我正在学习MySQL,我遇到了这个问题:
找不到适合jdbc的驱动程序:mysql // localhost:3306 / demo?useSSL = false 我已阅读其他解决方案,但它无法正常工作。 这是我的代码:
package jdbc.test;
import java.sql.*;
public class JdbcInsertDemo {
public static void main(String[] args) throws SQLException {
Connection myConn = null;
Statement myStmt = null;
ResultSet myRs = null;
String dbUrl = "jdbc:mysql//localhost:3306/demo?useSSL=false";
// jdbc:mysql//localhost:3306/demo?useSSL=false
String user = "student";
String pass = "student";
try {
myConn = DriverManager.getConnection("jdbc:mysql//localhost:3306/demo?useSSL=false", user, pass);
myStmt = myConn.createStatement();
System.out.println("Inserting a new employee to database\n");
int rowsAffected = myStmt.executeUpdate("Insert into employees" + "(last_name, first_name, email, department, salary)" + "values" + "('Wright' , 'Eric', 'eric.wright@foo.com', 'HR', 33000.00)");
myRs = myStmt.executeQuery("slect * from employees order by last_name");
while(myRs.next()) {
System.out.println(myRs.getString("last_name") + ", " + myRs.getString("first_name"));
}
}
catch(Exception exc) {
exc.printStackTrace();
}
finally {
if (myRs != null) {
myRs.close();
}
}
}
}

我想你忘了在lib文件夹中包含jar文件。将驱动器jar文件放在该文件夹中,然后重试。

有些事情可能是错的。
1:您是否在项目引用中包含了JDBC Jar?
myConn = DriverManager.getConnection("jdbc:mysql//localhost:3306/demo?useSSL=false", user, pass);
另外,简而言之,因为你有'DbUrl' - MyConn可以简化。
String dbUrl = "jdbc:mysql//localhost:3306/demo?useSSL=false";
myConn = DriverManager.getConnection(dbUrl, user, pass);
