实现公告的功能需要前端和后端配合完成,在此我提供一种使用Spring Boot和Vue.js实现公告的思路。
1. 后端实现
使用Spring Boot开发后端,需要定义公告的数据模型,如:
```java
@Entity
@Table(name = "announcement")
public class Announcement {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String title;
private String content;
@Column(name = "create_time")
private Date createTime;
// getter 和 setter 方法
}
```
然后,使用Spring Data JPA来访问数据库,定义对应的Repository:
```java
public interface AnnouncementRepository extends JpaRepository<Announcement, Long> {
List<Announcement> findAllByOrderByCreateTimeDesc();
}
```
在Controller中,提供查询公告列表和新增公告的接口:
```java
@RestController
@RequestMapping("/api/announcement")
public class AnnouncementController {
@Autowired
private AnnouncementRepository repository;
@GetMapping("/list")
public List<Announcement> list() {
return repository.findAllByOrderByCreateTimeDesc();
}
@PostMapping("/add")
public Announcement add(@RequestBody Announcement announcement) {
announcement.setCreateTime(new Date());
return repository.save(announcement);
}
}
```
2. 前端实现
使用Vue.js开发前端,通过axios库访问后端API,实现公告的展示和添加功能。
在Vue组件中,使用data属性存储公告列表和新增公告的表单数据:
```javascript
data() {
return {
announcements: [],
newAnnouncement: {
title: '',
content: ''
}
}
},
```
在created钩子函数中,使用axios库获取公告列表:
```javascript
created() {
axios.get('/api/announcement/list').then(response => {
this.announcements = response.data
})
},
```
在模板中,使用v-for指令渲染公告列表:
```html
<template>
<div>
<h2>公告列表</h2>
<div v-for="announcement in announcements" :key="announcement.id">
<h3>{{ announcement.title }}</h3>
<p>{{ announcement.content }}</p>
<small>{{ announcement.createTime }}</small>
</div>
<h2>新增公告</h2>
<form @submit.prevent="addAnnouncement">
<div>
<label>标题:</label>
<input v-model="newAnnouncement.title" type="text" />
</div>
<div>
<label>内容:</label>
<textarea v-model="newAnnouncement.content"></textarea>
</div>
<button type="submit">提交</button>
</form>
</div>
</template>
```
在methods属性中,定义addAnnouncement方法,通过axios库向后端API发送POST请求,添加新公告:
```javascript
methods: {
addAnnouncement() {
axios.post('/api/announcement/add', this.newAnnouncement).then(response => {
this.announcements.unshift(response.data)
this.newAnnouncement.title = ''
this.newAnnouncement.content = ''
})
}
}
```
以上就是使用Spring Boot和Vue.js实现公告的思路,具体实现细节可以根据实际情况进行调整。
