JavaWeb实现的超市收银、基于SSM+mysql的 vue便利店收银管理系统实现【文档】【代码过程】

基于Java实现的超市收银、SSM+mysql便利店超市收银管理系统

主要技术

SpringBoot\SSM（两个版本都有）
JSP、JSTL、jQuery、HTML、CSS、JS
Mysql
bootstrap
开发工具和环境
Eclipse\idea（都可以）兼容
Maven
Tomcat 8
JDK 1.8

配置相关代码

<context:property-placeholder location="classpath:db.properties" />
	<!-- 配置数据源 -->
	<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource">
		<!--数据库驱动 -->
		<property name="driverClassName" value="${jdbc.driver}" />
		<!--连接数据库的url -->
		<property name="url" value="${jdbc.url}" />
		<!--连接数据库的用户名 -->
		<property name="username" value="${jdbc.username}" />
		<!--连接数据库的密码 -->
		<property name="password" value="" />
		<!--最大连接数 -->
		<property name="maxTotal" value="${jdbc.maxTotal}" />
		<!--最大空闲连接 -->
		<property name="maxIdle" value="${jdbc.maxIdle}" />
		<!--初始化连接数 -->
		<property name="initialSize" value="${jdbc.initialSize}" />
	</bean>
	
	<!-- 配置MyBatis工厂SqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!--注入数据源 -->
		<property name="dataSource" ref="dataSource" />
		<!--指定核心配置文件位置 -->
		<property name="configLocation" value="classpath:mybatis-config.xml" />
	</bean>

	<!--  配置mapper扫描器 Mapper代理开发（基于MapperScannerConfigurer） -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.mapper" />
	</bean>
