org.springframework.web.util.NestedServletException: обработка запроса не удалась; Вложенное исключение - java.lang.NumberFormatException: null

Im пытается выполнить полнотекстовый поиск с данными весны mongodb со всеми атрибутами моей модели.org.springframework.web.util.NestedServletException: обработка запроса не удалась; Вложенное исключение - java.lang.NumberFormatException: null

это модель:

@Document 
public class Offre { 
@Id 
private String id; 
@TextIndexed 
private String titreOffre; 
@TextIndexed 
private String descriptionOffre; 
@TextIndexed 
private String date; 
@TextIndexed 
private String lieu; 
}

хранилище

public interface OffreRepository extends MongoRepository<Offre, String>,  OffreRepositoryCustom,PagingAndSortingRepository<Offre, String> { 
Offre findById(String id); 
List<Offre> findAll(); 
} 

public interface OffreRepositoryCustom { 
public List<Offre> findFullTextSearch(String term); 
} 

public class OffreRepositoryImpl implements OffreRepositoryCustom{ 
@Override 
public List<Offre> findFullTextSearch(String term){ 
Query query2 = new Query(); 
query2.addCriteria(Criteria.where("titreOffre").regex(term)); 
return mongoTemplate.find(query2, Offre.class); 
} 
}

это услуга:

public class OffreService { 
@Autowired 
private OffreRepository offreRepository; 
private OffreMapper mapper = new OffreMapper(); 
@Autowired 
MongoTemplate template; 
private Logger logger = Logger.getLogger(UserService.class); 
public List<OffreUi> findFullTextSearch(String term) { 
return mapper.toUIBean(offreRepository.findFullTextSearch(term)); 
} 
}

этот контроллер

@Controller 
@RequestMapping("/offres") 
public class OffreController { 
@Autowired 
private OffreService service; 
private Logger logger = Logger.getLogger(OffreController.class); 
private DataTableResponseMap<OffreUi> offreResponseMap = new DataTableResponseMap<OffreUi>(); 
@RequestMapping (value = "/fulltext/{searchTerm}", method = RequestMethod.GET) 
public String getfullPage(@RequestParam(value = "searchTerm", required = false) String searchTerm,Model model) { 
model.addAttribute("offres", service.findFullTextSearch(searchTerm)); 
return "offre/fulltext"; 
} 
@RequestMapping(value = "/fulltext") 
public @ResponseBody 
Map<String, ? extends Object> fulltext(
@RequestParam(required = false) String iDisplayStart, 
@RequestParam(required = false) String iDisplayLength, 
@RequestParam(value = "searchTerm", required = false) String searchTerm, 
@RequestParam(required = false) String iSortingCols) { 
int pageLength = Integer.parseInt(iDisplayLength); 
int startPage = Integer.parseInt(iDisplayStart)/pageLength; 
Pageable pageable = new PageRequest(startPage, pageLength); 
Page<OffreUi> offres = (Page<OffreUi>) service.findFullTextSearch(searchTerm); 
return offreResponseMap.mapOK(offres.getContent(),offres.getTotalElements()); 
} 
}

это мое мнение: search.jsp:

<html lang="en"> 
<jsp:include page="../menu/header.jsp" /> 
<body> 
<jsp:include page="../menu/topMenu.jsp" /> 
<div> 
<form method="get"action="<c:url value='/offres/fulltext?searchTerm=${searchTerm}'/>"> 
<input type="text" name="searchTerm" id="searchTerm" value="searchTerm"/> 
<input class="btn btn-primary" type="submit" value="Save"> 
</form> 
</div> 
</body> 
</html>

и fulltextsearch.jsp

<html lang="en"> 
<jsp:include page="../menu/header.jsp" /> 
<body>

Ваши параметры являются необязательными строки:

@RequestParam(required = false) String iDisplayStart, 
@RequestParam(required = false) String iDisplayLength,

который затем анализирующие:

int pageLength = Integer.parseInt(iDisplayLength);

, который вызывает NPE.

Вы должны либо проверить нуль первого:

int pageLength = null == iDisplayLength 
         ? 10 
         : Integer.parseInt(iDisplayLength);

или использовать параметр defaultValue для @RequestParam, например,

@RequestParam(required = false, defaultValue="0") String iDisplayStart, 
@RequestParam(required = false, defaultValue="10") String iDisplayLength,

я использовал INT pageLength = NULL == iDisplayLength ? 10 : Integer.parseInt (iDisplayLength); И @RequestParam (требуется = ложь, DefaultValue = "0") Строка iDisplayStart, @RequestParam (требуется = ложь, DefaultValue = "10") Строка iDisplayLength, , но я получаю ту же ошибку может быть, у меня есть проблема в моих критериях в репозитории или между представлением и контроллером. –

@FaycelGsouma. Ваша стекяна показывает, где именно происходит ошибка. 'OffreController.fulltext (OffreController.java:185)' – beerbajay
