在Grails和MongoDB中有一个非常奇怪的问题,在我的生产环境中,我遇到以下错误。

当我尝试将新的跟踪对象插入数据库时,就会发生这种情况:
Tracking tp = new Tracking()
tp.setUser(user)
nowCal.add(Calendar.MINUTE,i++)
tp.setCreated(nowCal.getTime())
tp.setSpeed(10f)
tp.setLocation(new Point(points[1],points[0]))
tp.save(flush:true)
user.addToTracking(tp);
我的Tracking类的定义如下:
import grails.mongodb.geo.Point
class Tracking {
Point location
Date created
float speed
static belongsTo = [user:User]
static constraints = {
speed nullable:true
}
static mapping = {
location geoIndex:'2dsphere'
}
}
我真的看不到问题出在哪里,我想我已经按照GORM文档中的说明正确定义了所有内容:http://gorm.grails.org/latest/mongodb/manual/#geoSpatial
另一件事是,此代码在非生产模式下运行时效果很好。
因此执行grails run-app
可以,但是grails prod run-app
不能。.
任何帮助将不胜感激。
谢谢
李。
答案 0 :(得分:1)
我遇到了同样的问题,经过两天的调试终于找到了解决方法。
org.grails.datastore.mapping.reflect.FieldEntityAccess
的Grails实用程序类,显然用于通过反射访问实体字段。该类具有称为FieldEntityReflector
的内部类。每次创建FieldEntityAccess
实例时,都会在内部创建一个FieldEntityReflector
实例。所有这些实例都存储在名为REFLECTORS
的静态映射中,其键是实体名称,这显然是出于性能原因。mongoDatastore
bean为每个实体创建一个FieldEntityAccess
,并传递一个DocumentPersistentEntity
作为构造函数参数。grailsDomainClassMappingContext
Bean,不知道mongoDatastore
,会为每个实体创建自己的FieldEntityAccess
,并向下传递KeyValuePersistentEntity
作为参数。那些FieldEntityAccess
实例及其对应的EntityReflectors
不知道mongo,因此不支持像Point
这样的mongo特定类型。REFLECTORS
映射键是实体名称,EntityReflectors
最后为同一实体创建,覆盖了先前创建的反射器,并被所有EntityReflector
实例使用。grailsDomainClassMappingContext
个反射器时,当mongo尝试持久化和实体化并因此引发错误时,将使用它们。grailsDomainClassMappingContext
bean之后初始化mongoDatastore
bean时引发错误。在开发模式下,UrlMappingsGrailsPlugin
插件创建了一些用于重新加载url映射的bean。这些bean触发grailsDomainClassMappingContext
bean之前的mongoDatastore
bean实例化。在以后创建mongo bean时,不会引发错误。但是,在生产模式下,不会创建这些bean,而是在mongoDatastore
之前创建grailsDomainClassMappingContext
,从而引发错误。
grailsDomainClassMappingContext
之前强制执行mongoDatastore
bean实例化:几次尝试后,我都无法执行此操作,可能是因为grails bean实例化逻辑。UrlMappingsGrailsPlugin
实例化:由于可能会对性能产生影响,我不希望这样做。clearReflectors
类的静态方法FieldEntityAccess
清除系统初始化后的所有反射器:**我决定这样做,系统开始工作。我尚未对其进行深入测试,但能够正确持久Point
。为了调用该方法,我根据grailsDomainClassMappingContext
和mongoDatastore
创建了一个bean,并命名为FieldEntityAccess.clearReflectors()
package app.utils
import org.grails.datastore.mapping.mongo.MongoDatastore
import org.grails.datastore.mapping.reflect.FieldEntityAccess
import org.grails.datastore.mapping.model.MappingContext
class MongoDatastoreHolder {
MongoDatastore mongo
MappingContext context
MongoDatastoreHolder(MappingContext context, MongoDatastore mongo) {
this.context = context
this.mongo = mongo
FieldEntityAccess.clearReflectors()
}
}
并在resources.groovy
中定义该bean:
import app.utils.MongoDatastoreHolder
beans = {
mongoDatastoreHolder(MongoDatastoreHolder, ref('grailsDomainClassMappingContext'), ref('mongoDatastore')) { bean ->
bean.lazyInit = false
}
}
希望这会有所帮助,对于我的英语不好,这是我第一个StackOverflow答案。
