java - 使用流从对象列表中包含的数组检索类型时出错

Optional<List<Spot>> geoData = getGeoCodeBat(geocodeRequestDTO, reportResponseDTO); //declaration of geoData
//**geoData is a list of object**
// **getting syntax error in map**
// **Errors is an array inside geocodes**
geoData.get().stream().map(m -> {
    Arrays.stream(m.getErrors()).forEach(i ->{
        if(i.getType()==1) //Type is an field inside the Errors array
          {
            reportResponseDTO.setStatus(HttpStatus.BAD_REQUEST); //setting bad request in response
             reportResponseDTO.setStatusCode(400); // setting the bad request value
          }
    });

最佳答案

不知道我是否正确回答了您的问题。但是您可以尝试以下方法：

boolean isBadRequest = geoData.orElseGet(Collections::emptyList)
                              .stream()
                              .map(Spot::getErrors)
                              .flatMap(Arrays::stream)
                              .anyMatch(i -> i.getType() == 1);

if (isBadRequest) {
    reportResponseDTO.setStatus(HttpStatus.BAD_REQUEST);
    reportResponseDTO.setStatusCode(400);
}
