利用开发者模式，实现qq邮箱推送(可利用定时器添加多个推送)
业务需求
1.要有一个关于超时推送的定时器,可随时关闭及维护
2.推送类型: 体检报告、资料审核、培训审核等等
3.推送的内容做成模板(创建一张表)要求可以维护而且模板可分为多个用户类型模板
4.推送可以维护提醒间隔时间(创建一张表)，例如：下次体检为2020-10-09，距离下次体检30天提醒一次，15天提醒一次
5.可以根据提醒间隔来设置是否生成工单
6.而且要有发送记录(创建一张表)
注意：可能写的不好，还望多指教，框架用的ssm，因为在自己开发中遇到的需求，做一下笔记，完整代码有点多，有很多实体类没有写，就是那些表的截图，大致实现方式就是这样的，也可以再添加其它的推送技术，如：短信、公众号，都可以，只要推送类继承Observer 观察者实现update方法即可
使用的工具类为hutool工具类连接:https://www.hutool.cn/
设计模式之观察者模式理论:https://blog.csdn.net/weixin_43861630/article/details/108978667
1.在resources文件下的config文件中新建mail.setting文件
hutool文档地址：https://www.hutool.cn/docs/#/extra/%E9%82%AE%E4%BB%B6%E5%B7%A5%E5%85%B7-MailUtil?id=%e5%8f%91%e9%80%81%e9%82%ae%e4%bb%b6
1）mail.setting
# 邮件服务器的SMTP地址，可选，默认为smtp.<发件人邮箱后缀>
host = smtp.qq.com
# 邮件服务器的SMTP端口，可选，默认25
port = 25
# 发件人（必须正确，否则发送失败）
from = 发件人邮箱 例如: 昵称<qq号@qq.com>
# 用户名，默认为发件人邮箱前缀
user = qq号
# 密码（注意，某些邮箱需要为SMTP服务单独设置密码---在这里是SMTP授权码）
pass = 授权码
2.pom
要引入第三方jar
cn.hutool
hutool-all
5.4.0
javax.mail
mail
1.4.7
3.实体类创建
1.）创建Observer 抽象观察者
package com.hx.slj.modules.zyb.ObserverModel;
/**
* @author qb
* @version 1.0
* @Description
* 抽象观察者
* @date 2020/8/24 13:51
*/
public interface Observer {
public void update(PushEntity pushEntity);
}
2.）创建Observerable抽象被观察者
package com.hx.slj.modules.zyb.ObserverModel;
/**
* @author qb
* @version 1.0
* @Description
* 抽象被观察者
* 声明添加、删除、通知观察者方法
* @date 2020/8/24 13:49
*/
public interface Observerable {
/**
* 添加
* @param o
*/
public void registerObserver(Observer o);
/**
* 删除
* @param o
*/
public void removeObserver(Observer o);
/**
* 通知观察者
*/
public void notifyObserver(PushEntity pushEntity);
}
3.)创建PushEntity 观察者通知参数
package com.hx.slj.modules.zyb.ObserverModel;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
/**
* @author qb
* @version 1.0
* @Description 观察者通知参数
* @date 2020/8/24 17:52
*/
@Data
@AllArgsConstructor
@NoArgsConstructor
public class PushEntity {
/**
* 企业id
*/
private String id;
/**
* 触发的提醒间隔id
*/
private String txjgId;
/**
* 各种报告id
*/
private String bgId;
/**
* 是否生成工单
*/
private String hasWo;
/**
* 推送类型
*/
private String pushType;
}
4.）创建OvertimePushServer 观察者主题
package com.hx.slj.modules.zyb.ObserverModelImpl;
import com.hx.slj.modules.zyb.ObserverModel.Observer;
import com.hx.slj.modules.zyb.ObserverModel.Observerable;
import com.hx.slj.modules.zyb.ObserverModel.PushEntity;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import java.util.ArrayList;
import java.util.List;
/**
* @author qb
* @version 1.0
* @Description 观察主题
* @date 2020/8/24 14:10
*/
@Data
@AllArgsConstructor
@NoArgsConstructor
public class OvertimePushServer implements Observerable {
private List<Observer> list = new ArrayList<>();
@Override
public void registerObserver(Observer o) {
System.err.println(o);
list.add(o);
}
@Override
public void removeObserver(Observer o) {
if(!list.isEmpty()){
list.remove(o);
}
}
@Override
public void notifyObserver(PushEntity pushEntity) {
for(int i=0;i<list.size();i++){
Observer observer = list.get(i);
observer.update(pushEntity);
}
}
}
