Spring的bean注入配置：

<?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
        https://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        https://www.springframework.org/schema/context/spring-context.xsd">
<!--    指定扫描的包，这个包下的注解都会生效-->
    <context:component-scan base-package="com.zmy"/>
    <context:annotation-config></context:annotation-config>

</beans>

beans.xml的固定内容其实可以通过点击resources右键new,下方的XmlConfigurationFile中的SpringConfig新建就可以直接带有

mybatis核心配置文件：
