springboot集成email

【一】準備工作

• 準備163郵箱
  https://mail.163.com/
  註冊賬號用於發送郵件
• 配置smtp郵件服務
  
  
  
  配置好授權碼，這個很重要，在後面的使用過程中會使用到

【二】添加依賴

  <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
            <version>2.2.2.RELEASE</version>
   </dependency>

【三】yml配置

#===== Email settings 郵件發送的配置=====#
#郵箱服務器地址
spring:
  mail:
    host: smtp.163.com
    username: [email protected]
    password: xxxxxx   #這個地方是授權碼，不是登錄密碼
    default-encoding: UTF-8

【四】發送郵件

package com.feng.email.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;

/**

 */
@RestController
@RequestMapping("email")
public class EmailController {

    @Autowired
    private JavaMailSender mailSender;

    /**
     * 發送簡單文本郵件
     * @param to
     * @param subject
     * @param content
     * @return
     */
    @GetMapping("send")
    public String sendSimpleMail(String to, String subject, String content) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom("[email protected]");
        message.setTo("[email protected]");
        message.setSubject("test");
        message.setText("this springboot email");
        mailSender.send(message);
        return "發送成功";
    }

    /**
     * 發送複雜郵件+鏈接
     * @return
     * @throws MessagingException
     */
    @GetMapping("send2")
    public String sendAttachmentMail() throws MessagingException {

        MimeMessage mimeMailMessage = null;

        mimeMailMessage = mailSender.createMimeMessage();
        //true 表示需要創建一個multipart message
        MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMailMessage, true);
        mimeMessageHelper.setFrom("[email protected]");
        mimeMessageHelper.setTo("[email protected]");
        mimeMessageHelper.setSubject("複雜郵件");
        mimeMessageHelper.setText("帶有圖片的郵件");
        //文件路徑 目前寫死在代碼中，之後可以當參數傳過來，或者在MailBean中添加屬性absolutePath
        FileSystemResource file = new FileSystemResource(new File("C:\\Users\\華碩電腦\\Pictures\\nv1.jpg"));
        String fileName = "nv1.jpg";
        //添加附件,第一個參數表示添加到 Email 中附件的名稱，第二個參數是圖片資源
        mimeMessageHelper.addAttachment(fileName, file);
        //多個附件
        //mimeMessageHelper.addAttachment(fileName1, file1);

        mailSender.send(mimeMailMessage);
        return "發送成功";
    }

}
