java - mkyong - ¿Cómo envío un correo electrónico HTML en Spring MVC?

spring mail properties

Question

He enviado correos electrónicos simples usando esto:

SimpleMailMessage mailMessage = new SimpleMailMessage();

mailMessage.setTo("[email protected]");
mailMessage.setSubject("This is the test message for testing gmail smtp server using spring mail");
mailMessage.setFrom("[email protected]");
mailMessage.setText("This is the test message for testing gmail smtp server using spring mail. /n" +
        "Thanks /n Regards /n Saurabh ");
mailSender.send(mailMessage);

Qué configuración necesito resolver para poder enviar correos electrónicos html

Answer 1

En primavera esto debería hacerse de esta manera:

Tu clase de correo electrónico:

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);
        }
    }


}

beans: (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="[email protected]" />
        <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>

Uso:

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("[email protected]",
            "[email protected]",
            "test html email",
            html);

Answer 2

No creo que la clase SimpleMailMessage tenga tales opciones.

Estoy seguro de que puede hacerlo con JavaMailSender y MimeMessagePreparator, porque necesita establecer el tipo de contenido MIME para HTML.

Vea este enlace para ayuda:

Answer 3

Puede que le interese consultar este artículo: "Correo electrónico HTML enriquecido en Spring with Thymeleaf" http://www.thymeleaf.org/doc/articles/springmail.html

Utiliza Thymeleaf como una capa de vista de plantillas, pero los conceptos y el código específico de Spring explicados allí son comunes a todas las aplicaciones de Spring.

Además, tiene una aplicación complementaria de ejemplo, cuyo código fuente puede usar como base para sus necesidades.

Saludos, Daniel.

Nivel de clase:

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);
        helper.setSubject(subject);
        result="success";
        mailSender.send(message);
    } catch (MessagingException e) {
        throw new MailParseException(e);
    }finally {
        if(result !="success"){
            result="fail";
        }
    }

    return result;

}

Nivel de XML:

    <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="********@gmail.com" />

String emailMessage = report.toString();
            Map velocityContext = new HashMap();
            velocityContext.put("firstName", "messi");
            velocityContext.put("Date",date );  
            velocityContext.put("Exception",emailMessage );
            String text = VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, "VelocityTemplate.vm","UTF-8", velocityContext);
            MimeMessage message = mailSender.createMimeMessage();
            MimeMessageHelper helper;
            helper = new MimeMessageHelper(message, true);
            helper.setTo("[email protected]");
            helper.setFrom("[email protected]");
            helper.setSubject("new email");
            helper.setText(text, true);         
            mailSender.send(message);
