(入門SpringBoot)SpringBoot發送郵件(十一)

SpringBoot配置郵件服務:

1.引入jar

 

<!-- 郵件 -->

 

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

2.配置資源文件,郵箱參數:

#郵件:郵件服務器
spring.mail.host=smtp.163.com
#發件人郵箱
spring.mail.username=xxx@163.com
#受權碼:
spring.mail.password=abc123
#編碼:
spring.mail.default-encoding=UTF-8

3.準備發送郵件方法:

service層讀取配置文件參數,注入JavaMailSender

@Value("${spring.mail.username}")
private String sender; //讀取配置文件中的參數
@Autowired
private JavaMailSender mailSender; //自動注入的Bean

 

/**
 * 發送普通文本:
 * @param to 發送人:
 * @param subject 發送標題:
 * @param context  發送內容:
 */
@Override
public void sendSimpleMail(String to, String subject, String context) {
    SimpleMailMessage message = new SimpleMailMessage();
    message.setFrom(sender);
    message.setTo(to);
   message.setSubject(subject);
   message.setText(context);
   mailSender.send(message);

}

/**
 * 發送html:
 * @param to 發送人:
 * @param subject 發送標題:
 * @param context  發送內容:
 */
@Override
public void sendSimpleMailHTML(String to, String subject, String context) {
    MimeMessage message = null;
    try {
        message = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(message, true);
        helper.setFrom(sender);
        helper.setTo(to);
        helper.setSubject("標題：發送Html內容");

        StringBuffer sb = new StringBuffer();
        sb.append("<h1>大標題-h1</h1>")
                .append("<p style='color:#F00'>紅色字</p>")
                .append("<p style='text-align:right'>右對齊</p>");
        helper.setText(sb.toString(), true);
    } catch (Exception e) {
        e.printStackTrace();
    }
    mailSender.send(message);
}
