1.自己修改的一段mail发送程序! | Copy to clipboard |
Posted by: umbrella Posted on: 2004-03-06 18:16 因需要基于WEB的MAIL发送程序(其实就是取回密码时发送密码),在网上看到一段MAIL程序,现在将其修改为WEB界面SERVLET处理并提交数据库寻找用户名的以发送回密码。大家可研究交流下。另外使用的时候建个表单,把用户名提交到getpost就可以了。 有三个类,一个是数据库类(dbconn.java),一个是MAIL发送类(mymail.java),还有一个是 SERVLET取得表单用户名及一些返回给用户的信息(getpost.java)。 调试此程序需要下载JAVAMAIL包与JAF包。可到SUN公司去下载。 dbconn.java类: package webmail; import javax.sql.*; import java.sql.*; /** * <p>Title: </p> * <p>Description: </p> * <p>Copyright: Copyright 2004</p> * <p>Company: </p> * @author unascribed * @version 1.0 */ public class dbconn { String username;//数据库帐号 String password;//数据库密码 String drivername;//驱动名称 String url;//数据库地址 Connection conn;//连接对象 public dbconn() { } public Connection getconn() throws SQLException,Exception { username="root"; password=""; drivername="org.gjt.mm.mysql.Driver"; url="jdbc:mysql://localhost/news"; Class.forName( drivername ).newInstance(); conn=DriverManager.getConnection(url,username,password); return conn; } } getpost.java类: package webmail; import javax.servlet.*; import javax.servlet.http.*; import javax.sql.*; import java.sql.*; import java.util.*; import java.io.*; /** * <p>Title: </p> * <p>Description: </p> * <p>Copyright: Copyright 2004</p> * <p>Company: </p> * @author unascribed * @version 1.0 */ public class getpost extends HttpServlet{ String username="";//用户名 String pass=null;//用户密码 Connection conn=null;//连接对象 ResultSet rs=null;//结果集 String mail=null;//用户MAIL地址 public getpost() { } public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException { PrintWriter out=response.getWriter(); this.username=(String)request.getParameter("username"); System.out.println("取得用户名"); try { Check(username); } catch(Exception e) { System.out.println("连接出错!"); } if(pass!=null) { System.out.println("准备建立MAIL对象"); mymail themail = new mymail(); themail.setNeedAuth(true);//设置是否需要MAIL帐号与密码验证 themail.setSubject("你的密码"); themail.setBody("你的用户名是:"+this.username+" 你的密码是:"+this.pass); themail.setTo(this.mail); themail.setFrom("crhwan@21cn.com"); themail.setNamePass("username","password");//在此输入你的MAIL帐号与密码 if(themail.sendout() == false) { return; } String ok=new String("发送成功,密码已发送到你注册时的MAIL信箱地址,请查收!".getBytes("GBK"),"ISO-8859-1"); out.println("<script language='javascript'>alert('"+ok+"');history.back();</script>"); } else { System.out.println("对不起,发送失败!"); String no=new String("对不起,没有找到你的用户名!".getBytes("GBK"),"ISO-8859-1"); out.println("<script language='javascript'>alert('"+no+"');history.back();</script>"); return; } } public void Check(String username) throws Exception,SQLException { try { dbconn get=new dbconn(); conn=get.getconn(); String name=username; Statement query=conn.createStatement(); String sql="select * from userlist where username='"+name+"'"; rs=query.executeQuery(sql); System.out.println("准备取得密码"); if(!rs.next()) { System.out.println("对不起,没有找到你的用户名!"); this.pass=null; return; } else { this.mail=rs.getString("f_email"); this.pass=rs.getString("password"); } } catch(Exception e) { System.out.println("数据出错!"); } } } mymail.java类: package webmail; import java.util.*; import javax.mail.*; import javax.mail.internet.*; import java.util.Date; import javax.activation.*;

Posted by: struggle Posted on: 2004-03-08 14:35 mail发送程序我以前见过一个,也运行了一遍。我手头有一些关于JAVAMAIL的资料,见附件! javamail相关.rar (22.86k) |
