一个简单的访问mysql数据库的main方法。

package com.test;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class TestJDBC {

	/**
	 * 入口函数
	 * 
	 * @param arg
	 */
	public static void main(String arg[]) {
		try {
			Connection con = null; // 定义一个MYSQL链接对象
			Class.forName("com.mysql.jdbc.Driver").newInstance(); // MYSQL驱动
			con = DriverManager
					.getConnection(
							"jdbc:mysql://*/liveEpg?useUnicode=true&characterEncoding=UTF-8",
							"root", "*"); // 链接本地MYSQL

			Statement stmt; // 创建声明
			stmt = con.createStatement();

			// 查询数据并输出
			String selectSql = "SELECT othChannelId FROM channel_info";
			ResultSet selectRes = stmt.executeQuery(selectSql);
			while (selectRes.next()) { // 循环输出结果集
				String username = selectRes.getString("othChannelId");
				System.out.println("username:" + username);
			}

		} catch (Exception e) {
			System.out.print("MYSQL ERROR:" + e.getMessage());
		}
	}
