springboot任务之邮件任务

Posted 2021-03-10 西西嘛呦

 

以QQ邮箱为例，我们先要在邮箱中设置--账户下找到以下向并开启：

 

1、首先是引入starter

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

2、在application.properties中进行配置

 

3、进行测试发送一份简单的邮件

package com.gong.spingbootes;

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.JavaMailSenderImpl;
import org.springframework.test.context.junit4.SpringRunner;


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

    @Autowired
    JavaMailSenderImpl mailSender;

    @Test
    public void contextLoads() {
        SimpleMailMessage message = new SimpleMailMessage();
        //邮件设置
        message.setSubject("通知今晚开会");
        message.setText("今晚七点三十开会");
        message.setTo("[e-mail]");
        message.setFrom("[e-mail]");
        mailSender.send(message);
    }
}

运行contextLoads方法，此时去到自己的[e-mail]上看一看：

 

好神奇。

下面再测试一个更加复杂的邮件，使用html以及带上附件。

package com.gong.spingbootes;

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.JavaMailSenderImpl;
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 SpingbootEsApplicationTests {

    @Autowired
    JavaMailSenderImpl mailSender;

    @Test
    public void contextLoads() {
        SimpleMailMessage message = new SimpleMailMessage();
        //邮件设置
        message.setSubject("通知今晚开会");
        message.setText("今晚七点三十开会");
        message.setTo("[e-mail]");
        message.setFrom("[e-mail]");
        mailSender.send(message);
    }

    @Test
    public void testSend() throws MessagingException {
        //创建复杂邮件
        MimeMessage message = mailSender.createMimeMessage();
        //邮件设置
        MimeMessageHelper messageHelper = new MimeMessageHelper(message,true);
        messageHelper.setSubject("通知今晚开会");
        messageHelper.setText("<b style=\'color:red\'>今晚七点三十开会</b>",true);
        messageHelper.setTo("[e-mail]");
        messageHelper.setFrom("[e-mail]");
        messageHelper.addAttachment("1.jpg",new File("I:\\\\amly.jpg"));
        mailSender.send(message);
    }
}
