估计跟这2种日期格式不一样有关系

public static int compareNumberByte(byte[] b1, byte[] b2) {
if(b1 == null || b1.length == 0)
return -1;
else if(b2 == null || b2.length == 0)
return 1;
boolean isNegetive = b1[0] == 45 || b2[0] == 45;
if (isNegetive == false && b1.length != b2.length) {
return b1.length - b2.length;
}
int len = b1.length > b2.length ? b2.length : b1.length;
int result = 0;
int index = -1;
for (int i = 0; i < len; i++) {
int b1val = b1[i];
int b2val = b2[i];
if (b1val > b2val) {
result = 1;
index = i;
break;
} else if (b1val < b2val) {
index = i;
result = -1;
break;
}
}
if (index == 0) {
// first byte compare
return result;
} else {
if( b1.length != b2.length ) {

            int lenDelta = b1.length - b2.length;
            return isNegetive ? 0 - lenDelta : lenDelta;

        } else {
            return isNegetive ? 0 - result : result;
        }
    }
}

看了这块的比较逻辑，正数的话，只比较长度？？ 这个逻辑有问题呀

你可以修复下试试
