邮件的自动配置类为 org.springframework.boot.autoconfigure.mail.MailSenderAutoConfiguration
。
下面以 QQ 邮箱给 GMail 邮箱发送邮件为例。
1、使用 Maven 创建 SpringBoot 项目,引入 Web 场景启动器。
2、引入 Mail 场景启动器:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
3、获取 qq 邮箱授权码,登录进入 qq 邮箱,进入设置,选择账户,选择生成授权码:
4、邮箱相关配置:
# application.properties
spring.mail.username=632404164@qq.com
// 使用生成的授权码
spring.mail.password=nffutccjfabdbchc
spring.mail.host=smtp.qq.com
# qq 邮箱需要开启 ssl
spring.mail.properties.mail.smtp.sll.enable=true
5、测试:
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.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 MailApplicationTests {
@Autowired
JavaMailSender javaMailSender;
// 发送普通文本内容
@Test
public void test1() {
SimpleMailMessage mailMessage = new SimpleMailMessage();
// 设置邮件标题
mailMessage.setSubject("标题");
// 设置邮件内容
mailMessage.setText("hello");
mailMessage.setFrom("632404164@qq.com");
mailMessage.setTo("zhangzhongen326@gmail.com");
javaMailSender.send(mailMessage);
}
// 发送 html 内容带附件
@Test
public void test2() throws MessagingException {
MimeMessage mimeMessage = javaMailSender.createMimeMessage();
MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(mimeMessage, true);
// 设置标题
mimeMessageHelper.setSubject("标题");
// 设置内容
mimeMessageHelper.setText("<font color='red'>hello</font>",true);
// 设置附件,可设置多个
mimeMessageHelper.addAttachment("1.jpg", new File("C:\\Users\\Administrator\\Desktop\\1mail.png"));
mimeMessageHelper.setFrom("632404164@qq.com");
mimeMessageHelper.setTo("zhangzhongen326@gmail.com");
javaMailSender.send(mimeMessage);
}
}
