How to select date only from database that storing dob as datatype timestamp without timezone in java

Question

I have a table in PostgreSQL that stores dob as datatype timestamp without timezone example value '1997-12-03 07:00:00'.

My entity class is as follows

    @Table(name = "customer")
    public class Customer implements Serializable{ 
        @Id
        @GeneratedValue(strategy = GenerationType.SEQUENCE)
        @Column(name = "id",unique = true)
        private Long id;

    
        @Column(name = "username")
        @NotNull(message = "username cannot be empty")
        private String username ;

        @Column(name = "dob")
        @JsonFormat(pattern="yyyy-MM-dd")
        private Date dob; 
    }

I want to find all users with dob '1997-12-03'. But as it has a timestamp it's not returning any value. How it can get dob without timestamp using query without changing the datatype of dob?
