切记：单元测试时需要需要保证有spring boot上下文

@Component 

public class SpringBeanUtils implements ApplicationContextAware { 

private static ApplicationContext applicationContext;   

public static ApplicationContext getApplicationContext() { 

return applicationContext;  

} 

public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        SpringBeanUtils.applicationContext = applicationContext;  

} 

public static Object getBean(String name){ 

return getApplicationContext().getBean(name);  

} 

public static <T> Object getBean(Class<T> T){ 

return getApplicationContext().getBean(T);  

}
}
