從Grails 2.2.4遷移到2.4.3後,在條件查詢中使用該屬性時,具有名爲applicationContext的屬性的域類會引發異常。'applicationContext'在Grails 2.4.3中被禁止作爲域屬性名嗎?

class WebResource { 
    String applicationContext 
} 

class ResourceService { 
    public WebResource getResourceByContext(String ctx) { 
    WebResource.withCriteria() { 
     eq('applicationContext', ctx) 
    } 
    } 
} 

到getResourceByContext(A調用)拋出一個異常:

用 '的applicationContext' 不允許的Grails 2.4.3名稱

是具有域屬性?我無法在Grails發行說明,升級指南或JIRA中找到對此方案的引用。我已經通過重命名字段,GORM改變引用新名稱解決此問題的工作:

class WebResource { 
    String appContext 
    appContext column: 'APPLICATION_CONTEXT' 
    public String getApplicationContext() { 
     return appContext 
    } 

    public void setApplicationContext(String c) { 
     appContext = c 
    } 
}

考慮到與Spring的ApplicationContext名稱衝突我懷疑你已經找到了最好的答案已經 - 屬性命名爲別的東西並使用mapping定義來設置數據庫列名稱。我建議你不要添加getter/setter對,但直接在你的代碼中使用屬性名稱appContext,因爲Grails核心或插件中有很多可能的地方(我認爲相當合理)假設名爲applicationContext的屬性是Spring對象而不是其他任何東西。

除非必須,否則不要反對約定。
