wrote a class to test the link MySQL:
// JDBC URL
static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
static final String DB_URL = "jdbc:mysql://localhost:3306/dbx?useSSL=false";
static final String USER = "root";
static final String PASS = "123456";
public static void main(String[] args) {
Connection conn = null;
Statement stmt = null;
// JDBC
Class.forName("com.mysql.jdbc.Driver");
//
System.out.println("...");
conn = DriverManager.getConnection(DB_URL,USER,PASS);//
...
}
error content:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server
ask the great god to pass by and take a peek at what the problem is
