Ошибка View. Circular view path

Question

коллеги! Я новичок в Spring, и столкнулся с проблемой. Необходимо реализовать функционал поиска по таблице (использую PostgreSQL). Поиск заканчивается ошибкой:

There was an unexpected error (type=Internal Server Error, status=500). Circular view path [search]: would dispatch back to the current handler URL [/search] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

Посмотрел подобные вопросы, ошибка чаще всего связана с отсутствием каких-либо зависимостей в pom.xml, но вроде бы все зависимости для JSP присутствуют. Подскажите, в чем проблема? Спасибо за вашу помощь!

Код DIV'a для поиска:

 <form class="form-inline" method="get" action="search">
  <i class="fas fa-search" aria-hidden="true"></i>
  <input class="form-control form-control-sm ml-3 w-75" type="text" name="keyword" placeholder="Поиск..." aria-label="Search" />
</form>

Код репозитория:

package book.repos;

import java.util.List;

import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;

import book.domain.Advice;

public interface AdviceRepo extends CrudRepository<Advice, Long> {

    List<Advice> findByIdTopic(long idTopic);

     @Query(value = "SELECT c FROM Advice c WHERE c.name LIKE '%' || :keyword || '%'"
                + " OR c.argument LIKE '%' || :keyword || '%'"
                + " OR c.law_argument LIKE '%' || :keyword || '%'")
        public List<Advice> search(@Param("keyword") String keyword);
}

Код сервиса:

package book.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import book.domain.Advice;
import book.repos.AdviceRepo;

@Service
@Transactional
public class AdviceService {
     @Autowired AdviceRepo adviceRepo;

       //Поиск
        public List<Advice> search(String keyword) {
            return adviceRepo.search(keyword);
        }
}

Код контроллера :

    @Controller
    public class AdviceController {

        @Autowired
        private AdviceRepo adviceRepo;

    @Autowired
    private AdviceService adviceService;
        @GetMapping("/search")
        public ModelAndView search(@RequestParam String keyword) {
            List<Advice> result = adviceService.search(keyword);
            ModelAndView mav = new ModelAndView("search");
            mav.addObject("result", result);

            return mav;    
        }

    }

Answer 1

Решил проблему следующим образом: В application.properties надо было прописать spring.mvc.view.prefix и spring.mvc.view.suffix для jsp
