1、检查jdbc配置文件的参数值后是否有空格
2、检查mysql中user表中是否有xiangzi这个用户
首先通过命令行进入mysql：mysql -u root -p，输入密码...
查看user表中是否有xiangzi用户：
mysql> use mysql;
mysql> select user,host from user
若没有则创建xiangzi用户：
mysql> CREATE USER 'xiangzi'@'localhost' IDENTIFIED BY '123456';
创建完成后给xiangzi赋予访问权限
mysql> grant all privileges on *.* to 'xianzi'@'localhost';
mysql> flush privileges;
over!
