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。

创新互联建站专注于企业成都全网营销、网站重做改版、吉林网站定制设计、自适应品牌网站建设、H5建站、成都商城网站开发、集团公司官网建设、外贸营销网站建设、高端网站制作、响应式网页设计等建站业务，价格优惠性价比高，为吉林等各大城市提供网站开发制作服务。

Spring Boot

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。

设置发送账号信息

Java实现定时发送天气预报
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 getWeather() {
        return emailService.getWeather();
    }}

启动类

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);
	}}
