我有 2 个 hashmap 对象，ctx.vars.hashOld并且ctx.vars.hashNew包含：

分别。它们包含相同的键，但具有不同的值。我正在尝试计算同一键的值之间的差异，但是null在使用一个对象的键作为获取另一个对象的值的输入时获取值：

Map mapNew = ctx.vars.hashNew;
Map mapOld = ctx.vars.hashOld;
def test = [];
for (def key : mapNew.keySet()){
  def valNew = mapNew.get(key);
  def valOld = mapOld.get(key);
  test.add([valOld, valNew]);
}

我会得到这样的东西test：

{0=[null, 18430105], 1=[null, 6030912], 2=[null, 6215465], 3=[null, 17935050], 4=[null, 23497940], 5=[null, 23179579], 6 =[null, 15834156], 7=[null, 6072952], 8=[null, 42790683], 9=[null, 57462519], 10=[null, 82151687], 11=[null, 1487951], 12=[空, 14163152], 13=[空, 30413191], 14=[空, 22081784], 15=[空, 1942286], 16=[空, 33413054], 17=[空, 12327906], 18=[空, 23921212], 19=[null, 5682918], 20=[null, 38564796], 21=[null, 34909797], 22=[null, 20613344], 23=[null, 4302495], 24=[null, 24699429] , 25=[null, 8878420], 26=[null, 8532763]}

即使mapOld肯定有相同的键mapNew。关于为什么会发生这种情况的任何想法？

更新我实际上是在将一个 StringBuilder 对象传递给密钥。使用 更改为字符串类型toString()。除此之外，我没有使用来自 的键keySet()，而是将它们放入单独的字符串列表中并使用它，现在我看到了想要的结果。
