新建EmailService.java

package com.github.ekko.springtools.service;import com.github.ekko.springtools.model.Weather;import java.util.List;public interface EmailService { boolean sendSimpleMessage(); List<Weather> getWeather();}

代码中的APPID
与APPSECRET
这里以腾讯邮箱为例子 ,先获取发送邮件的授权码
查询其邮箱的SMTP
地址 ,链接 ,可以看到
使用SSL的通用配置如下: 接收邮件服务器:pop.qq.com,使用SSL,端口号995 发送邮件服务器:smtp.qq.com,使用SSL,端口号465或587 账户名:您的QQ邮箱账户名(如果您是VIP帐号或Foxmail帐号,账户名需要填写完整的邮件地址) 密码:您的QQ邮箱密码 电子邮件地址:您的QQ邮箱的完整邮件地址
server.port=9090 server.servlet.context-path=/mail spring.mail.host=smtp.qq.com spring.mail.port=465 spring.mail.username=你的邮箱地址 spring.mail.password=刚刚获取的授权码 spring.mail.properties.mail.smtp.auth=true spring.mail.properties.mail.smtp.ssl.enable=true spring.mail.properties.mail.smtp.starttls.enable=true
声明 @EnableScheduling
定时任务
给指定方法设置时间表达式@Scheduled(cron = "0 0 8 * * ? ")
package com.github.ekko.springtools.controller;import com.github.ekko.springtools.model.Weather;import com.github.ekko.springtools.service.EmailService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.scheduling.annotation.EnableScheduling;import org.springframework.scheduling.annotation.Scheduled;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;import java.util.List;@RestController@EnableSchedulingpublic class MailController { private EmailService emailService; @Autowired public void setEmailService(EmailService emailService) { this.emailService = emailService; } @GetMapping("/send") @Scheduled(cron = "0 0 23 * * ? ") public boolean sendEmail() { return emailService.sendSimpleMessage(); } @GetMapping("get-weather") public List<Weather> getWeather() { return emailService.getWeather(); }}
直接启动SpringbootEmailApplication
package com.github.ekko.springtools;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class SpringbootEmailApplication { public static void main(String[] args) { SpringApplication.run(SpringbootEmailApplication.class, args); }}
