jsp连接sql数据库

使用工具:myeclipse 2016、sql server2008、Microsoft JDBC Driver 6.0

<%@ page language="java" import="java.util.*" contentType="text/html; charset=utf-8"%>
<%@page import="java.sql.*" %>

<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>


<!DOCTYPE html>
<html>
  <head>
    <title>查询所有用户的记录</title>
    <style>
    td{width:100px;border:2px solid;}
    </style>
  </head>
  <body>
    <%
      String url = "jdbc:sqlserver://localhost:1433;DatabaseName=shopping";//连接数据库的url地址
      String user = "sa";//登录数据库的用户名
      String password = "12345";//登录数据库的用户名的密码
      Connection conn = null;
     try{
      Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");//加载JDBC驱动程序
      }
      catch(Exception ex)
      {
        System.out.println("错误"+ex);
      }
     try{
        conn = DriverManager.getConnection(url,user,password);//链接数据库
      }
     catch(Exception ex)
      {
        System.out.println("连接数据库错误"+ex);
      }

        Statement stmt = conn.createStatement();//创建语句对象Statement
        String queryAll = "SELECT * FROM items";//查询所有的用户
        ResultSet rs = stmt.executeQuery(queryAll);
    while(rs.next()){
    %>
    <table>
    <tr>
        <td><%=rs.getInt("id") %></td>
        <td><%=rs.getString("name") %></td>
        <td><%=rs.getString("city") %></td>
        <td><%=rs.getInt("price") %></td>
        <td><%=rs.getInt("number") %></td>
        <td><%=rs.getString("picture") %></td>
    </tr>
    <%} %>
    </table>
  </body>
</html>

注意:

驱动包必须放到项目的WebRoot/web-inf/lib下

如图:lib
