JavaMailSenderImpl 不使用邮件 session 中的 "mail.from"属性

Question

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

Java 的 MimeMessage#setFrom方法支持该功能:

Set the RFC 822 "From" header field using the value of the InternetAddress.getLocalAddress method.

但是JavaMailSenderImpl不使用该属性。

Tomcat 的 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 的 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);
    }
}

该邮件没有 From header 。

我的代码有什么问题吗？为什么 Spring 不使用邮件 session 中的 From header ？

Answer 1

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

SimpleMailMessage is more or less the least common denominator of COS' and JavaMail's mail sending capabilities. Actually, it should be possible to set the date header with COS too; it's just that there is no explicit method for it in the COS MailMessage class. So we might provide date header support for SimpleMailMessage in a future point release.

For the time being, you'll have to work with the JavaMailSender interface and JavaMail's MimeMessage class. With the MimeMessageHelper class that Spring provides, it should be easy enough to populate a MimeMessage in a SimpleMailMessage-style fashion. (See MimeMessageHelper's javadoc for details.) Of course, MimeMessage is much more powerful: It supports attachements, text encoding, etc.

我搜索并找到了那些。您尝试哪一个:

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");
