學習SpringBoot 集成郵件發送(參考純潔的微笑) 記錄其中遇到的問題

1.pom裏面，增長相關依賴包

<!--郵件集成-->
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

2.application.properties裏面，增長相關配置

#郵箱服務器地址
#spring.mail.host=smtp.qiye.163.com
spring.mail.host=smtp.163.com
#用戶名
spring.mail.username=**********
#密碼
spring.mail.password=********
spring.mail.default-encoding=UTF-8
spring.mail.port=25
#/以誰來發送郵件
mail.fromMail.addr=********

須要注意 

設置開啓本身郵箱對應的服務

username與addr保持一致   

password不是郵箱的登陸名，而是客戶端的受權碼

3.貼上代碼

package com.example.demo.emilyServer;

        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

    /**

    public void sendMailByImage(String to, String subject, String content, String filePath,String image){
        MimeMessage message = javaMailSender.createMimeMessage();
        try {

            helper.setSubject(subject);
            helper.setText(content);
            helper.setTo(to);
            helper.setFrom(from);

            helper.addAttachment("測試文檔.docx",file);
            helper.addInline("測試圖片",new File(image));
            javaMailSender.send(message);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }

發送附件，郵件的時候，若是不成功，參看163的返回碼查找緣由

請勿有test等，會被當作垃圾郵件處理
