grails - Grails可搜索插件-没有列出要索引的实体

Question

我在Grails 2.2.3应用程序中使用了Searchable Plugin 0.6.4，但是遇到一个奇怪的错误。错误提示:GrailsContextLoader Error initializing the application: No entities listed to be indexed, have you defined your entities correctly?
我只列出了要索引的一类。下面是该类(简化了一点):

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'
    }
}

这就是我所拥有的，一个简单的映射。下面，我还包括了我打开的堆栈跟踪和调试语句。

编辑:出于某种原因，看来sessionFactory bean在DefaultHibernateEntitiesLocator类中找不到任何类元数据。所以...

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

不知道为什么或该信息有帮助。

Answer 1

问题是使用具有非默认名称的数据源，在本例中为“police”。我在文档中没有任何地方提到该插件无法与名称不同于“dataSource”的数据源一起使用。我将尝试尽快更新其文档。

我找到了修复here。万一该链接断开，这就是您要做的。将以下内容添加到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
    }
}

要添加具有可索引类的其他数据源，请添加以下内容:

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

最后添加...

import org.compass.gps.impl.SingleCompassGps

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