Question

我想发送一封带有From标题的邮件，但我不想在SimpleMailMessage中设置From标题。我想使用mail.from的javax.mail.Session属性配置的默认值（在context.xml中定义）。

Java的MimeMessage#setFrom方法支持该功能：

设置RFC 822＆＃34; From＆＃34;标头字段使用InternetAddress.getLocalAddress方法的值。

但JavaMailSenderImpl并未使用该属性。

Tomcat＆＃39; context.xml：

<Resource name="mail" type="javax.mail.Session" mail.debug="true"
        mail.smtp.host="mail.mycompany.com" mail.from="no-reply@mycompany.com"/>

Spring beans.xml：

<bean id="mailSession" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/mail" />
</bean>

<bean id="JavaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="session" ref="mailSession" />
</bean>

我的服务：

@Named
public class MailService {

    @Inject
    private JavaMailSender javaMailSender;

    public void send() {

        SimpleMailMessage message = new SimpleMailMessage();
        message.setTo("customer@company.com");
        message.setSubject("Test");
        message.setText("Test message body");

        javaMailSender().send(message);
    }
}

邮件没有From标头。

我的代码有什么问题吗？为什么Spring不使用邮件会话中的From标头？

Answer 1

从此链接：http://springframework-user.narkive.com/wbF105Ma/simplemailmessage-and-date-header

SimpleMailMessage或多或少是COS'和JavaMail邮件发送功能的最小公分母。实际上，应该可以用COS设置日期标题;它只是在COS MailMessage类中没有明确的方法。因此，我们可能会在以后的版本中为SimpleMailMessage提供日期标头支持。

目前，您必须使用JavaMailSender接口和JavaMail的MimeMessage类。使用Spring提供的MimeMessageHelper类，应该很容易以SimpleMailMessage样式的方式填充MimeMessage。（有关详细信息，请参阅MimeMessageHelper的javadoc。）当然，MimeMessage功能更强大：它支持附件，文本编码等。

我搜索并找到了那些。你尝试哪一个：

1：

MimeMessage mimeMessage = //get message from wherever
mimeMessage.addHeader("From", "me@mail.com");

2：

MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true, "UTF-8");
 message.setFrom("me@mail.com");

JavaMailSenderImpl没有使用＆＃34; mail.from＆＃34;来自邮件会话的财产
