我的代码打印错误即使输入是正确的

Question

这是原始代码

if (!isNullOrEmpty(configTypeBuilder.destinationField, RULE_CRITERIA_CONFIG_TYPE_BUILDER_DESTINATION_FIELD_PATH)) {
if (ruleAttributes.firstOrNull { ruleAttribute -> ruleAttribute == destinationField } == null) {
addValidationError(RULE_CRITERIA_CONFIG_TYPE_BUILDER_DESTINATION_FIELD_PATH, configTypeBuilder.destinationField, NOT_EXIST_CONSTRAINT)
}
}

我修改了代码，只是将无效值添加到列表中，然后打印它们，但是现在当我在invalid destinationField后面输入valid destinationField时，它仍然会显示错误消息，我不知道发生了什么

val invalidDestination = hashSetOf<String>()
if (!isNullOrEmpty(configTypeBuilder.destinationField, RULE_CRITERIA_CONFIG_TYPE_BUILDER_DESTINATION_FIELD_PATH)) {
for (destinationField in destinationFieldList) {
if (!ruleAttributes.contains(destinationField)) {
invalidDestination.add(destinationField)
}
}
if (invalidDestination.size > 0) {
addValidationError(
"$RULE_CRITERIA_CONFIG_TYPE_BUILDER_DESTINATION_FIELD_PATH $NOT_EXIST_CONSTRAINT",
DESTINATION,
"$ADD_TAX_ENGINE_ATTRIBUTE_FIELDS $invalidDestination"
)
}
}

如果您的目标是仅在没有有效目标时显示错误消息，则需要在If语句中再添加一个条件。如果没有，请澄清你的问题，并张贴整个功能

条件的例子:

var foundValid = false
for (destinationField in destinationFieldList) {
if (!ruleAttributes.contains(destinationField)) {
invalidDestination.add(destinationField)
}else {
foundValid = true
break //if you need invalidDestination list for later remove this break
}
}
if (invalidDestination.size > 0 && !foundValid) {
...
}
