Java在剪辑接单报价比价系统源码开发中发挥着核心作用,以下从技术架构、核心功能、源码实现及优势等维度进行深度解析:
报价计算服务
java
@Service public class QuotationService { @Autowired private QuotationRepository quotationRepository; @Autowired private MarketTrendService marketTrendService; @Autowired private TemplateRepository templateRepository; public BigDecimal calculateQuotation(Project project, Map<String, Object> params) { QuotationModel model = QuotationModel.load(); BigDecimal predictedPrice = model.predict(project, params); MarketTrend trend = marketTrendService.getCurrentTrend(); BigDecimal adjustedPrice = predictedPrice.multiply(trend.getAdjustmentFactor()); Template template = templateRepository.findByUserId(project.getClientId()); if (template != null) { adjustedPrice = template.apply(adjustedPrice); } if (adjustedPrice.compareTo(project.getBudget()) > 0) { throw new QuotationException("报价超出预算"); } return adjustedPrice.setScale(2, RoundingMode.HALF_UP); } }比价分析服务
java
@Service public class ComparisonService { @Autowired private QuotationRepository quotationRepository; @Autowired private ReviewRepository reviewRepository; public List<ComparisonResult> compareQuotations(Long projectId) { List<Quotation> quotations = quotationRepository.findByProjectId(projectId); return quotations.stream() .map(quotation -> { Double avgRating = reviewRepository.avgRatingByUserId(quotation.getUserId()); Double score = calculateCompositeScore(quotation.getPrice(), avgRating, quotation.getHistoryPrice()); return new ComparisonResult(quotation, score); }) .sorted(Comparator.comparingDouble(ComparisonResult::getScore).reversed()) .collect(Collectors.toList()); } private Double calculateCompositeScore(BigDecimal price, Double rating, BigDecimal historyPrice) { // 综合得分计算逻辑(价格、评分、历史成交价等维度) return 0.4 * (1 - price.doubleValue() / 10000) + 0.4 * rating + 0.2 * (1 - historyPrice.doubleValue() / 5000); } }
