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() { 
    
    		// ...
        }
    
    }
