Foreword
Sometimes you need to configure the daily work in the configuration file global variables, because these things will not change, and each mapper will pass the Senate, then also seemed a bit cumbersome, but fortunately mybatis itself is supported by a global variable, today, the work used, and record it.
mybatis can set a global variable, the database can be used for the type of label, such as: dbType=oracle ,dbType=mysql;
ConfigurationProperties by parameter setting, setting is as follows:
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:mybatis/mybatis-config.xml"/> <property name="configurationProperties"> <props> <prop key="dbType">oracle</prop> </props> </property> </bean>
java obtain this parameter can be:
sqlSessionFactory.getConfiguration().getVariables().getProperty("dbType")
to sum up
