java.sql.SQLException: null, message from server: "Host 'macrotea' is not allow

<property name="connection.url">
<![CDATA[
      jdbc:mysql://172.16.109.48:3306/db_hibernate?useUnicode=true&characterEncoding=utf-8
]]>
</property>

1.在main方法中连接数据库则出现:

java.sql.SQLException: null,  message from server: "Host 'macrotea' is not allowed to connect to this MySQL server"

然而这种配置,以web的方式,连接数据库,则不出错

改成如下:

jdbc:mysql://localhost:3306/db_hibernate?useUnicode=true&characterEncoding=utf-8

因此在main中测试,不报错,可以连接数据库

即使修改了hosts

127.0.0.1 172.16.109.48

尚未有效果,估计要进行mysql的设置
