04（maven+SSH）网上商城项目实战之Spring mybatis项目搭建

1.配置POM.xml文件 ,配置项目所需jar
2.配置WEB.xml:
配置spring监听器

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:application-context.xml</param-value>
</context-param>

<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

3.创建anotation.xml配置文件

<!-- spring扫描 @service -->
<context:component-scan base-package="cn.liu">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<context:annotation-config/>

4. 创建jdbc.properties和jdbc.xml，并配置：

driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/shop?characterEncoding=UTF-8
user=root
password=

<!-- c3p0-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${driverClass}"/>
<property name="jdbcUrl" value="${jdbcUrl}"></property>
<property name="user" value="${user}" />
<property name="password" value="${password}"/>
</bean>

5.配置property.xml文件,读取JDBC配置

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<!-- JDBC的配置 -->
<value>classpath:properties/jdbc.properties</value>
</list>
</property>
</bean>

6.配置mybatis.xml文件

<!-- mybatis org.mybatis.spring.SqlSessionFactoryBean 配置 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mapperLocations" value="classpath:cn/liu/croe/dao/*.xml"/>
<property name="typeAliasesPackage" value="cn.liu.croe.bean"></property>
</bean>

<!-- 扫包 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="cn.liu.croe.dao"/>
</bean>

7.事务管理transation.xml:

<!-- spring 事务 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>

<!-- 开启事务注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>

8.UserInfoDAO.xml
