    springboot有包规则的假如你的启动类所在包是com.zpecs,那么只能对com.zpecs.**.*下面的类进行访问,也就是同包,或者是其子包,假如你的某个类放在com.test下则无法访问,此其一
    如果你想使用@Autowire依赖注入,那么你的主类必须是spring托管的,也就是必须有@Component注解或者其子注解,比如@Service等等,此其二
    第三,你的启动类上面,必须有@SpringBootApplication,注解,2.0之前,还要有@EnableAutoConfiguration和@ComponentScan,一般要添加@EnableAsync注解和@EnableTransactionManagement事物托管,此其三,
    排查这3点是否全部符合,若符合,你的问题就解决了
