I read on several sites that, when using the JavaMail API, to set the property mail.smtp.ssl.enable to true. I have some code as follows:
props.put("mail.smtp.host", "exchangemail1.example.com");
props.put("mail.from", "myemail@example.com");
props.put("mail.smtp.starttls.enable", "true");
// I tried this by itself and also together with ssl.enable)
props.put("mail.smtp.ssl.enable", "true");
Session session = Session.getInstance(props, null);
MimeMessage msg = new MimeMessage(session);
msg.setFrom();
msg.setRecipients(Message.RecipientType.TO, "me.at@example.com");
// also tried @gmail.com
msg.setSubject("JavaMail ssl test");
msg.setSentDate(new Date());
msg.setText("Hello, world!\n");
props.put("mail.smtp.auth", "false");
Transport trnsport;
trnsport = session.getTransport("smtp");
trnsport.connect();
msg.saveChanges();
trnsport.sendMessage(msg, msg.getAllRecipients());
trnsport.close();

问题来自主题.我正在使用Spring 3.0.3.RELEASE和velocity 1.6.4中的JavaMailSenderImpl从模板进行邮件准备.
当我从我的webapp收件人发送带有克罗地亚字符的电子邮件时收到"？" 在正常的克罗地亚人的立场.如果我为邮件调试调试模式,从日志中我可以看到Content-type设置为:
Content-Type: text/html; charset=us-ascii
Content-Transfer-Encoding: 7bit
如何将其设置为:
Content-Type: text/html; charset=utf-8?
我正在开发这个webapp时使用gmail进行邮件发送.
以下是我在spring的servlet xml conf文件中的设置:
<bean id="userAuthorizationManager" class="com.mypackage.manage.SimpleUserAuthorizationManagerImpl">
<property name="mailSender" ref="mailSender" />
<property name="velocityEngine" ref="velocityEngine" />
<property name="from" value="address" />
<property name="authorizationAddress" value="some text" />
<property name="subject" value="some text" />
</bean>
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.gmail.com" />
<property name="port" value="465" />
<property name="username" value="user" />
<property name="password" value="pass" />
<property name="protocol" value="smtps" />
<property name="javaMailProperties">
<props>

<prop key="mail.smtp.connectiontimeout">5000</prop>
<prop key="mail.smtp.sendpartial">true</prop>
<prop key="mail.smtp.userset">true</prop> …JavaMail是否支持通过服务器推送通知新电子邮件？
如果是,那么该文件在哪里？如果没有,是否有可以执行此操作的库？
我正在尝试使用Glassfish 3.1提供的jar文件在Java EE 6中使用JavaMail设置简单的日志记录测试.关于这个问题似乎有很多问题,但我还没有找到任何有帮助的答案.我的测试代码如下所示:
import java.util.logging.Logger;
public class MyClass {
private static final Logger LOGGER = Logger.getLogger("MyClass");
public static void main(String[] args) {
LOGGER.severe("This is a test");
}
}
我的logging.properties文件包含以下内容:
com.sun.mail.util.logging.MailHandler.mail.smtp.host={my mail hub FQDN}
com.sun.mail.util.logging.MailHandler.mail.smtp.port=25
com.sun.mail.util.logging.MailHandler.mail.to={me}
com.sun.mail.util.logging.MailHandler.mail.from={support address}
com.sun.mail.util.logging.MailHandler.level=WARNING
com.sun.mail.util.logging.MailHandler.verify=local
com.sun.mail.util.logging.MailHandler.subject=Application Error
com.sun.mail.util.logging.MailHandler.formatter=java.util.logging.SimpleFormatter
我使用以下方法构建类:
javac -cp $AS_INSTALL/glassfish/modules/javax.mail.jar:$AS_INSTALL/install/lib/external/jaxb/activation.jar:. MyClass.java
然后我运行程序使用:
java -cp $AS_INSTALL/glassfish/modules/javax.mail.jar:$AS_INSTALL/install/lib/external/jaxb/activation.jar:. -Djava.util.logging.config.file=logging.properties MyClass
这会导致以下错误:
Sep 22, 2011 4:19:25 PM MyClass main
SEVERE: This is a test
java.util.logging.ErrorManager: 3: SEVERE: no object DCH for MIME type multipart/mixed;

javax.activation.UnsupportedDataTypeException: no …我正在阅读来自emailServer的电子邮件并将其保存在数据库中.我正在使用以下代码从电子邮件服务器上的文件夹("INBOX")中读取邮件并检索与其对应的邮件但我得到了
"java.lang.ArrayIndexOutOfBoundsException: message number (621) out of bounds (620)
at com.sun.mail.imap.MessageCache.getMessage(MessageCache.java:123)
at com.sun.mail.imap.MessageCache.getMessageBySeqnum(MessageCache.java:153)
at com.sun.mail.imap.IMAPFolder.getMessageBySeqNumber(IMAPFolder.java:2795)
at com.sun.mail.imap.IMAPFolder.getMessagesByUID(IMAPFolder.java:1924)"
我正在使用javax.mail.1.4.4,这个问题主要是在收件箱被淹没时出现的.
使用的代码:
folder = store.getFolder("INBOX");
folder.open(Folder.READ_WRITE);
// messageUID is uid of last message I saved in DB
Message messages[] = ((UIDFolder) folder).getMessagesByUID(messageUID + 1, UIDFolder.LASTUID);
我做了一些研究,发现一旦打开就为文件夹设置了messagecache,我们假设它被设置为520(文件夹的大小).如果在设置了消息缓存后到达任何消息,则在最后一个消息序列中,num超过了消息缓存的总大小,并引发异常.
任何人都可以让我知道如何获取文件夹中最后一条消息的UId的绝对值或如何获取文件夹锁定,以便在设置缓存后,文件夹不会更新文件夹的大小.
我正在使用Java Mail API,我正在尝试通过Gmail的SMTP发送电子邮件.我的程序如何工作:java.util.Scanner类用于获取用户输入 - 我要求用户在邮件发送类中使用各种参数; 执行以下操作:
Message mailMessage = new MimeMessage(session);
mailMessage.setFrom(new InternetAddress("example@example.com"));
mailMessage.setRecipients(Message.RecipientType.TO,InternetAddress.parse(mail.getTo()));
mailMessage.setSubject(mail.getSubject());
mailMessage.setText(mail.getMessage());
Transport.send(mailMessage);
只要我使用ASCII符号/字符,一切都有效.但每当我想使用"特定国家"字符时 - 比如[õäöü] - 我会看到一堆奇怪的符号......
到目前为止我使用的技术(对我来说不起作用):
setHeader("Content-Type", "text/plain; charset=UTF-8");
setHeader("Content-Encoding","ISO-8859-9");
setContent(message, "text/plain; charset=iso-8859-2");
注意:执行System.out.println()以显示要发送的消息时,IDE中的所有内容都会正确显示.
编辑:ex发送邮件正文时[õäöü]它在Gmail中显示[ä""？].
编辑:何时mailMessage.setText(MimeUtility.encodeText(mail.getMessage(), "UTF-8", "Q"));使用,然后Gmail中的输出如下:
"=?UTF-8?Q?=C3=A4=E2=80=9E=E2=80=9D=EF=BF=BD;=0D=0A?="
另一个编辑:有趣的是,当我这样做时:mailMessage.setText(strVar + "õäöü", "ISO-8859-1");
它实际上在我的电子邮件中很好地附加了"õäöü"(但字符串的第一部分[strVar]仍然充满了？和[]的).
我试图从spring应用程序发送邮件.我已经包含了所有jar文件,但是它显示了这个异常:
