Метод save(User) не определен для типа UserRepositoryJava(67108964). ⇐ JAVA

[Гость]

I'm new to Java and Spring Boot. I created a Spring Boot project. and I created an entity class with this code:

package com.example.TEST_WEB; import javax.persistence.*; @Entity @Table(name="users") public class User { @Id //Strategy = GenerationType. IDENTITY : La génération de la clé primaire se fera à partir d’une Identité propre au SGBD. // Il utilise un type de colonne spéciale à la base de données. @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @Column(nullable = false, unique = true, length = 45) private String email; @Column(nullable = false, length = 64) private String password; @Column(name = "first_name", nullable = false, length = 20) private String firstName; @Column(name = "last_name", nullable = false, length = 20) private String lastName; // getters and setters are not shown public String getEmail() { return this.email; } public void setEmail(String email) { this.email = email; } public String getPassword() { return this.password; } public void setPassword(String password) { this.password = password; } public String getFirstName() { return this.firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return this.lastName; } public void setLastName(String lastName) { this.lastName = lastName; } } I also created an interface with this code:

import com.example.TEST_WEB.User; import org.springframework.data.jpa.repository.JpaRepository; public interface UserRepository extends JpaRepository { } And to test my code, I created this class:

package com.example.TEST_WEB; import static org.assertj.core.api.Assertions.assertThat; import org.junit.jupiter.api.Test; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.autoconfigure.data.jdbc.DataJdbcTest; import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase; import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase.Replace; import org.springframework.boot.test.autoconfigure.orm.jpa.TestEntityManager; import org.springframework.test.annotation.Rollback; import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest; @DataJdbcTest @AutoConfigureTestDatabase(replace = Replace.NONE) //une transaction gérée par un test doit être annulée une fois la méthode de test terminée @Rollback(false) public class UserRepositoryTests { @Autowired private UserRepository repo; @Autowired private TestEntityManager entityManager; // test methods go below @Test public void testCreatUser(){ User user = new User(); user.setEmail("ravikumar@gmail.com"); user.setPassword("ravi2020"); user.setFirstName("Ravi"); user.setLastName("Kumar"); User savedUser = repo.save(user); User existUser = entityManager.find(User.class, savedUser.getId()); // assert c'est pour la vérification assertThat(user.getEmail()).isEqualTo(existUser.getEmail()); } } This gives me two errors:

• 
  The method save(User) is undefined for the type UserRepositoryJava(67108964)
• 
  The method getId() is undefined for the type UserJava(67108964)
