SpringBoot整合JavaMail邮件的两种方式
作者：陌殇殇
这篇文章主要介绍了SpringBoot整合JavaMail邮件的两种方式,本文通过实例代码给大家介绍的非常详细,感兴趣的朋友跟随小编一起看看吧
JavaMail邮件发送
1.方式一：SpringBoot整合JavaMailSender
1.yml配置提取
application:
mail:
smtp:
#服务器主机名
host: smtp.qq.com
#服务器端口
port: 465
#你的邮箱地址
username: 5XXXxxxx1@qq.com
#你的授权码
password: xxxxx
#编码格式
defaultEncoding: utf-8
#是否进行用户名密码校验
auth: true
#设置超时时间
timeout: 20000
#是否启用ssl
ssl-enabled: true/**
* 邮件配置
* @author li
*/
@Data
@ConfigurationProperties(prefix = "application.mail.smtp")
public class MailOptionProperties {
/**
* 服务器主机名
*/
private String host;
/**
* 服务器发送端口
*/
private String port;
/**
* 邮箱地址
*/
private String username;
/**
* 授权码
*/
private String password;
/**
* 编码格式
*/
private String defaultEncoding;
/**
* 是否进行用户名密码校验
*/
private String auth;
/**
* 设置超时时间
*/
private String timeout;
/**
* ssl启用
*/
private boolean sslEnabled;
}2.config配置
/**

* @author li
*/
@Configuration
@EnableConfigurationProperties({MailOptionProperties.class})
public class JavaMailConfig {
@Autowired
private MailOptionProperties mailOptionProperties;
@Bean
public JavaMailSender javaMailSender() throws GeneralSecurityException {

javaMailSender.setHost(mailOptionProperties.getHost());
javaMailSender.setUsername(mailOptionProperties.getUsername());
javaMailSender.setDefaultEncoding(mailOptionProperties.getDefaultEncoding());
javaMailSender.setPassword(mailOptionProperties.getPassword());
Properties properties = new Properties();
//开启认证
properties.setProperty("mail.smtp.auth", mailOptionProperties.getAuth());
//设置链接超时
properties.setProperty("mail.smtp.timeout", mailOptionProperties.getTimeout());
//启用调试
properties.setProperty("mail.debug", "true");
//设置端口
properties.setProperty("mail.smtp.port", mailOptionProperties.getPort());
//是否启用ssl
if(mailOptionProperties.getSslEnabled()){
//设置ssl端口
properties.setProperty("mail.smtp.socketFactory.port", mailOptionProperties.getPort());
properties.setProperty("mail.smtp.socketFactory.fallback", "false");
properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
//设置ssl加密
MailSSLSocketFactory sf = new MailSSLSocketFactory();
sf.setTrustAllHosts(true);
properties.put("mail.smtp.ssl.enable", mailOptionProperties.getSslEnabled());

}
javaMailSender.setJavaMailProperties(properties);
return javaMailSender;
}
}3.工具类
