Groovy中获取JSON所有索引值及多条件过滤问题求助

问题1：获取所有符合条件的BoundId值 #

原代码仅针对RenewalDetails数组的第一个元素取值，要适配未知数量的响应块，需要遍历整个RenewalDetails数组，同时处理每个元素下的Itemdetails，收集所有符合条件的BoundId。可以用collectMany扁平化嵌套列表，再过滤目标项。

问题2：添加FamilyCode过滤条件 #

在原有travelID长度为33的判断基础上，新增itemDetail.FamilyCode == "PREMIUM"的条件即可。

修改后的完整代码 #

// 解析JSON响应体
def parsedData = new groovy.json.JsonSlurper().parseText('{"data":{"RenewalDetails":[{"ExpiryDetails":{"duration":"xxxxx","destination":"LHR","from":"AUH","value":2,"segments":[{"valudeid":"xxx-xx6262-xxxyyy-1111-11-11-1111"}]},"Itemdetails":[{"BoundId":"Value1","isexpired":true,"FamilyCode":"PREMIUM","availabilityDetails":[{"travelID":"AAA-AB1234-AAABBB-2022-11-10-1111","quota":"X","scale":"XXX","class":"X"}]}]},{"ExpiryDetails":{"duration":"xxxxx","destination":"LHR","from":"AUH","value":2,"segments":[{"valudeid":"xxx-xx6262-xxxyyy-1111-11-11-1111"}]},"Itemdetails":[{"BoundId":"Value2","isexpired":true,"FamilyCode":"PREMIUM","availabilityDetails":[{"travelID":"AAA-AB1234-AAABBB-2022-11-10-1111","quota":"X","scale":"XXX","class":"X"}]}]}],"warnings":[{"code":"xxxx","detail":"xxxxxxxx","title":"xxxxxxxx"}]}')

// 收集所有符合双条件的BoundId
def allBoundIds = parsedData.data.RenewalDetails.collectMany { renewal ->
    renewal.Itemdetails.findAll { itemDetail ->
        itemDetail.FamilyCode == "PREMIUM" && 
        itemDetail.availabilityDetails[0].travelID.length() == 33
    }*.BoundId
}

// 输出结果
println "符合条件的BoundId列表：" + allBoundIds

代码说明 #

• collectMany：遍历每个RenewalDetails元素，将各元素下的Itemdetails处理结果合并为扁平列表，避免嵌套结构。
• findAll：筛选同时满足FamilyCode匹配、travelID长度要求的Itemdetails项。
• *.BoundId：从筛选后的项中批量提取BoundId值。
