如何建立與數據庫

Question

我已經創造了mysql.Now數據庫試圖連接數據庫與程序的連接，但我cant.This是

Class.forName("com.mysql.jdbc.driver"); 
con=DriverManager.getConnection("jdbc:mysql://localhost/hr","abilash","abilash"); 
System.out.println("connected"); 
java.sql.Statement stmt = con.createStatement(); 
System.out.println("Connected Successfully"); 
stmt.executeUpdate("insert into emp (Name) values('"+fnamet.getText()+"') "); 
JOptionPane.showMessageDialog(null,"Item Successfully Added", 
"Confirmation",JOptionPane.INFORMATION_MESSAGE); 

我使用Eclipse和我的我的代碼部分已經加入mysql-connector-java.zip（5.1.25）。我不知道什麼真正的問題是????請幫

Answer 1

你錯過的getConnection（）

更改端口號

con=DriverManager.getConnection("jdbc:mysql://localhost/hr","abilash","abilash"); 

到

con=DriverManager.getConnection("jdbc:mysql://localhost:3306/hr","abilash","abilash");
