CascadeType.REFRESH in Hibernate
May 27, 2013
For example if the entity Country is associated with State and we are refreshing entity, both the entities Country and State will be refreshed with current session of Hibernate. We need to call refresh() method to refresh the entity.
Country.java
@Entity
public class Country implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name="id")
private int id;
@Column(name="name")
private String name;
@OneToMany(cascade=CascadeType.REFRESH)
@JoinColumn( name="id")
private Set<State> states;
}
State.java
@Entity
@Table(name = "state")
public class State implements Serializable{
private static final long serialVersionUID = 1L;
@Id
@Column(name = "id")
private int id;
@Id
@Column(name = "country_id")
private int countryId;
@Column(name = "name")
private String name;
}
