java - com.mysql.jdbc.Driver 异常

Question

我正在尝试运行代码

public static Connection getConnection() throws SQLException{
        try {
            Class.forName("com.mysql.jdbc.Driver");
            cn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mysql?zeroDateTimeBehavior=convertToNull [root on Default schema]");
        } catch (ClassNotFoundException | SQLException e) {
            JOptionPane.showMessageDialog(null,e.toString());
        }
        return cn;
    }

但我得到了异常(exception):

对话框:

我在这个项目中添加了分隔符:mysql-connector-java-5.1.36-bin.jar。我做错了什么？

添加mysql connector jar 到您的项目类路径。

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.6</version>
</dependency>
