ClassNotFoundException：grails.validation.ConstraintFactory

Question

我在独立模式下使用 GORM-mongodb：

compile 'org.grails:grails-datastore-gorm-mongodb:6.0.4.RELEASE'

我的域名类如：

@Entity
class Module {

  String id

  String tags

  Ability ability

  Map<String,String> metrics

  static constraints = {
    metrics nullable:true
  }

  static mapping = {
    version false
  }
}

我正在像这样初始化数据源：

new MongoDatastore( config, Ability, Module )

在 init-phaze 结束时，我总是看到错误：

这是一个错误还是我做错了什么？

Answer 1

事实证明，必须添加另一个 grails 依赖项，例如

compile 'org.grails:grails-validation:3.1.14'

然后编译正常运行

ClassNotFoundException：grails.validation.ConstraintFactory

ClassNotFoundException: grails.validation.ConstraintFactory

validation

grails-orm

mongodb
