Grails - 休眠表不會自動生成

我在應用程序中集成了spring security core插件。用s2-quickstart com.myApplication.secureapp SecAppUser SecAppRole創建後。我已經在我的域圖層中獲得了另外兩個類SecAppRole.groovy和SecAppUser.groovy。我也加入到我的BootStrap.groovy：Grails - 休眠表不會自動生成

class BootStrap { 

    def init = { servletContext -> 
    def adminRole = new SecAppRole(authority: 'ROLE_ADMIN').save(flush: true) 
    def userRole = new SecAppRole(authority: 'ROLE_USER').save(flush: true) 

    def testUser = new SecAppUser(username: 'admin', enabled: true, password: 'admin') 
    testUser.save(flush: true) 

    SecAppUserSecAppRole.create testUser, adminRole, true 

    assert SecAppUser.count() == 1 
    assert SecAppRole.count() == 2 
    assert SecAppUserSecAppRole.count() == 1 
    } 

    def destroy = { 
    } 
}

例如SecAppRole.groovy看起來像這樣：

class SecAppRole { 

    String authority 

    static mapping = { 
     cache true 
    } 

    static constraints = { 
     authority blank: false, unique: true 
    } 
}

然而，添加代碼到Bootstrap.groovy文件後，我得到：

我可以清楚地看到我的postgresql數據庫中沒有創建的表。然而，我試過的：

我創建了hibernate文件 grails create-hibernate-cfg-xml。但是這不會改變我的輸出。

我的問題很明顯是在運行應用程序後表格沒有被創建。如何指定表格由grails 2自動生成，例如hibernate？

我很感謝您的回答！

UPDATE

這裏是我的DataSource.groovy：

dataSource { 
    pooled = true 
    driverClassName = "org.postgresql.Driver" 
    dialect = org.hibernate.dialect.PostgreSQLDialect 
    username = "testApplicationUser" 
    password = "admin" 
} 
hibernate { 
    cache.use_second_level_cache = true 
    cache.use_query_cache = false 
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3 
    // cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4 
} 

// environment specific settings 
environments { 
    development { 
     dataSource { 
      dbCreate = "" 
      driverClassName = "org.postgresql.Driver" 
      dialect = "net.kaleidos.hibernate.PostgresqlExtensionsDialect" 
      url = "jdbc:postgresql://localhost:5432/testApplication" 
      username = "testApplicationUser" 
      password = "admin" 
     } 
    } 
    test { 
     dataSource { 
      dbCreate = "" 
      driverClassName = "org.postgresql.Driver" 
      dialect = "net.kaleidos.hibernate.PostgresqlExtensionsDialect" 
      url = "jdbc:postgresql://localhost:5432/testApplication" 
      username = "testApplicationUser" 
      password = "admin" } 
    } 
    production { 
     dataSource { 
      dbCreate = "update" 
      url = "jdbc:h2:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE" 
      properties { 
       maxActive = -1 
       minEvictableIdleTimeMillis=1800000 
       timeBetweenEvictionRunsMillis=1800000 
       numTestsPerEvictionRun=3 
       testOnBorrow=true 
       testWhileIdle=true 
       testOnReturn=false 
       validationQuery="SELECT 1" 
       jdbcInterceptors="ConnectionState" 
      } 
     } 
    } 
}

我會建議看dbCreate的在你的grails-app/conf目錄/ DataSource.groovy中的價值，並確保它被設置爲「創建「或」更新「。有關在Grails中配置數據源的更多信息，請參閱documentation。

非常感謝您的回答！請參閱我的更新;） – mrquad

非常歡迎。你可以看到你的dbCreate在開發和測試中都是空白的。（： –

非常感謝您的回答！它現在可以工作;） – mrquad
