Groovy在调用getter方法时抛出MissingPropertyException

我正在为Hybris编写一个小的Groovy脚本

由于未知原因，当我尝试调用.getCronExpression（）时，Groovy尝试获取名为getCron的属性

Script execution has failed [reason: groovy.lang.MissingPropertyException: No such property: getCron for class: de.hybris.platform.cronjob.model.TriggerModel]

我试图调用的getter存在于类中

def methods = TriggerModel.declaredMethods.findAll { !it.synthetic }.name
println methods;
//[getDaysOfWeek, getWeekInterval, setDaysOfWeek, setWeekInterval, getRelative, getJob, setActivationTime, setMaxAcceptableDelay, getTimeTable, setActive, setJob, getCronJob, getActivationTime, setDateRange, getDateRange, getMaxAcceptableDelay, getCronExpression, setCronExpression, setCronJob, getActive, setRelative, setDay, setHour, setMinute, setSecond, getHour, getMinute, getSecond, getYear, getMonth, setYear, setMonth, getDay]

代码部分：

def currentDate = new Date();
def query = new FlexibleSearchQuery("SELECT {pk} FROM {cronjob} WHERE {active} IS true");
def result = flexibleSearchService.search(query).getResult();
for (cj in result) {
  def activeTriggers = cj.getTriggers().stream().filter{p -> p.getActive()}.collect();

  if (activeTriggers){
    def at = activeTriggers.get(0);
    def activationTS = at.getActivationTime(); // works
    if (activationTS.before(currentDate)){
      println cj.code + " has invalid next activation date set: " + activationTS; 
    }

    def x = at.getCronExpression(); // error
  }

更新：该项目使用hybris 5.7

您可以在加载

activeTriggers

的地方共享您的groovy部件吗

我创建了一个示例groovy来加载触发器，并为第一个对象打印

CronExpression

，它的工作非常出色

import de.hybris.platform.servicelayer.search.FlexibleSearchQuery;

flexibleQuery = new FlexibleSearchQuery("select {pk} from {Trigger}");
flexibleSearchService = spring.getBean("flexibleSearchService")
activeTriggers = flexibleSearchService.search(flexibleQuery).getResult();

def at = activeTriggers.get(0);
def x = at.getCronExpression(); 

输出

0 0 0/4 * * ? *

在PO编辑问题后我仍然没有看到

getCronExpression

错误，我相信您当时是在另一个对象上调用函数的

TriggerModel

。尽管groovy中存在一些语法错误，但副本的工作版本如下所示。（1905年版测试）

用变量名替换getter修复了这个问题

替换-

def x = at.getCronExpression(); // error

与

完全工作槽-

import de.hybris.platform.servicelayer.search.FlexibleSearchQuery;

def currentDate = new Date();
def query = new FlexibleSearchQuery("SELECT {pk} FROM {cronjob} WHERE {active}='1'");
def result = flexibleSearchService.search(query).getResult();
for (cj in result) {
  def activeTriggers = cj.getTriggers().stream().filter{p -> p.getActive()}.collect();

  if (activeTriggers){
    def at = activeTriggers.get(0);
    def activationTS = at.getActivationTime(); // works
    if (activationTS.before(currentDate)){
      println cj.code + " has invalid next activation date set: " + activationTS; 
    }

    def xam = at.cronExpression; // working
  }
}

更新了问题。您现在遇到了什么错误？看来你一定没有遇到你之前遇到的问题，也就是说，没有found@www.hybriscx.com您使用的是哪个版本的hybris？事实上，我尝试了我们的代码，但出现了相同的错误，但似乎

at.\u cronExpression

是一种变通方法（groovy似乎跳过了“表达式”这个词），这怎么可能呢？表达式在Groovy中不是保留关键字。它可能与我们正在使用的hybris版本（5.7）有关。我想是的，这似乎是在hybris的最新版本上修复的。是的，这解决了它。但是没有回答为什么Groovy不能正确地调用getter。

def xam = at.cronExpression; // working

import de.hybris.platform.servicelayer.search.FlexibleSearchQuery;

def currentDate = new Date();
def query = new FlexibleSearchQuery("SELECT {pk} FROM {cronjob} WHERE {active}='1'");
def result = flexibleSearchService.search(query).getResult();
for (cj in result) {
  def activeTriggers = cj.getTriggers().stream().filter{p -> p.getActive()}.collect();

  if (activeTriggers){
    def at = activeTriggers.get(0);
    def activationTS = at.getActivationTime(); // works
    if (activationTS.before(currentDate)){
      println cj.code + " has invalid next activation date set: " + activationTS; 
    }

    def xam = at.cronExpression; // working
  }
}
