存在session问题：
Session session = Session.getDefaultInstance(properties, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(account, password);
}
});
第二种：
Session session = Session.getInstance(properties, new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(account, password);
}
});
session.setDebug(true);
return session;
}
Expand knowledge:
Problem solving,
the Session session = Session.getDefaultInstance (props, myauth );
changed
Session session = Session.getInstance (props, myauth );
can
I follow his method to replace the code in the method a bit, re-run, enter the first email account and password, successfully sent, a second input other email account and password, send a point, ok, successful.
Well, problem solved here, but do not understand Session.getDefaultInstance and Session.getInstance What difference does it make? And looking at the statistics, the results also found 553 anomalies encountered people who write a blog, is actually the title of his blog:
"JavaMail in Session.getDefaultInstance application",
is not it, so difficult to find, general is the name of the search problem, who will search this. If the poster can change the title of the problem, then I will not have to look so on the. But still would like to thank this man, he explains in detail why the method used Session.getDefaultInstance will appear when you enter other email account to log the second occurrence of abnormality in this post 553.
The following are this excerpt from this post:
http://muder2007.blog.163.com/blog/static/45933070200872025130613/
What getDefaultInstance?
As can be seen from the process flow, first from the cache if there are properties exist
if present, the default properties are loaded
If there is only load properties defined by the user,
so when a separate application for each user in order to create properties , or should call the getInstance,
unless you want to have a default properties allow users to use
Found the problem, because it will first go to memory and system files to look for properties, so no matter what I change the data in the page a few times, and in fact the same as when the system starts generating the session in the background, so MailUtil.sendTextMessage (mailSession , RptTaskMailConfig.Sender,
Receiver, null, mail_subject, mail_content, "GB2312", null); inconsistent session where the sender and the incoming sender, therefore the error, modify Session.getDefaultInstance (props, authentic); as Session.getInstance ( props, authentic); later, you can modify the message after sending the correct account number, password and other information .OK
Finally, add the difference session.getdefaultinstance and getinstance of:
If you want to use both accounts to send javamail, such as the use [email protected] 1 # send e-mail, use the Send [email protected] 2 #-mail, this time, you will need to create two objects simultaneously java.mail.Session . But if you are still using Session.getDefaultInstance create session objects, you will find that the second username: session [email protected] created and always like the first, this is why? Because, getDefaultInstance is truly a singleton, and, inside the username and password properties are final type can not be changed. So, you will find two email is sent by the [email protected] come. So this time you want to use javax.mail.Session.getInstance () method to create a session object.
