本文解析了在Spring框架中，因未正确使用@Service注解而导致的“No qualifying bean of type”错误。深入探讨了@Service注解的重要性及其在自动装配过程中的作用。

No qualifying bean of type 'com.fwzx.service.RadarService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

报这样的错一般是因为自己的service没有注解@Service，所以找不到，这时候
查看自己的service层的实现类上面有没有注解@Service

如openAiChatModel的路径见：org.springframework.ai.autoconfigure.openai.OpenAiAutoConfiguration.java。@Qualifier注解是用来指定注入的bean的名字，value值需要到源码中查看，在Spring框架中，出现。

确保 MyBatis 或者 MyBatis-Plus 的配置文件正确配置了 Mapper 接口的扫描路径。MyBatis 或者 MyBatis-Plus 的配置文件可能存在错误，导致 Mapper 接口无法被正确加载。在 MyBatis 或者 MyBatis-Plus 里，通常需要给 Mapper 接口添加特定的注解，像。如果你使用的是 Spring Boot 和 MyBatis-Plus，可以在主应用类上添加。从你给出的错误信息可知，Spring 应用在启动时碰到了依赖注入问题，具体是在创建。

1、使用@AllArgsContructor注解进行自动装配时，默认是以@Autowired注解装配的，但是其中有一个需要用org.apache.dubbo.config.annotation.@DubboReference注解装配，所以导致自动装配时报错。实例属性对应的类为本系统定义的时，使用@Resource注解装配。旭东怪的个人空间-旭东怪个人主页-哔哩哔哩视频。
