grails - 自定义错误消息无法在带有grails的gorm中使用

Question

似乎无法在Grails 2.3.7上获得自定义验证消息。

class Team {
   int id
   String email

   static mapping = {
     id     column:'TEAM_ID', generator:'native'
     email  column:'TEAM_EMAIL' 
   }
   static constraints = { 
     email  unique:true
   }

messages.properties (尝试了所有这些...)

team.email.unique=Email already used!
Team.email.unique=Email already used!
my.package.Team.email.unique=Email already used!

验证问题由我的服务处理，但是自定义错误消息从未使用:

Team t = new Team(...)
if(!t.validate())
   println t.errors

输出...

Field error in object 'Team' on field 'email': rejected value.... ...
default message [Property [{0}] of class [{1}] with value [{2}] must be unique]

不知道是什么问题，根据 docs，约定是:
[Class Name].[Property Name].[Constraint Code]
额外配置

BuildConfig

dependencies {
    compile('com.oracle:ojdbc6:11.2.0')
}
plugins {
    build ":tomcat:7.0.52.1"
    runtime ":hibernate:3.6.10.9"
}

数据源

 dialect  =  "org.hibernate.dialect.Oracle10gDialect"
 hibernate {
    cache.use_second_level_cache = false
    cache.use_query_cache = false
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
    singleSession = false 
}

根据http://grails.org/doc/2.3.7/ref/Constraints/unique.html上的唯一约束文档页面，它是className.propertyName.unique，但是println t.errors始终看起来像您所看到的-toString()结果不是很有用。要查看已解决/已翻译的消息，您可以测试您在测试或测试应用中的工作，并可以使用它来显示已解决的消息:

// dependency injection in controller/service/etc.
def messageSource

...

Locale locale = Locale.getDefault()
def stringsByField = [:].withDefault { [] }

for (fieldErrors in t.errors) {
   for (error in fieldErrors.allErrors) {
      String message = messageSource.getMessage(error, locale)
      stringsByField[error.field] << message
   }
}

println stringsByField
