StackOverflowError当试图建立连接到MySQL数据库

Question

当我试图通过使用Java jdbc驱动程序建立到MySQL数据库的连接时，我目前得到一个非常奇怪的错误。这个错误并不能真正帮助我解决问题。我该如何解决这个问题?

请查看下面的代码和错误信息:

public static void main (String[] args) throws ClassNotFoundException, SQLException, InstantiationException, IllegalAccessException{

Class.forName("com.mysql.cj.jdbc.Driver");
Connection connect = DriverManager.getConnection("jdbc:mysql://localhost:3305/testDB", "root", "");
}

附加备注:mysql_connector被添加到类路径中，端口3305是活动的

Answer 1

Connector/J连接建立的文档建议使用这一行。

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

试试。
