简单的小日志：
单元测试发现如下错误：

一般可能测试类没有在和启动类放在一样的目录下，一般为根目录。另外错误信息提示很清楚，如果你的测试类在自定义目录下 @SpringBootTest 请加上 class=启动类.class 如下：

@RunWith(SpringRunner.class)
@SpringBootTest(classes= Application.class)
public class DemoApplicationTests { 
    private static Logger logger = LoggerFactory.getLogger(DemoApplicationTests.class);
    @Test
    public void contextLoads() { 
        // ...
    }
}
