关于评价功能，每评价一条就会for循环很多条相同的数据
相关代码：
<van-action-sheet v-model:show="state.dialogVisible" :title="book.bookName">
<van-form ref="evaluationForm">
<van-cell-group inset>
<van-rate v-model="form.score" color="#ffd21e" void-icon="star" style="padding: 16px" ></van-rate>
<van-field
v-model="form.content"
name="content"
placeholder="这里输入评论内容"
autocomplete = "off"
:rules="[{ required: true, message: '请输入评论内容' }]"
/>
</van-cell-group>
<div style="margin: 16px;margin-bottom: 50px">
<van-button round block type="primary" @click="onSubmit('evaluationForm')">
提交短评
</van-button>
</div>
</van-form>
</van-action-sheet>相关代码：
@PostMapping("/evaluate")
public ResponseUtils evaluate(Long memberId,Long bookId,Integer score,String content){
ResponseUtils resp = null;
try {
Evaluation evaluation = evaluationService.evaluate(memberId, bookId, score, content);
resp = new ResponseUtils().put("evaluation",evaluation);
}catch (Exception e){
e.printStackTrace();
resp = new ResponseUtils(e.getClass().getSimpleName(),e.getMessage());
}
return resp;
}相关代码：
实现类
@Override
public Evaluation evaluate(Long memberId, Long bookId, Integer score, String content) {
Evaluation evaluation = new Evaluation();
evaluation.setMemberId(memberId);
evaluation.setBookId(bookId);
evaluation.setScore(score);
evaluation.setContent(content);
evaluation.setCreateTime(new Date());
evaluation.setState("enable");
evaluation.setEnjoy(0);
evaluationMapper.insert(evaluation);
return evaluation;

同学你好，1、测试同学代码是没有问题的，建议同学查看数据库中短评信息，查看是否是数据库中的问题。
2、也有可能是同学查询的问题，同学也可以将代码反馈到问答区。如下所示：将对应的代码反馈到对应的代码格式中。
祝学习愉快！
