spring mybatis 多数据源配置

方法1: 使用自带的多数据源

方法2: 使用 aspectj aop

关键类 : AbstractRoutingDataSource, 在当前线程中绑定一个数据源既 ThreadLocal<DataSource> 变量

public class DynamicDataSource extends AbstractRoutingDataSource {

/**
* 重写此方法,
 * @return DataSource
*/
    @Override
    protected Object determineCurrentLookupKey() {

        return  DataSourceType.getDataBaseType();

    }

}
