// 确保 param 非 null若参数为nulleq条件可能被忽略导致查询无参数。调试 SQL 日志启用 MyBatis SQL 日志检查最终生成的 SQL 是否包含参数# application.yml logging: level: org.mybatis: DEBUG观察控制台输出的 SQL 语句确认参数是否被替换为占位符?并传递。检查参数类型匹配确保参数类型与数据库字段类型兼容。例如字符串参数需用引号包裹-- XML 或注解中 WHERE column #{param} -- 自动处理类型若为数值类型避免误用字符串占位符。确认方法调用检查调用自定义查询时是否实际传入了参数// 错误示例未传递参数 mapper.query(null); // 正确示例 mapper.query(value);通过以上步骤逐一排查通常可定位参数未传递的原因。avg.163.com/topic/detail/8004198avg.163.com/topic/detail/8004199avg.163.com/topic/detail/8004196avg.163.com/topic/detail/8004201avg.163.com/topic/detail/8004200avg.163.com/topic/detail/8004197avg.163.com/topic/detail/8004193avg.163.com/topic/detail/8004191avg.163.com/topic/detail/8004192avg.163.com/topic/detail/8004190avg.163.com/topic/detail/8004195avg.163.com/topic/detail/8004188avg.163.com/topic/detail/8004189avg.163.com/topic/detail/8004187avg.163.com/topic/detail/8004186avg.163.com/topic/detail/8004185avg.163.com/topic/detail/8004184avg.163.com/topic/detail/8004182avg.163.com/topic/detail/8004183avg.163.com/topic/detail/8004180avg.163.com/topic/detail/8004168avg.163.com/topic/detail/8004161avg.163.com/topic/detail/8004163avg.163.com/topic/detail/8004159avg.163.com/topic/detail/8004167avg.163.com/topic/detail/8004165avg.163.com/topic/detail/8004157avg.163.com/topic/detail/8004158avg.163.com/topic/detail/8004166avg.163.com/topic/detail/8004162avg.163.com/topic/detail/8004153avg.163.com/topic/detail/8004160avg.163.com/topic/detail/8004164avg.163.com/topic/detail/8004155avg.163.com/topic/detail/8004156avg.163.com/topic/detail/8004152avg.163.com/topic/detail/8004151avg.163.com/topic/detail/8004150avg.163.com/topic/detail/8004149avg.163.com/topic/detail/8004148avg.163.com/topic/detail/8004108avg.163.com/topic/detail/8004106avg.163.com/topic/detail/8004111avg.163.com/topic/detail/8004110avg.163.com/topic/detail/8004112avg.163.com/topic/detail/8004109avg.163.com/topic/detail/8004100avg.163.com/topic/detail/8004099avg.163.com/topic/detail/8004097avg.163.com/topic/detail/8004103avg.163.com/topic/detail/8004104avg.163.com/topic/detail/8004101avg.163.com/topic/detail/8004105avg.163.com/topic/detail/8004095avg.163.com/topic/detail/8004096avg.163.com/topic/detail/8004098avg.163.com/topic/detail/8004094avg.163.com/topic/detail/8004093avg.163.com/topic/detail/8004092avg.163.com/topic/detail/8004090avg.163.com/topic/detail/8004036avg.163.com/topic/detail/8004037avg.163.com/topic/detail/8004034avg.163.com/topic/detail/8004032avg.163.com/topic/detail/8004029avg.163.com/topic/detail/8004027avg.163.com/topic/detail/8004024avg.163.com/topic/detail/8004028avg.163.com/topic/detail/8004025avg.163.com/topic/detail/8004039avg.163.com/topic/detail/8004035avg.163.com/topic/detail/8004038avg.163.com/topic/detail/8004033avg.163.com/topic/detail/8004031avg.163.com/topic/detail/8004026avg.163.com/topic/detail/8004021avg.163.com/topic/detail/8004022avg.163.com/topic/detail/8004023avg.163.com/topic/detail/8004020avg.163.com/topic/detail/8004019avg.163.com/topic/detail/8003887avg.163.com/topic/detail/8003883avg.163.com/topic/detail/8003885avg.163.com/topic/detail/8003900avg.163.com/topic/detail/8003898avg.163.com/topic/detail/8003899avg.163.com/topic/detail/8003897avg.163.com/topic/detail/8003895avg.163.com/topic/detail/8003894avg.163.com/topic/detail/8003892avg.163.com/topic/detail/8003893avg.163.com/topic/detail/8003891avg.163.com/topic/detail/8003889avg.163.com/topic/detail/8003890avg.163.com/topic/detail/8003888avg.163.com/topic/detail/8003886avg.163.com/topic/detail/8003882avg.163.com/topic/detail/8003884avg.163.com/topic/detail/8003880avg.163.com/topic/detail/7943799avg.163.com/topic/detail/7943820avg.163.com/topic/detail/7943847avg.163.com/topic/detail/8003513avg.163.com/topic/detail/7943766avg.163.com/topic/detail/7943776avg.163.com/topic/detail/7943794avg.163.com/topic/detail/7943818avg.163.com/topic/detail/7943843avg.163.com/topic/detail/8003522avg.163.com/topic/detail/7943787avg.163.com/topic/detail/7943803avg.163.com/topic/detail/7943830avg.163.com/topic/detail/7943854avg.163.com/topic/detail/7943880avg.163.com/topic/detail/8003512avg.163.com/topic/detail/7943765avg.163.com/topic/detail/7943775avg.163.com/topic/detail/7943771avg.163.com/topic/detail/7943796avg.163.com/topic/detail/7943790avg.163.com/topic/detail/7943813avg.163.com/topic/detail/7943834avg.163.com/topic/detail/7943865avg.163.com/topic/detail/7943861avg.163.com/topic/detail/8003508avg.163.com/topic/detail/8003506avg.163.com/topic/detail/7943767avg.163.com/topic/detail/7943774avg.163.com/topic/detail/7943792avg.163.com/topic/detail/7943812avg.163.com/topic/detail/7943837avg.163.com/topic/detail/8003507avg.163.com/topic/detail/7943783avg.163.com/topic/detail/7943805avg.163.com/topic/detail/7943826avg.163.com/topic/detail/7943883avg.163.com/topic/detail/8003505avg.163.com/topic/detail/7943798avg.163.com/topic/detail/7943817avg.163.com/topic/detail/7943846avg.163.com/topic/detail/7943871avg.163.com/topic/detail/7943901avg.163.com/topic/detail/8003502
