我一直在尝试实现以下 servlet 代码来实现电子邮件功能，但我不断收到此代码错误。请看一下...
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Properties;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.*;
import javax.servlet.RequestDispatcher;
public class email extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String to="amanmaheshwari25@gmail.com"; //emailID at which the mail is send
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
Session session=null;
try{
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 = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("cconatus.2011@gmail.com","password");//change accordingly
}
});}
catch(Exception e)
{out.println("error234");}
try {
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("ccnatus.2011@gmail.com"));//change accordingly
message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
message.setSubject("Pls find the message inside");
String dd = "hey";
message.setText(dd);
//send message
Transport.send(message);
out.println("success");
}
catch(Exception e)
{out.println("error");}
finally {
out.close();
}
}
我得到的输出是：错误，即来自最后一个catch块的错误请尽快给出一些建议。
