mysql-connector-java-3.1.12-bin.jar 放在java\jdk1.5\lib\下

con.close();
System.out.println("link success");

以下代码执行能成功
import java.sql.*;
public class ConTest {

private Connection con = null;
public ConTest(){
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
System.out.println("装载成功");

}catch(Exception e){
System.out.println("装载失败");
}
try{
String dbUrl = "jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=gb2312";
String dbUser = "root";
String dbPwd = "1234";
con = DriverManager.getConnection(dbUrl,dbUser,dbPwd);
con.close();
System.out.println("连接成功");
}catch(Exception ee){
System.out.println("连接失败");
}
}

public static void main(String[] args) {

ConTest test = new ConTest();
}

}
