測試類

package com.ydfind.controller;

import com.ydfind.MainApp;
import com.ydfind.service.impl.MyServiceImpl;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest(classes = MainApp.class)
@RunWith(SpringRunner.class)
public class MyControllerTest {

    @Autowired
    private MyController myController;

    @Autowired
    private MyServiceImpl myService;

    @Test
    public void testName(){
        System.out.println(myController.getName());
    }

    @Test
    public void testService(){
        myService.getServiceName();
    }
}

結果一

結果二

com.ydfind.controller.MyControllerTest雖然會調用到service包裏代碼，但不會更新service的信息，但com.ydfind.MyControllerTest卻會。
