Grails丢弃域对象

Question

void businessMethod(def object) {
    // invoke discard only on hibernate objects
    if (isDomainObject(object))
        object.discard()
    // other stuff
}

我如何验证对象是否是grails域对象并由hibernate管理？

Answer 1

你可以尝试

grailsApplication.domainClasses*.clazz.contains(Hibernate.getClass(object))

见：http://grails.1312388.n4.nabble.com/Check-if-object-is-a-domain-instance-td3224172.html

Answer 2

    if (object.metaClass.respondsTo(object, "discard")) {
        object.discard()
    }
