Question

我在尝试将对象保存到数据库时遇到了一个相当奇怪的错误。在尝试保存基类对象时，代码已经完成了，但现在我正在尝试保存从基类域继承的域类。

这是父类：

package com.twc.fatcaone

class Record {

long batchID

}

和我想要保存的子类：

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"
}
}

我的服务中尝试执行保存的代码：

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
                       }

以及尝试进行保存时出现的错误：

Answer 1

不应该是一个小写的＆＃39; a＆＃39;在调用保存函数之前的单词AccountRecord中？

Grails无法保存对象
