判断 + break ?

你自己也说是“重复数据”了

新增2条  不是四条

正确这样日志

这是你程序内部自己的算法问题
自己解决吧，cant help you

我找到原因了，执行第一次数据把第2条也新增了，执行第二次数据把第一次数据的也新增了  ,我还没找到解决方案

这个有问题

			"select * from t_activating_quantity   where  q_createtime in (select max(q_createtime) from t_activating_quantity  $cnd )");
		for (PreinstallApk preinstallApk : preinstallApks) {
			cnd.or("q_apkId", "=", preinstallApk.getId());
			System.err.println("=---1" + cnd.or("q_apkId", "=", preinstallApk.getId()));
		}
		for (Device devices : device) {
			cnd.or("q_deviceId", "=", devices.getId());
			System.err.println("=---" + cnd.or("q_deviceId", "=", devices.getId()));
		}

日志
=---1 WHERE q_apkId=1 OR q_apkId=1
=---1 WHERE q_apkId=1 OR q_apkId=1 OR q_apkId=39 OR q_apkId=39
=--- WHERE q_apkId=1 OR q_apkId=1 OR q_apkId=39 OR q_apkId=39 OR q_deviceId=112 OR q_deviceId=112

System.err.println("=---1" + cnd.or("q_apkId", "=", preinstallApk.getId()));
这句打印语句中的 cnd.or("q_apkId", "=", preinstallApk.getId())
本身会改变cnd

改成这样
System.err.println("=---1" + cnd);

System.err.println("=---1" + cnd);
System.err.println("=---" + cnd);
=---1 WHERE q_apkId=1
=---1 WHERE q_apkId=1 OR q_apkId=39
=--- WHERE q_apkId=1 OR q_apkId=39 OR q_deviceId=112
