JAVA web简单的登录界面jsp实现

此次试验所用到的软件是myeclipse10,tomcat7,Dreamweaver,sqlserver2008数据库。可以实现用户使用用户名和密码登录。如果登录成功，页面会显示登录成功，如果密码错误，则页面会显示登录失败。连接数据库使用的事javabean方法，需要实现下载好sqlserver2008的驱动程序，在web project文件夹下的src文件夹下新建包“Bean”，并在此包下新建“DBBean.java”文件。

DBBean.java文件代码如下：

package Bean;
import java.sql.*;
public class DBBean {
    private String driverStr = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
    private String connStr = "jdbc:sqlserver://localhost:1433; DatabaseName=JXP";
    private String dbusername = "sa";
    private String dbpassword = "123456";
    private Connection conn = null;
    private Statement stmt = null;

    public DBBean()
    {
        try
        {
            Class.forName(driverStr);
            conn = DriverManager.getConnection(connStr, dbusername, dbpassword);
            stmt = conn.createStatement();
        }
        catch (Exception ex) {
            System.out.println("数据连接失败！");
        } 

    }

    public int executeUpdate(String s) {
        int result = 0;
        System.out.println("--更新语句:"+s+"\n");
        try {
            result = stmt.executeUpdate(s);
        } catch (Exception ex) {
            System.out.println("执行更新错误！");
        }
        return result;
    }

    public ResultSet executeQuery(String s) {
        ResultSet rs = null;
        System.out.print("--查询语句:"+s+"\n");
        try {
            rs = stmt.executeQuery(s);
        } catch (Exception ex) {
            System.out.println("ִ执行查询错误！");
        }
        return rs;
    }
    public void execQuery(String s){
        try {
            stmt.executeUpdate(s);
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            System.out.println("执行插入错误！");
        }
    }

    public void close() {
        try {
            stmt.close();
            conn.close();
        } catch (Exception e) {
        }
    }
}

在WEBROOT目录下有三个jsp页面文件：分别是login.jsp,logincheck.jsp,loginsuccess.jsp.在login.jsp页面中，可以通过输入用户名、密码，点击登录按钮，实现登录成功loginsucccess.jsp页面的跳转，如果密码错误，则页面会跳转到登录失败的页面。（当然，在进行页面跳转之前，需要在sqlserver2008中新建一个数据库，在数据库目录下新建一个表，并填入表的信息）
