要点

       @Autowired
       private LSub mSub;

       <bean id="l" class="dd.L"></bean>
       <bean id="lsub" class="dd.LSub"></bean>
       <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor"/>

package dd;
import org.springframework.beans.factory.annotation.Autowired;

public class L {
	@Autowired
	private LSub mSub;
	public void print() {
		mSub.print();
	}
}

package dd;

public class LSub {
	public void print() {
		System.out.println("LSub print");
	}
}
