技术架构深度解析

后端服务架构设计

本平台采用SpringBoot2.7+MyBatisPlus3.5+MySQL8.0构建高可用后端服务。SpringBoot的自动配置特性极大简化了微服务部署流程，而MyBatisPlus的增强CRUD操作则显著提升了数据持久化效率。

// 同城任务发布核心业务实现
@Service
public class TaskPublishService {
    
    @Autowired
    private TaskMapper taskMapper;
    
    /**
     * 基于MyBatisPlus的多条件任务查询
     */
    public Page<TaskVO> getTasksByCondition(TaskQueryDTO query) {
        return taskMapper.selectPage(new Page<>(query.getPage(), query.getSize()),
                Wrappers.<Task>lambdaQuery()
                    .eq(query.getCategoryId() != null, Task::getCategoryId, query.getCategoryId())
                    .like(StringUtils.isNotBlank(query.getKeyword()), Task::getTitle, query.getKeyword())
                    .eq(StringUtils.isNotBlank(query.getCityCode()), Task::getCityCode, query.getCityCode())
                    .eq(Task::getStatus, TaskStatus.ACTIVE));
    }
    
    /**
     * 企业实名认证状态校验
     */
    @Transactional
    public boolean publishEnterpriseTask(EnterpriseTaskDTO taskDTO) {
        // 验证企业认证状态
        EnterpriseAuth auth = enterpriseAuthMapper.selectOne(
                Wrappers.<EnterpriseAuth>lambdaQuery()
                    .eq(EnterpriseAuth::getUserId, taskDTO.getUserId())
                    .eq(EnterpriseAuth::getStatus, AuthStatus.APPROVED));
        
        if (auth == null) {
            throw new BusinessException("企业未完成实名认证");
        }
        
        Task task = TaskConverter.INSTANCE.toEntity(taskDTO);
        return taskMapper.insert(task) > 0;
    }
}

数据库表结构设计采用规范化与反规范化结合的策略，确保数据一致性的同时优化查询性能：

-- 同城任务核心表结构
CREATE TABLE `t_task` (
  `id` BIGINT NOT NULL AUTO_INCREMENT,
  `title` VARCHAR(200) NOT NULL COMMENT '任务标题',
  `category_id` INT NOT NULL COMMENT '分类ID',
  `city_code` VARCHAR(20) NOT NULL COMMENT '城市编码',
  `lng` DECIMAL(10,6) COMMENT '经度',
  `lat` DECIMAL(10,6) COMMENT '纬度',
  `enterprise_id` BIGINT COMMENT '企业ID',
  `budget` DECIMAL(10,2) COMMENT '任务预算',
  `status` TINYINT DEFAULT 1 COMMENT '任务状态',
  `create_time` DATETIME DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`id`),
  KEY `idx_city_category` (`city_code`,`category_id`),
  KEY `idx_location` (`lng`,`lat`),
  KEY `idx_enterprise` (`enterprise_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 企业认证信息表
CREATE TABLE `t_enterprise_auth` (
  `id` BIGINT NOT NULL AUTO_INCREMENT,
  `user_id` BIGINT NOT NULL,
  `company_name` VARCHAR(200) NOT NULL,
  `business_license` VARCHAR(100) NOT NULL,
  `auth_status` TINYINT DEFAULT 0 COMMENT '认证状态',
  `auth_time` DATETIME COMMENT '认证时间',
  PRIMARY KEY (`id`),
  UNIQUE KEY `uk_user_id` (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

跨平台移动端架构

用户端采用UniApp框架开发，实现Android与iOS双端代码统一。基于Vue3的Composition API构建响应式业务逻辑，有效提升开发效率与代码可维护性。

        <view v-for="category in categories" :key="category.id"
              class="category-item" @tap="selectCategory(category)">
          <image :src="category.icon" class="category-icon"></image>
          <text class="category-name">{{ category.name }}</text>
        </view>
      </scroll-view>
    </view>
    
    <view class="form-section">
      <input class="title-input" v-model="taskForm.title" 
             placeholder="请输入任务标题" maxlength="50" />

      </view>
    </view>
    
    <button class="publish-btn" @tap="handlePublish" 
            :disabled="!publishable">发布任务</button>
  </view>
</template>

<script setup>
import { ref, computed, onMounted } from 'vue'
import { useStore } from 'vuex'

const store = useStore()
const location = ref({ lat: 39.90923, lng: 116.397428 })
const categories = ref([])
const taskForm = ref({
  title: '',
  categoryId: null,
  description: '',
  budget: '',
  location: null
})

// 计算属性验证表单可发布状态
const publishable = computed(() => {
  return taskForm.value.title.length > 5 && 
         taskForm.value.categoryId && 
         taskForm.value.budget > 0
})

// 选择地理位置
const chooseLocation = async () => {
  const result = await uni.chooseLocation({
    latitude: location.value.lat,
    longitude: location.value.lng
  })
  
  if (result) {
    location.value = { lat: result.latitude, lng: result.longitude }
    taskForm.value.location = result.address
  }
}

// 处理任务发布
const handlePublish = async () => {
  if (!publishable.value) return
  
  try {
    await store.dispatch('task/publishTask', {
      ...taskForm.value,
      ...location.value
    })
    uni.showToast({ title: '发布成功', icon: 'success' })
    setTimeout(() => uni.navigateBack(), 1500)
  } catch (error) {
    uni.showToast({ title: '发布失败', icon: 'none' })

