【Spring Boot】邮件发送

1.导入Maven包

<!– 邮件发送 –>
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-mail</artifactId>
</dependency>

2.配置属性文件

application.properties

#这个配置可以为空，后面我们可以自定义从数据库
#或者从文件拿到对应的参数实现动态的配置邮件
#邮件发送配置
spring.mail.host=
spring.mail.username=
spring.mail.password=
spring.mail.port= 465
spring.mail.protocol=smtp
spring.mail.default-encoding=UTF-8
spring.mail.properties.smtp.auth=true
spring.mail.properties.smtp.starttls.enable=true
spring.mail.properties.smtp.starttls.required=true
spring.mail.properties.mail.smtp.ssl.enable=true

3.编写邮件代码

Email.java

package com.liuliu.com.service;

import com.liuliu.com.domain.Email;

public interface EmailService {
    public void emailText(Email email, String to, String subject, String text);
}

EmailServiceImpl.java

package com.liuliu.com.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.liuliu.com.domain.Email;
import com.liuliu.com.service.EmailService;

@Service("EmailServiceImpl")
public class EmailServiceImpl implements EmailService{
    @Autowired
    private JavaMailSenderImpl mailSender;

    public void emailText(Email email, String to, String subject, String text) {
// 发送邮件
//email发送属性的配置
//to收信人
//subject发送的标题
//text发送的内容
        SimpleMailMessage simpleMailMessage = new SimpleMailMessage();
        mailSender.setUsername(email.getEmailUsername());
        mailSender.setHost(email.getEmailHost());
        mailSender.setPassword(email.getEmailPassword());
        mailSender.setPort(email.getEmailPort());
        simpleMailMessage.setTo(to);
        simpleMailMessage.setFrom(email.getEmailCall());
        simpleMailMessage.setSubject(subject);
        simpleMailMessage.setText(text);
        mailSender.send(simpleMailMessage);
    }
}
