MySQL 存储过程出错，能帮忙看下吗？谢谢~

第一次使用MySQL的存储过程

测试样例如下：

DELIMITER $$



CREATE DEFINER=`wangcheng`@`localhost` PROCEDURE `getAddress`(in n varchar(20),out ret_addr varchar(30))

BEGIN

	declare addr varchar(30);

	select 

    address

into addr from

    custom

where

    custom.name = n;

	set ret_addr=addr;

END

创建成功，使用Java代码调用该存储过程，老是报错

            CallableStatement cstat = conn.prepareCall(sql);

            cstat.registerOutParameter(2,Types.VARCHAR);

            cstat.setString(1,"test");

            cstat.execute();

            System.out.println(cstat.getString(2));

报错原因如下

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: execute command denied to user 'root'@'localhost' for routine 'test.getAddress'

登录用户没错，应该有权限吧

存储过程是使用workbench创建的~~~
