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
三、定制邮件发送任务
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();
}
}
}
四、测试类
五、运行结果
发送带附件和图片的邮件
一、在SendEmailService中添加
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();
}
}
二、在测试类中添加
三、测试结果
发送模板邮件
一、在pom.xml中添加Thymeleaf模板引擎依赖启动器
二、定制模板邮件
