有几天我正在尝试创建Spring应用程序。我很困惑。我有一个名为Event的自定义实体，它有一个名为name的字段。在我的EventRepository中，我创建了一个带查询的自定义方法findOneByName。
package com.example.app.repository;
import com.example.app.entity.Event;
import com.example.app.entity.User;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import java.util.List;
public interface EventRepository extends CrudRepository<Event, Long> {
@Query("SELECT e FROM events e WHERE LOWER(e.name) = LOWER(:name)")
Event findOneByName(@Param("name") String name);
List<Event> findAll();
}
package com.example.app.ServiceImpl;
import com.example.app.Config.Errors;
import com.example.app.entity.User;
import com.example.app.repository.EventRepository;
import com.example.app.repository.UserRepository;
import com.example.app.Service.EventService;
import com.example.app.entity.Event;
import com.example.app.model.RegistrationEvent;
import org.modelmapper.ModelMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
@Service
public class EventServiceImpl implements EventService {
@Autowired
private UserRepository userRepository;
@Autowired
private EventRepository eventRepository;
@Autowired
private ModelMapper modelMapper;
public EventServiceImpl() {
super();
}
@Override
public void register(RegistrationEvent registrationEvent) {
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
String name = auth.getName();
Event event = this.modelMapper.map(registrationEvent, Event.class);
event.setGames(registrationEvent.getGamesToParse());
event.setDescription(registrationEvent.getDescription());
event.setLatitude(registrationEvent.getLatitude());
event.setLongitude(registrationEvent.getLongitude());
event.setName(registrationEvent.getName());
event.setPlayers(registrationEvent.getPlayers());
event.setDate(registrationEvent.getDate());
System.out.println(name);
event.setOwner(this.userRepository.findOneByUsername(name));
this.eventRepository.save(event);
}
}
这就是我得到的错误：
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'eventsController': Unsatisfied dependency expressed through field 'eventService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'eventServiceImpl': Unsatisfied dependency expressed through field 'eventRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'eventRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract com.example.app.entity.Event com.example.app.repository.EventRepository.findOneByName(java.lang.String)!

如果需要，我可以告诉你我的EventController。我认为我的查询错了，但我不知道如何修复它。
答案 0 :(得分：0)
我将直接找到最简单的解决方案：
Event findOneByNameIgnoreCase(String name)
对于问题的起源，我会查看提供的查询本身。在我看来，它是不正确的，它宁愿是：
SELECT * FROM events e WHERE LOWER(e.name) = LOWER(:name)
因为SELECT e可能是格式错误的SQL子句。
