I am trying to configure the NCommon NHRepository in my project with Structure Map. How do I stop it from choosing the greediest constructor?
public class NHRepository<TEntity> : RepositoryBase<TEntity>
{
public NHRepository () {}
public NHRepository(ISession session)
{
_privateSession = session;
}
...
}
My structure map configuration
ForRequestedType(typeof (IRepository<>))
.TheDefaultIsConcreteType(typeof(NHRepository<>))
Cheers Jake
You can set the [DefaultConstructor] Attribute for the constructor you wish as a default. In your case, setting it on the NHRepository() constructor would make it the default constuctor for StructureMap to initialize.
Update: well, in the latest version of StructureMap, using .NET 3.5 you can also specify it using the SelectConstructor method:
var container = new Container(x =>
{
x.SelectConstructor<NHRepository>(()=>new NHRepository());
});
Finally, I'm sure you would be able to define it in the XML configuration of StructureMap, but I haven't used that. You could do a little search on it. For more information on the above method, see: http://structuremap.sourceforge.net/ConstructorAndSetterInjection.htm#section3
So +1 for Razzie because this would work if the NHRepository was in my own assembly, instead I choose to wrap the NHRepository with my own Repository like below..
public class Repository<T> : NHRepository<T>
{
[DefaultConstructor]
public Repository()
{
}
public Repository(ISession session)
{
}
}
ForRequestedType(typeof (IRepository<>))
.TheDefaultIsConcreteType(typeof (Repository<>));
