grails 中的 NullPointerException 错误
NullPointerException error in grails
我真的很生气。
我的目标是保存其中state/region一个对象，所以我设置了这个域class：
class State {
String stateName
String stateIsoCode
static hasMany = [regions: Region]
static constraints = {
stateIsoCode unique:true
stateName unique:true
}
}
class Region {
String regionName
String regionIsoCode
static belongsTo = [state: State]
static hasMany = [provinces: Province]
static constraints = {
regionIsoCode unique:true
regionName unique:true
}
}
当有人想插入他的对象的位置时，他可以使用 select 来完成，该 select 的值是州或地区的 isoCode
所以在控制器中我尝试这样设置对象的位置：
materialInstance.state = State.findByStateIsoCode(params?.state)
materialInstance.region = Region.findByRegionIsoCodeAndState(params.region,materialInstance.state)
我收到这个错误：

我不明白是什么原因造成的，此外，如果我评论保存状态和区域的代码片段，我会通过控制器（我得到错误，因为它们不是可为空的字段）然后我取消注释，它有效。
我正在使用带有 nosql 数据库的 grails，并且正在调试环境
谢谢
由底层 Hibernate 问题引起 https://hibernate.atlassian.net/browse/HHH-11721
我真的很生气。
我的目标是保存其中state/region一个对象，所以我设置了这个域class：
class State {
String stateName
String stateIsoCode
static hasMany = [regions: Region]
static constraints = {
stateIsoCode unique:true
stateName unique:true
}
}
class Region {
String regionName
String regionIsoCode
static belongsTo = [state: State]
static hasMany = [provinces: Province]
static constraints = {
regionIsoCode unique:true
regionName unique:true
}
}
当有人想插入他的对象的位置时，他可以使用 select 来完成，该 select 的值是州或地区的 isoCode
所以在控制器中我尝试这样设置对象的位置：
materialInstance.state = State.findByStateIsoCode(params?.state)
materialInstance.region = Region.findByRegionIsoCodeAndState(params.region,materialInstance.state)
我收到这个错误：
