grails - 服务验证域模型

我从服务的域验证中遇到消息方法问题。有谁知道如何解决这个问题？以下是服务方法。当我的 Controller 正在调用时:glossaryService.post(params, 'save')。

@Transactional
class GlossaryService {

//  Saving glossary
def post( def params,def currentURI ) {
    params.status = params.status ? Status.PUBLISHED.value() : Status.DRAFT.value()

    def result = [success: false, message: ""]
    def glossary = null

    if (params.action == 'save') {
        glossary = new Glossary(params)
    } else if (params.action == 'update') {
        glossary = Glossary.get(params.id)
        glossary.name = params?.name
        glossary.description = params?.description
        glossary.glossaryTerm = params?.glossaryTerm
        glossary.status = params?.status
    }

    if (glossary.validate()) {
        result = glossary.save(flush: true, failOnError: true)
    }

    if (glossary.hasErrors()) {
        transactionStatus.setRollbackOnly()

        result.errors = glossary.errors
        def errors = glossary.errors.allErrors.collect {
            message(error: it)
        }

        respond glossary.errors, view: '/admin/glossary/'+currentURI, model: [
                glossary: params
        ]
        return
    }

    return result
}
}

它提示的错误是:

最佳答案

注入(inject)messageSourceMessageSource messageSource
然后用
messageSource.getMessage(...)
