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.auth">true</prop>
<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).
我的目标:使用普通/文本,文本/ html和附件通过SMTP发送交易电子邮件.
我的代码:用JavaMail实现
我的问题:它在hotmail或outlook上看起来很好.但是在gmail上,如果它是带有.txt附件的电子邮件,它就不会正确显示邮件正文(如果附件是图像,它可以正常工作)
任何帮助将受到高度赞赏.
这是我的原始SMTP输出:

This is …有没有人看到JavaMail没有向SMTP服务器发送正确的MimeMessages,具体取决于JVM的启动方式？在一天结束时,我无法使用Subject:或From:字段发送JavaMail SMTP邮件,并且只有在将应用程序作为战争运行时才会显示其他标题丢失.
Web项目是使用Maven构建的,我正在测试使用浏览器和简单的mail.jsp发送JavaMail来调试并在启动应用程序时看到不同的行为:
1)mvn jetty:run(邮件发送正常,有正确的Subject和From字段)
2)mvn jetty:run-war(邮件发送正常,但缺少主题,发件人和其他字段)
我在(详细)Maven调试输出(-X)上精心运行diff,并且两者之间的运行时依赖性没有差别.我还比较了系统属性,它们是相同的.Jetty发生了其他事情:运行战争案例改变了JavaMail的行为方式.还有什么需要转动？
奇怪的是,我在两种情况下都尝试过调试器,发现javax.mail.internet.MimeMessage实例的创建方式不同.webapp使用Spring发送从Apache ActiveMQ队列中挑选的电子邮件.运行应用程序时,mvn jetty:runMimeMessage.contentStream变量用于邮件内容.运行时mvn jetty:run-war,MimeMessage.content变量用于消息内容,content = ASCIIUtility.getBytes(is); call从已解析的内容中删除所有标头数据.由于这看起来很奇怪,并且调试Spring/ActiveMQ是一个深入的研究,我创建了一个没有任何基础结构的简化测试:只使用了一个使用mail-1.4.2.jar的JSP,但缺少相同的头文件.
另外值得注意的是,在Tomcat 5.5.27下运行WAR文件时,缺少这些头文件.运行WAR时,Tomcat的行为就像Jetty一样,缺少相同的标头.
打开JavaMail调试后,我清楚地看到不同的输出.
好的案例:在jetty:run(非WAR)中,日志输出是:

byte[] pdfByteArray = JasperExportManager.exportReportToPdf(jasperPrint);

}
这是我用来构建MimeBodyPart附件的代码:
if (arrayInputStream != null && arrayInputStream instanceof ByteArrayInputStream) {
MimeBodyPart attachment = new MimeBodyPart(arrayInputStream);
attachment.setHeader("Content-Type", "application/pdf");
mimeMultipart.addBodyPart(attachment);

我确信这不是一个好的解决方案,特别是对IMAP的调查有点愚蠢,但我无法IMAP listener运行.
不是每次运行都重新创建会话可能是一个更好的解决方案,但我怎么知道何时session is closed或是否可以故意关闭它？但是没有什么Session.close()比Session或者什么更像是NULL？或者会话上有一些已定义的超时...
