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
