springboot实现发送简单邮件

springboot实现发送简单邮件

1.新建一个springboot工程
2.导入发送邮件的依赖

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

3.在application.properties中添加邮箱配置

spring.mail.host=smtp.qq.com
[email protected]
spring.mail.password=授权码
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true

4.编写mailService,这里只提出实现类。

package com.tuanzi.Service;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Component;

@Component
public class MailServiceImpl implements MailService {

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Autowired
    private JavaMailSender mailSender;

    @Value("${spring.mail.username}")
    private String from;

    public void sendSimpleMail(String to, String subject, String content) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(content);

        try {
            mailSender.send(message);
            logger.info("简单邮件已经发送。");
        } catch (Exception e) {
            logger.error("发送简单邮件时发生异常！", e);
        }

    }
}

5.编写test类进行测试

package com.tuanzi;

import com.tuanzi.Service.MailService;
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.test.context.junit4.SpringRunner;

@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringbootMailApplicationTests {
    @Autowired
    private MailService mailService;
    @Test
    public void contextLoads() throws Exception{
         mailService.sendSimpleMail("[email protected]","测试邮件","这是一个测试邮件!");
    }

}

至此一个简单的文本发送就完成了。
赶快试一下吧！
