SpringBoot测试时抛java.lang.IllegalStateException异常

1.我的测试类

@SpringBootTest
@RunWith(SpringRunner.class)
public class MaServiceTest {



    @Autowired
    private MaService maService;


    @Test
    public void delete() {

        maService.delete(1062530611807285249L);

    }
}

2.运行时的异常

java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

3.解决办法

在@SpringBootTest上加入项目中的启动类，我的程序的启动类是NuocheServerApplication.java。对上面的测试类进行修改，得到：

@SpringBootTest(classes = NuocheServerApplication.class) // 修改部分
@RunWith(SpringRunner.class)
public class MaServiceTest {



    @Autowired
    private MaService maService;


    @Test
    public void delete() {

        maService.delete(1062530611807285249L);

    }
}

4.再次运行，程序正常。
