spring mybatis integration and configuration of affairs

Advance Description:

　　Integration Purpose: To enable mybatis Support Service agent

　　It needs to be done:

　　　　1, will create mybatis objects handed over to spring

　　　　　　① configured with third party data source connection pool

　　　　　　②spring create objects sqlsession

　　　　　　③mybatis interfaces created by mapping objects, spring is not supported by the interface to create objects, we need to give solutions (integration package)

　　　　2, configure the transaction

　　　　　　① Configure the transaction manager

　　　　　　② configure notifications

　　　　　　③ use AOP cut

Specific steps:

　　1, the configuration data source

<! - Configure Data Source ->
    <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
        <property name="url" value="jdbc:mysql://localhost:3306/sms"></property>
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="username" value="root"></property>
        <property name="password" value="1234"></property>
    </bean>

　　2, configures the session factory for creating sqlsession

　　　　Instructions, as long as the session factory configuration, you can get sqlsession objects (see source)

<! - Configure session factory ->
    <bean name="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
        <! - injection data sources, for creating sqlsession ->
        <property name="dataSource" ref="dataSource"></property>
    </bean>

　　3, mapping interface to configure the scan package to create an object mapper

<! - scan package configuration mapping interface for creating an object mapper ->
    <bean name="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <Property name = "basePackage" value = "My"> </ Property> 
　　　　　　<-! specified session factory ->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"></property>
    </bean>

　　4, configure the transaction manager

<! - Configure Transaction Manager ->
    <bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

　　5, configure notifications

<! - Configure Notifications ->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="select*" read-only="true" />
            <tx:method name="find*" read-only="true"/>
            <tx:method name="get*" read-only="true"/>
            <tx:method name="query*" read-only="true"/>
            <tx:method name="*" read-only="false"/>
        </tx:attributes>
    </tx:advice>

　　6, AOP cut

<-! AOP cut ->
    <aop:config>
        <! - entry point ->
        <aop:pointcut expression="execution(* my.service..*.*(..))" id="pc"/>
        <! - Configuration section ->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pc" />
    </aop:config>
