SpringBoot手动获取Bean类

@Component
public class BeanFactoryTest implements ApplicationContextAware {
    private ApplicationContext applicationContext;
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        this.applicationContext=applicationContext;
    }
    public ApplicationContext getApplicationContext() {
        return applicationContext;
    }
}

BlogService blogService=beanFactoryTest.getApplicationContext().getBean(BlogService.class);
