Grails hibernate / Searchable通過在下面給出例外來阻止服務器啟動

Question

我們在Grails應用程序中使用Grails 2.1.1和Searchable插件0.6.4，並在某些域上實現搜索，下面顯示了所有映射。

class User {
      .....
      static hasMany = [userEducations : UserEducations , userWorkings : UserWorkings ]
      ......
      static searchable = {
        content: spellCheck 'include'
        all termVector: "yes"
        userEducations  component: true
        userWorkings component: true
      }
      ......
}

class UserEducations {
    .....
    Schools schools 
    .....
    static belongsTo = [user : User ]
    ......
    static searchable = {
        content: spellCheck 'include'
        all termVector: "yes"
        schools  component: true
    }
      ......
}

class UserWorkings {
      .....
      Organizations organizations 
      .....
     static belongsTo = [user : User ]
     ....
     static searchable = {
        content: spellCheck 'include'
        all termVector: "yes"
        organizations  component: true
     }
     ......
}

class Schools {
      ......
      static searchable = true
      ......
}

class Organizations {
      ......
       static searchable = true
      ......
}

使用正確的映射和約束可以成功保存數據。

問題開始時，我們在表用戶下面有drowslike關系

用戶a1 - > UserEducations b1 - >學校d1

和

用戶a2 - > UserEducations b2 - >學校d1

要么

用戶a1 - > UserWorkings c1 - >組織e1

和

用戶a2 - > UserWorkings c2 - >組織e1

（我們不確定上述事實可能是由於大量數據而發生的問題。）

然后當我們嘗試啟動服務器時，我們收到以下異常，服務器無法啟動

我們嘗試通過刪除可搜索的索引並再次重新啟動然后它也無法啟動。

僅當我們截斷與上述5個域相對應的表時，服務器才會啟動。

我們已盡力解決問題，但沒有運氣。 請幫我們解決這個問題。

轉到您的控制台並輸入：

grails install-searchable-config

然后打開myproject / grails-app / conf / Searchable.groovy並搜索以下內容並按照我的指示更改值。

mirrorChanges = false
bulkIndexOnStartup = false

在Bootstrap.groovy中：

class BootStrap {
   def searchableService

   def init = { servletContext ->
      // do any data loading you would normally do

      // Manually start the mirroring process to ensure that it comes after the automated migrations.
      println "Performing bulk index"
      searchableService.reindex()
      println "Starting mirror service"
      searchableService.startMirroring()
   }
}
