我的应用程序中有一个接受日志的控制器。当我发送一个空的json对象（'{}'）或有效的请求但有一个或多个空字段时，它会自动反序列化为一个空的logdto对象或一个字段设置为0的logdto（对于数字字段）。我要拒绝具有空字段的请求。
我的控制器：

@PostMapping("new/log")
public ResponseEntity<Log> newLog(@Valid @RequestBody LogDTO logDTO) {
    return new ResponseEntity<>(logService.newLog(logDTO), HttpStatus.OK);
}

logdto对象：

public class LogDTO {

/**
 * The date and time for this specific log, in miliseconds since epoch.
 */
@Min(0)
@NotNull
@JsonInclude(JsonInclude.Include.NON_NULL)
private long epochDate;

/**
 * The heartRate per minute for this specific time.
 */
@Min(0)
@NotNull
@JsonInclude(JsonInclude.Include.NON_NULL)
private int heartRate;

/**
 * The user this log belongs to.
 */
@Min(0)
@NotNull
@JsonInclude(JsonInclude.Include.NON_NULL)
private long userId;

/**
 * The night this log belongs to. Every sleepsession represents one night.
 */
@Min(0)
@NotNull
@JsonInclude(JsonInclude.Include.NON_NULL)
private long sleepSession;

public LogDTO() {
}

public LogDTO(long epochDate, int heartRate, long userId, long sleepSession) {
    this.epochDate = epochDate;
    this.heartRate = heartRate;
    this.userId = userId;
    this.sleepSession = sleepSession;
}
//getters and setters

我也尝试在我的应用程序属性中设置“spring.jackson.default property inclusion=non default”，但它一直将字段设置为“0”。是否有任何方法可以将空字段设置为“null”而不是“0”，或者拒绝验证中的对象？
