Springboot之整合mail
Springboot之整合mail
前言
Spring Email抽象的核心是MailSender接口，MailSender的实现能够将想要发送的邮件通过邮件服务器发送到用户邮箱，实现发送邮箱的功能。
发送邮件
MailSender接口
邮件服务器
用户邮箱
Spring 自带了一个 MailSender 的实现 JavaMailSenderImpl，它会使用 JavaMail API 来发送 Email。Spring 或 SpringBoot 应用在发送 Email 之前，我们必须要 JavaMailSenderImpl 装配为 Spring应用上下文的一个 bean。
配置
pom配置
org.springframework.boot
spring-boot-starter-mail
application.properties文件配置
- qq邮箱
# JavaMailSender 邮件发送的配置
spring.mail.host=smtp.qq.com
spring.mail.username=用户qq邮箱
#QQ邮箱的授权码
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
spring.mail.default-encoding=UTF-8
- 163邮箱
spring.mail.host=smtp.163.com
spring.mail.username=用户163邮箱
spring.mail.password=邮箱密码
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.default-encoding=UTF-8
host 属性默认是 JavaMail 会话的主机；port 端口默认监听标准的 SMTP 端口25；如果邮件服务器需要认证的，还需要设置 userrname 和 password。
通常username是邮箱号，password为邮箱的授权码。授权码可以登录邮箱获取。
设置->账户->POP3/SMTP服务:开启服务后会获得的授权码.
EmailConfig实体类
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
/**
* @Author youjp
* @Description //TODO
* @throw
**/
@Component
public class EmailConfig {
@Value("${spring.mail.username}")
private String emailForm;
public String getEmailForm() {
return emailForm;
}
public void setEmailForm(String emailForm) {
this.emailForm = emailForm;
}
}
EmailService
package com.example.email.com.example.email.demo;
/**
* @Param
* @return
* @Author youjp
* @Description //TODO
* @throw
**/
public interface EmailService {
//发送简单的邮件
void sendMailSimpleMail(String sendTo,String title,String content);
//发送html的邮件
void sendHtmlMail(String sendTo,String title,String content);
//发送带附件的邮件
void sendAttachmentMail(String sendTo, String title, String content);
}
EmailService实现类
package com.example.email.com.example.email.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;

import org.springframework.stereotype.Service;
import javax.mail.internet.MimeMessage;
import java.io.File;
/**

* @return
* @Author youjp
* @Description //TODO
* @throw
**/
@Service
public class EmailServiceImpl implements EmailService{
@Autowired
private EmailConfig emailConfig;
@Autowired
private JavaMailSender mailSender;
/**
* @Param [sendTo, title, content]
* @return void

EmailController 控制层
package com.example.email.com.example.email.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class EmailController {
@Autowired
private EmailService emailService;
@RequestMapping("/simple")
@ResponseBody
public String sendSimpleEmail(String sendTo) {
emailService.sendMailSimpleMail(sendTo, "发送简单邮件", "你好");
return "success";
}
@RequestMapping("/sendHtmlMail")
@ResponseBody
public String sendHtmlMail(String sendTo) {
emailService.sendHtmlMail(sendTo,"发送一个带html格式的邮件", "这是一封带html格式的邮件");
return "success";
}
@RequestMapping("/sendAttachMail")
@ResponseBody
public String sendAttachMail(String sendTo) {
emailService.sendAttachmentMail(sendTo,"发送带附件格式的邮件", "这是一封发送带附件格式的邮件");
return "success";
}
}
请求接口：
请求发送带附件格式的邮件
其他请求方式一样。
