You don't need to do this. Since a DI framework does this at runtime the generics info is irrelevant. So you can declare the injected type to be whatever you want. To demonstrate:


  | public class GenericsFun
  | {
  |    private Map<String, Integer> foo = new HashMap<String, Integer>();
  | 
  |    public static void main(String[] args) throws Exception
  |    {
  |       HashMap<Long, Long> map = new HashMap<Long, Long>(); 
  |       map.put(5L, 6L);
  |       GenericsFun fun = new GenericsFun();
  |       Field field = GenericsFun.class.getDeclaredField("foo");
  |       field.setAccessible(true);
  |       field.set(fun, map);
  |       fun.throwCCE();
  |    }
  |    
  |    public void throwCCE()
  |    {
  |       Integer boom = foo.get(5L);
  |    }
  | }
