Consider:
{code:borderStyle=solid}
@Entity
public class Boy
{
@EmbeddedId
protected PK id;
@CollectionOfElements
protected Collection<Toy> toys;
protected Boy()
{
}
public Boy(String firstName, String lastName)
{
id = new PK(firstName, lastName);
}
public String getFirstName()
{
return id.getFirstName();
}
public String getLastName()
{
return id.getLastName();
}
public Collection<Toy> getToys()
{
return toys != null ? toys : (toys = new LinkedList<Toy>());
}
@Override
public int hashCode()
{
return id.hashCode();
}
@Override
public boolean equals(Object rhs)
{
return rhs == this || (rhs instanceof Boy && id.equals(((Boy) rhs).id));
}
@Override
public String toString()
{
return id.toString();
}
@Embeddable
public static class PK
implements Serializable
{
@Basic
protected String firstName;
@Basic
protected String lastName;
protected PK()
{
}
public PK(String firstName, String lastName)
{
this.firstName = firstName;
this.lastName = lastName;
}
public String getFirstName()
{
return firstName;
}
public String getLastName()
{
return lastName;
}
@Override
public int hashCode()
{
return lastName.hashCode();
}
@Override
public boolean equals(Object rhs)
{
return this == rhs ||
(rhs instanceof PK && firstName.equals(((PK) rhs).firstName) &&
lastName.equals(((PK) rhs).lastName));
}
@Override
public String toString()
{
return String.format("%s %s", firstName, lastName);
}
}
@Embeddable
public static class Toy
implements Serializable
{
@Basic
protected String name;
protected Toy()
{
}
public Toy(String name)
{
this.name = name;
}
public String getName()
{
return name;
}
@Override
public int hashCode()
{
return name.hashCode();
}
@Override
public boolean equals(Object rhs)
{
return this == rhs || (rhs instanceof Toy && name.equals(((Toy) rhs).name));
}
@Override
public String toString()
{
return name;
}
}
}
{code}
{code:borderStyle=solid}
public String foreignKeyColumnName(String propertyName, String propertyEntityName, String propertyTableName, String referencedColumnName)
{
String header = propertyName != null ? addUnderscores( propertyName ) : propertyTableName;
if ( header == null ) throw new AssertionFailure( "NamingStrategy not properly filled" );
return columnName( header + "_" + referencedColumnName );
}
{code}
because referencedColumnName comes in as id.firstName.
DefaultComponentSafeNamingStrategy could:
1. override columnName() and call addUnderscores(columnName) or
2. call addUnderscores(referencedColumnName)
Thanks,
Michael
