You can use @Transient annotation which tells the JPA provider to not persist the field in the database.

Specifies that the property or field is not persistent. It is used to
annotate a property or field of an entity class, mapped superclass, or
embeddable class.

 @Entity
 public class Employee 
 @Id int id;
 @Transient User currentUser;
 ...
 

You may Refer the API

For ignoring any field from your model you can use @Transient (javax.persistence.Transient) annotation so it will not check that column in your db.

if you want to use that column for calculation purpose and don't want to Store in database then @Transient annotation works for you.

Like if you don't want to Store column PassengerAddress then declare in this way.

@Transient
private String PassengerAddress;

Or other option is use partial class i.e remove that column from class. only use particular columns which yo want to store in database.

If you want your column not to be inserted or updated, you can make the column insertable=false and updatable=false.

Quoting from JBoss Hibernate Docs:

insertable (optional): whether or not the column will be part of the
insert statement (default true)

updatable (optional): whether or not
the column will be part of the update statement (default true)

If you want PassengerPhoneNo not to be inserted or updated in the database table you can have insertable = false and updatable=false as shown below:

@Column(name="PassengerPhoneNo", insertable = false, updatable = false)
private String PassengerPhoneNo;
