springboot邮箱验证功能部署到服务器后报25 timeout的解决方式

可以写在application.yml中或者 写在配置类中, 如下; 原理就是更改端口,并且配置ssl的相关配置

package com.wfszmg.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.JavaMailSenderImpl;

import java.util.Properties;

/**

@Configuration
public class MailSenderConfiguration {

    @Autowired
    JavaMailSenderImpl sender;

    @Bean
    public JavaMailSenderImpl sender(){
        JavaMailSenderImpl sender = new JavaMailSenderImpl();
        sender.setHost("smtp.qq.com");
        sender.setUsername("qq@qq.com");
        sender.setPassword("zsazrzsaqnxwdjbc");
        sender.setDefaultEncoding("UTF-8");
        sender.setProtocol("smtp");
        sender.setPort(465);
        //配置properties
        Properties properties = new Properties();
        properties.setProperty("mail.smtp.auth", "true");
        properties.setProperty("mail.transport.protocol", "smtp");
        properties.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        properties.setProperty("mail.smtp.socketFactory.fallback", "false");

        sender.setJavaMailProperties(properties);
        return sender;
    }

}
