Answer 1

为了让 Springs IoC 容器注入某些东西，它必须定义为 bean 或内部 Spring 对象，例如 ApplicationContext。

所以，定义一个新的 XML 配置文件或使用 Java 配置将服务定义为 bean，然后使用 @Autowired 或 @Inject 注入它。例如

@Autowired
private SomeService someService;

有关详细信息，请参阅 Spring 文档：https://docs.spring.io/spring/docs/current/spring-framework-reference/core.html#beans
