1，新建一web工程，将数据库连接包添加入lib文件夹下。 2，新建jsp页面，内容如下： <%@ page language="java" import="java.util.*" import="java.sql.*" pageEncoding="gb2312"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>jsp连接数据库</title> </head> <body> This is my JSP page. <br> <% // 驱动程序名 String driver = "com.mysql.jdbc.Driver"; // URL指向要访问的数据库名scutcs String url = "jdbc:mysql://192.168.10.43:3306/clientmanager"; // MySQL配置时的用户名 String user = "root"; // MySQL配置时的密码 String password = "123"; try { // 加载驱动程序 Class.forName(driver); // 连续数据库 Connection conn = DriverManager.getConnection(url, user, password); if (!conn.isClosed()) System.out.println("Succeeded connecting to the Database!"); // statement用来执行SQL语句 Statement statement = conn.createStatement(); // 要执行的SQL语句 String sql = "select * from tb_hotel"; // 结果集 ResultSet rs = statement.executeQuery(sql); System.out.println("-----------------"); System.out.println("执行结果如下所示:"); System.out.println("-----------------"); String name = null; while (rs.next()) { // 选择hotel_name这列数据 name = rs.getString("hotel_name"); // 输出结果 System.out.println("酒店名：" + "/t" + name); } rs.close(); conn.close(); } catch (ClassNotFoundException e) { System.out.println("Sorry,can`t find the Driver!"); e.printStackTrace(); } catch (SQLException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } %> </body> </html> 3，启动tomcat,访问该页面，此时控制台打印内容为： Succeeded connecting to the Database!
-----------------执行结果如下所示:-----------------hotelname 三味酒店hotelname 悦来客栈hotelname 西湖大酒店hotelname 希尔顿酒店hotelname 咸亨酒店
