未找到类型的即时转换器：java.time.ZonedDateTime

Posted 2021-04-01

我正在尝试从范围中获取较低/较高的端点，并且当要获取这些较低/较高的端点时，它会抛出异常，如下所示：

java.lang.IllegalArgumentException: No instant converter found for type: java.time.ZonedDateTime

    at org.joda.time.convert.ConverterManager.getInstantConverter(ConverterManager.java:166)
    at org.joda.time.base.BaseDateTime.<init>(BaseDateTime.java:171)
    at org.joda.time.DateTime.<init>(DateTime.java:257)
    at pl.azimuthit.flightmap.airportstatus.AirportStatusProviderImpl.getForecastForFlightOverall(AirportStatusProviderImpl.java:81)

代码：

@Override
    public WeatherStatus getForecastForFlightOverall(String icao, ... flight) {

       ...

        if ( flightmapIntegration.isMetIntegrationEnabled() ) {
            List<ViewFlightAirportDTO> airports = getFlightRouteAirports(icao, flight);
            Range<ZonedDateTime> range = getRange(airports);

            DateTime from = range.lowerEndpoint() == null ? null : new DateTime(range.lowerEndpoint());
            DateTime to = range.upperEndpoint() == null ? null : new DateTime(range.upperEndpoint());

            try {
               ....
            }
        }

        return status != null ? status : WeatherStatus.UNKNOWN;
    }

getRange方法：

 private Range<ZonedDateTime> getRange(List<...> ...) {

        if ( ....isEmpty() ) {
            return Range.singleton(ZonedDateTime.now());
        }

        Range<ZonedDateTime> result = validityRangeOf(....get(0));

        for (int i = 1; i < flightAirports.size(); i++) {
            result = result.span(validityRangeOf(....get(i)));
        }

        return result;
    }

validtyRangeOf方法：

private Range<ZonedDateTime> validityRangeOf(ViewFlightAirportDTO firstAirport) {
        return Range.closed(firstAirport.getValidFrom(), firstAirport.getValidTill());
    }

编辑我可以这样，但不知道如何完成。我的意思是从/到也可以是ZonedDateTime的类型，但我不知道如何使用较低/较高的端点创建它的对象

   ZonedDateTime from = range.lowerEndpoint() == null ? null : new ZonedDateTime(range.lowerEndpoint());
            ZonedDateTime to = range.upperEndpoint() == null ? null : new ZonedDateTime(range.upperEndpoint());

答案

ZonedDateTime zonedDateTime = ZonedDateTime.now(); DateTime dateTime = new DateTime(zonedDateTime); // will cause IllegalArgumentException
