org.hibernate.query.sqm.UnknownEntityException

padde479 · 8. Aug 2023

Hallo zusammen,
ich versuche gerade, mir Angular, Spring Boot und MySQL etwas näher zu bringen. Wenn ich allerdings mein Projekt ausführe, erhalte ich diverse Exceptions derart, dass eine Entität nicht aufgelöst werden kann. Hierzu habe ich folgende Klassen:

Java:

package com.inn.cafe.dao;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.repository.query.Param;

import com.inn.cafe.POJO.User;

public interface UserDao extends JpaRepository<User, Integer> {
    User findByEmailId(@Param("email") String email);
}

Java:

package com.inn.cafe.POJO;

import java.io.Serializable;

import org.hibernate.annotations.DynamicInsert;
import org.hibernate.annotations.DynamicUpdate;

import jakarta.persistence.*;
import lombok.Data;

@NamedQuery(name = "User.findByEmailId", query = "SELECT u.name FROM cafe.user u WHERE u.email = `email`")

@Data
@Entity
@DynamicUpdate
@DynamicInsert
@Table(name = "user")
public class User implements Serializable {
    /**
     * 
     */
    private static final long serialVersionUID = 3839381239439398222L;
    
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Integer id;
    
    @Column(name = "name")
    private String name;
    
    @Column(name = "contactNumber")
    private String contactNumber;
    
    @Column(name = "email")
    private String email;
    
    @Column(name = "password")
    private String password;
    
    @Column(name = "status")
    private String status;
    
    @Column(name = "role")
    private String role;
}

Wenn ich in der Klasse UserDao die Zeile 9 entferne und in der Klasse User die Zeile 11, dann kann ich mein Projekt starten. Kann mir evtl. jemand weiterhelfen und sagen, wo der Fehler liegt? Lt. Excpetion ist es ein Fehler in named queries, aber die sieht meiner Meinung nach gut aus.

Danke für eure Hilfe!

Hier die Exception:

Could not resolve root entity 'cafe.user'

Ja, "SELECT u FROM User u WHERE ..."

padde479 · 8. Aug 2023

Die DB cafe mit der Tabelle user existiert aber mit den in der Klasse User definierten Spalten.

Mag sein, aber die Query ist kein SQL sondern JPQL -> da gibts keine Tabellen sondern Entities und die Entity heißt ganz einfach User

padde479 · 8. Aug 2023

Ok, danke. Wenn ich aber Zeile 11 in User ändere in

@NamedQuery(name = "User.findByEmailId", query = "select u from User u where u.email=:@email")

ändere, erhalte ich die folgende Ausgabe:

Was stimmt denn mit dem @-Zeichen nicht bzw. wie muss das Statement denn korrekt lauten?

Kommando zurück. Einfach @ entfernen, dann klappt es

padde479 · 8. Aug 2023

Nächste Frage, sorry 😖 In der Klasse User ist die Annotation @Data eingebunden. Die Doku sagt dazu

Code:

Generates getters for all fields, a useful toString method, and hashCode and equals implementations that check all non-transient fields. Will also generate setters for all non-final fields, as well as a constructor.

In meiner Klasse UserServiceImpl habe ich folgende Methode stehen:

Java:

package com.inn.cafe.serviceImpl;

import java.util.Map;
import java.util.Objects;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Service;

import com.inn.cafe.POJO.User;
import com.inn.cafe.constents.CafeConstants;
import com.inn.cafe.dao.UserDao;
import com.inn.cafe.service.UserService;
import com.inn.cafe.utils.CafeUtils;

import lombok.extern.slf4j.Slf4j;

@Slf4j
@Service
public class UserServiceImpl implements UserService {

    @Autowired
    UserDao userDao;
    
    @Override
    public ResponseEntity<String> signup(Map<String, String> requestMap) {
        System.out.println("Inside signup");
        if (validateSignupMap(requestMap)) {
            User user = userDao.findByEmailId(requestMap.get("email"));
            if (Objects.isNull(user)) {
                userDao.save(null);
            } else {
                return CafeUtils.getResponseEntity("Email already exists", HttpStatus.BAD_REQUEST);
            }
        } else
            return CafeUtils.getResponseEntity(CafeConstants.INVALID_DATA, HttpStatus.BAD_REQUEST);
        return null;
    }

    private boolean validateSignupMap(Map<String, String> requestMap) {
        if (requestMap.containsKey("name") && requestMap.containsKey("contactNumber") && requestMap.containsKey("email")
                && requestMap.containsKey("password"))
            return true;
        else
            return false;
    }

    private User getUserFromMap(Map<String, String> requestMap) {
        User user = new User();
        user.setName(requestMap.get("name")); 
        user.setContactNumber(requestMap.get("contactNumber"));
        user.setEmail(requestMap.get("email"));
        user.getPassword(requestMap.get("password"));
        user.setStatus("false");
        user.setRole("user");
        return user;
    }
}

Jetzt bekomme ich die Fehlermeldung

Code:

The method setContactNumber(String) is undefined for the type User

angezeigt. Ich dachte aber, dass diese Methoden automatisch generiert werden durch die Annotation @Data.

padde479 · 8. Aug 2023

Ok, man musste im Package Explorer im Projekt Maven Dependencies ausklappen, das lombok-<VERSION>.jar mit rechts anklicken und dann [Run As] > [Java Aplication] ausführen. Im sich öffnenden Installer den Pfad zur aktuellen eclipse.ini angeben, Install/Update ausführen und anschließend den Installer beenden. In Eclipse geht man anschließend auf [Project] > [Clean] und führt einen Restart von Eclipse durch. Dann entfällt der Fehler und die Methoden werden generiert.

thecain · 8. Aug 2023

Ich würde mir eher mal überlegen, was die ganzen Annotationen tun. @Data ist eigentlich NIE eine gute Idee auf Entities

thecain hat gesagt.:

Wieso?

thecain · 8. Aug 2023

Data implementiert equals über alle Attribute, bei Entities.macht dies u.a. wegen der ID nicht so Sinn.

padde479 · 8. Aug 2023

Was wäre eine (gute) Alternative bzw. die korrekte Vorgehensweise?

thecain · 9. Aug 2023

Nur die Lombok Annotationen zu verwenden die gebraucht werden (Getter, Setter, usw.) Oder kein Lombok einzusetzen bei der Klasse.
Equals und Hashcode implementiere ich, wenn nötig, mit der NaturalId. In deinem Fall also wahrscheinlich der E-mail
