java - greenmail 服务器收不到邮件

Question

• 我的通过 Greenmail 发送电子邮件的类(class)单元测试

  公共(public)类 GreenMailTest {

  private GreenMail greenMail;
  private EmailServiceImpl emailService = new EmailServiceImpl();
  
  private MessageTemplateService messageTemplateService;
  
  private EmailProperties emailProperties;
  
  private Properties props;
  
   private static final String USER_PASSWORD = "abcdef123";
      private static final String USER_NAME = "hascode";
      private static final String EMAIL_USER_ADDRESS = "hascode@localhost";
      private static final String EMAIL_TO = "someone@localhost.com";
      private static final String EMAIL_SUBJECT = "Test E-Mail";
      private static final String EMAIL_TEXT = "This is a test e-mail.";
      private static final String LOCALHOST = "localhost";
     // private GreenMail mailServer;
  
  
  @Before
  public void testSmtpInit() {
      //ServerSetup setup = new ServerSetup();
      greenMail = new GreenMail(ServerSetupTest.SMTP);
      greenMail.start();
      messageTemplateService = mock(MessageTemplateService.class);
      emailProperties = mock(EmailProperties.class);
      emailService.setEmailProperties(emailProperties);
  }
  
  @Test
  public void testEmail() throws InterruptedException, IOException {
  
      greenMail.setUser(EMAIL_USER_ADDRESS, USER_NAME, USER_PASSWORD);
  
          // create the javax.mail stack with session, message and transport ..
          Properties props = System.getProperties();
          props.put("mail.smtp.host", LOCALHOST);
          props.put("mail.smtp.auth", "true");
          props.put("mail.smtp.port", ServerSetupTest.SMTP.getPort());
          Session session = Session.getInstance(props, null);
          Message msg = new MimeMessage(session);
          try {
              msg.setFrom(new InternetAddress(EMAIL_TO));
               msg.setRecipients(Message.RecipientType.TO,
                          InternetAddress.parse(EMAIL_USER_ADDRESS, false));
                          msg.setSubject(EMAIL_SUBJECT);
                          msg.setText(EMAIL_TEXT);
                          msg.setSentDate(new Date());
                          Transport t =  session.getTransport("smtp");
                          t.connect(EMAIL_USER_ADDRESS, USER_PASSWORD);
                          t.sendMessage(msg, msg.getAllRecipients());
                         // assertEquals("250 OK\n", t.getLastServerResponse());
                          t.close();
          } catch (MessagingException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          }
  
  
  
  
  
      // fetch messages from server
      MimeMessage[] messages = greenMail.getReceivedMessages();
  

• 我使用这段代码在 junit 上测试电子邮件服务器。

• 但是服务器没有返回任何消息

• 我做错了什么。

• 我改了代码请审核

GreenMail 在本地主机上运行。相应地调整您的 smtp 主机:

props.put("mail.smtp.host", "localhost");
