如何在Spring MVC中发送HTML电子邮件？

Question

我已成功发送简单的电子邮件:

SimpleMailMessage mailMessage = new SimpleMailMessage();

mailMessage.setTo("someone@abc.com");
mailMessage.setSubject("This is the test message for testing gmail smtp server using spring mail");
mailMessage.setFrom("abc@gmail.com");
mailMessage.setText("This is the test message for testing gmail smtp server using spring mail. \n" +
        "Thanks \n Regards \n Saurabh ");
mailSender.send(mailMessage);

我需要什么设置才能发送html电子邮件

Answer 1

import javax.mail.internet.MimeMessage;
import org.springframework.mail.javamail.MimeMessageHelper;

MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, "utf-8");
String htmlMsg = "<h3>Hello World!</h3>";
//mimeMessage.setContent(htmlMsg, "text/html"); /** Use this or below line **/
helper.setText(htmlMsg, true); // Use this or above line.
helper.setTo("someone@abc.com");
helper.setSubject("This is the test message for testing gmail smtp server using spring mail");
helper.setFrom("abc@gmail.com");
mailSender.send(mimeMessage);

Answer 2

我不认为SimpleMailMessage类有这样的选项.

我确信您可以使用JavaMailSender和MimeMessagePreparator来完成它,因为您需要为HTML设置MIME内容类型.

在Spring中,这应该以这种方式完成:

您的电子邮件类:

import java.util.logging.Level;
import java.util.logging.Logger;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

public class HTMLMail
{
    private JavaMailSender mailSender;


    public void setMailSender(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }

    public void sendMail(String from, String to, String subject, String msg) {
        try {

            MimeMessage message = mailSender.createMimeMessage();

            message.setSubject(subject);
            MimeMessageHelper helper;
            helper = new MimeMessageHelper(message, true);
            helper.setFrom(from);
            helper.setTo(to);
            helper.setText(msg, true);
            mailSender.send(message);
        } catch (MessagingException ex) {
            Logger.getLogger(HTMLMail.class.getName()).log(Level.SEVERE, null, ex);
        }
    }


}

bean:(Spring-Mail.xml)

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="smtp.gmail.com" />
        <property name="port" value="587" />
        <property name="username" value="youremail@gmail.com" />
        <property name="password" value="yourpassword" />

        <property name="javaMailProperties">
            <props>
                <prop key="mail.smtp.auth">true</prop>
                <prop key="mail.smtp.starttls.enable">true</prop>
            </props>
        </property>
    </bean>
    <bean id="htmlMail" class="com.mohi.common.HTMLMail">
        <property name="mailSender" ref="mailSender" />
    </bean>
</beans>

用法:

ApplicationContext context = new ClassPathXmlApplicationContext("Spring-Mail.xml");

        HTMLMail mm = (HTMLMail) context.getBean("htmlMail");
        String html="<p>Hi!</p><a href=\"google.com\">Link text</a>";
    mm.sendMail("sender@gmail.com",
            "receiver@gmail.com",
            "test html email",
            html);

您可能有兴趣查看这篇文章:"Thymeleaf Spring中的丰富HTML电子邮件" http://www.thymeleaf.org/doc/articles/springmail.html

它使用Thymeleaf作为模板视图层,但是所解释的概念和特定于Spring的代码对所有Spring应用程序都是通用的.

此外,它还有一个配套的示例应用程序,可以使用源代码作为您需求的基础.

问候,丹尼尔.

班级：

public String sendEmailToUsers(String emailId,String subject, String name){
    String result =null;
    MimeMessage message =mailSender.createMimeMessage();
    try {

        MimeMessageHelper helper = new MimeMessageHelper(message, false, "utf-8");
        String htmlMsg = "<body style='border:2px solid black'>"
                    +"Your onetime password for registration is  " 
                        + "Please use this OTP to complete your new user registration."+
                          "OTP is confidential, do not share this  with anyone.</body>";
        message.setContent(htmlMsg, "text/html");
        helper.setTo(emailId);
