今天写了个测试类：由于测试类的包路径和代码包路径不一致，所以会报一下错误：
十月 31, 2018 4:20:42 下午 org.springframework.boot.test.context.SpringBootTestContextBootstrapper buildDefaultMergedContextConfiguration
信息: Neither @ContextConfiguration nor @ContextHierarchy found for test class [org.sdb.project.data.service.TransTest], using SpringBootContextLoader
十月 31, 2018 4:20:42 下午 org.springframework.test.context.support.AbstractContextLoader generateDefaultLocations
信息: Could not detect default resource locations for test class [org.sdb.project.data.service.TransTest]: no resource found for suffixes {-context.xml, Context.groovy}.
十月 31, 2018 4:20:42 下午 org.springframework.test.context.support.AnnotationConfigContextLoaderUtils detectDefaultConfigurationClasses
信息: Could not detect default configuration classes for test class [org.sdb.project.data.service.TransTest]: TransTest does not declare any static, non-private, non-final, nested classes annotated with @Configuration.
java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test

解决问题： 更改测试的包路径，修改为和代码路劲一直即可。
