spring boot2 - Could not autowire报错

Posted 2021-08-11 之墨_

在测试类中导入@Autowired注释后出现错误

_今天因为_尚硅谷spring boot2_{第11集教程}中内容_{有一点小纰漏}，导致_{踩到了一个坑}

错误内容：

Could not autowired

运行程序后报错：

org.springframework.beans.factory.UnsatisfiedDependencyException: 
Error creating bean with name 'check.springtest.NaniApplicationTest': 
Unsatisfied dependency expressed through field 'person';
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type 'check.springtest.bean.Person' available: 
expected at least 1 bean which qualifies as autowire candidate. 
Dependency annotations: 
{@org.springframework.beans.factory.annotation.Autowired(required=true)}

出错原因：

没有在person类上面添加@Component，它的作用是：把普通Java对象实例化到spring容器中

问题解决
