首先报这个错误,你得明白,是什么原因导致的?
答:未引入命名空间,和约束文件
解决方法(加上标红色标记):
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!-- 组件扫描器,主要是spring使用,用来扫描带有指定注解的类,将这些加载成BeanDefinition --> <context:component-scan base-package="com.cyb.spring.service" /> </beans>
约束文件的话,请看:http://www.springframework.org/schema/beans/spring-beans.xsd
