SpringFramework HttpClientErrorException 400 Bad Request, how to POST in java side?

Question

I try to POST an Object to https://api.aftership.com/v4 but got a problem bellow:

org.springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request

My source code:

@Entity

@JsonIgnoreProperties(ignoreUnknown = true)
public class Trackings {
private String tracking_number;
public Trackings() {

}
public Trackings(String tracking_number) {
    super();
    this.tracking_number = tracking_number;
}

@HeaderConfig

public class HttpHeaderConfigs {
private static final HttpHeaders headers = new HttpHeaders();

public HttpHeaderConfigs() {

}

public static HttpHeaders HttpHeaderConfig() {
    headers.set("aftership-api-key", "e7f28250-889d-48ce-80a1-52f4d16XXXX");
    headers.setContentType(MediaType.APPLICATION_JSON);
    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
    return headers;
}

public HttpHeaders getHeaders() {
    return headers;
}
}

@Function to POST

@RequestMapping("/trackings/add")
public void addTracking() {
    final String uri = "https://api.aftership.com/v4/trackings";
    Trackings tracking = new Trackings();
    tracking.setTracking_number("783518514479");
    RestTemplate restTemplate = new RestTemplate();
    HttpEntity<Trackings> entity = new HttpEntity<Trackings>(tracking, HttpHeaderConfig());
    ResponseEntity<String> response = restTemplate.exchange(uri, HttpMethod.POST, entity, String.class);
    System.out.println(response.getBody());
}

And my result I get when enter http://localhost:8080/trackings/add is:

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
400 Bad Request

I tried to solve it. Please help me fix it!!! <3

Can you make Spring log what JSON it is sending? I think you are sending the wrong JSON. — Robin Green, Nov 24 '18 at 16:54
I try @PostMapping("/trackings/add") and get "java.util.NoSuchElementException: No value present" — An Van Nguyen, Nov 24 '18 at 17:01
See https://stackoverflow.com/questions/7952154/spring-resttemplate-how-to-enable-full-debugging-logging-of-requests-responses — Robin Green, Nov 24 '18 at 17:01
Then you can change your mapping something like this @RequestMapping(path="/trackings/add",method=RequestMethod.Post). you have miss-configured mapping — lucid, Nov 24 '18 at 17:03
@PostMapping is available from spring 4.3 onwards so if you want to use post mapping upgrade your spring version to 4.3.+ or you can simply use the approach lucid suggested i.e @RequestMapping(path="/trackings/add",method=RequestMethod.Post) — Praveen Mulchandani, Nov 24 '18 at 17:09
@RequestMapping(path="/trackings/add",method=RequestMethod.Post) return No value present — An Van Nguyen, Nov 24 '18 at 17:15
I used LoggingRequestInterceptor() is refer by by Robin and I got this "I/O error on POST request for "https://api.aftership.com/v4/trackings": Server returned HTTP response code: 400 for URL: https://api.aftership.com/v4/trackings; nested exception is java.io.IOException: Server returned HTTP response code: 400 for URL: https://api.aftership.com/v4/trackings" — An Van Nguyen, Nov 24 '18 at 17:17

[Aftership API][1] You need to serialize Trackings JSON object and add its get and set methods:

@JsonIgnoreProperties(ignoreUnknown = true)
public class MainTracking implements Serializable {

    private Tracking Tracking;

    public String getTracking() {
        return tracking;
    }

    public void setTracking(Tracking tracking) {
        this.tracking = tracking;
    }
}



@JsonIgnoreProperties(ignoreUnknown = true)
public class Tracking implements Serializable {

    private String tracking_number;

    public Tracking() {
    }    

    public Tracking(String tracking_number) {
        setTracking_number(tracking_number);
    }    

    public String getTracking_number() {
        return tracking_number;
    }

    public void setTracking_number(String tracking_number) {
        this.tracking_number = tracking_number;
    }
}

And update on your Controller:

@RequestMapping("/trackings/add")
public void addTracking() {
    final String uri = "https://api.aftership.com/v4/trackings";
    MainTracking mainTracking = new MainTracking();
    Tracking tracking = new Tracking();
    tracking.setTracking_number("7835112328"); // Be careful with     this number has generated different every time.!!
    mainTracking.setTracking(tracking);

    RestTemplate restTemplate = new RestTemplate();
    HttpEntity<MainTracking> entity = new HttpEntity<MainTracking>(mainTracking, HttpHeaderConfig());

    ResponseEntity<String> response = restTemplate.exchange(uri, HttpMethod.POST, entity, String.class);
    System.out.println(response.getBody());
 }
