MYSQL的JDBC连接测试程序

下载JDBC驱动程序从MYSQL的HOMEPAGE，解包后找到含有org.gjt.mm.mysql.Driver.class的JAR文件，把它包含到工程文件中。

package com.catmiw.testmysql;

import java.sql.*;

public class MysqlJdbc {
public static void main(String args[]) {
try {
Class.forName("org.gjt.mm.mysql.Driver"); //加载MYSQL JDBC驱动程序
System.out.println("Success loading Mysql Driver!");
}
catch (Exception e) {
System.out.print("Error loading Mysql Driver!");
e.printStackTrace();
}

try {
Connection connect = DriverManager.getConnection(
"jdbc:mysql://localhost/catmiw", "root", "");
//连接URL为 jdbc:mysql//服务器地址/数据库名
//后面的2个参数分别是登陆用户名和密码
System.out.println("Success connect Mysql server!");

Statement stmt = connect.createStatement();
ResultSet rs = stmt.executeQuery("select * from pet");
while (rs.next()) {
System.out.println(rs.getString("name"));

}
}
catch (Exception e) {
System.out.print("get data error!");
e.printStackTrace();
}
}
}

程序运行结果如下：
Success loading Mysql Driver!
Success connect Mysql server!
