hibernate - Grails自定义 validator 错误

Question

我使用Grails 2.3.7。
我的域类产品:

class Product {
    static belongsTo = [firmData: Firm_data]

    String name
    SectorType sectorType
    Measure measure
    Float soldProducts
    Float percentOfIncome
    Float percentOfExpense

    static constraints = {
        name blank:false, unique: 'firmData'
        percentOfIncome (range: 0..100, validator: {value, object ->
            def products = Product.findAllByFirmData(object.firmData)
            def sumOfIncome = (products?.percentOfIncome?.sum() ?: 0) + object.percentOfIncome
            print sumOfIncome
            return (sumOfIncome <= 100)
        })
        percentOfExpense (range: 0..100, validator: {value, object ->
            def products = Product.findAllByFirmData(object.firmData)
            def sumOfExpense = (products?.percentOfExpense?.sum() ?: 0) + object.percentOfExpense
            print sumOfExpense
            return (sumOfExpense <= 100)
        })
    }
}

我要确保下一个添加的 Product(它也属于指定的 Firm_data firmData)不会在值 percentOfIncome或 percentOfExpense上超过值100(当为选定的Firm_data汇总产品的所有实例时)。

在执行Bootstrap时尝试添加初始数据时出现错误:

它在 def products = Product.findAllByFirmData(object.firmData)行崩溃。

如何解决？为什么会发生？

Answer 1

我不知道验证器如此频繁地执行。解决方案:
import org.hibernate.FlushMode
并且比在自定义验证器中从数据库检索数据时更改FlushMode的方式(以避免不必要的刷新更改):

percentOfIncome (range: 0..100, validator: {value, object ->
    def products = Product.findAllByFirmData(object.firmData, [flushMode: FlushMode.MANUAL] )
    def sumOfIncome = (products?.percentOfIncome?.sum() ?: 0) + object.percentOfIncome
    return (sumOfIncome <= 100)
        })
