通过jsp发送电子邮件

我正在尝试设计一个jsp页面,我可以在其中发送电子邮件,但是在核心java中正确运行的代码在jsp代码中使用时会给我异常.我相信我已经将我的mail.jar妥善放入了lib.

当前的jsp代码是:

<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>

                <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

                <html>
                <body>

                <%@ page import="java.util.Properties" %>               
                <%@ page import="javax.mail.Message" %>
                <%@ page import="javax.mail.MessagingException" %>
                <%@ page import="javax.mail.PasswordAuthentication" %>
                <%@ page import="javax.mail.Session" %>
                <%@ page import="javax.mail.Transport" %>
                <%@ page import="javax.mail.internet.InternetAddress" %>
                <%@ page import="javax.mail.internet.MimeMessage" %>


                <%
                Properties props = new Properties();
                        props.put("mail.smtp.host", "smtp.gmail.com");
                        props.put("mail.smtp.socketFactory.port", "465");
                        props.put("mail.smtp.socketFactory.class",
                                "javax.net.ssl.SSLSocketFactory");
                        props.put("mail.smtp.auth", "true");
                        props.put("mail.smtp.port", "465");

                 Session.getDefaultInstance(props,
                            new javax.mail.Authenticator() {
                                protected PasswordAuthentication getPasswordAuthentication() {
                                    return new PasswordAuthentication("prakash.d2222","**************");
                                }
                            });

                        try {

                            Message message = new MimeMessage(session);
                            message.setFrom(new InternetAddress("from@no-spam.com"));
                            message.setRecipients(Message.RecipientType.TO,
                                    InternetAddress.parse("prakash_d22@rediffmail.com"));
                            message.setSubject("hi");
                            message.setText("12345" +
                                    "\n\n No spam to my email, please!");

                            Transport.send(message);

                            System.out.println("Done");

                        } catch (MessagingException e) {
                            throw new RuntimeException(e);
                        }
                %>
                </body>
                </html>

而我所看到的错误是:

org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 37 in the jsp file: /pizza/page/ssl.jsp
The constructor MimeMessage(HttpSession) is undefined

正如错误消息告诉你的那样,没有MimeMessage构造函数需要HttpSession.这里是一个构造函数,需要一个javax.mail.Session,这似乎是你试图使用一个,而是一个HttpSession不是javax.mail.Session.

传递Session.getDefaultInstance()您当前正在丢弃的返回值.

Session mailSession = Session.getDefaultInstance(props,
    new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("prakash.d2222","**************");
        }
});

// ...

Message message = new MimeMessage(mailSession);
