Reason for error: Hibernate/JPA generated table conflicts with database reserved words in the User class I created as follows.

@Entity
public class User {

    @Id //main key
    @GeneratedValue(strategy = GenerationType.IDENTITY) //self increment strategy
    private Long id ;//Unique identification of the entity
    private String name;
    private String email;

    protected User(){

    }

    public User(Long id, String name, String email){

        this.email = email;
        this.id = id;
        this.name = name;

    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    @Override
    public String toString(){

        return  String.format("User[id=%d,name='%s',email='%s']",id,name,email);

    }

}

‘user’ conflicts with database reserved word

Solution : Modify the table name and add the following line:

@Table(name="UserLxy")

Re-run the program and remove the fault
