这是例子。不要忘记在类路径中添加javax.mail。
import javax.mail.*;
import javax.mail.search.FlagTerm;
import java.util.*;
public class GmailFetch {
public static void main( String[] args ) throws Exception {
Session session = Session.getDefaultInstance(new Properties( ));
Store store = session.getStore("imaps");
store.connect("imap.googlemail.com", 993, "username@gmail.com", "password");
Folder in@R_458_2419@ = store.getFolder( "IN@R_458_2419@" );
in@R_458_2419@.open( Folder.READ_ONLY );
// Fetch unseen messages from in@R_458_2419@ folder
Message[] messages = in@R_458_2419@.search(
new FlagTerm(new Flags(Flags.Flag.SEEN), false));
// Sort messages from recent to oldest
Arrays.sort( messages, ( m1, m2 ) -> {
try {
return m2.getSentDate().compareTo( m1.getSentDate() );
} catch ( MessagingException e ) {
throw new RuntimeException( e );
}
} );
for ( Message message : messages ) {
System.out.println(
"sendDate: " + message.getSentDate()
+ " subject:" + message.getSubject() );
}
}
}
