文章标签 java qq邮箱配置 html java jar包 文章分类 Java 后端开发

实现邮件收发功能需要3个jar包：

1.JavaMail组件保内的mail.jar和smtp.jar包

2.JAF组件包里的activition.jar。

复制到WebRoot/WEB-INF/lib目录下。

一、编写index.jsp页面，具体代码如下：

1 <%@ page language="java" contentType="text/html; charset=gb2312"
 2     pageEncoding="gb2312"%>
 3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 4 <html>
 5 <head>
 6 <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
 7 <title>welcome</title>
 8 </head>
 9 <body>
10      <form action="sendMail.jsp" method="post" name="form1">
11        <table width="75" border="0" align="center" cellspacing="1"
12               bgcolor="#006600" class="black">
13               <tr bgcolor="#ffffff">
14                   <td width="24%">收信人地址：</td>
15                   <td width="76%"><input name="to" type="text" id="to"></td>
16               </tr>
17               <tr bgcolor="#ffffff">
18                   <td >主题：</td>
19                   <td ><input name="title" type="text" id="title"></td>
20               </tr>
21               <tr>
22               <td height="18" colspan="2" bgcolor="#ffffff">
23                                                   信件类型
24                 <select name="emailtype" id="emailtype">
25                    <option value="text/plain" selected>Text</option>
26                    <option value="text/html" selected>Html</option>
27                 </select>
28               </td>
29               </tr>
30               <tr>
31                   <td height="53" colspan="2" bgcolor="#ffffff">
32                      <textarea rows="5" cols="50" name="content" id="content"></textarea>
33                   </td>
34               </tr>
35               <tr align="center">
36                    <td colspan="2" bgcolor="#ffffff">
37                                                                               附件1（自定义）：
38                        <input name="fj1" type="text" id="fj1">
39                        (输入文本信息)      
40                    </td>
41               </tr>
42               <tr align="center" valign="bottom">
43                    <td colspan="2" bgcolor="#ffffff">
44                                                                               附件2（本地）：
45                        <input name="fj2" type="file" id="fj2" size="10">      
46                    </td>
47               </tr>
48                <tr align="center" >
49                    <td colspan="2" bgcolor="#ffffff">
50                                                                               附件3（远程）：
51                        <input name="fj3" type="text" id="fj3" value="http://">
52                        (输入URL)      
53                    </td>
54               </tr>
55               <tr align="center" >
56                    <td colspan="2" bgcolor="#ffffff">
57                                                                               
58                        <input name="submit" type="submit"  value="发送">
59                          <input name="submit2" type="reset"  value="重置">
60                    </td>
61               </tr>
62        </table>
63      </form>
64 </body>
65 </html>

二、创建sendMail.jsp页面，具体代码如下：

<%@ page language="java" contentType="text/html; charset=gb2312"
    pageEncoding="gb2312"%>
<%request.setCharacterEncoding("gb2312"); %>
<%@ page import="java.util.*,javax.mail.*" %>
<%@ page import="javax.mail.internet.*"%>
<%@ page import="javax.activation.*" %>
<%@ page import="java.net.*" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>Insert title here</title>
</head>
<body>
<%
  try{ 
	 String tto=request.getParameter("to");
	 String ttitle=request.getParameter("title");
	 String emailtype=request.getParameter("emailtype");
	 String tcontent=request.getParameter("content");
	 String tfj1=request.getParameter("fj1");
	 String tfj2=request.getParameter("fj2");
	 String tfj3=request.getParameter("fj3");
	 //声明properities存储发件服务器信息
	 Properties props=new Properties();
	 props.put("mail.smtp.host", "smtp.qq.com");
	 props.put("mail.smtp.auth", "true");
	 //创建邮件回话
	 Session s=Session.getInstance(props);
	 s.setDebug(true);
     //创建一个消息对象
     MimeMessage message=new MimeMessage(s);
     InternetAddress from=new InternetAddress("393743083@qq.com");
     message.setFrom(from);
     InternetAddress to=new InternetAddress(tto);
     message.setRecipient(Message.RecipientType.TO, to);
     message.setSubject(ttitle);
     message.setSentDate(new Date());
     Multipart mm = new MimeMultipart();
     BodyPart mdp=new MimeBodyPart();
     mdp.setContent(tcontent, emailtype+";charset=gb2312");
     mm.addBodyPart(mdp);
     //附件1
     mdp=new MimeBodyPart();
     DataHandler dh=new DataHandler(tfj1,"text/plain;charset=gb2312");
     mdp.setFileName("text.txt");
     mdp.setDataHandler(dh);
     mm.addBodyPart(mdp);
     //附件2
    mdp=new MimeBodyPart();
     FileDataSource fds=new FileDataSource(tfj2);
     dh=new DataHandler(fds);
     int ddd=tfj2.lastIndexOf("\\");
     String fname=tfj2.substring(ddd);
     String ffname=new String(fname.getBytes("gb2312"),"ISO8859-1");
     mdp.setFileName(ffname);
     mdp.setDataHandler(dh);
     mm.addBodyPart(mdp);
     //附件3
    mdp=new MimeBodyPart();
    URL urlfj=new URL(tfj3);
    URLDataSource ur=new URLDataSource(urlfj);
    dh=new DataHandler(ur);
    int ttt=tfj3.lastIndexOf("/");
    String urlname=tfj3.substring(ttt);
    mdp.setFileName(urlname);
    mdp.setDataHandler(dh);
    mm.addBodyPart(mdp);
    message.setContent(mm);
    message.saveChanges();
    //发送邮件
    Transport transport=s.getTransport("smtp");
    transport.connect("smtp.qq.com",用户名,密码);
    transport.sendMessage(message, message.getAllRecipients());
    transport.close();
 %>
   <div align="center">
       <p><font color="#ff6600">发送成功</font></p>
       <br>
       <a href="sendMail.jsp">再来一封</a>
   </div>
   <%
  }catch(MessagingException e){   
       out.println(e.toString());
  }
   %>
</body>
</html>

　　注：腾讯邮箱需要开通smtp功能。
