Grails抛出表"xxx"未找到

Question

在Grails中,我可以在BootStrap中的内存dataSource中创建域对象,并将结果恢复正常,但是一旦应用程序启动(例如从GSP或控制器查询),我尝试运行查询,我得到:

org.h2.jdbc.JdbcSQLException: Table "FUNCTIONAL_DOC_TYPE" not found; SQL statement:
select this_.id as id1_0_, this_.version as version1_0_, this_.direction_id as direction3_1_0_, this_.functional_group_id as functional4_1_0_, this_.type_name as type5_1_0_ from functional_doc_type this_ [42102-147]

• 我已经清理了构建

• 运行Grails 2.0.0

• 我有多个数据源到SQL服务器DB,它们只调用StoredProcedures,现在发现一个用例,使用好的旧Domain对象在内存存储中使用H2 ......错误只发生在
  域上.

• 我运行dbconsole,找到的唯一表是标准的28
  "内部"表...没有来自我的应用程序

一些来源:

DataSource.groovy的

// "Parent" datasource def

dataSource_messages {
    pooled = true
    driverClassName = "net.sourceforge.jtds.jdbc.Driver"
    username = "user"
    password = "secret"
    readOnly = "true"
}


// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:h2:mem:app_data;MVCC=TRUE"
            pooled = true
            driverClassName = "org.h2.Driver"
            username = "sa"
            password = ""
            readOnly = false
        }
        dataSource_messages {
            url = "jdbc:jtds:sqlserver://localhost:1433;DatabaseName=Messages"
        }

域类:

class FunctionalDocType {
    String typeName
    FunctionalGroup functionalGroup
    DocDirection direction

    static constraints = {
        functionalGroup(nullable: true)
    }

}

BootStrap.groovy中:

   new FunctionalDocType(typeName: 'Order',   direction: buyerToSeller, functionalGroup: orders).save().save(flush: true)

   //  insert into functional_doc_type (id, version, direction_id, functional_group_id, type_name) values (null, ?, ?, ?, ?)


   FunctionalDocType.findAll() runs:

    // DEBUG SQL - select this_.id as id1_0_, this_.version as version1_0_, this_.direction_id as direction3_1_0_, this_.functional_group_id as functional4_1_0_, this_.type_name as     type5_1_0_ from functional_doc_type this_

并返回所有正确的值.

所以它就像内存中的tabes在某个地方引导后被删除但是没有被记录.

任何帮助赞赏.

谢谢,

Answer 1

H2在最后一个连接关闭时关闭数据库.对于内存数据库,关闭连接意味着数据丢失...

所以,如果你一直打开一个连接,那么你应该没问题.你可以称之为"哨兵"连接.

另一个选择是使用持久数据库(数据库URL jdbc:h2:~/test/app_data;MVCC=TRUE)
