JSP连接SQLserver数据库

1.引入外部jar包
2.编写jsp页面
<%@ page language="java" contentType="text/html; charset=utf-8"   pageEncoding="utf-8"%>
<%@ page  import="java.sql.*" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
<%
    PreparedStatement ps = null;
    Connection ct = null;
    ResultSet rs = null;

    String url = "jdbc:sqlserver://localhost:1433;databaseName=test";
    String user="sa";  //超级管理员
    String password="***********";  //密码

    try {
        //1.加载驱动
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        System.out.println("加载驱动成功！");
    }catch(Exception e) {
        e.printStackTrace();
        System.out.println("加载驱动失败！");
    }
    try {  
        //2.连接
        ct=DriverManager.getConnection( url,user,password);
        System.out.println("连接数据库成功！");
    }catch(Exception e) {
        e.printStackTrace();
        System.out.println("连接数据库失败！");
    }
    
    
    
    out.println("select * from emp"+"<br>");    
    /*尝试查询数据库*/
    try{
    	Statement stmt = ct.createStatement();
    	String sql = "select * from emp";
    	// 执行数据库查询语句
        rs = stmt.executeQuery(sql);
        while (rs.next()) {
            String id = rs.getString("eno");
            String name = rs.getString("ename");
            String age = rs.getString("sex");
            
            out.println("eno:" + id +"\t"+ "ename:" + name +"\t"+"sex:" + age+"<br>");
        }
        if (rs != null) {
            rs.close();
            rs = null;
        }
        if (stmt != null) {
            stmt.close();
            stmt = null;
        }
        if (ct != null) {
            ct.close();
            ct = null;
        }
    }
    catch (SQLException e) {
        e.printStackTrace();
        System.out.println("数据库连接失败");
    }
