我試圖做一個DIFF，它不看我的JSON值的順序。 我試著在diff前用import com.fasterxml.jackson.databind.ObjectMapper對我的json進行排序，但無論是SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS還是MapperFeature.SORT_PROPERTIES_ALPHABETICALLY的排序都不符合我的要求。 有誰知道另一種方法可以按字母值（NB_SUP_HET, NB_SUP_SOL, WEI_MAX）對我的json進行排序？

uj5u.com熱心網友回復：
我嘗試了另一個解決方案，即通過一個遞回函式對JsonSlurper()物件進行排序。 但這是一個復雜的物件，似乎由LinkedHashMap、ArrayList、LazyMap......組成，因此很難使其作業。
有人知道如何輕松地進行排序嗎？
這是我的代碼，試試......
def sortSubMap（def root, String keyToSort） {
root.each {
KeywordUtil.logInfo(") inspect:" it.expect())
KeywordUtil.logInfo("it" it.getClass())
KeywordUtil.logInfo("it.value" it.value.getClass())
if (it.key==keyToSort) {
KeywordUtil.logInfo("*** it.key==keyToSort"/span>)
//TODO :讓我們對這個節點的元素 "keyToSort "進行排序，并替換到json_obj中。
} else if ( it.value instanceof groovy.json.internal.LazyMap) {
KeywordUtil.logInfo("on recurse LazyMap"/span>)
it.each { it1 -> sortSubMap(it1, keyToSort) }
sortSubMap(it.value, keyToSort)
} else if (it.value instanceof ArrayList) {
KeywordUtil.logInfo("on recurse ArrayList"/span>)
KeywordUtil.logInfo("it.value : "/span> it.value)
sortSubMap(it.value, keyToSort)
}
}

作為參考，我終于成功地將我的 "extra_data_value_list "按 "extra_data_item_code "的值按字母順序排序
。這里是用這些奇怪的封閉函式產生的遞回函式:) :
