Json 从映射中删除密钥

下面的json类型为java.util.HashMap

jsonRequest=[noOfMembers:2, coverageYear:2017, zipCode:99123, premiumList:[[Premium:203.05, Id:1000101], [Premium:205.36, Id:1000102], [Premium:207.67, Id:1000103], [Premium:209.98, Id:1000104], [Premium:212.29, Id:1000105]], members:[[id:5487, age:34, gender:M], [id:5488, age:32, gender:F]]]

我试图通过在groovy中使用jsonRequest=jsonRequest.remove（“premiumList”）从下面的映射中删除premiumList

当我打印jsonRequest时，它将输出显示为

[{Premium=203.05, Id=1000101}, {Premium=205.36, Id=1000102}, {Premium=207.67, Id=1000103}, {Premium=209.98, Id=1000104}, {Premium=212.29, Id=1000105}]

如何在groovy中从映射中删除整个premiumList？

即使您的

java.util.HashMap

是

HashMap

并且您试图删除一个键，您也需要知道您的

jsonRequest

来自哪里。AFIK，您试图从请求中删除不允许删除的密钥

def jsonRequest = [noOfMembers:2, coverageYear:2017, zipCode:99123, premiumList:[[Premium:203.05, Id:1000101], [Premium:205.36, Id:1000102], [Premium:207.67, Id:1000103], [Premium:209.98, Id:1000104], [Premium:212.29, Id:1000105]], members:[[id:5487, age:34, gender:M], [id:5488, age:32, gender:F]]]
​def output = [:] << jsonRequest

output.remove('premiumList')​

def jsonRequest=[noOfMembers:2，保险年度：2017，zipCode:99123，premiumList:[[Premium:203.05，Id:1000101]，[Premium:205.36，Id:1000102]，[Premium:207.67，Id:1000103]，[Premium:209.98，Id:1000104]，[Premium:212.29，Id:1000105]，[Id:5487，年龄：34，性别：M]，[Id:5488，年龄：32，性别：F]]

jsonRequest
是不可变的
java.util.HashMap
是100%可变的。现在Monica可能认为Groovy中的映射是不可变的，这是不正确的。@fsi你怎么知道
