java - DbUnit - 警告 : AbstractTableMetaData

Question

我在最新版本 2.4.8 中使用 DbUnit，我在我的单元测试中收到许多警告消息:

WARN : org.dbunit.dataset.AbstractTableMetaData - 
Potential problem found: The configured data type factory 
    'class org.dbunit.dataset.datatype.DefaultDataTypeFactory' 
     might cause problems with the current database 'MySQL' (e.g. some datatypes may 
     not be supported properly). In rare cases you might see this message because the 
     list of supported database products is incomplete (list=[derby]). If so please 
     request a java-class update via the forums.If you are using your own 
     IDataTypeFactory extending DefaultDataTypeFactory, ensure that you override 
     getValidDbProducts() to specify the supported database products.

所以我想我添加这个(我使用 MySQL 数据库):

protected void setUpDatabaseConfig(DatabaseConfig config) {
    config.setProperty(DatabaseConfig.PROPERTY_DATATYPE_FACTORY, new MySqlDataTypeFactory());
}

但这无助于避免这些警告。这里有什么问题吗？

在此先感谢您，并向蒂姆致以最诚挚的问候。

我用来自 dbunit faq 的信息解决了这个问题.只需设置数据类型工厂属性即可使警告消失。

    Connection dbConn = template.getDataSource().getConnection();

    IDatabaseConnection connection = new DatabaseConnection(dbConn, "UTEST", false);

    DatabaseConfig dbConfig = connection.getConfig();

    // added this line to get rid of the warning
    dbConfig.setProperty(DatabaseConfig.PROPERTY_DATATYPE_FACTORY, new OracleDataTypeFactory());
