mac,mysql,jdbc链接问题?报错

jdbc链接mysql数据库在window上就没有问题,但是在mac上就出现了问题,代码如下:

Connection conn = null;

//String sql;

// 加载数据库驱动

Class.forName("com.mysql.jdbc.Driver");

// 获取数据库连接

conn = DriverManager.getConnection("jdbc:mysql://localhost:3307/test",

"AckMan", "wangbingan");

Exception in thread "main" java.sql.SQLException: null,  message from server: "Host '192.168.1.156' is not allowed to connect to this MySQL server"
