新建一个枚举Messages
package com.example.demo.email;
public enum Messages {
STOP(-1,"暂停服务","stop")
,SUCCESS(2000,"成功","success")
,SYSTEM_ERROR(9999,"系统错误","system error")
,AUTH_FAIL(4001,"无访问权限","no access")
,USERNAME_PASSWORD_FAIL(4002, "用户名或密码错误", "username or password error")

,PASSWORD_EMPTY(4004, "密码不能为空", "password is null")
,VERIFICATION_CODE_ERROR(4005,"验证码错误", "Verification code error")
,EMAIL_EMPTY(4006,"邮箱不能为空","Email is null")
,EMAIL_INVALID(4007,"邮箱不合法","email invalid")
,VERIFICATION_CODE_EMPTY(4008, "验证码不能为空", "verification code is null")
,USERNAME_EXISTS(4009, "用户名已存在", "username exists")
,EMAIL_EXISTS(4010,"邮箱已经存在", "email exists")
,EMAIL_NOT_EXISTS(4011,"邮箱不存在", "email not exists")
,INVITE_CODE_EXISTS(4012,"推荐码不存在", "invite code not exists")
,AVAILABLE_ASSETS_INSUFFICIENT(4013,"可用资产不足", "available assets insufficient")
,PROHIBIT_LOGIN(4014,"禁止登录", "prohibit login")
,CONCURRENT_EXECUTOR_ERROR(5000,"当前访问人数较多，请稍后再试","")

private int code;
private String de;
private String zh;
private String en;
Messages(int code, String zh, String en) {
this.de = zh;
this.code = code;
this.zh = zh;
this.en = en;
}
public enum Lang {
de,zh,en;
}
public int getCode() {
return code;
}
public String getDe() {
return de;
}
public String getZh() {
return zh;
}
public String getEn() {
return en;
}
}
新建一个MessageListener类
package com.example.demo.email;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.event.EventListener;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Component;
import javax.mail.internet.MimeMessage;
@Component
public class MessageListener {
@Autowired
private JavaMailSender mailSender;
@EventListener
@Async
public void simpleMailMessagEvent(SimpleMailMessagEvent event) throws Exception {
mailSender.send((SimpleMailMessage)event.getSource());
}
@EventListener
@Async
public void mimeMailMessagEvent(MimeMailMessagEvent event) throws Exception {
mailSender.send((MimeMessage)event.getSource());
}
}
新建MailMessageService类
package com.example.demo.email;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.ApplicationContext;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Service;
@Service
public class MailMessageService {
@Value("${spring.mail.username}")
private String username;
@Autowired
private ApplicationContext applicationContext;
/**
* 发送简单邮件
* @param subject 主题
* @param text 内容
* @param to 收件人
*/
public void sendSimple(String subject, String text, String... to){
SimpleMailMessage message = new SimpleMailMessage();
message.setFrom(username);
message.setTo(to);
message.setSubject(subject);
message.setText(text);
applicationContext.publishEvent(new SimpleMailMessagEvent(message));
}
}
新建一个接口Constants
package com.example.demo.email;
import java.math.BigDecimal;
public interface Constants {
String X_AUTH_TOKEN = "X-AUTH-TOKEN";
// token过期时间单位分钟
long TOKEN_EXPIRATION_TIMEOUT = 120L;
// 邮箱注册验证码前缀
String REGISTER_MAIL_CODE_PREFIX = "REGISTER_MAIL_CODE_";
// 邮箱登录验证码前缀
String LOGIN_MAIL_CODE_PREFIX = "LOGIN_MAIL_CODE_";
// 国际化参数
String LANGUAGE = "lang";
// token存储前缀
String TOKEN_PREFIX = "token_";
// 用户与token关系
String USER_TOKEN_PREFIX = "user_token_";
// 小于这个值则忽略不计算
BigDecimal IGNORE_EXEC = new BigDecimal(0.000001);
// redis和token关系
String LOGIN_TOKEN="LOGIN_TOKEN_";
// MD5和salt关系
String MD5_SALT="hehongqian";
}
新建一个MimeMailMessagEvent类
package com.example.demo.email;
import org.springframework.context.ApplicationEvent;
import org.springframework.mail.javamail.MimeMailMessage;
public class MimeMailMessagEvent extends ApplicationEvent {
private static final long serialVersionUID = -6424588529678254971L;
public MimeMailMessagEvent(MimeMailMessage message) {
super(message);
}
}
新建一个SimpleMailMessageEvent类
package com.example.demo.email;
import org.springframework.context.ApplicationEvent;
import org.springframework.mail.SimpleMailMessage;
public class SimpleMailMessagEvent extends ApplicationEvent {
private static final long serialVersionUID = -6424588529678254971L;
public SimpleMailMessagEvent(SimpleMailMessage message) {
super(message);
}
}
新建一个MailMessageController类
package com.example.demo.controller;
/*
* @Author: i_heh
* @CreateDate: 2019/7/1
* @CreateTime: 11:01
*/
import com.example.demo.email.MailMessageService;
import org.flowable.engine.ProcessEngine;
import org.flowable.engine.ProcessEngineConfiguration;
import org.flowable.engine.impl.cfg.StandaloneProcessEngineConfiguration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/mail")
public class MailMessageController {
@Autowired
private MailMessageService mailMessageService;
// 测试邮件
private static String topic = "测试邮件";
// 内容
private static String text = "今天天气真好！！！！！！！！！！！！！！！！！！";
// 收件人
private static String to = "i_hehongqian@sina.com";
// 发送文字邮件
@RequestMapping("/send")
public String sendMail(){
mailMessageService.sendSimple(topic,text,to);
return "发送成功";
}
// 发送带附件邮件
@RequestMapping("/sendFile")
public String sendFileMail(){
return null;
}
}
在properties文件加入
spring.mail.host=smtp.sina.com
spring.mail.username=i_hehongqian@sina.com
spring.mail.password=
spring.mail.port=465
spring.mail.default-encoding=UTF-8
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.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
spring.mail.password中的密码是需要登录到自己的邮箱，在设置-》账户里面开启POP3/SMTP服务，然后就会生成一个密码
