@Column(unique=true) does not seem to work

Question

Even though I set the attribute to be @Column(unique=true), I still insert a duplicate entry.

@Entity
public class Customer {

    @Id
    @Ge         


        

Answer 1

I was also facing the similar issue but got it resolved.

• First, drop the table from Database

    drop table Customer;
  

• Stop your spring boot application and launch it again.

  This worked for me.
