EJB: Dependency injection without Interface

问题

I had this code

@Local  
interface IRepo  
{  //...  
}  

@Stateless  
class Repo implements IRepo  
{  // ..  
}  

class WebS  
{  
@EJB private IRepo repo;  
// ...  
}  

And all worked normally.

But now I remove interface IRepo and make

@Stateless  
class Repo     {  // ..  
}  

class WebS  
{  
@EJB private Repo repo;  
// ...  
}  

and JNDI look up fails.

could not resolve global JNDI name for @EJB for container WebS ...   

Can I make Dependency injection without Interface?

回答1:

You should use

@Stateless
@LocalBean // <-- annotation here
class Repo     {  
}  

class WebS  
{  
@EJB private Repo repo;  
// ...  
}

Make sure you use EJB-3.1-compliant application server
