1case) 가장 많은 경우로 entity class 명으로 안한 경우

@Data
@Entity(name = "user")
public class User {

	@Id
	@GeneratedValue(strategy = GenerationType.AUTO)
	private int id;
	
	@Column
	private String name;
}

 

	@Query(value = "select us from User us")
	public List<User> selectJpqlUser();

 

2case)  @Table 어노테이션 이용

@Data
@Entity(name = "user")

형태를 아래와 같이 변경

@Data
@Entity
@Table(name = "user")
public class User {

 

3case)  datasource 설정이 잘 안되어져 있을때
