Optimistic locking in JPA Hibernate with a best simple way

Step 1: Remember this annotation

 @Version
 @Column(name="OPTLOCK")
  private long version;

Think of it, add it to the Model @Entity or @Table which you want to apply

 @Entity
public class Employee{
  private @Id
  @GeneratedValue
  Long id;
  private String name;
  private String dept;
  private int salary;
  @Version
  private long version;
    .............
}

So everything is done

Step 2: Get detail in  plenty of optimistic locking
