【愚人节专场】Java实现定时发送小情话

首先，感谢大佬的帮助~附上大佬的博客以示尊敬https://blog.csdn.net/qq_38591577/article/details/128164308?spm=1001.2014.3001.5502

功能实现：

在名为愚人节，实为告白/情人节的日子里，怎么样才能引起TA的关注呢？不妨试着定时发送（土味）小情话来增进感情呢~

我的老婆们收到之后都开心的表示，不要捣鼓这些无聊的东西，不如抓紧去赚钱。

这是来自老婆的反馈：

咳咳，虽然被针对了，但是女人说不要那就是要(/▽＼)

框架设计：

2.1 创建springboot项目

此处注意尽量不要使用springboot3.0.0，我这里用的是2.7.10。

2.2 pom依赖

<!-- hutool 依赖-->
    <dependency>
        <groupId>cn.hutool</groupId>
        <artifactId>hutool-all</artifactId>
        <version>4.3.2</version>
    </dependency>
<!-- 邮件 依赖 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
        <version>2.4.3</version>
    </dependency>

2.3 application.yml (配置文件)

spring:
  mail:
    host: smtp.qq.com                  #邮箱发送服务器
    username: 181*******@qq.com       #邮箱地址
    password: abdsjszkazkjsad       #获取邮箱第三方使用秘钥
    protocol: smtp
    properties.mail.smtp.port: 25       #端口
    default-encoding: utf-8
she:
  mail: 114*******@qq.com
  mail2: 184*******@qq.com
  mail3: 182*******@qq.com

2.4 DemoApplication启动类

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

2.5 SendMailService.java （接口）

package com.example.demo.service.impl;

import org.springframework.stereotype.Service;
@Service
public interface SendMailService {
    void sendMessage(String sub, String message);

    String getLovePrattle();

    String getWeather();

}

2.6 SendMail.java (接口实现类)

package com.example.demo.service.impl;
import cn.hutool.http.HttpUtil;
import cn.hutool.json.JSONObject;
import cn.hutool.json.JSONUtil;
import com.sun.xml.internal.messaging.saaj.packaging.mime.MessagingException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;
import javax.mail.internet.MimeMessage;
import java.util.ArrayList;


@Component
public class SendMail implements SendMailService{
    @Resource
    private JavaMailSender mailSender;

    @Value("${spring.mail.username}")
    private String from;

    @Value("${she.mail}")
    private String[] sheMail;
    @Value("${she.mail2}")
    private String[] sheMail2;
    @Value("${she.mail3}")
    private String[] sheMail3;


    public void sendMessage(String subject,String message) {
        ArrayList<String[]> objects = new ArrayList<>();
        objects.add(sheMail);
        objects.add(sheMail2);
        objects.add(sheMail3);

        for (String[] object : objects) {
        try {
            MimeMessage mimeMessage = mailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(mimeMessage);
            helper.setFrom(from);       //发送方邮件名
            helper.setTo(object);         //接收方邮件地址
            helper.setSubject(subject);     //邮件标题
            helper.setText(message,true);   //邮件内容，是否为html格式
            mailSender.send(helper.getMimeMessage());
        } catch (javax.mail.MessagingException e) {
            e.printStackTrace();
        }}
    }
    @Override
    public String getLovePrattle() {
        String result1= HttpUtil.get("https://api.lovelive.tools/api/SweetNothings");
        System.out.println(result1);
        return result1;
    }

    //  实时天气
    @Override
    public String getWeather() {
        StringBuffer sb = new StringBuffer();
        String s = HttpUtil.get("https://devapi.qweather.com/v7/weather/now?location=101190113&key=f5fe849feaf24a60b54e6d6cb7062a8e");
        JSONObject jsonObject = JSONUtil.parseObj(s);
        System.out.println("时间为："+jsonObject.get("updateTime"));
        sb.append("<p>时间为："+jsonObject.get("updateTime")+"<br>\n");
        System.out.println("详细天气请查看"+jsonObject.get("fxLink"));
        sb.append("详细天气请查看"+jsonObject.get("fxLink")+"<br>\n");
        Object now = jsonObject.get("now");
        JSONObject nowJson = JSONUtil.parseObj(now);
        System.out.println("当前温度为"+nowJson.get("temp")+"℃");
        sb.append("当前温度为"+nowJson.get("temp")+"℃"+"<br>\n");
        System.out.println("天气状况为"+nowJson.get("text"));
        sb.append("天气状况为"+nowJson.get("text")+"<br>\n");
        System.out.println("风力等级"+nowJson.get("windScale")+"级");
        sb.append("风力等级"+nowJson.get("windScale")+"级"+"<br>\n");
        System.out.println("能见度"+nowJson.get("vis")+"公里");
        sb.append("能见度"+nowJson.get("vis")+"公里</p >");
        String weater = sb.toString();
        return weater;
    }

}

2.7 SchedueTask.java (定时任务配置类)

package com.example.demo.config;

import com.example.demo.service.impl.SendMail;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.Async;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;

import javax.annotation.Resource;

@Configuration      //主要用于标记配置类，兼备Component的效果。
@EnableScheduling   // 开启定时任务
public class ScheduleTask {
    @Resource
    SendMail sendMail;

    @Async
    @Scheduled(cron = "0 */1 * * * ?")//每分钟发一次（这里是用的是cron表达式，可以上网查阅）
    public void send(){
//        土味情话
        String one = sendMail.getLovePrattle();
//        String weather = sendMail.getWeather();

        sendMail.sendMessage("小点心",one);


    }
}
