Oracle + dbunit获取AmbiguousTableNameException

Question

我使用dbunit创建数据库备份,可以导入和导出.我的应用程序可以使用几个数据库引擎:MySQL,PostgreSQL,SQLServer,H2和Oracle.

所有上述工作都可以使用以下代码:

            // Connect to the database 
        conn =BackupManager.getInstance().getConnection();
        IDatabaseConnection connection = new DatabaseConnection(conn);
        InputSource xmlSource = new InputSource(new FileInputStream(new File(nameXML)));
        FlatXmlProducer flatXmlProducer = new FlatXmlProducer(xmlSource);
        flatXmlProducer.setColumnSensing(true);

        DatabaseOperation.CLEAN_INSERT.execute(connection,new FlatXmlDataSet(flatXmlProducer));  

但在Oracle上我得到了这个例外:

!ENTRY es.giro.girlabel.backup 1 0 2012-04-11 11:51:40.542
!MESSAGE Start import backup
org.dbunit.database.AmbiguousTableNameException: AQ$_SCHEDULES

Answer 1

来自文档:

public class AmbiguousTableNameException extends DataSetException

IDataSet当可以访问具有相同名称的多个表时,抛出此异常.当数据库连接可以访问包含相同表名的多个模式时,通常会发生这种情况.

可能的解决方案:

1)使用只能访问一个数据库模式的数据库连接凭据.

2)指定架构名称的 DatabaseConnection或DatabaseDataSourceConnection构造.

3)启用限定表名称支持(请参阅操作方法文档).

为谁使用SpringDBUnit。我一直在为这个非常烦人的问题而苦苦挣扎。我已经结束了通过增加配置解决问题com.github.springtestdbunit.bean.DatabaseConfigBean和com.github.springtestdbunit.bean.DatabaseDataSourceConnectionFactoryBean。

这是我对SpringDBUnit的完整Spring上下文
