1. 配置郵件傳送器

@bean
public MailSender mailSender(Envvironment env){
    //java郵件傳送器
    JavaMailSenderImpl mailSender = new JavaMailSenderImpl();
    //設定傳送主機
    mailSender.setHost(env.getPorperty("mailserver.host"));
    //設定傳送埠號預設為25
    mailSender.setPort(env.getPorperty("mailserver.port"));
    //設定使用者名稱
 

    mailSender.setUsername(env.getPorperty("mailserver.username"));
    //設定密碼
    mailSender.setPassword(env.getPorperty("mailserver.password"));
}

2. 裝配和使用郵件傳送器

//使用Spring的MailSender傳送mail

@Autowired
private MailSender  mailSender;

public void sendSimpleSpittleMail(String to , Spittle spittle){
    SimpleMailMessage message = new
 
 SimpleMailMessage();
    String spitterName = spittle.getspittle().getFullName();
    message.setFrom("[email protected]");
    message.setTo(to);
    message.setSubject("New splittle from" + spitterName);
    message.setText(spitterName + "say" + spittle.getText);
    mailSender.send(message);
}
//setFrom指定郵件的傳送者
 

//setTo指定郵件的接收者
//setSubject設定郵件的主題
//setText設定郵件的具體內容
//send傳送郵件
