### SpringBoot邮件任务 ###

*  1、引入starter
 *  2、发送流程：
 *  3、配置application.properties
 *  4、测试简单邮件发送
 *  5、测试带附件的邮件发送

# 1、引入starter #

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

# 2、发送流程： #

# 3、配置application.properties #

如果用的是application.yml照着配就行，原理一样的

spring.mail.username=1144722582@qq.com
    spring.mail.password=*******
    spring.mail.host=smtp.qq.com

上面的第二个是授权码(我打码了)，你自己去qq邮箱上面开启相应服务即可

**最后生成授权码：**

# 4、测试简单邮件发送 #

package com.atguigu.springboot;
    
    import org.junit.jupiter.api.Test;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.mail.MailSender;
    import org.springframework.mail.SimpleMailMessage;
    import org.springframework.mail.javamail.JavaMailSenderImpl;
    import org.springframework.mail.javamail.MimeMessageHelper;
    
    import javax.mail.internet.MimeMessage;
    import java.io.File;
    
    @SpringBootTest
    class Springboot04TaskApplicationTests { 
        @Autowired
        JavaMailSenderImpl mailSender;
    
        @Test
        void contextLoads() { 
            SimpleMailMessage message = new SimpleMailMessage();
            //右键设置
            message.setSubject("通知-今晚开会");
            message.setText("今晚7:30开会");
    
            message.setTo("xiongtete0519@163.com");
            message.setFrom("1144722582@qq.com");
    
            mailSender.send(message);
        }
     
    }

运行之后去网易邮箱查看：

# 5、测试带附件的邮件发送 #

package com.atguigu.springboot;
    
    import org.junit.jupiter.api.Test;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.mail.MailSender;
    import org.springframework.mail.SimpleMailMessage;
    import org.springframework.mail.javamail.JavaMailSenderImpl;
    import org.springframework.mail.javamail.MimeMessageHelper;
    
    import javax.mail.internet.MimeMessage;
    import java.io.File;
    
    @SpringBootTest
    class Springboot04TaskApplicationTests { 
        @Autowired
        JavaMailSenderImpl mailSender;
    
        @Test
        public void test02() throws Exception{ 
            //1、创建一个复杂的消息邮件
            MimeMessage mimeMessage = mailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
            //右键设置
            helper.setSubject("通知-今晚开会");
            helper.setText("<b style='color:red'>今天7:30开会</b>",true);
    
            helper.setTo("xiongtete0519@163.com");
            helper.setFrom("1144722582@qq.com");
    
            //上传文件
            helper.addAttachment("03.jpg",new File("C:\\Users\\Peroy\\Pictures\\Saved Pictures\\03.jpg"));
            helper.addAttachment("preview.jpg",new File("C:\\Users\\Peroy\\Pictures\\Saved Pictures\\preview.jpg"));
    
            mailSender.send(mimeMessage);
        }
    
    }

最后的两个文件你用你自己电脑里面的就行，我是传了两张照片。
