spring - joining two tables with non-Primary key attributes using hibernate annotations -

i have table attributes a1(pk), a2, a3

i have table b attributes b1(pk), b2 , b3

now, need join table , b on basis of a3 = b3.

can tell me how in hibernate annotations using join. problem how specify column of table mapped on column of table b in mapping file both column not primary keys.

like this:

b {      @manytoone     @joincolumn(name = "b3", referencedcolumnname = "a3")     privte a;  } 

you have specify in relationship columns joined.

for vise versa:

a {      @onetomany     @joincolumn(name = "a3", referencedcolumnname = "b3")     privte list<b> blist;  }
