spring+springMVC+mybatis 框架整合

配置文件结构图如下：

applicatioContext-dao.xml :

<!-- 第一步：配置数据源 -->
	<context:property-placeholder location="classpath:resource/jdbc.properties" />
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="jdbcUrl" value="${jdbc.url}"></property>
		<property name="driverClass" value="${jdbc.driver}"></property>
		<property name="user" value="${jdbc.username}"></property>
		<property name="password" value="${jdbc.password}"></property>
		<property name="maxPoolSize" value="10"></property>
	</bean>

	<!-- 第二步：创建sqlSessionFactory。生产sqlSession -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
	<property name="dataSource" ref="dataSource"></property>
	<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"></property>
	</bean>
	<!-- 配置mybatis接口代理开发
		* 接口类名和映射文件必须同名
		*　接口类和映射文件必须在同一个目录　下
		* 映射文件namespace名字必须是接口的全类路径名
		*　接口的方法名必须和映射Statement的ｉｄ一致
	 -->
	 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
	 <property name="basePackage" value="com.fly.mapper"></property>
	 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	 </bean>

applicationContext-service.xml:

<!-- 扫描包，加载service类 -->
	<context:component-scan base-package="com.fly.service"></context:component-scan>

springmvc.xml:

<!-- 扫描包，加载controller类 -->
	<context:component-scan base-package="com.fly.controller" />
	<!-- 加载注解 -->
	<mvc:annotation-driven/>
       
	<!-- 拼接返回的视图  /?.jsp -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/" />
		<property name="suffix" value=".jsp" />
	</bean>
	
	
	<!-- 静态资源映射 -->
	<mvc:resources mapping="/res/**" location="/res/" /> 
	<mvc:resources mapping="/common/**" location="/common/" /> 
	<mvc:resources mapping="/image/**" location="/image/" /> 
	
	<!-- 定义文件上传解析器 -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<!-- 设定默认编码 -->
		<property name="defaultEncoding" value="UTF-8"></property>
		<!-- 设定文件上传的最大值5MB，5*1024*1024 -->
		<property name="maxUploadSize" value="5242880"></property>
	</bean>
	
	<!-- 拦截器-->
	<mvc:interceptors>
		<mvc:interceptor>
			<mvc:mapping path="/user/**.html"/>
			<mvc:exclude-mapping path="/user/login.html"/>	
			<mvc:exclude-mapping path="/user/reg.html"/>		
			<bean class="com.fly.interceptor.LoginInterceptor"></bean>
		</mvc:interceptor>
	</mvc:interceptors>
