution.JSONTransactionSerializer 和堆疊追蹤中顯示的 GatewayClient.endorse 呼叫開始。使用泛型回傳型別 Response 以及提供的 Asset 和合約介面定義，重現 endorsement 不一致問題。完成的標準是確定是否支援泛型回傳型別，並記錄或修正該行為。

When I call a submit method from application via gateway, I received an Exception below.

Detail message attached to this Exception is ProposalResponsePayloads do not match.

Returned type is a generic class. Both the generic type and the type argument are defined as type in fabric demo .

public interface AbstractAssetContractSubmit {
  Response<Asset> createAsset(Context context, String value);

  Response<Void> deleteAsset(Context context, String assetId);

  Response<Void> updateAsset(Context context, String assetId, String value);
}


@DataType
public final class Response<T> {
  @Property
  private final T body;

  @Property
  private final int code;

  @Property
  private final String msg;

  public Response(@JsonProperty("body") T body, @JsonProperty("code") int code,
      @JsonProperty("msg") String msg) {
    this.body = body;
    this.code = code;
    this.msg = msg;
  }

  public T getBody() {
    return this.body;
  }

  public int getCode() {
    return this.code;
  }

  public String getMsg() {
    return this.msg;
  }
}




@DataType
public final class Asset {
  @Property
  private final String id;

  @Property
  private final String creatorId;

  @Property
  private final String ownerId;

  @Property
  private final long createTime;

  @Property
  private final long lastTransferTime;

  @Property
  private final long lastUpdateTime;

  @Property
  private final String assetValue;

  public Asset(@JsonProperty("id") String id, @JsonProperty("creatorId") String creatorId,
      @JsonProperty("ownerId") String ownerId, @JsonProperty("createTime") long createTime,
      @JsonProperty("lastTransferTime") long lastTransferTime,
      @JsonProperty("lastUpdateTime") long lastUpdateTime,
      @JsonProperty("assetValue") String assetValue) {
    this.id = id;
    this.creatorId = creatorId;
    this.ownerId = ownerId;
    this.createTime = createTime;
    this.lastTransferTime = lastTransferTime;
    this.lastUpdateTime = lastUpdateTime;
    this.assetValue = assetValue;
  }

  public String getId() {
    return this.id;
  }

  public String getCreatorId() {
    return this.creatorId;
  }

  public String getOwnerId() {
    return this.ownerId;
  }

  public long getCreateTime() {
    return this.createTime;
  }

  public long getLastTransferTime() {
    return this.lastTransferTime;
  }

  public long getLastUpdateTime() {
    return this.lastUpdateTime;
  }

  public String getAssetValue() {
    return this.assetValue;
  }
}

Does this chaincode api support java generic type as method return type?
Anyone is welcome to answer this question.
