The DDL that is being created is putting all of my many to many associations into 1 table, but I actually want each many to many association in its' own table (for other reasons)
Right now hbm2ddl is creating this table (only Table1Key OR Table2Key OR Table3Key should be filled out for any given record, causing this table to have nullable foreign keys):
+-----------+
| xRef |
+-----------+
| Table1Key |
| Table2Key |
| Table3Key |
| RiskKey |
+-----------+
I want hbm2ddl to create the following 3 tables so that there are no nullable foreign keys.
+-----------+ +-----------+ +-----------+
| xRef1 | | xRef2 | | xRef3 |
+-----------+ +-----------+ +-----------+
| Table1Key | | Table2Key | | Table3Key |
| RiskKey | | RiskKey | | RiskKey |
+-----------+ +-----------+ +-----------+
