If POJOs can be injected Logger objects, why can't they be injected
LoggerFactory objects?
Let MyClass be written:
import org.slf4j.LoggerFactorAdapter;
public class MyClass {
private MyOtherClass m_other1;
private MyOtherClass m_other2;
public MyClass( LoggerFactorAdapter loggerFactory )
{
Logger logger = loggerFactory.getLogger(MyClass.class);
m_other1 = new MyOtherClass( loggerFactory, 10 );
m_other2 = new MyOtherClass( loggerFactory, 20 );
}
}
