第二篇：javamail 发送验证邮件(jspservlet实例源码)

javamail 发送验证邮件(jsp/servlet实例源码)

● 发送email：包括文本邮件、html邮件、带附件的邮件、smtp验证 ● 接收email：pop3远程连接、收取不同mime的邮件、处理附件

首先需要配置环境。需要mail.jar和activation.jar两个包。地址在上，很容易找到。放到classpath中，比如我的是这样. e:\tomcat5\common\lib\activation.jar e:\tomcat5\common\lib\mail.jar e: \tomcat5\common\lib\mailapi.jar e:\tomcat5\common\lib\ e:\jdk1.5\lib\dt.jar e:\jdk1.5\lib\tool.jar e:\jdk1.5\lib\ e:\jdk1.5\bin\ e:\jdk1.5。

//得到中文标题for linux，windows下不用

message.savechanges()

transport transport = mailsession.gettransport(" smtp" )

transport.connect(host user password)

transport.sendmessage(message message.getallrecipients())

transport.close()

}catch(exception e)

{

system.out.println(e)

}

}

public static void main(string args[])

{

/ postmail sm=new postmail()

sm.sethost(" " ) //指定要使用的邮件服务器

sm.setaccount(" xxxxx" " xxxxx" ) //指定帐号和密码

/

param string 发件人的地址

param string 收件人地址

param string 邮件标题

}

}

调用postmail.java的jsp文件：postmail.jsp源代码

< page language=" java" contenttype=" text/html charset=gbk" pageencoding=" gbk" >

<

//set chinese char

//homepage:

request.setcharacterencoding(" gbk" )

response.setcharacterencoding(" gbk" )

response.setcontenttype(" text/html charset=gbk" )

>

< html>

< head>

< meta http-equiv=" content-type" content=" text/html charset=gb2312" > < title> 电子邮件< /title>

< script language=" javascript" >

< !--

function checkdata() {

var txt = document.forms[0].email.value

if(txt.search(" ^\\w+([-+.]\\w+) \\w+([-.]\\w+)\\.\\w+([-.]\\w+)$" )!=0) { alert(" 请输入正确电子邮件" )

document.forms[0].email.select()

return false

}

return true

}

-->

< /script>

< /head>

< body>

< p>

<

java.util.date date = new java.util.date()

out.print(new java.util.date())

out.print(" < hr> " )

>

本例子是调用postmail.java来发送认证的邮件，需要下载mail.jar和activation.jar，并设置classpath

< jsp:usebean id=" mail" scope=" page" class=" mail.postmail" />

< form action=" " method=" post" onsubmit=" return checkdata()" >

< p> 请输入发件人电子邮件:< input type=" text" name=" email" >

< p> 请输入收件人电子邮件:< input type=" text" name=" toemail" >

< p> < input type=" submit" value=" 发送" >

< form>

<

string email =" " toemail=" "

if(request.getparameter(" email" )!=null){

email =request.getparameter(" email" )

}

if(request.getparameter(" toemail" )!=null){

toemail =request.getparameter(" toemail" )

}

//if(email!=null)

if( email.trim().length()> 0 & & !email.matches(" ^\\w+([-+.]\\w+) \\w+([-.]\\w+)\\.\

\w+([-.]\\w+)$" )) {

out.print(" 发件人邮件地址不正确" )

return

}

if(toemail.trim().length()> 0 & & !toemail.matches(" ^\\w+([-+.]\\w+) \\w+([-.]\\w+)\\.\\w+([-.]\\w+)$" )) {

out.print(" 收件人邮件地址不正确" )

return

}

if(email.trim().length()> 0 & & toemail.trim().length()> 0){

try{

mail.send(email toemail " test postmail.java 中文" " < h1> java mail，好 postmail!< /h1> < br> < br> < b> < /b> " )

out.print(" < font color=' green' > 邮件已发送< /font> " )

}catch(exception e){

out.print( " < font color=' red' > 出错了< /font> " )

out.print(e.getmessage())
