不知不觉,又到了雨季,你对象是不是经常忘记带伞呢,这个时候写一个自动定时发送邮件的程序,提醒她带伞,会不会对你崇拜有加呢,当然,如果你对象是一位攻城狮,当我没讲~

技术栈

Spring Boot 2.3.1

Jdk 1.8

Maven

快速创建实例

前往 https://start.spring.io/ 如下所示初始化项目点击GENERATE生产一个zip解压导入idea即可

新建接收天气api的实体

Weather.java

package com.github.ekko.springtools.model;import lombok.Data;import lombok.NoArgsConstructor;import java.util.List;@Data@NoArgsConstructorpublic class Weather {    private String day;    private String date;    private String week;    //天气情况    private String wea;    private String weaImg;    private String air;    private String humidity;    // 空气质量 优    private String airLevel;    // 空气质量描述:空气很好,可以外出活动,呼吸新鲜空气,拥抱大自然    private String airTips;    private String tem1;    private String tem2;    private String tem;    private List<Whours> hours;}

Whours.java

package com.github.ekko.springtools.model;import lombok.Data;import lombok.NoArgsConstructor;@Data@NoArgsConstructorpublic class Whours {    // 14日20时    private String day;    //中雨    private String wea;    //28℃ 实时温度    private String tem;    //无持续风向    private String win;    // 风速 3-4级    private String winSpeed;}

天气接口

用的是https://www.tianqiapi.com/index也没给我推广费,也作为我白嫖它这么久的回报吧天气接口

封装的天气api简单演示

在这里插入图片描述

获取天气api与发送邮件的逻辑

新建EmailService.java接口

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();}

实现EmailService接口

package com.github.ekko.springtools.service.impl;import cn.hutool.http.HttpRequest;import cn.hutool.http.HttpUtil;import com.alibaba.fastjson.JSON;import com.github.ekko.springtools.model.Weather;import com.github.ekko.springtools.service.EmailService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.mail.javamail.JavaMailSender;import org.springframework.mail.javamail.MimeMessageHelper;import org.springframework.stereotype.Service;import javax.mail.internet.MimeMessage;import java.util.ArrayList;import java.util.List;import java.util.Optional;@Servicepublic class EmailServiceImpl implements EmailService {    private final static String FROM_MAIL = "你的发送邮箱,和配置文件中相同";    private final static String TO_MAIL = "接收人邮箱";    private final static String APPID = "你申请的天气api的appid,自行替换";    private final static String APPSECRET = "你申请的天气api的APPSECRET,自行替换";    public JavaMailSender emailSender;    @Autowired    public void setEmailSender(JavaMailSender emailSender) {        this.emailSender = emailSender;    }    @Override    public boolean sendSimpleMessage() {        try {            MimeMessage message = emailSender.createMimeMessage();            MimeMessageHelper mimeMessageHelper = new MimeMessageHelper(message, true);            mimeMessageHelper.setTo(TO_MAIL);            mimeMessageHelper.setFrom(FROM_MAIL);            mimeMessageHelper.setSubject("今日份天气到了~~");            mimeMessageHelper.setText(buildHtml(getWeather().get(0)), true);            emailSender.send(message);        } catch (Exception e) {            e.printStackTrace();            return false;        }        return true;    }    public List<Weather> getWeather() {        HttpRequest httpRequest = HttpUtil.createGet("https://www.tianqiapi.com/api?version=v1&" + "appid=" + APPID + "&appsecret=" + APPSECRET + "&cityid=101020100");        String res = httpRequest.execute().body();        Object data = JSON.parseObject(res).get("data");        return JSON.parseArray(JSON.toJSONString(data), Weather.class);    }    private String buildHtml(Weather weather) {        StringBuffer html = new StringBuffer("");        html.append("<!DOCTYPE html>\n" +                "<html>\n" +                "<head>\n" +                "<meta charset=\"utf-8\">\n" +                "<title>文档标题</title>\n" +                "</head><body>");        if (weather.getWea().contains("雨")) {            html.append("<h1>今日有雨,狗子请带伞!</h1>");        }        html.append("<hr/><h3>今日天气如下</h3><table><tr><th>时间</th><th>天气</th><th>温度</th></tr>");        Optional.ofNullable(weather.getHours())                .orElse(new ArrayList<>())                .forEach(whours -> {                    html.append("<tr><td>")                            .append(whours.getDay())                            .append("</td><td>")                            .append(whours.getWea())                            .append("</td><td>")                            .append(whours.getTem())                            .append("</td></tr>");                });        html.append("</table></body>" +                "</html>");        return html.toString();    }}

代码中的APPIDAPPSECRET代码中的APPID与APPSECRET

设置发送账号信息

这里以腾讯邮箱为例子 ,先获取发送邮件的授权码获取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

配置appliction.properties

server.port=9090server.servlet.context-path=/mailspring.mail.host=smtp.qq.comspring.mail.port=465spring.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=truespring.mail.properties.mail.smtp.ssl.enable=truespring.mail.properties.mail.smtp.starttls.enable=true

控制层

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();    }}

启动类

直接启动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

有点丑,将就用,自行美化有点丑,将就用,自行美化
