springboot+mysql+vue3 评论敏感词屏蔽功能具体实现

评论敏感词屏蔽功能可以通过以下步骤实现:
1. 在 MySQL 数据库中创建一个敏感词表,用于存储所有需要屏蔽的敏感词。
2. 在 Spring Boot 中使用 MyBatis 或 JPA 等框架,将敏感词表映射为一个实体类,并创建一个 DAO 层用于操作该表。
3. 在后端编写一个过滤器,用于过滤评论中的敏感词。过滤器可以在评论提交到后端之前进行拦截,并根据敏感词表进行屏蔽。
4. 在前端使用 Vue3,通过 AJAX 请求将评论提交到后端,并接收后端返回的结果。如果评论中包含敏感词,前端可以弹出提示框进行提醒。
下面是一个简单的示例代码,仅供参考:
MySQL敏感词表:
```sql
CREATE TABLE `sensitive_words` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`word` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
```
Spring Boot 实体类:
```java
@Entity
@Table(name = "sensitive_words")
public class SensitiveWord {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
@Column(name = "word")
private String word;
// getter 和 setter 方法
}
```
Spring Boot DAO 层:
```java
@Repository
public interface SensitiveWordDao extends JpaRepository<SensitiveWord, Integer> {
List<SensitiveWord> findAll();
}
```
Spring Boot 过滤器:
```java
@WebFilter(filterName = "sensitiveWordFilter", urlPatterns = "/comment/*")
public class SensitiveWordFilter implements Filter {
private List<String> sensitiveWords = new ArrayList<>();
@Autowired
private SensitiveWordDao sensitiveWordDao;
@Override
public void init(FilterConfig filterConfig) throws ServletException {
List<SensitiveWord> words = sensitiveWordDao.findAll();
for (SensitiveWord word : words) {
sensitiveWords.add(word.getWord());
}
}
@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
HttpServletRequest httpRequest = (HttpServletRequest) request;
String comment = httpRequest.getParameter("comment");
for (String word : sensitiveWords) {
if (comment.contains(word)) {
HttpServletResponse httpResponse = (HttpServletResponse) response;
httpResponse.setStatus(400);
httpResponse.getWriter().write("评论中包含敏感词");
return;
}
}
chain.doFilter(request, response);
}
@Override
public void destroy() {
}
}
```
Vue3 组件:
```vue
<template>
<div>
<textarea v-model="comment"></textarea>
<button @click="submitComment">提交</button>
</div>
</template>
<script>
import axios from 'axios';
export default {
data() {
return {
comment: ''
}
},
methods: {
submitComment() {
axios.post('/comment', {
comment: this.comment
}).then(response => {
alert('评论成功');
}).catch(error => {
alert(error.response.data);
});
}
}
}
</script>
```
