其实原因很简单：MySQLSyntaxErrorException: Unknown database ‘shouyuan’ -> 大概的意思就是未知的数据库，说明数据库连接出错，然后查看了一下配置，果然是数据库名字写错了，正确的是"shouhuan"而不是"shouyuan"，改过来就启动成功了。

**除了这个之外，还有一个常见的和数据库连接相关的错误就是**：

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

这个基本都是**密码错误**，但是不要以为正确密码是YES，去到配置文件，输入正确的数据库连接密码就OK！
