我在个人项目中遇到了SpringBoot的问题，我正在Visual Studio Code中进行，以便能够学习语言，错误是在实现安全部分时，由于某种原因，此错误阻止了应用程序的部署，因此我无法看到登录，该错误发生在SecurityConfiguration中。出现的错误是这样的：

  1. Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.
  2. 08:24 ERROR 18740 --- [  restartedMain] o.s.b.d.LoggingFailureAnalysisReporter   :

  9. Description:
  11. Field usuarioServicio in com.example.demo4.security.SecurityConfiguration required a bean of type 'com.example.demo4.service.UsuarioServiceImpl' that could not be found.
  13. The injection point has the following annotations:

我一直试图纠正它与一些类似的问题的答案在这里，但例如，通过把类与标签@Autowired（required=true）在类型UserServiceImpl的变量userService我一直无法修复它，事实上，我的错误也复制在RegistryUserController. Java。
我也看到，它很可能是文件夹分布没有做好，但我不知道会是什么错在我的情况下.如果你需要更多的信息或我为您提供更多的代码，我可以附上它.
我从这里开始学习教程，尽管我更新了它，因为许多库已经过时了（教程是西班牙语的）：https://www.youtube.com/watch?v=0wTsLRxS3gA

有人能帮我解决这个错误吗？

先谢了。

在Sping Boot 应用程序中，依赖注入由IOC容器执行。
要将Java类注解为Spring been，需要使用适当的注解来注解接口或类。

也许你应该列出类所在的文件夹的路径，我的意思是arioServiceImpl，它可能没有被spring扫描过。
另外，一门好的课程可以大大提高学习的效率，也许你应该花更多的时间去寻找一门好的课程，而不是花更多的时间去学习一门相对较老的课程。这只是我个人的建议，祝你学习顺利。
