技术架构全景图
二、投票调查系统数据库设计
核心实体关系设计
Diboot实体类示例
// 问卷实体
@Table(name = "survey")
public class Survey extends BaseEntity {
@TableField("title")
private String title;
@TableField("description")
private String description;
@TableField("start_time")
private LocalDateTime startTime;
@TableField("end_time")
private LocalDateTime endTime;
@TableField("status")
private Integer status;
// 关联查询：问卷包含的问题
@BindEntityList(entity = Question.class, condition = "this.id=survey_id")
private List<Question> questions;
}
// 问题实体
@Table(name = "question")
public class Question extends BaseEntity {
@TableField("survey_id")
private Long surveyId;
@TableField("content")
private String content;
@TableField("type")
private String type; // SINGLE_CHOICE, MULTIPLE_CHOICE, TEXT
// 关联查询：问题的选项
@BindEntityList(entity = Option.class, condition = "this.id=question_id")
private List<Option> options;
}
三、零代码配置投票业务流程
问卷创建流程设计
前端表单配置示例
<template>
<di-form :model="surveyForm" :rules="rules" label-width="120px">
<di-form-item label="问卷标题" prop="title">
<di-input v-model="surveyForm.title" placeholder="请输入问卷标题" />
</di-form-item>
<di-form-item label="问卷描述" prop="description">
<di-rich-editor v-model="surveyForm.description" />
</di-form-item>
<di-form-item label="问题列表">
<di-dynamic-list v-model="surveyForm.questions">
<template #default="{ item, index }">
<question-editor :question="item" :index="index" />
</template>
</di-dynamic-list>
</di-form-item>
</di-form>
</template>
<script setup lang="ts">
import { useForm } from '@/hooks/use-form'
const { form: surveyForm, rules } = useForm({
title: '',
description: '',
questions: []
})
</script>
四、复杂业务逻辑实现方案
投票统计与分析功能
// 投票统计服务
@Service
public class VoteStatisticsService {
@Autowired
private AnswerMapper answerMapper;
@Autowired
private OptionMapper optionMapper;
/**
* 获取问卷统计结果
*/
public SurveyStatistics getSurveyStatistics(Long surveyId) {
SurveyStatistics statistics = new SurveyStatistics();
// 总参与人数
Integer totalParticipants = answerMapper.selectCount(
Wrappers.<Answer>query().eq("survey_id", surveyId)
);
statistics.setTotalParticipants(totalParticipants);
// 各选项投票数统计
List<OptionStatistics> optionStats = optionMapper.selectOptionStatistics(surveyId);
statistics.setOptionStatistics(optionStats);
// 投票趋势分析
List<VoteTrend> voteTrends = answerMapper.selectVoteTrend(surveyId);
statistics.setVoteTrends(voteTrends);
return statistics;
}
}
// 使用Diboot的关联查询简化统计
public interface OptionMapper extends BaseMapper<Option> {
@Select("SELECT o.id, o.content, COUNT(ad.id) as vote_count " +
"FROM option o LEFT JOIN answer_detail ad ON o.id = ad.option_id " +
"WHERE o.question_id IN (SELECT id FROM question WHERE survey_id = #{surveyId}) " +
"GROUP BY o.id, o.content")
List<OptionStatistics> selectOptionStatistics(@Param("surveyId") Long surveyId);
}
实时投票数据大屏
<template>
<div class="statistics-dashboard">
<el-row :gutter="20">
<el-col :span="8">
<stat-card title="总参与人数" :value="statistics.totalParticipants" icon="User" />
</el-col>
<el-col :span="8">
<stat-card title="完成率" :value="completionRate" suffix="%" icon="Success" />
</el-col>
<el-col :span="8">
<stat-card title="实时投票" :value="realtimeVotes" icon="TrendCharts" />
</el-col>
</el-row>
<el-row :gutter="20" style="margin-top: 20px;">
<el-col :span="12">
<vote-trend-chart :data="statistics.voteTrends" />
</el-col>
<el-col :span="12">
<option-distribution-chart :data="statistics.optionStatistics" />
</el-col>
</el-row>
</div>
</template>
<script setup lang="ts">
import { onMounted, ref } from 'vue'
import { useEcharts } from '@/stores/echarts'
import { getSurveyStatistics } from '@/api/vote'
const echartsStore = useEcharts()
const statistics = ref({} as SurveyStatistics)
onMounted(async () => {
const surveyId = route.params.id
statistics.value = await getSurveyStatistics(surveyId)
// 建立WebSocket连接接收实时投票数据
setupRealtimeUpdates(surveyId)
})
</script>
五、移动端与PC端一体化开发
响应式设计策略
移动端投票组件
<template>
<view class="vote-container">
<header-nav title="参与投票" />
<scroll-view scroll-y class="content">
<view class="survey-info">
<text class="title">{{ survey.title }}</text>
<text class="description">{{ survey.description }}</text>
</view>
<view class="questions">
<question-item
v-for="(question, index) in survey.questions"
:key="question.id"
:question="question"
:index="index"
@answer="handleAnswer"
/>
</view>
<view class="submit-section">
<button class="submit-btn" @click="submitVote">提交投票</button>
</view>
</scroll-view>
</view>
</template>
<script setup lang="ts">
import { ref } from 'vue'
import { onLoad } from '@dcloudio/uni-app'
import { getSurveyDetail } from '@/api/mobile/vote'
const survey = ref({} as SurveyDetail)
onLoad(async (options) => {
const surveyId = options.id
survey.value = await getSurveyDetail(surveyId)
})
const handleAnswer = (questionId: number, answer: any) => {
// 处理用户答题
}
const submitVote = async () => {
// 提交投票
await submitSurveyAnswers(survey.value.id, answers.value)
uni.showToast({ title: '投票成功', icon: 'success' })
uni.navigateBack()
}
</script>
六、性能优化与部署实践
数据库查询优化方案
-- 创建优化索引
CREATE INDEX idx_survey_status ON survey(status);
CREATE INDEX idx_answer_survey_user ON answer(survey_id, user_id);
CREATE INDEX idx_answer_detail_answer ON answer_detail(answer_id);
-- 使用覆盖索引优化统计查询
CREATE INDEX idx_option_question ON option(question_id) INCLUDE (content, vote_count);
缓存策略设计
// 使用Redis缓存热门问卷数据
@Service
public class SurveyCacheService {
@Autowired
private RedisTemplate<String, Object> redisTemplate;
private static final String SURVEY_KEY_PREFIX = "survey:";
private static final String STATISTICS_KEY_PREFIX = "stats:";
private static final long SURVEY_CACHE_TIME = 3600; // 1小时
public Survey getSurveyWithCache(Long surveyId) {
String key = SURVEY_KEY_PREFIX + surveyId;
Survey survey = (Survey) redisTemplate.opsForValue().get(key);
if (survey == null) {
survey = surveyMapper.selectById(surveyId);
if (survey != null) {
redisTemplate.opsForValue().set(key, survey, SURVEY_CACHE_TIME, TimeUnit.SECONDS);
}
}
return survey;
}
// 批量获取避免缓存穿透
public Map<Long, Survey> batchGetSurveys(List<Long> surveyIds) {
Map<Long, Survey> result = new HashMap<>();
List<String> keys = surveyIds.stream()
.map(id -> SURVEY_KEY_PREFIX + id)
.collect(Collectors.toList());
List<Object> cached = redisTemplate.opsForValue().multiGet(keys);
// 处理缓存命中与未命中的逻辑
// ...
return result;
}
}
