Hibernate Grails-在插入之前访问域中的ServiceClass方法时出现空id错误

在插入之前，我在我的域类中做了一些加密，效果很好。当我将代码移动到服务类时，尽管我得到了这个错误

MyDomainClass.groovy

SecurityService.groovy

你知道这是什么以及如何解决吗？如果重要的话，数据是通过BootStrap.groovy传入的，因为我还在测试

您是否在瞬态中定义了securityService？@injecteer-我没有，我的印象是，因为我使用的是'def'，所以不需要将其添加到瞬态列表中。不，您在这一点上错了：默认情况下，只有静态字段和最终字段被排除在持久化之外。因此，您必须在transientsThanks@injecteer中再次定义注入的服务-我根据文档尝试了静态瞬态=['securityService']，但仍然得到相同的错误。我的域类中有几乎相同的代码，它工作得很好。张贴你的stacktrace的其余部分

class MyDomainClass {
    …
    String password

    static constraints = {
        …
    }

    def securityService
    static transients = ['securityService']

    def beforeInsert() {    
        password = securityService.encryptData(password)
    }
}

class SecurityService {
    def encryptData(plainText) {
        …
        return encryptedData
    }
}
