hibernate - Grails 2.1:如何使用 “schema-export export”？

Question

我想使用命令“schema-export”(重新)创建数据库模式。 DDL生成工作正常，但是如果执行“模式导出导出”，则会收到以下错误，这表明配置文件中缺少某些内容。

grails> dev schema-export export
| Compiling 1 source files.....
Exporting in environment 'development' for the default DataSource
| Error 2012-08-24 14:45:57,466 [main] ERROR hbm2ddl.SchemaExport  - schema export unsuccessful
Message: No local DataSource found for configuration - 'dataSource' property must be set on LocalSessionFactoryBean
  Line | Method
->> 61 | doCall in SchemaExport$_run_closure1

我的DataSource.groovy定义了一个“数据源”:

dataSource {
    pooled = true
    driverClassName = "com.mysql.jdbc.Driver"
}
...
environments {
    development {
        dataSource {
            username = "xxx"
            password = "yyy"
            url = "jdbc:mysql://localhost:3306/chrono_dev?autoreconnect=true"
        }
    }
    ...
}

任何建议如何解决此错误？

Answer 1

语法有点不同:

grails dev schema-export // no export

根据这个:

http://grails.org/doc/2.1.0/ref/Command%20Line/schema-export.html

如果要进行导入，则可能需要描述数据源:

grails dev schema-export export --datasource=auditing

另外，您要导入的DDL的名称是什么？
