SpringBoot框架下基于junit的单元测试类写法

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.boot.test.context.SpringBootTest;
import org.junit.Test;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = Application.class )//这里是启动类
public class TestXXXService {
    @Autowired
    private XXXService ...;

    //@Test
    public void testXXX(){...}
}
