Java实现定时发送天气预报-创新互联
Spring Boot是由Pivotal团队提供的全新框架,其设计目的是用来简化新Spring应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置,从而使开发人员不再需要定义样板化的配置。

可以在Spring仓库中手动下载和安装。一种更为简便的方式是使用Groovy环境管理器(Groovy enVironment Manager,GVM),它会处理Boot版本的安装和管理。Boot及其CLI可以通过GVM的命令行gvm install springboot进行安装。在OS X上安装Boot可以使用Homebrew包管理器。为了完成安装,首先要使用brew tap pivotal/tap切换到Pivotal仓库中,然后执行brew install springboot命令。

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配置appliction.properties
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控制层
@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启动类getWeather() { return emailService.getWeather(); }}
SpringbootEmailApplication即可
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); }}效果