核心功能模块技术实现

谷歌地图深度集成

平台通过谷歌地图JavaScript API实现精准地理位置服务，支持任务位置标记、范围搜索、路径规划等高级功能。

// 地图服务封装类
export class GoogleMapService {
  constructor(apiKey) {
    this.apiKey = apiKey
    this.map = null
    this.markers = []
  }
  
  // 初始化地图
  initMap(container, center, zoom = 12) {
    return new Promise((resolve) => {
      this.map = new google.maps.Map(container, {
        center: center,
        zoom: zoom,
        mapTypeControl: false,
        streetViewControl: false
      })
      
      google.maps.event.addListenerOnce(this.map, 'idle', () => {
        resolve(this.map)
      })
    })
  }
  
  // 添加任务标记点
  addTaskMarker(task, onClick) {
    const marker = new google.maps.Marker({
      position: { lat: task.lat, lng: task.lng },
      map: this.map,
      title: task.title,
      icon: this.getMarkerIcon(task.category)
    })
    
    marker.addListener('click', () => {
      onClick(task)
    })
    
    this.markers.push(marker)
    return marker
  }
  
  // 基于地理位置的半径搜索
  searchInRadius(center, radius, tasks) {
    const geofilter = new GeoFilter(center, radius)
    return tasks.filter(task => 
      geofilter.contains({ lat: task.lat, lng: task.lng })
    )
  }
}

智能分类与推荐系统

平台采用多级分类体系结合协同过滤算法，实现任务的精准分类与个性化推荐。

// 分类推荐服务
@Service
public class CategoryRecommendService {
    
    @Autowired
    private UserBehaviorMapper userBehaviorMapper;
    
    /**
     * 基于用户行为的分类推荐
     */
    public List<CategoryVO> recommendCategories(Long userId, String cityCode) {
        // 获取用户历史行为
        List<UserBehavior> behaviors = userBehaviorMapper.selectList(
                Wrappers.<UserBehavior>query()
                    .eq("user_id", userId)
                    .orderByDesc("create_time")
                    .last("limit 100"));
        
        // 计算分类权重
        Map<Integer, Double> categoryWeights = calculateCategoryWeights(behaviors);
        
        // 结合城市热门分类
        Map<Integer, Double> hotCategories = getHotCategoriesByCity(cityCode);
        
        // 融合权重计算
        return mergeAndSortCategories(categoryWeights, hotCategories);
    }
    
    private Map<Integer, Double> calculateCategoryWeights(List<UserBehavior> behaviors) {
        Map<Integer, Double> weights = new HashMap<>();
        long now = System.currentTimeMillis();
        
        for (UserBehavior behavior : behaviors) {
            double timeDecay = calculateTimeDecay(now, behavior.getCreateTime().getTime());
            double behaviorWeight = getBehaviorWeight(behavior.getType());
            
            double score = timeDecay * behaviorWeight;
            weights.merge(behavior.getCategoryId(), score, Double::sum);
        }
        
        return weights;
    }
}

企业认证与店铺管理

企业实名认证采用多级审核机制，确保平台商户质量与交易安全。

// 企业认证服务
@Service
@Transactional
public class EnterpriseAuthService {
    
    @Autowired
    private EnterpriseAuthMapper enterpriseAuthMapper;
    
    @Autowired
    private StorageService storageService;
    
    /**
     * 提交企业认证申请
     */
    public boolean submitAuth(EnterpriseAuthDTO authDTO) {
        // 验证营业执照唯一性
        Long exists = enterpriseAuthMapper.selectCount(
                Wrappers.<EnterpriseAuth>query()
                    .eq("business_license", authDTO.getBusinessLicense())
                    .ne("status", AuthStatus.REJECTED));
        
        if (exists > 0) {
            throw new BusinessException("营业执照已被使用");
        }
        
        // 上传营业执照图片
        String licenseUrl = storageService.uploadFile(authDTO.getLicenseImage());
        
        EnterpriseAuth auth = EnterpriseAuth.builder()
                .userId(authDTO.getUserId())
                .companyName(authDTO.getCompanyName())
                .businessLicense(authDTO.getBusinessLicense())
                .licenseUrl(licenseUrl)
                .contactName(authDTO.getContactName())
                .contactPhone(authDTO.getContactPhone())
                .status(AuthStatus.PENDING)
                .submitTime(new Date())
                .build();
        
        return enterpriseAuthMapper.insert(auth) > 0;
    }
    
    /**
     * 审核企业认证
     */
    public boolean reviewAuth(Long authId, AuthStatus status, String remark) {
        EnterpriseAuth auth = enterpriseAuthMapper.selectById(authId);
        if (auth == null) {
            throw new BusinessException("认证记录不存在");
        }
        
        auth.setStatus(status);
        auth.setReviewTime(new Date());
        auth.setReviewRemark(remark);
        
        // 如果审核通过，创建店铺
        if (status == AuthStatus.APPROVED) {
            createEnterpriseShop(auth);
        }
        
        return enterpriseAuthMapper.updateById(auth) > 0;
    }
}

// 缓存配置与优化
@Configuration
@EnableCaching
public class CacheConfig {
    
    @Bean
    public RedisCacheManager cacheManager(RedisConnectionFactory factory) {
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofMinutes(30))
                .disableCachingNullValues()
                .serializeKeysWith(RedisSerializationContext.SerializationPair
                        .fromSerializer(new StringRedisSerializer()))
                .serializeValuesWith(RedisSerializationContext.SerializationPair
