在使用springboot做junit测试的有时候会获取不到bean。
具体报错
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘com.scmcc.feemanger.FeemangerApplicationTests': Unsatisfied dependency expressed through field ‘userModelService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ‘com.scmcc.service.UserModelService' available: expected at least 1 bean which qualifies as autowire candidate.

原因是springboot的项目目录有问题，创建的类必须要放在主类的目录下面，问题解决，改正后的目录结构：
解决方案
原因是springboot的项目目录有问题，创建的类必须要放在主类的目录下面，问题解决~
SpringBoot测试类：Could not autowire. No beans of ‘BrandService‘ type found
如题，最近在做项目的过程中发现
SpringBootTest测试类中的BrandService 无法注入。
在idea中，brandService是爆红的。
解决方案
spring boot测试类 包名与main下application.class启动类的包名默认要一致。
即下图中的两个包名都是com.honyelchak.gulimall.product
以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。
