FunctionService

package spring4_Score.ccit;

import org.springframework.stereotype.Service;

@Service
public class FunctionService {
	public String sayHello(String word) {
		return "Hello "+word+" !";
	}
}

         UseFunctionService.java

package spring4_Score.ccit;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;



@Service
public class UseFunctionService {
	@Autowired
	FunctionService functionService;
	public String SayHello(String word) {
		return functionService.sayHello(word);
	}
}

         DiConfig.java

package spring4_Score.ccit;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan("spring4_Score.ccit")
public class DiConfig {

}

         App.java

package spring4_Score.ccit;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;



/**
 * Hello world!
 *
 */
public class App 
{
    public static void main( String[] args )
    {
    	AnnotationConfigApplicationContext context=new AnnotationConfigApplicationContext (DiConfig.class);
		UseFunctionService useFunctionService =
				context.getBean(UseFunctionService.class);
		System.out.println(useFunctionService.SayHello("di"));
		context.close();
    }
}

运行结果
