У меня есть этот код, на мой взгляд, для отображения окна ввода и кнопки отправки. (ОБНОВЛЕНО)Метод доступа в контроллере с точки зрения
<form action="/hms/accommodations" method="GET">
<input type="text" name="searchKeyword"/>
<input type="submit" value="Submit"/>
</form>
Как я нажимаю кнопку отправки, мне нужно пройти независимо от пользователя, введенные в поле ввода быть переложены на метод в моем контроллере.
Это метод, который у меня есть в контроллере. (ОБНОВЛЕНО)
@RequestMapping(value = "/hms/accommodations", method = RequestMethod.GET)
public List<Accommodation> listofAccomo(@RequestParam String searchKeyword){
List<Accommodation> searchResult = accommodationService.findAllAccommodationBySearchBox(searchKeyword);
return searchResult;
}
У меня есть это в моем AccommodationService классе:
public abstract List<Accommodation> findAllAccommodationBySearchBox(String searchKeyword);
И это на другом классе:
public List<Accommodation> findAllAccommodationBySearchBox(String searchKeyword){
TypedQuery<Accommodation> searchResult = em.createNamedQuery("findAllAccommodationBySearch", Accommodation.class);
searchResult.setParameter("searchKeyword",'%'+searchKeyword+'%');
List<Accommodation> result=searchResult.getResultList();
return result;
}
У меня есть эта NamedQuery в моем домене .:
@NamedQueries(
{
@NamedQuery(
name = "findAllAccommodationBySearch",
query = "SELECT a FROM Accommodation a WHERE a.person.firstName LIKE :searchKeyword OR a.person.middleName LIKE :searchKeyword OR a.person.lastName LIKE :searchKeyword OR a.room.roomNumber LIKE :searchKeyword OR a.person.pvId LIKE :searchKeyword OR a.startDate LIKE :searchKeyword OR a.endDate LIKE :searchKeyword"
)
})
Что происходит заключается в том, что когда я нажимаю кнопку «Отправить» после ввода, он перенаправляется на ту же страницу, но с другим URL-адресом, но, похоже, он не получает доступ к моему методу Controller, потому что он не возвращает значение, которое он должен был вернуть. Что я упускаю здесь? Надеюсь, кто-то может помочь. Благодаря!
EDIT: Это мой класс кода контроллера.

Можете ли вы предоставить полный код класса контроллера? – developer
@javaguy Я отредактировал вопрос и включил код класса контроллера. –
