java开发ssm-spring

<!-- 扫描service、dao组件 -->设置自动扫描
    <context:component-scan base-package="com.jointem.hrm.service" />

    <context:component-scan base-package="com.jointem.hrm.dao" />

使用c3p0数据源，使用mysql数据库，数据库连接采用properties文件导入的方法

1.导入properties文件<context:property-placeholder location="classpath:jdbc.properties" />

2.配置c3p0数据源

 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClassName}" />
        <property name="jdbcUrl" value="${jdbc.url}" />
        <property name="user" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="autoCommitOnClose" value="true"/>
        <property name="checkoutTimeout" value="${cpool.checkoutTimeout}"/>
        <property name="initialPoolSize" value="${cpool.minPoolSize}"/>
        <property name="minPoolSize" value="${cpool.minPoolSize}"/>
        <property name="maxPoolSize" value="${cpool.maxPoolSize}"/>
        <property name="maxIdleTime" value="${cpool.maxIdleTime}"/>
        <property name="acquireIncrement" value="${cpool.acquireIncrement}"/>
        <property name="maxIdleTimeExcessConnections" value="${cpool.maxIdleTimeExcessConnections}"/>
    </bean>

3.将连接信息数据交给框架管理，不再 每次使用数据可都要打开链接，关闭等

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

使用sessionfactory使得spring整合mybais

 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.jointem.hrm.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
   </bean>

 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation" value="classpath:mybatis-config.xml"/>/*将mybatis配置引入*/
        <property name="mapperLocations" value="classpath*:*_bean.xml" />/*mybatisSQL语句存储地址*/

   </bean>

 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.jointem.hrm.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>

为切面编程提供方法开头字符串
    <tx:advice id="transactionAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="append*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="modify*" propagation="REQUIRED" />
            <tx:method name="edit*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="remove*" propagation="REQUIRED" />
            <tx:method name="repair" propagation="REQUIRED" />
            <tx:method name="delAndRepair" propagation="REQUIRED" />
            <tx:method name="get*" propagation="SUPPORTS" />
            <tx:method name="find*" propagation="SUPPORTS" />
            <tx:method name="load*" propagation="SUPPORTS" />
            <tx:method name="search*" propagation="SUPPORTS" />
            <tx:method name="datagrid*" propagation="SUPPORTS" />  
            <tx:method name="*" propagation="SUPPORTS" />
        </tx:attributes>

 /*切面编程配置*/
<aop:config>
        <aop:pointcut id="transactionPointcut" expression="execution(* com.jointem.hrm.service..*Impl.*(..))" />/*方法路径*/
        <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" />
    </aop:config>
    </tx:advice>

 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.jointem.hrm.dao" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>
