 <!--默认本地模式, 需要本地新建mysql数据库-->

                <datasource.tomcat.test-while-idle>true</datasource.tomcat.test-while-idle>
                <datasource.tomcat.test-on-borrow>true</datasource.tomcat.test-on-borrow>
            </properties>
        </profile>
    </profiles>

其中关键节点名称设置：

<activeByDefault>true</activeByDefault>
这样就会默认连接dev数据库。
