大家好，本篇文章主要講的是Spring?Boot整合郵箱發(fā)送郵件實(shí)例，感興趣的同學(xué)趕快來(lái)看一看吧，對(duì)你有幫助的話記得收藏一下

1. 準(zhǔn)備工作

登錄進(jìn)自己的 qq 郵箱獲取授權(quán)碼

設(shè)置 – 賬戶(hù) – POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服務(wù)

點(diǎn)擊開(kāi)始獲取授權(quán)碼，將授權(quán)碼保存下來(lái)，下面代碼整合的時(shí)候需要使用

2. 代碼整合

創(chuàng)建一個(gè) Spring Boot 項(xiàng)目，引入以下依賴(lài)

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

配置文件

server:
  port: 8080
spring:
  # email 配置
  mail:
    # SMTP 服務(wù)器地址
    host: smtp.qq.com
    username: # 你的qq 郵箱地址
    password: # 授權(quán)碼，上面從 qq 郵箱官網(wǎng)得到的授權(quán)碼
    port: 587
    protocol: smtp
    default-encoding: UTF-8

創(chuàng)建一個(gè)郵件收件人信息的實(shí)體類(lèi)

/**
 * @author lishisen
 * @description 郵件收件人信息
 * @date 2022/1/9 9:37
 **/
@AllArgsConstructor
@NoArgsConstructor
@Data
public class EmailModel implements Serializable {

    // 收件人郵箱地址
    private String receiveEmailAddress;
    // 郵箱主題
    private String emailTheme;
    // 郵件內(nèi)容
    private String emailContent;

}

創(chuàng)建一個(gè)服務(wù)提供類(lèi)，SendEmailService.java

測(cè)試使用

    emailModel.setEmailContent("測(cè)試發(fā)送郵箱主體信息內(nèi)容");
    // 調(diào)用發(fā)送服務(wù)方法執(zhí)行發(fā)送任務(wù)
    sendEmailService.sendEmailAsText(emailModel);
