springboot整合java mail

1.准备工作

登录进qq邮箱，进入设置

接下来打开

打开设置：

记录下授权码，有用的

2.进行开发

2.1环境搭建

pom.xml

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

test—>用于单元测试

springbootmailstater—>用于邮件发送服务

applicaiton.properties

server.port=8080

#mail
spring.mail.host=smtp.qq.com
spring.mail.port=465
spring.mail.username=859240195@qq.com
spring.mail.protocol=smtp
spring.mail.password=你的授权码
spring.mail.default-encoding=utf-8
spring.mail.properties.mail.debug=true
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

mail的基本配置，没什么好说的，把授权码放在password那里，就可以了

在这里port可以设置为465或者587，都可以

2.2 发送简单邮件

package top.juntech.springbootmail.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.stereotype.Service;

/**
 * @author juntech
 * @version ${version}
 * @date 2019/12/13 13:40
 * @ClassName 类名
 * @Descripe 发送简单邮件
 */
@Service
public class MailService {
    @Autowired
    JavaMailSender javaMailSender;

    public void sendSimpleMail(String from,String to,String cc,String subject,String content){
        /*
        * 邮件信息
        * */
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        simpleMailMessage.setFrom(from);
        simpleMailMessage.setTo(to);
        simpleMailMessage.setCc(cc);
        simpleMailMessage.setSubject(subject);
        simpleMailMessage.setText(content);
        /*
        * 发送邮件
        * */
        javaMailSender.send(simpleMailMessage);
    }
}

代码解释：

​ javamailsender是springboot在mailsenderpropertiesConfiguration类中配置好的

​ sendSimplemail的5个参数分别是：发送者，接收者，抄送这，邮件主题，邮件内容

​ 简单邮件可以直接构建一个simplemailmessage对象进行配置，配置完成后通过javamailsender发送出去

2.3单元测试

package top.juntech.springbootmail;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import top.juntech.springbootmail.service.MailService;

@SpringBootTest
class SpringbootMailApplicationTests {
    @Autowired
    private MailService mailService;

    @Test
    void contextLoads() {
        mailService.sendSimpleMail(
                "859240195@qq.com",
                "zhoujay1997@gmail.com",
                "859240195@qq.com",
                "测试邮件主题",
                "测试邮件内容"
        );
    }

}

在查看邮箱：

2.4发送带附件的邮件

    /*
    * 发送带附件的邮件
    * */
    public void sendAttacheFileMail(String from, String to, String cc, String subject, String content, File file){
        try{
            MimeMessage mimeMessage = javaMailSender.createMimeMessage();
            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper();
            mimeMessageHelper.setFrom(from);
            mimeMessageHelper.setTo(to);
            mimeMessageHelper.setText(content);
            mimeMessageHelper.setCc(cc);
            mimeMessageHelper.setSubject(subject);
            mimeMessageHelper.addAttachment(file.getName(),file);
            javaMailSender.send(mimeMessage);
        }catch (Exception e){
            e.printStackTrace();
        }
    }
