解决方法：
（1）查看pom.xml文件相关配置是否正确，比如druid的导入
<dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.2.6</version>
</dependency>
（2）配置文件路径错误添加以下配置
@ContextConfiguration(locations= {“classpath*:application.yml”,“classpath*:logback-spring.xml”})
（3）注解中的配置文件添加不全
（4）注解配置文件的路径错误。

解决方法：
（1）查看pom.xml文件相关配置是否正确，比如druid的导入
<dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId><version>1.2.6</version>
</dependency>
（2）配置文件路径错误添加以下配置
@ContextConfiguration(locations= {“classpath*:application.yml”,“classpath*:logback-spring.xml”})
（3）注解中的配置文件添加不全
（4）注解配置文件的路径错误。
