在Java中结合大小球盘口进行判断，通常用于体育博彩数据分析或赛事预测场景,以下是完整的实现思路和代码案例：

核心概念

大小球盘口（Over/Under）指博彩公司预设的总进球数（如2.5球），玩家预测实际总进球数高于（大球）或低于（小球）该盘口。

基础数据模型

import lombok.Data;
import java.math.BigDecimal;
import java.time.LocalDateTime;
import java.util.List;
@Data
public class MatchData {
    private String matchId;
    private String homeTeam;
    private String awayTeam;
    private LocalDateTime matchTime;
    // 盘口数据
    private BigDecimal overUnderLine;  // 盘口线（如2.5）
    private BigDecimal overOdds;       // 大球赔率
    private BigDecimal underOdds;      // 小球赔率
    // 历史数据
    private List<TeamStats> homeRecentStats;
    private List<TeamStats> awayRecentStats;
    // 实时数据
    private Integer currentHomeScore;
    private Integer currentAwayScore;
    private LocalDateTime matchStartTime;
    private Integer currentMinute;
}
@Data
public class TeamStats {
    private String teamName;
    private Integer goalsScored;
    private Integer goalsConceded;
    private LocalDateTime matchDate;
    // 其他相关统计
}

盘口判断核心逻辑
