Question

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，从日志我可以看到内容类型设置为：

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?

我正在开发此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>
            <prop key="mail.mime.charset">UTF-8</prop>
            <prop key="mail.smtp.isSecure">true</prop>
            <prop key="mail.smtp.requiresAuthentication">true</prop>
            <prop key="mail.smtp.auth">true</prop>
            <prop key="mail.smtp.port">465</prop>
            <prop key="mail.smtp.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
            <prop key="mail.smtp.socketFactory.fallback">false</prop>
            <prop key="mail.smtp.starttls.enable">true</prop>
            <prop key="mail.debug">true</prop>
        </props>
    </property>
</bean>

<bean id="velocityEngine"
        class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="velocityProperties">
        <value>
            resource.loader=class
                class.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
        </value>
    </property>
</bean>

以下是来自邮件管理员的代码：

private void sendConfirmationEmail(final User user, final int requestId) {
        MimeMessagePreparator preparator = new MimeMessagePreparator() {
            public void prepare(MimeMessage mimeMessage) throws Exception {
                MimeMessageHelper message = new MimeMessageHelper(mimeMessage);
                message.setTo(user.getEmailAddress());
                message.setFrom(from);
                message.setSubject(subject);

                Map<String, Object> model = new HashMap<String, Object>();
                model.put("user", user);
                model.put("authorizationAddress", authorizationAddress);
                model.put("requestId", requestId);
                String text = VelocityEngineUtils
                        .mergeTemplateIntoString(
                                velocityEngine,
                                "com/mypackage/mail/registration-confirmation.vm",
                                model);
                message.setText(text, true);
            }
        };
        PendingMail pendingMail = new PendingMail(preparator);
        pool.submit(pendingMail);

    }
private class PendingMail implements Callable<Object> {
                MimeMessagePreparator preparator;

        protected PendingMail(MimeMessagePreparator preparator) {
            this.preparator = preparator;
        }

        public Object call() {
            mailSender.send(preparator);
            return null;
            }
}

你还有其他建议吗？

Answer 1

我解决了我的问题 this post

根据帖子我把它放在mailSender bean配置中：

<property name="defaultEncoding" value="UTF-8"/>

Answer 2

您可以在JavaMailSenderImpl spring bean配置中将其设置为属性mail.mime.charset。请参阅此previous query回答的示例。

Answer 3

2020年的答案，因为现在很少使用XML配置：

JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.getJavaMailProperties().put("mail.mime.charset", "UTF-8");

Answer 4

另一个选择可能是：

JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
mailSender.setDefaultEncoding("UTF-8");
