Maneira simples de enviar um e-mail usando Spring MVC 5.xx Framework – org.springframework.mail. javamail.JavaMailSenderImpl

Publicados: 2018-10-23

maneira simples de enviar um e-mail usando spring-mvc-4-x-framework

Existem alguns artigos que você pode ter lido no Crunchify no Spring MVC, como Introdução ao Spring MVC Framework, Hello World Spring MVC, Upload de vários arquivos usando Spring MVC, etc.

Neste tutorial, veremos como aproveitar a biblioteca org.springframework.mail.javamail.JavaMailSenderImpl para enviar um email usando Spring MVC 5.1.3.RELEASE.

Vamos começar:

Aqui está uma estrutura final do projeto. Certifique-se de criar o arquivo de acordo.

Estrutura do projeto de envio de email do Spring MVC 4.1.x

Passo 1

Crie um projeto Maven simples CrunchifySpringMVC4SendEmailTutorial .

  • Marque a caixa de seleção para a opção “ Create a simple project (skip archetype selection) ”
  • Forneça todas as informações semelhantes ao diagrama abaixo, ou seja, ID do grupo, ID do artefato, nome e descrição que usaremos nas próximas etapas.

Criar projeto Spring MVC Maven

Passo 2

Abra o arquivo pom.xml e adicione 3 dependências.

  1. contexto de primavera
  2. spring-context-support
  3. javax.mail

Aqui está meu arquivo pom.xml completo.

Etapa 3

Crie o arquivo Spring Bean crunchify-bean.xml na pasta src/main/resources .

Os beans Spring são configurados usando a abordagem XML tradicional. No framework Spring MVC, o bean é um objeto que é instantiated , assembled e managed por um contêiner Spring IoC (Inversão de Controle).

Certifique-se de atualizar os valores dos campos de nome de username e password com seus valores reais/reais.

Passo 4

Crie a anotação CrunchifyEmailAPI.java da classe API com @Service (org.springframework.stereotype.Service) na pasta src/main/java .

@Service ( "crunchifyEmail" )
public class CrunchifyEmailAPI {
 
@Autowired
private MailSender crunchifymail ; // MailSender interface defines a strategy

public void crunchifyReadyToSendEmail ( String toAddress , String fromAddress , String subject , String msgBody ) {
 
SimpleMailMessage crunchifyMsg = new SimpleMailMessage ( ) ;
crunchifyMsg . setFrom ( fromAddress ) ;
crunchifyMsg . setTo ( toAddress ) ;
crunchifyMsg . setSubject ( subject ) ;
crunchifyMsg . setText ( msgBody ) ;
crunchifymail . send ( crunchifyMsg ) ;
}
}

Passo-5

Crie a classe de teste CrunchifyEmailTest.java na pasta src/main/java .

import org . springframework . context . support . ClassPathXmlApplicationContext ;
 
/**

public class CrunchifyEmailTest {
 
@SuppressWarnings ( "resource" )
public static void main ( String args [ ] ) {
 
// Spring Bean file you specified in /src/main/resources folder
String crunchifyConfFile = "crunchify-bean.xml" ;
ConfigurableApplicationContext context = new ClassPathXmlApplicationContext ( crunchifyConfFile ) ;
 
// @Service("crunchifyEmail") <-- same annotation you specified in CrunchifyEmailAPI.java
CrunchifyEmailAPI crunchifyEmailAPI = ( CrunchifyEmailAPI ) context . getBean ( "crunchifyEmail" ) ;
String toAddr = "[email protected]" ;
String fromAddr = "[email protected]" ;
 
// email subject
String subject = "Hey.. This email sent by Crunchify's Spring MVC Tutorial" ;
 
// email body
String body = "There you go.. You got an email.. Let's understand details on how Spring MVC works -- By Crunchify Admin" ;
crunchifyEmailAPI . crunchifyReadyToSendEmail ( toAddr , fromAddr , subject , body ) ;
}
}

Certifique-se de atualizar toAddr e fromAddr acima.

Passo-6

Agora let's run seu CrunchifyEmailTest.java e fazer o checkout do resultado do console . Também não se esqueça de fazer checkout your Gmail .

Da minha conta do Gmail:

E-mail enviado pelo framework Spring MVC 4.1.6

Saída do console:
