Gmail 两步验证+应用专用密码登录

本文主要是介绍Gmail 两步验证+应用专用密码登录，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、为什么做这个？

如果需要使用Gmail作为应用程序的邮件发送者，必须进行相关配置，否则不能直接使用

2、怎么做？

2.1、登录谷歌账号：https://myaccount.google.com/u/6/signinoptions/two-step-verification/enroll-welcome?gar=1

2.2、应用专用密码设置入口：https://myaccount.google.com/u/6/apppasswords?gar=1

3、java 应用中如何使用Gmail可以参考如下：

4、如何支持多个发送邮箱配置

4.1、定义一个配置类

import cn.hutool.core.text.CharSequenceUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.javamail.JavaMailSenderImpl;import java.util.Properties;/*** @author : qinjinyuan* @desc : TODO  请填写你的功能描述* @date : 2024/06/03 13:36*/
@Configuration
public class EmailSenderConfig {@Value("${gmail.host}")private String gmailHost;@Value("${gmail.port}")private Integer gmailPort;@Value("${gmail.username}")private String gmailUsername;@Value("${gmail.password}")private String gmailPassword;@Value("${gmail.protocol}")private String gmailProtocol;@Autowiredprivate EmailNormalConfig emailNormalConfig;@Bean("gmailSender")public JavaMailSenderImpl gmailSender() {JavaMailSenderImpl mailSender = new JavaMailSenderImpl();mailSender.setHost(gmailHost);mailSender.setPort(gmailPort);mailSender.setUsername(gmailUsername);mailSender.setPassword(gmailPassword);mailSender.setProtocol(gmailProtocol);Properties properties = new Properties();properties.put("mail.smtp.auth", "true");properties.put("mail.smtp.starttls.enable", "true");mailSender.setJavaMailProperties(properties);return mailSender;}@Bean("otherSender")public JavaMailSenderImpl otherSender() {JavaMailSenderImpl mailSender = new JavaMailSenderImpl();mailSender.setHost(emailNormalConfig.getHost());mailSender.setPort(emailNormalConfig.getPort());mailSender.setUsername(emailNormalConfig.getUsername());mailSender.setPassword(emailNormalConfig.getPassword());if (CharSequenceUtil.isNotBlank(emailNormalConfig.getProtocol())) {mailSender.setProtocol(emailNormalConfig.getProtocol());}return mailSender;}

4.2、定义原生配置 EmailNormalConfig

import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.context.annotation.Configuration;/*** @author : qinjinyuan* @date : 2023/10/31 16:51*/
@Configuration
@RefreshScope
@ConfigurationProperties(prefix = "spring.mail")
@Getter
@Setter
public class EmailNormalConfig {private String host;private Integer port;private String username;private String password;private String from;private String protocol;
}

4.3、如何用，也可以自己写策略模式进行实现

import org.springframework.mail.javamail.JavaMailSender;@Resource(name = "otherSender")private JavaMailSender mailSender;或者@Resource(name = "gmailSender")
private JavaMailSender mailSender;
