一.spring+mybatis框架的整合:

1.整体文件的预览:  
![这里写图片描述][70]  
备注:spring-config.xml文件(既spring的文件) 在web.xml文件中被加载:加载如下图:  
![这里写图片描述][70 1]

2.配置文件:  
1).applicationContext-mapper.xml(加载了mybatis-config.xml文件)文件的部分代码:

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="locations">
                <list>
                    <value>classpath:db.properties</value>
                </list>
            </property>
        </bean>
        
        <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
            <property name="driverClassName" value="${jdbc.driver}"/>
            <property name="url" value="${jdbc.url}"/>
            <property name="username" value="${jdbc.username}"/>
            <property name="password" value="${jdbc.password}"/>
        </bean>
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            
            <property name="dataSource" ref="dataSource"/>
            
            <property name="configLocation" value="classpath:mybatis-config.xml"></property>
        </bean>
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage" value="cn.itcast.babasport.mapper"/>
        </bean>
    </beans>

2)application-service.xml(事物扫描的包)文件的代码:

<context:component-scan base-package="cn.itcast">
            
            <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        </context:component-scan>

3).applicationContext-transaction.xml(事物文件)代码:

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            
            <property name="dataSource" ref="dataSource"/>
        </bean>
    
        
        <tx:annotation-driven transaction-manager="transactionManager"/>

4).mybatis-config

<typeAliases>
            <package name="cn.itcast.babasport.pojo"/>
        </typeAliases>

5).spring-config.xml

<import resource="config/*.xml"/>

6).在web.xml 加载 spring-config.xml文件

<context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:spring-config.xml</param-value>
        </context-param>
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

二.spring+springmvc的整合:

1.SpringMvc的配置文件:

2.web.xml文件加载springMvc的前端控制器
