Question

我们正在使用Grails 2.3.11和joda-time插件1.4。

我试图使用像这样的where查询：

Form.where { year(dateCreated) == currYear }.list()

在此currYear是一个整数，dateCreated的类型为org.joda.time.DateTime

结果就是这个例外：

org.springframework.dao.InvalidDataAccessResourceUsageException: Unsupported function [year] defined in query for property [datum] with type [class org.joda.time.DateTime]
    at org.grails.datastore.gorm.finders.DynamicFinder.applyDetachedCriteria(DynamicFinder.java:440)
    at grails.gorm.DetachedCriteria.withPopulatedQuery_closure10(DetachedCriteria.groovy:1201)
    at org.grails.datastore.gorm.GormStaticApi.withDatastoreSession_closure23(GormStaticApi.groovy:699)
    at org.grails.datastore.mapping.core.DatastoreUtils.execute(DatastoreUtils.java:302)
    at org.grails.datastore.gorm.AbstractDatastoreApi.execute(AbstractDatastoreApi.groovy:37)
    at org.grails.datastore.gorm.GormStaticApi.withDatastoreSession(GormStaticApi.groovy:698)
    at grails.gorm.DetachedCriteria.withPopulatedQuery(DetachedCriteria.groovy:1185)
    at grails.gorm.DetachedCriteria.list(DetachedCriteria.groovy:845)
    at grails.gorm.DetachedCriteria.list(DetachedCriteria.groovy:844)

使用joda-time时似乎不支持像year（）这样的函数。它是否正确？或者我做错了什么？

在joda-time插件中添加对此的支持有多难？或者在其他地方？

Grails where-query使用joda-time
