Question

myeclipse5.5 用java 一直连接不上 mysql 5.5，请高手帮忙！！！ 原程序如下：

import java.sql.*;
public class TestJDBC {
public static void main(String args[]){
try{
Class.forName("com.mysql.jdbc.Driver");
}catch(ClassNotFoundException e){
e.printStackTrace();
}

try{
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydata?" +
"useUnicode=true&characterEncoding=GB2312","root","root");
}catch(SQLException ex){
ex.printStackTrace();
}
System.out.println("OK !");
}

}
一下是myeclipse中的截图：
以下是报错的内容：

请高手指点啊！！！！

Answer 1

是你的链接字符串写错了，直接使用 Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydata","root","root"); 如果你非要设置那个字符编码，那么使用下面这一串Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydata?useUnicode=true&characterEncoding=gbk ","root","root");不用链接符号

追问

没错啊！

Answer 2

1,请确认驱动是否有问题。
2，请把两个TRY写在一个里面试试。
3，MYSQL安装是的端口是3306吗，请确认一下。

追问

都对，试了，可仍旧不行！

Answer 3

在我电脑上运行正常。。
Exception in thread "main" java.lang.ExceptionInInitializerError
at com.mysql.jdbc.Util.stackTraceToString(Util.java:351)
都是JDBC JAR包里抛出的错误。
建议下个新的JDBC包试下。
