hibernate - 需要帮助通过今天的日期查询数据库，而忽略时间

Question

我有一个grails项目，该项目使用hibernate与postgres数据库进行通信。我正在使用joda时间插件。我一直在使用他们的DateTime格式2013-01-25 22:28:55来存储日期。我需要知道两个星期前什么时候发生了什么事，变量deadline出现了。

import org.joda.time.DateTime

Collection<PerformanceReview> outstandingSelfEvaluations(DateTime deadline) {
    Person.executeQuery("select pr from PerformanceReview as pr \
                    inner join pr.performanceReviewStatus as status \
                    where status.name in (:name) \
                    and pr.employeeEvaluation = null \
                    and pr.dateCreated = :deadline",
            [name: ['Open', 'New'], deadline: deadline])
}

主功能

def incompleteSelfEvaluations(Integer days) {
    def deadline = LocalDate.now().minusDays(days)
    def performanceEvaluations = outstandingSelfEvaluations(deadline)

    performanceEvaluations.each { PerformanceReview pr ->
        sendSelfEvaluationReminderEmail(pr, evaluationDeadline)
    }
}

唯一的问题是，我不知道如何忽略时间只检查日期。

编辑:添加了所有相关代码，并删除了对于此特定问题无用的错误消息

看起来似乎有些杂音，但是使用Hibernate的DAY，MONTH和YEAR功能效果很好。您可以在documentation中找到有关这些功能的更多信息。这样，您不必担心会传递其他信息，而且它与数据库无关。

Collection<PerformanceReview> outstandingSelfEvaluations(LocalDate deadline) {
    Person.executeQuery("select pr from PerformanceReview as pr \
                    inner join pr.performanceReviewStatus as status \
                    where status.name in (:name) \
                    and pr.employeeEvaluation = null \
                    and DAY(pr.dateCreated) = DAY(:deadline)
                    and MONTH(pr.dateCreated) = MONTH(:deadline)
                    and YEAR(pr.dateCreated) = YEAR(:deadline)",
            [name: ['Open', 'New'], deadline: deadline])
