请帮忙。我有以下代码：
CheckResponse checkResponse = restTemplate.postForObject(webServiceUrl,checkTaxesWrapper, CheckResponse.class);
CheckResponse是我的POJO，如下所示：
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonPropertyOrder(
{
"errorCode",
"errorMessage",
"merchantTransationId",
"totalFee",
"numberOfWarrants",
"warrantList"
}
)
public class CheckResponse
{
private String errorCode;
private String errorMessage;
private String merchantTransactionId;
private String totalFee;
private String numberOfWarrants;
private List<Warrant>warrantList;
private double taxSum;
private double total;
public double getTaxSum() {
return taxSum;
}
public void setTaxSum(double taxSum) {
this.taxSum = taxSum;
}
public double getTotal() {
return total;
}
public void setTotal(double total) {
this.total = total;
}
public List<Warrant> getWarrantList() {
return warrantList;
}
public void setWarrantList(List<Warrant> warrantList) {
this.warrantList = warrantList;
}
public String getErrorCode() {
return errorCode;
}
public void setErrorCode(String errorCode) {
this.errorCode = errorCode;
}
public String getErrorMessage() {
return errorMessage;
}
public void setErrorMessage(String errorMessage) {
this.errorMessage = errorMessage;
}
public String getMerchantTransactionId() {
return merchantTransactionId;
}
public void setMerchantTransactionId(String merchantTransactionId) {
this.merchantTransactionId = merchantTransactionId;
}
public String getTotalFee() {
return totalFee;
}
public void setTotalFee(String totalFee) {
this.totalFee = totalFee;
}
public String getNumberOfWarrants() {
return numberOfWarrants;
}
public void setNumberOfWarrants(String numberOfWarrants) {
this.numberOfWarrants = numberOfWarrants;
}
@Override
public String toString() {
return "CheckResponse{" +
"errorCode='" + errorCode + '\'' +
", errorMessage='" + errorMessage + '\'' +
", merchantTransactionId='" + merchantTransactionId + '\'' +
", totalFee='" + totalFee + '\'' +
", numberOfWarrants='" + numberOfWarrants + '\'' +
'}';
}
}
正如您所见，我有看起来像这样的Warrant POJO：
@JsonIgnoreProperties(ignoreUnknown = true)
@JsonPropertyOrder(
{
"amount",
"personalId",
"benRefModel",
"ordPartyRefNumber",
"sourceAccount",
"purpose",
"benAddress",
"actualAmount",
"benPlace",
"ordPartyPlace",
"nacinPlacanja",
"transactionID",
"transactionType",
"reservationId",
"urgency",
"purposeCode",
"benRefNumber",
"benName",
"ordPartyTime",
"ordPartyAddress",
"currency",
"currencyDate",
"destinationAmount",
"ordPartyRefModel",
"info"
}
)
public class Warrant {
@JsonProperty("amount")
private String amount;
@JsonProperty("personalId")
private String personalId;
@JsonProperty("benRefModel")
private String benRefModel;
@JsonProperty("ordPartyRefNumber")
private static final String ordPartyRefNumber="";
@JsonProperty("sourceAccount")
private static final String sourceAccount="";
@JsonProperty("purpose")
private String purpose;
@JsonProperty("benAddress")
private String benAddress;
@JsonProperty("actualAmount")
private String actualAmount;
@JsonProperty("benPlace")
private String benPlace;
@JsonProperty("ordPartyPlace")
private String ordPartyPlace;
@JsonProperty("nacinPlacanja")
private String nacinPlacanja="E";
@JsonProperty("transactionID")
private String transactionID;
@JsonProperty("transactionType")
private String transactionType;
@JsonProperty("reservationId")
private String reservationId;
@JsonProperty("urgency")
private String urgency;
@JsonProperty("purposeCode")
private String purposeCode="253";
@JsonProperty("benRefNumber")
private String benRefNumber;
@JsonProperty("benName")
private String benName;
@JsonProperty("ordPartyName")
private String ordPartyName;
@JsonProperty("ordPartyAddress")
private String ordPartyAddress;
@JsonProperty("currency")
private String currency="941";
@JsonProperty("currencyDate")
private String currencyDate;
@JsonProperty("destinationAccount")
private String destinationAccount;
@JsonProperty("ordPartyRefModel")
private String ordPartyRefModel="";
@JsonProperty("info")
private String info;
//getters and setters..
}
我使用了拦截记录传出请求和结果响应的拦截器。我看到了回应：

但是resttemplate返回null ..我不知道为什么..这是堆栈跟踪：

我感谢任何帮助。谢谢
答案 0 :(得分：0)
您可以查看针对Warrant的pojo json注释吗？我认为它们应该与下面的相匹配：
@JsonProperty("transactionID")
private String transactionID;
@JsonProperty("trnFee")
private Integer trnFee;
@JsonProperty("transactionId")
private Integer transactionId;
@JsonProperty("trnMessage")
private String trnMessage;
@JsonProperty("trnStatus")
private Integer trnStatus;
@JsonProperty("realValueDate")
private String realValueDate;
