hibernate - Grails- hibernate 不会自动生成表

Question

我已经将spring security core插件集成到了我的应用程序中。用s2-quickstart com.myApplication.secureapp SecAppUser SecAppRole创建之后。我在我的域层中又获得了2个类SecAppRole.groovy和SecAppUser.groovy。我还添加了我的BootStrap.groovy:

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看起来像这样:

class SecAppRole {

    String authority

    static mapping = {
        cache true
    }

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

但是，将代码添加到 Bootstrap.groovy文件后，我得到:

我可以在我的postgresql数据库中清楚地看到未创建表的地方。但是，我尝试了什么:

我使用
grails create-hibernate-cfg-xml创建了休眠文件。但是，这不会改变我的输出。

我的问题很明显是在运行应用程序后无法创建表。如何指定表由 grails 2自动生成，例如使用 hibernate？

感谢您的回答!

这是我的 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"
            }
        }
    }
}

我建议您在grails-app / conf / Datasource.groovy中查看dbCreate的值，并确保将其设置为“create”或“update”。可以在documentation中找到有关在Grails中配置数据源的更多信息。
