JAVA程序连接数据库mysql

1.从MySQLGUITools安装目录找到mysql-connector-java-5.0.4-bin.jar。(此为mysql驱动包可复制到项目文件下)

2.项目右键->构建路径->配置构建路径->库->添加外部JAR->找到mysql-connector-java-5.0.4-bin.jar->确定

完整项目workspace

连接代码如下:

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;

@SuppressWarnings("unused")

public class Conn{

Connection conn=null;

public Connection getConn()

{

try

{

Class.forName("com.mysql.jdbc.Driver").getInterfaces();

}catch(ClassNotFoundException ex){System.out.println(ex.getMessage());}

try{

conn=DriverManager.getConnection("jdbc:mysql://192.168.1.100:3306/mysql","root","1234");

}

catch(Exception e)

{

System.out.println("ConnMySqlerror::"+e.getMessage());

System.out.println(e);

}

return conn;

}

}

测试代码如下:

public class test {

/**

* @param args

*/

public static void main(String[] args) {

// TODO Auto-generated method stub

System.out.println("hello,world");

Conn c0 = new Conn();

c0.getConn();

}

}
