Question

我想使用此RestTemplate代码进行远程POST请求。我尝试过：

       public static void main(String[] args) {
    String token = "d778dh";
    URI uri = UriComponentsBuilder.fromUriString("http://localhost:8080/bogus_rest_api/v1")
            .pathSegment(token)
            .build()
            .toUri();
    HttpEntity<PaymentTransaction> request = new HttpEntity<>(new PaymentTransaction());

    RestTemplate restClient = new RestTemplate();
    restClient.getInterceptors().add(new BasicAuthorizationInterceptor("petrov", "password2"));
    ResponseEntity<PaymentResponse> response = restClient.exchange(uri, HttpMethod.POST,
            request, PaymentResponse.class);
    PaymentResponse foo = response.getBody();
    System.out.println("!!! Calling Bogus Gateway " + foo.getTransactionId());

}

对象发送：

@XmlRootElement(name = "payment_transaction")
public class PaymentTransaction {
    public enum Response {
        failed_response, successful_response
    }

    @XmlElement(name = "transaction_type")
    public String transactionType;
    @XmlElement(name = "transaction_response")
    public Response transactionResponse;
    @XmlElement(name = "response_code")
    public Integer responseCode;
    @XmlElement(name = "technical_message")
    public String technicalMessage;
    @XmlElement(name = "message")
    ......
}

收到的对象：

@XmlRootElement(name = "payment_response")
public class PaymentResponse {

    @XmlElement(name = "transaction_type")
    public String transactionType;
    @XmlElement(name = "transaction_id")
    public String transactionId;
    @XmlElement(name = "amount")
    public Integer amount;
    @XmlElement(name = "currency")
    public String currency;

但是由于我必须配置正确的对象转换而导致错误？

我总是得到Null作为回应。你能提出我该如何解决这个问题？
