用MyEclipse新建WEB项目，跟你新建java项目是同一级别目录下的。要写网页就是JSP了，JSP开发你要学会servlet和jsp，这是最起码的，servlet就是java代码了，jsp类似于html。
第一步：创建一个查询过程，因为在登录时要根据用户名查询用户密码
此步要用到pl/sql编程知识，代码如下：
create or replace procedure sel_user(uname in varchar2,pass out varchar2) is
begin
select users.password into pass from users where users.username=uname and rownum = 1;
end;
第二步：编写登录页面（login.java）（采用纯java+servlet编写）
//login.java如下
package cn.hnu;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class testhtml extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
resp.setContentType("text/html;charset=gbk");
try {
PrintWriter pw = resp.getWriter();
pw.println("html");
pw.println("head");
pw.println("title");
pw.println("用户登录");
pw.println("/title");
pw.println("/head");
pw.println("body");
pw.println("h1用户登录/h1");
pw.println("hr");
pw.println("form method=post action=loginCl");
pw.println("用户名：input type=text name=userNamebr");
pw.println("密nbspnbsp码：input type=password name=passwordbr");
pw.println("input type=submit value=登录");
pw.println("input type=reset value=重置");
pw.println("/form");
pw.println("/body");
pw.println("/html");
} catch (Exception e) {
e.printStackTrace();
// TODO: handle exception
}
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
this.doGet(req, resp);
}
}
第三步：编程成功登录页面（wel.java） //wel.java如下，它主要用于用户正常登录后显示信息给用户
package cn.hnu;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class Wel extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
//防止用户非法登录
HttpSession hs = req.getSession();
String s = (String)hs.getAttribute("pass");
if(s == null){
resp.sendRedirect("login");
}
PrintWriter pw = resp.getWriter();
pw.write("welcome,hello");
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
this.doGet(req, resp);
}
}
第四步：编写login处理页面（loginCl.java）
package cn.hnu;
import java.io.IOException;
import java.sql.*;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class loginCl extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
String u = req.getParameter("userName");
String p = req.getParameter("password");
//查询数据库
String pa=null;
Connection ct = null;
CallableStatement cs = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
ct = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:oracle",
"scott", "tiger");
cs = ct.prepareCall("{call sel_user(?,?)}");
cs.setString(1, u);
cs.registerOutParameter(2, oracle.jdbc.OracleTypes.VARCHAR);
cs.execute();
pa = cs.getString(2);
System.out.println("u=" + u + " p=" + pa);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
if (cs != null) {
cs.close();
}
if (ct != null) {
ct.close();
}
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
//验证用户信息是否合法
if (p.equals(pa)) {
HttpSession hs = req.getSession(true);//防止用户非法登录
hs.setAttribute("pass", "OK");
resp.sendRedirect("wel");
} else {
resp.sendRedirect("login");
}
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
this.doGet(req, resp);
}
}
亲，sql可以换成MySQL
这个没关系的，别的都可以照搬来用
代码：
package FrameText;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class FrameDemo extends JFrame {
JButton jbtwo ,jbHello, jbBye;
public FrameDemo() {
setLayout(new GridLayout(3, 1));// 3行1列布局
JPanel jp1 = new JPanel();// 第一行
JButton jb1 = new JButton("第一个按钮");
JButton jb2 = new JButton("第二个按钮");
JButton jb3 = new JButton("第三个按钮");
jp1.add(jb1);
jp1.add(jb2);
jp1.add(jb3);
add(jp1);
JPanel jp2 = new JPanel();// 第二行
JButton jbtwo = new JButton("第四个按钮");
jp2.add(jbtwo);
add(jp2);
JPanel jp3 = new JPanel();// 第三行
jbHello = new JButton("第五个按钮");
jbBye = new JButton("第六个按钮");
jp3.add(jbHello);
jp3.add(jbBye);
add(jp3);
setSize(380, 180);
setTitle("窗口");
setLocationRelativeTo(null);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setVisible(true);
}
//点击按钮后响应
public static void main(String[] args) {
new FrameDemo();
}
}
网页地址在代码中的java代码写法如下：
packagecom.test;
importjava.lang.reflect.Method;
//实现打开浏览器并跳到指定网址的类
publicclassBareBonesBrowserLaunch{
publicstaticvoidopenURL(Stringurl){
try{
browse(url);
}catch(Exceptione){
}
}
privatestaticvoidbrowse(Stringurl)throwsException{
//获取操作系统的名字
StringosName=System.getProperty("os.name","");
if(osName.startsWith("MacOS")){
//苹果的打开方式
ClassfileMgr=Class.forName("com.apple.eio.FileManager");
MethodopenURL=fileMgr.getDeclaredMethod("openURL",newClass[]{String.class});
openURL.invoke(null,newObject[]{url});
}elseif(osName.startsWith("Windows")){
//windows的打开方式。
Runtime.getRuntime().exec("rundll32url.dll,FileProtocolHandler"+url);
}else{
//UnixorLinux的打开方式
String[]browsers={"firefox","opera","konqueror","epiphany","mozilla","netscape"};
Stringbrowser=null;
for(intcount=0;countbrowsers.lengthbrowser==null;count++)
//执行代码，在brower有值后跳出，
//这里是如果进程创建成功了，==0是表示正常结束。
if(Runtime.getRuntime().exec(newString[]{"which",browsers[count]}).waitFor()==0)
browser=browsers[count];
if(browser==null)
thrownewException("Couldnotfindwebbrowser");
else
//这个值在上面已经成功的得到了一个进程。
Runtime.getRuntime().exec(newString[]{browser,url});
}
}
}
//主方法测试类
publicstaticvoidmain(String[]args){
Stringurl="";
BareBonesBrowserLaunch.openURL(url);
}
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.sql.*;
class LoginFrm extends JFrame implements ActionListener
