本文實例講述了Java實現基于JDBC操作mysql數據庫的方法。分享給大家供大家參考，具體如下：

									package main;

									import java.sql.Connection;

									import java.sql.DriverManager;

									import java.sql.ResultSet;

									import java.sql.Statement;

									import java.util.ArrayList;

									import java.util.List;

									public class DBConnection {

									  /**

									   * 入口函數

									   *

									   * @param arg

									   */

									  public static List<String> queryUserClosed(String today,String lastMonday) {

									    List<String> beanList = new ArrayList<String>();

									    try {

									      Connection con = null; // 定義一個MYSQL鏈接對象

									      Class.forName("com.mysql.jdbc.Driver").newInstance(); // MYSQL驅動

									      con = DriverManager.getConnection(

									              "jdbc:mysql://localhost:3306/my_db?useUnicode=true&characterEncoding=UTF-8",

									              "root", ""); // 鏈接本地MYSQL

									      Statement stmt; // 創建聲明

									      stmt = con.createStatement();

									      // 查詢數據并輸出

									      StringBuffer sql = new StringBuffer();

									      sql.append(" select reason");

									      sql.append(" from t1");

									      sql.append(" GROUP BY reason");

									      String selectSql = sql.toString();

									      ResultSet selectRes = stmt.executeQuery(selectSql);

									      while (selectRes.next()) { // 循環輸出結果集

									        beanList.add(selectRes.getString("reason"));

									      }

									    } catch (Exception e) {

									      e.printStackTrace();

									      System.out.print("MYSQL ERROR:" + e.getMessage());

									    }

									    return beanList;

									  }

									}
