How to use JDBC in IntelliJ IDEA?

Question

I can't start "Hellow World, JDBC" app.

public static void main(String[] args) {
        String username = "user";
        String password = "pass";
        String databaseUrl = "jdbc:mariadb://localhost:3306/example";

        try{
            Class.forName("org.mariadb.jdbc.Driver");
            ClassLoader.getSystemClassLoader();
            Connection connection = DriverManager.getConnection(databaseUrl, username, password);
        } catch (ClassNotFoundException | SQLException throwables) {
            throwables.printStackTrace();
        }

    }

1. I know then the error in this string . JVM can't find and load class by name, but idea seen this class.

2. I add mariadb connector as a jar lib . It means then idea will feed classpass to jvm when it compiling.

I also add requires org.mariadb.jdbc; in module-info.java , but I have the same error. I've already tried creating new project. It's don't help me too. I really don't know why the JVM can't reached Driver class

Answer 1

The issue was in JDBC driver for mariadb v.2.7.2, 2.7.3, 2.7.4. I solved this problem by simply downgrading to an older version 2.4.4
