Spring Boot Search Data by Date (formated in ZonedDateTime)

Question

I want to get list of forms submitted on a particular date. Date will be passed by Admin in Search box (from front end it will be String but in Back end it's ZonedDateTime ).

I've written method in Repository as:

List<AdmissionForm> findByDateContains(ZonedDateTime datePart);

method formation ref : https://www.petrikainulainen.net/programming/spring-framework/spring-data-jpa-tutorial-creating-database-queries-from-method-names/

My Service class background logic is like:

@Transactional(readOnly = true)
public List<AdmissionFormDTO> findByDate(ZonedDateTime datepart){
    return admissionFormRepository.findByDateContains(datepart).stream()
        .map(admissionFormMapper::toDto)
        .collect(Collectors.toList());
}

And My Resource endpoint is like:

@GetMapping("/admissionForms/date")
@Timed
public List<AdmissionFormDTO> findByDate(@RequestParam("date") String date){
    log.debug("REST request to get AdmissionForms by searchTerm :" + date);
    //String to ZonedDateTime method conversion from seperate class
    ZonedDateTime zDate = SupportUtils.convertStringDateToZoneDateTime(date);
    return admissionFormService.findByDate(zDate);
}

I've tried with String search terms and it's working fine but got only trouble with Searching with Date.

I got the exception like:

java.lang.IllegalArgumentException: Parameter value [%2018-11-20T00:00Z%] did not match expected type [java.time.ZonedDateTime (n/a)]' and exception = 'Parameter value [%2018-11-20T00:00Z%] did not match expected type [java.time.ZonedDateTime (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [%2018-11-20T00:00Z%] did not match expected type [java.time.ZonedDateTime (n/a)]'

Give some corrections so I can do search by Date as expected.

EDITED: I changed datatype from ZoneDateTime to LocalDate and solve accordingly as below (Skip timing for now):

My Repository code:

List<AdmissionForm> findByDate(LocalDate datePart);

My Service Class:

@Transactional(readOnly = true)
public List<AdmissionFormDTO> findByDate(String datepart){
    LocalDate localDatePart = SupportUtils.convertStringDateToLocalDate(datepart);
    return admissionFormRepository.findByDate(localDatePart).stream()
        .map(admissionFormMapper::toDto)
        .collect(Collectors.toList());
}

My Resource Entry Point:

@GetMapping("/admissionForms/date")
@Timed
public List<AdmissionFormDTO> findByDate(@RequestParam("date")String date){
    log.debug("REST request to get AdmissionForms by searchTerm :{}",date);
    return admissionFormService.findByDate(date);
}

Thanks for your suggestions, but can't find a way to work with ZondDateTime so we change requirements little bit. Hope others will get help from question and suggested answers here.

Answer 1

Use DateTimeFormat annotation which by default handles the ISO yyyy-MM-dd'T'HH:mm:ss.SSSZ date time format:

public List<AdmissionFormDTO> findByDate(
          @RequestParam("date") @DateTimeFormat ZonedDateTime date) {
  return admissionFormService.findByDate(date);
}

You should further customize @DateTimeFormat if your date doesn't contain seconds fields as in your example.
