我们在我们的 Grails 应用程序中使用 Grails 2.1.1 和 Searchable 插件 0.6.4，并在一些域上实现了可搜索，如下所示，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
      ......
}

使用正确的映射和约束成功保存数据。

当我们在具有关系的表用户中有下面的drowslike时，问题就开始了

用户 a1 -> UserEducations b1 -> 学校 d1

和

用户 a2 -> UserEducations b2 -> 学校 d1

或者

用户 a1 -> UserWorkings c1 -> 组织 e1

和

用户 a2 -> UserWorkings c2 -> 组织 e1

（我们不确定上述事实可能是由于大量数据而发生的问题。）

然后当我们尝试启动服务器时，我们收到以下异常并且服务器无法启动

我们尝试删除可搜索索引并重新启动，然后它也无法启动。

仅当我们截断与上述 5 个域对应的表时，服务器才会启动。

我们的问题类似于下面的帖子

http://grails.1312388.n4.nabble.com/hibernate-Searchable-failing-to-index-on-program-start-td4119566.html

我们已尽力解决问题，但没有运气。请帮助我们解决这个问题。

转到您的控制台并输入：

grails install-searchable-config

然后打开 myproject/grails-app/conf/Searchable.groovy 并搜索以下内容并更改我指出的值。

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()
   }
}
