　　Access数据库简单操作：
　　public static Connection getConn() throws Exception {
        Connection conn = null;
        try {
            Properties prop = new Properties();
            prop.put("charSet", "gb2312");
            String url = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=D:\\WSYJ_first.mdb;useUnicode=false;characterEncoding=gbk";

            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            conn = DriverManager.getConnection(url, prop);
            // new String(rs.getBytes("point_x"), "gbk"); 中文处理
            Statement stmt1 = conn.createStatement();
            ResultSet rs = stmt1.executeQuery("select * from CQWS_YY_PT order by objectid");
            if (rs != null) {
                while (rs.next()) {
                    String id = rs.getString("objectid");
                    String lon = rs.getString("point_x");
                    String lat = rs.getString("point_y");
                    System.out.println(id+"\t"+lon + "\t" + lat);
                }
            }

        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return conn;
    }
　　Mysql数据库简单操作:
　　public static Connection getConn() {
        Connection conn = null;
        try {
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            // System.out.println("数据库驱动");
            String url = "jdbc:mysql://localhost:3306/gpsoffset";
            String user = "root";
            String password = "root";
            conn = (Connection) DriverManager
                    .getConnection(url, user, password);
             System.out.println("连接成功");

        } catch (Exception e) {
            e.printStackTrace();
            // System.out.println("连接失败");
        }
        return conn;
    }
　　Sqlite数据库简单操作:
　　package com.wb.sqlite;

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

public class Test {
   
    public static void main(String[] args) throws Exception {
        Class.forName("org.sqlite.JDBC");
        Connection conn = DriverManager.getConnection("jdbc:sqlite:person.db");
        Statement stat = conn.createStatement();
        stat.executeUpdate("drop table if exists people;");
        stat.executeUpdate("create table people (name, occupation);");
        PreparedStatement prep = conn
                .prepareStatement("insert into people values (?, ?);");

        prep.setString(1, "Gandhi");
        prep.setString(2, "politics");
        prep.addBatch();
        prep.setString(1, "Turing");
        prep.setString(2, "computers");
        prep.addBatch();
        prep.setString(1, "Wittgenstein");
        prep.setString(2, "smartypants");
        prep.addBatch();

        conn.setAutoCommit(false);
        prep.executeBatch();
        conn.setAutoCommit(true);

        ResultSet rs = stat.executeQuery("select * from people;");
        while (rs.next()) {
            System.out.println("name = " + rs.getString("name"));
            System.out.println("job = " + rs.getString("occupation"));
        }
        rs.close();
        conn.close();
    }
}
