this is my entity class
#Entity
#Table(name = "PARENT")
#NamedEntityGraph(name="parent.child",attributeNodes=#NamedAttributeNode("child"))
public class Parent implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "PARENT_ID")
private int id;
#RestResource(exported = false)
#ManyToOne
#JoinColumn(name = "CLIENT_ID", insertable = true, updatable = true)
private Client client;
#ManyToOne
#JoinColumn(name = "CHILD_ID", insertable = true, updatable = true)
private Child child;
#Column(name = "PARENT_ID")
private int parentId;
}
this is provider entity
#Entity
#Table(name = "CHILD")
public class Child implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "CHILD_ID")
private int id;
#Column(name = "CHILD_NAME")
private String childName;
#Version
#Column(name = "PROVIDER_VERSION")
private int version;
// bi-directional many-to-one association to Integration
#OneToMany(mappedBy = "child")
private List<Parent> parents;
}
this id jparepository class
public interface ParentDao extends JpaRepository {
#EntityGraph(value="parent.child",type=EntityGraphType.LOAD)
List<Parent> findById(#Param("parentId") int parentId);
}
I want to update Parent object...as its lazyly loading child.child column can not be null while updating Parent. so I am using Entitygraph.
