springboot整合mail实现邮箱的发送功能 springboot整合mail实现邮箱的发送

第一步添加mail的依赖

org.springframework.bootspring-boot-starter-mail

【springboot整合mail实现邮箱的发送功能】第二步编写邮箱的
yml配置文件

spring:#邮箱配置mail:host: smtp.qq.comusername: 2631245486@qq.com#QQ邮箱的授权码password: 授权码default-encoding: UTF-8properties:mail:smtp:auth: truestarttls:enable: truerequired: true

properties的配置文件

#qq邮箱配置# JavaMailSender 邮件发送的配置spring.mail.host=smtp.qq.comspring.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=truespring.mail.properties.mail.smtp.starttls.enable=truespring.mail.properties.mail.smtp.starttls.required=truespring.mail.default-encoding=UTF-8#163邮箱配置spring.mail.host=smtp.163.comspring.mail.username=用户163邮箱spring.mail.password=邮箱密码spring.mail.properties.mail.smtp.auth=truespring.mail.properties.mail.smtp.starttls.enable=truespring.mail.properties.mail.smtp.starttls.required=truespring.mail.default-encoding=UTF-8

编写两个发送邮件的接口

package www.it.com.server; import java.io.File; /*** @author wangjie:* @version 创建时间：2019年8月27日上午10:13:08* @Description 类描述:*/public interface MailServer { /*** @param sendUser 邮件接收人 * @param title 邮件的标题 * @param text邮件的内容*/ void sendMailServer(String sendUser,String title,String text); /*** 带有附件邮箱的发送* @param sendUser* @param title* @param text* @param file*/ void sendFileMail(String sendUser,String title,String text,File file); }

接口的实现

package www.it.com.server.impl; import java.io.File; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import org.apache.logging.log4j.message.SimpleMessage; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.core.io.FileSystemResource; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service; import www.it.com.server.MailServer; /*** @author wangjie:* @version 创建时间：2019年8月27日上午10:13:58* @Description 类描述:*/@Servicepublic class MailServerImpl implements MailServer { @Value("${spring.mail.username}") private String fromUser; @Autowiredprivate JavaMailSender javaMailSender; public String getFromUser() {return fromUser; } public void setFromUser(String fromUser) {this.fromUser = fromUser; } @Override public void sendMailServer(String sendUser, String title, String text) {//创建邮件的实体用于封装发送邮件需要的信息SimpleMailMessage simpleMailMessage=newSimpleMailMessage(); //邮件的发送人simpleMailMessage.setFrom(fromUser); //邮件接收人simpleMailMessage.setTo(sendUser); //邮件的标题simpleMailMessage.setSubject(title); //邮件的内容simpleMailMessage.setText(text); //发送邮件javaMailSender.send(simpleMailMessage); } @Override public void sendFileMail(String sendUser, String title, String text, File file) {MimeMessage mimeMessage = null; try {mimeMessage =javaMailSender.createMimeMessage(); //创建mimeMessageHelper对象用于处理带有附件的邮件信息MimeMessageHelper mimeMessageHelper=new MimeMessageHelper(mimeMessage,true); mimeMessageHelper.setFrom(fromUser); mimeMessageHelper.setTo(sendUser); mimeMessageHelper.setSubject(title); mimeMessageHelper.setText(text); FileSystemResource r = new FileSystemResource(file); //添加附件mimeMessageHelper.addAttachment("附件", r); javaMailSender.send(mimeMessage); } catch (MessagingException e) {// TODO Auto-generated catch blocke.printStackTrace(); } }}

controller编码

package www.it.com.controller; import java.io.File; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import www.it.com.server.MailServer; /** * @author wangjie: * @version 创建时间：2019年8月27日上午9:52:30 * @Description 类描述:邮件发送的controller */@RestController()@RequestMapping("/mail")public class MailController { @Autowired private MailServer mailServer; /*** 简单邮件的发送* @return*/ @RequestMapping("/send") public String sendMail() {//2694433816mailServer.sendMailServer("2631245486@qq.com", "你好", "明天去你家玩"); return "success"; } /*** 发送带有附件的邮件*/ @RequestMapping("/sendFile") public String sendFileMail() {File file=new File("C://Users//DELL//Desktop//学习资料.txt"); mailServer.sendFileMail("2631245486@qq.com", "你好dsf", "这是第二封带有附件的邮件", file); return "success"; }}
