ローカル環境では一切問題がないが、AWS Lambda 上で動かすと下記エラーが発生した。

エラーとなっているサービスは、GormServiceのクラス。
原因は、@Service annotation を使っていたサービスで一部実装部分があったため、abstract class として利用していたのが原因。

@Service を利用する箇所は全て interface を利用し実装部分は普通の class を作成してそこに記載するようにした。

忘れがちなので備忘録として


class DomainA implements GormEntity<DomainA> {
    static belongsTo = DomainB
    static hasMany = [domainBs : DomainB]
}

class DomainA implements GormEntity<DomainA> {

static belongsTo = DomainB

static hasMany = [domainBs : DomainB]

}

と


class DomainB implements GormEntity<Child> {
    static hasMany = [domainAs : DomainA]

class DomainB implements GormEntity<Child> {

static hasMany = [domainAs : DomainA]

の二つがあって、Many to Many の関係にある。
この時、保存は以下の順序で行う。

DomainAのList(domainAList) と、DomainB(domainB)がある場合、
DomainB に、DomainA を全て入れてから、DomainBを保存する


for(DomainA domainA : domainAList) {
    domainB.addToDomainAs(domainA)
}
domainB.save(flush:true)

for(DomainA domainA : domainAList) {

domainB.addToDomainAs(domainA)

}

domainB.save(flush:true)

更新は、DomainAのListと、DomainBがある場合
DomainAのListのコピーを作成しておき、(domainAListCopy) 、以下のように行う


domainAListCopy.each {
    it.removeDomainBs(domainB)
    it.save()
}
domainB.domainAs.clear()

for(DomainA domainA : domainAlist) {
    domainA.addToDomainBs(domainB)
    domainA.save(flush:true)
}

domainB.save(flush:true)

domainAListCopy.each {

it.removeDomainBs(domainB)

it.save()

}

domainB.domainAs.clear()

for(DomainA domainA : domainAlist) {

domainA.addToDomainBs(domainB)

domainA.save(flush:true)

}

domainB.save(flush:true)
