The cascade = CascadeType.ALL annotation parameter seems to be ignored, what am I doing wrong?
I want the following two java classes make persistent. As you see, the expected 'on delete cascade' clause in the foreign key constraint is missing in the generated sql script.
After debugging I realised, that the flag for generating 'on delete cascade' is always set to false.
Code:
package de.gabo.converter.common.data.rackdesign;
import javax.persistence.*;
import java.util.Set;
@Entity(access = AccessType.PROPERTY)
@Table(name = "HBMTESTPARENT")
public class HbmTestParent
{
Long m_Id;
String m_aParentField;
Set<HbmTestChild> m_children;
@Id
public Long getId()
{
return m_Id;
}
public void setId(Long id_)
{
m_Id = id_;
}
public String getaParentField()
{
return m_aParentField;
}
public void setaParentField(String aParentField_)
{
m_aParentField = aParentField_;
}
@OneToMany( cascade = CascadeType.ALL)
@JoinColumn(name="HBMTESTPARENT_ID")
public Set<HbmTestChild> getChildren()
{
return m_children;
}
public void setChildren(Set<HbmTestChild> children_)
{
m_children = children_;
}
}
Code:
package de.gabo.converter.common.data.rackdesign;
import javax.persistence.*;
@Entity(access = AccessType.PROPERTY)
@Table(name = "HBMTESTCHILD")
public class HbmTestChild
{
Long m_Id;
String m_aChildFild;
HbmTestParent m_parent;
@Id
public Long getId()
{
return m_Id;
}
public void setId(Long id_)
{
m_Id = id_;
}
public String getaChildFild()
{
return m_aChildFild;
}
public void setaChildFild(String childFild_)
{
m_aChildFild = childFild_;
}
@ManyToOne( cascade = CascadeType.ALL, optional = false)
@JoinColumn(name="HBMTESTPARENT_ID")
public HbmTestParent getParent()
{
return m_parent;
}
public void setParent(HbmTestParent parent_)
{
m_parent = parent_;
}
}
