package com.demo;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMailMessage;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.test.context.junit4.SpringRunner;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import java.io.File;

@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {

    @Autowired
    private JavaMailSender mailSender;

    @Test
    public void contextLoads() {

        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom("514730393@qq.com");
        message.setTo("zdwbmw@163.com");
        message.setSubject("主题：简单邮件");
        message.setText("哈哈哈哈哈哈哈哈啊哈哈");

        mailSender.send(message);
    }

            @Test
            public  void  test02() throws MessagingException {
                //创建一个复杂的消息邮件  带附件
                MimeMessage mimeMessage =mailSender.createMimeMessage();
                MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);


                helper.setSubject("通知今晚开会");
                helper.setText("<b style='color:red'>hello world!</b>",true);

                helper.setFrom("514730393@qq.com");
                helper.setTo("zdwbmw@163.com");

                helper.addAttachment("新福音战士",new File("C:\\Users\\polo\\Desktop\\新福音战士 (1).png"));

                mailSender.send(mimeMessage);
