我有一个内部静态类，如下所示

@component
public class test{
      @Autowired
      LocationRegistry locReg;

     @Component
    public static class LocationRegistry
    {
        private final ConcurrentMap<String, Path> locationPerRequest = new ConcurrentHashMap<>();

        ConcurrentMap<String, Path> getLocationPerRequest()
        {
            return locationPerRequest;
        }
    }

}

这会给出一个错误，通过字段“locationregistry”表示未满足的依赖关系；嵌套的异常是org.springframework.beans.factory.nosuchbeandefinitionexception
它在springboot 1.5.x版本中运行良好，当我转到2.4.3版本时，由于上述错误而失败。
共享完整的堆栈细节，
