我从这里复制代码只是为了使用Gmail SMTP服务器发送邮件。但是我得到了安全例外。一旦我成功发送了4封邮件,我就实现了目标,但后来我根据应用程序的需求对代码进行了一些更改,并且它引发了安全性异常。我确信它会起作用,但有一些问题。
这段代码有什么问题?
代码是:
package com.ibm.lims;
import java.security.Security;
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;
public class mails {
private static final String SMTP_HOST_NAME = "smtp.gmail.com";
private static final String SMTP_PORT = "465";
//private static final String emailMsgTxt = "robin borrowed a book";
//private static final String emailSubjectTxt = "online library management system notification";
private static final String emailFromAddress = "robins.lims2009@gmail.com";
private static final String SSL_FACTORY ="javax.net.ssl.SSLSocketFactory";
//private static final String[] sendTo = {"sendnearn@gmail.com","supersmartrobin@yahoo.co.in"};
public static void mailer(String[] sendTo,String emailSubjectTxt,String emailMsgTxt) throws Exception{
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
new mails().sendSSLMessage(sendTo,emailSubjectTxt,emailMsgTxt,emailFromAddress);
System.out.println("Sucessfully Sent mail to All Users");
}
public void sendSSLMessage(String[] recipients,String subject,String message,String from) throws MessagingException {
boolean debug = true;
Properties props = new Properties();
props.put("mail.smtp.host", SMTP_HOST_NAME);
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", SMTP_PORT);
props.put("mail.smtp.socketFactory.port", SMTP_PORT);
props.put("mail.smtp.socketFactory.class", SSL_FACTORY);
props.put("mail.smtp.socketFactory.fallback", "false");
Session session = Session.getDefaultInstance(props,new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("robins.lims2009@gmail.com","weakpaasword");
}
}
);
MimeMessage message1 =new MimeMessage(session);
message1.setFrom(new InternetAddress(from));
for(int i=0;i<=recipients.length;i++){
message1.addRecipient(Message.RecipientType.TO,new InternetAddress(recipients[i]));
}
message1.setSubject(subject);
// Create the message part.
MimeBodyPart messageBodyPart =new MimeBodyPart();
//Fill message.
messageBodyPart.setText(message);
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
// Part two is attachment.
// Put parts in message
message1.setContent(multipart);
// Send the message
Transport.send( message1 );
}
}
我曾经把它称为JSP:
<%
String requestedopration = request.getParameter("operation");
if("Borrow".equalsIgnoreCase(requestedopration)){
Borrow borrow = new Borrow();
borrow.setBook_id(request.getParameter("bookid"));
borrow.setUser_id((String)session.getAttribute("userid"));
boolean c=LimsHandler.getInstance().borrowbook(borrow);
if(c){
final String[] sendTo = {"sendnearn@gmail.com","supersmartrobin@yahoo.co.in"};
mails.mailer(sendTo,"lims notification","robin borrowed a book");
%>
但是我得到安全例外。我得到例外:

从JDK 1.4.0开始,您不需要指定SSL提供程序,因为它已内置到JDK中。 看一下Sun的explanation以及如何通过JavaMail使用GMail的例子:
答案 1 :(得分:0)
看起来您没有为ssl设置邮件传输协议。尝试添加props.put(“mail.transport.protocol”,“smtps”);.根据JavaMail站点的这个片段,您可能还需要添加“mail.smtps.auth”,“true”。
String host = "smtp.gmail.com;
String username = "user";
String password = "passwd";
Properties props = new Properties();
props.put("mail.smtps.auth", "true");
// ...
MimeMessage msg = new MimeMessage(session);
// set the message content here
Transport t = session.getTransport("smtps");
try {
t.connect(host, username, password);
t.sendMessage(msg, msg.getAllRecipients());
} finally {
t.close();
}
是的,方法不同,但使用了相同的属性。

您的代码似乎没问题,只是循环错误。使用“&lt;”而不是“&lt; =”那么你就不会得到ArrayIndexOutOfBoundException。
for (int i = 0; i < recipients.length; i++) {
message1.addRecipient(Message.RecipientType.TO,
new InternetAddress(recipients[i]));
}
