2.配置文件
2.1 创建配置文件spring-mvc.xml
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xmlns:context="/schema/context"xmlns:mvc="/schema/mvc"xsi:schemaLocation="/schema/beans /schema/beans/spring-beans.xsd/schema/context /schema/context/spring-context.xsd/schema/mvc /schema/mvc/spring-mvc.xsd"><!--扫描web相关的bean--><context:component-scan base-package="com.tiandh.controller.*" annotation-config="true"/><!--开启springMVC注解模式--><mvc:annotation-driven/><!--视图解析器--><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/view"/><property name="suffix" value=".jsp"/></bean></beans>
2.2创建属性文件jdbc.properties
#数据库驱动jdbc.driver=com.mysql.jdbc.Driver#数据库地址jdbc.url=jdbc:mysql://127.0.0.1:3306/mmall?characterEncoding=utf8#用户名jdbc.username=root#密码jdbc.password=123456
