package com.hncj.demo.service;

public interface Calculation {
    public void add();

    public void s();

    public void m();

    public void d();
}

4.CalculationImpl

package com.hncj.demo.service;

public class CalculationImpl implements Calculation {
    @Override
    public void add() {
        System.out.println("a");
    }

    @Override

6.Mytest 

import com.hncj.demo.service.Calculation;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Mytest {
    @Test
    public void annoTest() {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("application-config.xml");
        Calculation calculation = context.getBean("Calculation", Calculation.class);
        calculation.add();
