Watcher 中的空哈希映射值

问题描述

我有 2 个 hashmap 对象，ctx.vars.hashOld 和 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得 null 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]);
}

我会在 test 中得到类似的信息：

{0=[null,18430105],1=[null,6030912],2=[null,6215465],3=[null,17935050],4=[null,23497940],5=[null,29317] ],6=[null,15834156],7=[null,6072952],8=[null,42790683],9=[null,57462519],10=[null,82151687],14=[null,42790683] 12=[null,14163152],13=[null,30413191],22081784],15=[null,1942286],16=[null,33413054],17=[null,27,80] [null,23921212],19=[null,5682918],20=[null,38564796],21=[null,34909797],22=[null,20613344],23=[null,4302],24699429],25=[null,8878420],26=[null,8532763]}

尽管 mapOld 肯定具有与 mapNew 相同的键。关于为什么会发生这种情况的任何想法？

UPDATE 我实际上是将一个 StringBuilder 对象传递到键中。使用 toString() 更改为字符串类型。除此之外，我没有使用 keySet() 中的键，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。
