Spring Boot任务管理之邮件任务

发送纯文本邮件

一、在pom.xml中添加邮件服务的依赖启动器

 

 

       <!--邮件服务依赖启动器-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-mail</artifactId>
        </dependency>

二、在全局配置文件中添加邮件服务配置

 

获取授权码操作步骤： https://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256

三、定制邮件发送任务

 

 

复制代码
package com.uos.email.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.stereotype.Service;

@Service
public class SendEmailService {
    @Autowired
    private JavaMailSenderImpl mailSender;
    @Value("${spring.mail.username}")
    private String from;
    public void sendSimpleEmail(String to, String subject, String text) {
        SimpleMailMessage message = new SimpleMailMessage();
        message.setFrom(from);
        message.setTo(to);
        message.setSubject(subject);
        message.setText(text);
        try {
            mailSender.send(message);
            System.out.println("纯文本邮件发送成功");
        } catch (MailException e) {
            System.out.println("纯文本邮件发送失败 " + e.getMessage());
            e.printStackTrace();
        }
    }
}
复制代码

四、测试类

 

五、运行结果

一、在SendEmailService中添加

 

 

复制代码
public void sendComplexEmail(String to, String subject, String text, String filePath, String rscId,
                                 String rscPath) {
        MimeMessage message = mailSender.createMimeMessage();
        try {
            MimeMessageHelper helper = new MimeMessageHelper(message, true);
            helper.setFrom(from);
            helper.setTo(to);
            helper.setSubject(subject);
            helper.setText(text, true);
            FileSystemResource res = new FileSystemResource(new File(rscPath));
            helper.addInline(rscId, res);
            FileSystemResource file = new FileSystemResource(new File(filePath));
            String fileName = filePath.substring(filePath.lastIndexOf(File.separator));
            helper.addAttachment(fileName, file);
            mailSender.send(message);
            System.out.println("复杂邮件发送成功");
        } catch (MessagingException e) {
            System.out.println("复杂邮件发送失败 " + e.getMessage());
            e.printStackTrace();
        }
    }
复制代码

二、在测试类中添加
