篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了没有正确配置扫描包，提示spring的bean不存在相关的知识，希望对你有一定的参考价值。
如下提示的解决方案：
<!-- 扫描org.infor包下面的java文件，有Spring的相关注解的类，则把这些类注册为Spring的bean -->
<context:component-scan base-package="org.ibaiqi.infor"/>

备注意思是：（org.springframework.beans.factory。创建名为“inforController”的bean时出错:通过字段“inforService”表达的不满足的依赖项;嵌套异常是org.springframe .bean .factory。NoSuchBeanDefinitionException:没有“org.ibaiqi.infor.service.InforService”类型的合格bean:至少有一个bean符合autowire候选条件。依赖注释:{@org.springframework.beans.factory.annotation.Autowired(要求= true),）
