编码组织是：

控制器（SamplesController）属于网关项目
服务（SampleService）及其存储库（SamplePository）属于网关项目中声明为maven依赖项的公共项目

很明显，SampleService注入确实起作用，但它的SampleRepository依赖关系不起作用。由于公共包是一个外部包，我在gateway app主类中相应地设置了@componentscan
尝试
及
与SampleService相关的SampleController（gatewayproject）代码摘录如下：

@RestController @RequestMapping("/samples") public class SamplesController { @Autowired private SampleService service; ......
SampleService（common项目）是
或者也尝试过

@Service @EnableMongoRepositories public class SampleService { private final SampleRepository sr; public SampleService(SampleRepository repository) { sr = repository; } void insert(BaseSampleEntity sample) { this.sr.insert(sample); } public void delete(BaseSampleEntity sample) { this.sr.delete(sample); }
采样地点（普通项目）为
这让我觉得春季启动IOC过程中出现了一些问题。有什么想法吗
提前感谢你的帮助

尝试在Spring boot主应用程序类（即用SpringBootApplication-GateWayApplication.java注释的类）中添加以下注释
另外，正如您所提到的，您不需要用@repository注释repository类，因为它已经由spring数据管理
更新： @SpringBootApplication本身嵌入了ComponentScan注释，因此它会自动扫描所有子目录下的所有类
希望您的目录结构与

com.example --controllers -- SamplesController --service -- SampleService SampleApplication (this is the class that contains @SpringBootApplication & @EnableMongoRepositories)

正如Kumar V建议的，添加

@ComponentScan("org.open_si.udc_common.services") @EnableMongoRepositories(basePackages = {"org.open_si.udc_common.repositories"})
在gateway.application.java中实现了这一点
不幸的是，由于org.open_si.udc_common.services导入，我面临一个新问题：当针对SamplesController发送请求时，我收到一个HTTP 404错误。当删除udc公共服务的组件扫描（以及控制器中对SampleService的引用）时，一切正常