5.)创建zybPushEntity 超时推送实体类
package com.hx.slj.modules.zyb.ObserverModel;
import com.hx.slj.modules.zyb.entity.ZybWoTxjg;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.NoArgsConstructor;
import java.util.Date;
/**
* @author qb
* @version 1.0
* @Description 超时推送公用实体
* @date 2020/9/1 10:28
*/
@Data
@AllArgsConstructor
@NoArgsConstructor
public class zybPushEntity {
private String id;
/**
* 企业id
*/
private String enterpriseid;
/**
* 下次时间
*/
private Date nextTime;
/**
* 实体类型
*/
private String entityType;
/**
* 提醒间隔 实体类
*/
private ZybWoTxjg zybWoTxjg;
}
6.)创建TemplateParsing 自定义模板解析类
package com.hx.slj.modules.zyb.TemplateParsing;
import java.util.Map;
import java.util.Set;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
/**
* @author qb
* @version 1.0
* @Description 模板解析 {
{name}} ==》 name(赋值后)
* @date 2020/8/24 15:51
*/
public class TemplateParsing {
/**
* 模板解析
* @param content
* @param map
* @return
*/
public static String renderString(String content, Map<String,String> map){
Set<Map.Entry<String,String>> sets = map.entrySet();
try{
for(Map.Entry<String,String> entry : sets){
//定义正则
String regex = "\\{\\{" + entry.getKey() + "\\}\\}";
//创建匹配模式
Pattern pattern = Pattern.compile(regex);
//将要匹配的内容加入进行匹配的
Matcher matcher = pattern.matcher(content);
//将匹配的结果替换为map的value值
content = matcher.replaceAll(entry.getValue() == null ? "null" : entry.getValue());
}
}catch (ClassCastException e){
new ClassCastException("格式错误，模板解析时map都应为string类型");
return "格式错误，模板解析时map中的value都应为string类型";
}
return content;
}
}
7.)创建推送工具类 只写了qq邮箱
package com.hx.slj.modules.zyb.utils;
import cn.hutool.extra.mail.MailUtil;
import java.io.File;
import java.util.ArrayList;
/**
* @author qb
* @version 1.0
* @Description 推送工具类
* @date 2020/8/19 15:24
*/
public class PushUtil {
/**
* 邮箱工具类，mail配置文件中，指定邮箱类型
* @param to 收件人
* @param subject 邮件主题
* @param content 邮寄内容(可以是文本，也可以是html)
* @param isHtml 是否是html
* @param files 附件
*/
public static void SendMail(String to, String subject, String content, Boolean isHtml, File... files){
if(files == null || files.length <=0){
MailUtil.send(to, subject, content, isHtml);
}else{
MailUtil.send(to, subject, content, isHtml,files);
}
}
}
4.创建qq推送类继承观察者
package com.hx.slj.modules.zyb.ObserverModelImpl;
import cn.hutool.core.date.DateUtil;
import cn.hutool.core.util.IdUtil;
import cn.hutool.core.util.StrUtil;

难点怎么确定30天和15天发没发送过
sql
在写sql时遇到的难点，以下下sql，可以将发送记录中存在的数据(15、30天等)去除，只取发送记录中不存在的数据
project_type='ZYB_QYTJXX’此条件为获取体检数据
<select id="selectOverTime" resultType="com.hx.slj.modules.zyb.ObserverModel.zybPushEntity">
select
a.id as "id",
a.enterpriseId as "enterpriseid",
a.nexttjTime as "nextTime",
b.id as "zybWoTxjg.id",
b.txts as "zybWoTxjg.txts",
b.has_wo as "zybWoTxjg.hasWo"
from zyb_qytjxx a cross join zyb_wo_txjg b where nexttjTime < date_add(SYSDATE(), INTERVAL b.txts day)
and not exists(select 1 from zyb_wo_fsjl c where c.txjg_id=b.id and c.project_id=a.id and project_type='ZYB_QYTJXX')
and a.nexttjTime > '2020-08-01'
select>
