Grails可搜索插件 - 沒有被列入索引的實體

Question

我在Grails 2.2.3應用程序中使用Searchable Plugin 0.6.4，但遇到了一個奇怪的錯誤。錯誤說：GrailsContextLoader Error initializing the application: No entities listed to be indexed, have you defined your entities correctly?

我只有一個類列出索引。下面是這個類（簡化了一下）：

class Incident { 

    String howReceived 
    Date timeOfCall 
    Date timeOfArrival 

    User reportingOfficer 

    static searchable = [ except: ['version', 'dateCreated', 'lastUpdated'] ] 

    static embedded = [ 'witnesses' ] 
    static hasMany = [ witnesses: Witness ] 

    static mapping = { 
     datasource 'police' 
     table 'incidents' 
    } 
} 

這就是我所擁有的一個簡單的映射。下面我還包括了我打開的堆棧跟蹤和調試語句。

編輯：看來，由於某種原因，sessionFactory豆未在DefaultHibernateEntitiesLocator類找到任何類的元數據。所以...

Map allClassMetaData = sessionFactory.getAllClassMetadata(); 
assert allClassMetaData == null 

不確定爲什麼或者如果這些信息有幫助。

的問題是使用一個數據源使用非默認名稱，在這種情況下， '警察'。我沒有看到文檔中的任何地方提到插件不會使用與「dataSource」不同的名稱的數據源。我會盡快更新他們的文檔。

我發現修復here。如果鏈接出現故障，請執行以下操作。以下內容添加到resources.groovy：

import org.compass.gps.device.hibernate.HibernateGpsDevice 
import grails.plugin.searchable.internal.compass.config.SessionFactoryLookup 

beans = { 
    compassGpsDevice(HibernateGpsDevice) { bean -> 
     bean.destroyMethod = "stop" 
     name = "hibernate" 
     sessionFactory = { SessionFactoryLookup sfl -> 
      sessionFactory = ref('sessionFactory_datasourceName') 
     } 
     fetchCount = 5000 
    } 
} 

要添加其他數據源與可轉位類，添加以下內容：

anotherUniquecompassGpsDevice(HibernateGpsDevice) { bean -> 
    bean.destroyMethod = "stop" 
    name = "unqiueHibernateName" 
    sessionFactory = { SessionFactoryLookup sfl -> 
     sessionFactory = ref('sessionFactory_uniquedatasource') 
    } 
    fetchCount = 5000 
    } 

最後加......你可能想

import org.compass.gps.impl.SingleCompassGps 

compassGps(SingleCompassGps) { 
    compass = ref('compass') 
    gpsDevices = [compassGpsDevice, anotherUniqueCompassGpsDevice] 
}
