嘗試將對象保存到我的數據庫時，出現了一個相當奇怪的錯誤。當試圖保存基類對象時，代碼工作的很完善，但現在我試圖保存從基類域類繼承的域類。Grails無法保存對象
這裏是父類：
package com.twc.fatcaone
class Record {
long batchID
}
而且我想救子類：
package com.twc.fatcaone
class AccountRecord extends Record {
long uniqueId
String accountId
String type
String insurance
String currencyType
float amount
String upSerDel
String generalComments
static mapping = {
collection "accountRecords"
database "twcdb"
}
}
在我服務的代碼了試圖做保存：
accountRecordList.each {
def accountRecord = new AccountRecord(batchID: params.selectedBatch.id,
uniqueId: it.uniqueId,
accountId: it.accountId,
type: it.type,
insurance: it.insurance,
currencyType: it.currencyType,
amount: it.amount,
upSerDel: it.upSerDel,
generalComments: it.generalComments)
if (!AccountRecord.save(flush: true, failOnError: true)) {
println "ERROR: Record could not be saved!"
def errorValue = AccountRecord.errors
println errorValue
}
和試圖保存時出現的錯誤：
