#### 1. Announcement 模型类
java package com.example.oamodule.model;
import javax.persistence.Entity; import javax.persistence.Id; import java.time.LocalDateTime;
Entity public class Announcement { Id private String id; private String type; // TEXT, IMAGE, VIDEO private String content; private LocalDateTime publishTime; private LocalDateTime expiryTime; public Announcement() {} public Announcement(String id, String type, String content, LocalDateTime publishTime, LocalDateTime expiryTime) { this.id id; this.type type; this.content content; this.publishTime publishTime; this.expiryTime expiryTime; } // Getters and Setters public String getId() { return id; } public void setId(String id) { this.id id; } public String getType() { return type; } public void setType(String type) { this.type type; } public String getContent() { return content; } public void setContent(String content) { this.content content; } public LocalDateTime getPublishTime() { return publishTime; } public void setPublishTime(LocalDateTime publishTime) { this.publishTime publishTime; } public LocalDateTime getExpiryTime() { return expiryTime; } public void setExpiryTime(LocalDateTime expiryTime) { this.expiryTime expiryTime; } public boolean isExpired() { return LocalDateTime.now().isAfter(expiryTime); } }
#### 2. AnnouncementRepository 接口
java package com.example.oamodule.repository;
import com.example.oamodule.model.Announcement; import org.springframework.data.jpa.repository.JpaRepository; import org.springframework.stereotype.Repository;
import java.time.LocalDateTime; import java.util.List;
Repository public interface AnnouncementRepository extends JpaRepositoryAnnouncement, String { ListAnnouncement findByExpiryTimeAfter(LocalDateTime now); }
#### 3. AnnouncementService 服务类
java package com.example.oamodule.service;
import com.example.oamodule.model.Announcement; import com.example.oamodule.repository.AnnouncementRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service;
import java.time.LocalDateTime; import java.util.List;
Service public class AnnouncementService { Autowired private AnnouncementRepository announcementRepository; public void createAnnouncement(String id, String type, String content, LocalDateTime publishTime, LocalDateTime expiryTime) { Announcement announcement new Announcement(id, type, content, publishTime, expiryTime); announcementRepository.save(announcement); System.out.println(Announcement created: announcement.getId()); } public ListAnnouncement getAllAnnouncements() { return announcementRepository.findAll(); } public ListAnnouncement getActiveAnnouncements() { return announcementRepository.findByExpiryTimeAfter(LocalDateTime.now()); } public void removeExpiredAnnouncements() { ListAnnouncement announcements announcementRepository.findAll(); for (Announcement announcement : announcements) { if (announcement.isExpired()) { announcementRepository.delete(announcement); } } } }
#### 4. NotificationService 服务类
java package com.example.oamodule.service;
import com.example.oamodule.model.Announcement; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.stereotype.Service;
import java.util.List;
Service public class NotificationService { Autowired private JavaMailSender mailSender; public void sendNotifications(ListAnnouncement announcements) { for (Announcement announcement : announcements) { // 模拟推送到电子邮件 SimpleMailMessage message new SimpleMailMessage(); message.setTo(employeeexample.com); message.setSubject(New Announcement: announcement.getType()); message.setText(announcement.getContent()); mailSender.send(message); System.out.println(Sent notification for announcement: announcement.getId()); } } }
#### 5. AnnouncementController 控制器类
java package com.example.oamodule.controller;
import com.example.oamodule.model.Announcement; import com.example.oamodule.service.AnnouncementService; import com.example.oamodule.service.NotificationService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.*;
import java.time.LocalDateTime; import java.util.List;
RestController RequestMapping(/announcements) public class AnnouncementController { Autowired private AnnouncementService announcementService; Autowired private NotificationService notificationService; PostMapping public void createAnnouncement(RequestBody Announcement announcement) { announcementService.createAnnouncement(announcement.getId(), announcement.getType(), announcement.getContent(), announcement.getPublishTime(), announcement.getExpiryTime()); notificationService.sendNotifications(List.of(announcement)); } GetMapping public ListAnnouncement getAllAnnouncements() { return announcementService.getAllAnnouncements(); } GetMapping(/active) public ListAnnouncement getActiveAnnouncements() { return announcementService.getActiveAnnouncements(); } DeleteMapping(/expired) public void removeExpiredAnnouncements() { announcementService.removeExpiredAnnouncements(); } }
#### 6. 应用主类
java package com.example.oamodule;
import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;
SpringBootApplication public class OaNotificationModuleApplication { public static void main(String[] args) { SpringApplication.run(OaNotificationModuleApplication.class, args); } }
#### 7. application.properties 配置文件
properties spring.datasource.urljdbc:mysql://localhost:3306/oamodule spring.datasource.usernameroot spring.datasource.passwordpassword spring.jpa.hibernate.ddl-autoupdate
spring.mail.hostsmtp.example.com spring.mail.port587 spring.mail.usernameyour-emailexample.com spring.mail.passwordyour-email-password spring.mail.properties.mail.smtp.authtrue spring.mail.properties.mail.smtp.starttls.enabletrue
#### 8. 数据库初始化脚本
sql CREATE DATABASE oamodule;
USE oamodule;
CREATE TABLE announcements ( id VARCHAR(50) PRIMARY KEY, type VARCHAR(10), content TEXT, publish_time TIMESTAMP, expiry_time TIMESTAMP );
#### 9. pom.xml 示例
