【中文标题】Grails hibernate/Searchable 通过给出以下异常来停止服务器启动

【英文标题】：Grails hibernate/Searchable stops server to start by giving the exception below

【发布时间】：2013-03-04 09:02:33

【问题描述】：

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出现下面的 drows 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

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

我们已尝试删除可搜索索引并重新启动，但它也无法启动。

只有当我们截断以上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，但没有成功。 请帮助我们解决这个问题。

【问题讨论】：

您是否尝试过删除现有的索引文件？

是，但根本没用

@Shashank.gupta40，祝你好运，我也面临这个问题。你能帮帮我吗？

您找到解决方案了吗？我们现在遇到了同样的问题。

@whitenexx : 尝试使用以下链接在启动时配置批量索引grails.org/Searchable+Plugin+-+FAQ。

【参考方案1】：

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()
   

【讨论】：

但是它不会索引数据库，如果我们必须索引数据库怎么办？

我已按照您的步骤操作，但仍然存在错误。 2013 年 9 月 13 日 14:36:17:225 错误 hibernate：无法索引数据库 org.compass.core.engine.SearchEngineException：处理器 [2]：无法添加作业 [作业创建 [别名 [成员] uid [成员#586#]] 资源 [Member ..... 在 [10000ms] 和积压大小 [100] 之后有什么想法吗？
