异常原因

org.springframework.beans.factory.BeanCreationException: Error creating bean with name

此为注入异常,bean没有实例到spring容器中，查看spring配置，有没有扫到这个bean或配置这个bean

出现该异常一般为以下几点:

• bean 没有添加注解 或者注解的包引入错误
• xml文件中，配置文件里路径错误

解决方法

补全注解

@Component()
"对象的名称"相当于bean标签的id属性，如果类不属于javaEE三层架构中的任意一层
@Controller
一般用于表现层的注解。 作用和component

@Service
一般用于业务层的注解。 作用和component

@Repository
 一般用于持久层的注解。 作用和component


@Autowired
优先根据类型注入数据,如果有唯一的对象,那么就能成功注入.如果没有唯一的对象,那么就自动根据变量名和ioc容器对象的名称进行匹配,如果变量名称都无法对应上,那么就报错



@Reference
来自dubbo服务 注入的是分布式中的远程服务对象  

查看xml是否正确
