class.newInstance creates Object with all properties being null

I have a class that needs to be initialized dynamically like this:

void doSth(classsuffix) throws Exception {

    String classname =
            "org.test.classname"+classsuffix; //classsuffix is dynamic

    Class<?> clazz;
    clazz = Class.forName(classname);

    TestInterface test = (TestInterface) clazz.newInstance();

}

Paired with a example class

public class classnameOne implements TestInterface{

    @Inject
    private Logger log;

    // Some more functions and stuff

}

The problem is that log in the classnameOne class will be null when initialized. I need that logger to be there tho, so is there any possibility to initialize injected properties when creating the class with newInstance()?
