测试类中的静态内部类识别不到NoSuchBeanDefinitionException解决

问题

测试类里面的静态内部类识别不到

@RunWith(SpringRunner.class)@SpringBootTestpublic class FooTest {    @Autowired    private Bar bar;    @Test    public void bar() {            }    @Component    public static class Bar {    }}

但执行bar测试方法的时候 报错：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.my.app.dao.FooTest$Bar' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}    at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoMatchingBeanFound(DefaultListableBeanFactory.java:1654) ~[spring-beans-5.1.6.RELEASE.jar:5.1.6.RELEASE]        

解决
添加两个额外的注解

@RunWith(SpringRunner.class)@SpringBootTest@ComponentScan@ImportAutoConfigurationpublic class FooTest
