Springboot测试es异常：
Springboot自己创建单独创建和利用网站骨架创建,在测试上是存在一些区别的
问题描述：
无法找到@SpringBootConfiguration

原因分析：
此处是自己单独创建,未通过骨架创建,需要告诉测试Springboot启动类(及入口函数),接着可以加上在测试类运行中,提供一些Spring的支持
解决方案：
在测试类中上方加上:
//告诉测试类启动类
@SpringBootTest(classes = ElasticsearchDdemoApplication.class)
或
//在该类中运行测试,并提供spring的一些支持
@RunWith(SpringRunner.class)
//告诉测试类启动类
@SpringBootTest(classes = ElasticsearchDdemoApplication.class)
