Question

我正在尝试使用DBUnit从AS400导出数据并将其导入HSQLDB数据库以进行JUnit测试，但是，似乎不会导出/导入数据类型信息。似乎所有东西都被导出（因此将被导入）作为CDATA。有人能告诉我在哪里可以找到答案吗？

我已成功构建并运行其中一个示例：

public static void main(String[] args) throws Exception
{
    // database connection
    Class driverClass = Class.forName("com.ibm.as400.access.AS400JDBCDriver");
    Connection jdbcConnection = DriverManager.getConnection("jdbc:as400://myserver;libraries=MYLIB", "user", "password");
    IDatabaseConnection connection = new DatabaseConnection(jdbcConnection);

    // partial database export
    QueryDataSet partialDataSet = new QueryDataSet(connection);
    partialDataSet.addTable("TABLE1");
    partialDataSet.addTable("TABLE2");
    FlatXmlDataSet.write(partialDataSet, new FileOutputStream("flatpartial_as400.xml"));
    FlatDtdDataSet.write(connection.createDataSet(), new FileOutputStream("flatdtd_as400.dtd"));
    XmlDataSet.write(partialDataSet, new FileOutputStream("partial_as400.xml"));

例如，这给了我以下输出：

<?xml version='1.0' encoding='UTF-8'?>
<dataset>
  <TABLE1/>
  <TABLE2 ADDRESS_ID="1" ADDRESS_TYPE="1" ADDRESS_DESCRIPTION="Billing Address          "/>
  <TABLE2 ADDRESS_ID="2" ADDRESS_TYPE="2" ADDRESS_DESCRIPTION="Delivery Address         "/>
  <TABLE2 ADDRESS_ID="3" ADDRESS_TYPE="3" ADDRESS_DESCRIPTION="Owner Address            "/>
  <TABLE2 ADDRESS_ID="4" ADDRESS_TYPE="4" ADDRESS_DESCRIPTION="Owner Previous Address   "/>
  <TABLE2 ADDRESS_ID="5" ADDRESS_TYPE="5" ADDRESS_DESCRIPTION="Store Address            "/>
</dataset>

以下是生成的DTD片段：

<!ELEMENT TABLE2 EMPTY>
<!ATTLIST TABLE2
    ADDRESS_ID CDATA #REQUIRED
    ADDRESS_TYPE CDATA #REQUIRED
    ADDRES_DESCRIPTION CDATA #REQUIRED
>

第一个字段应为DECIMAL（10,0），但它是CDATA。显然，从数据完整性的角度来看，这将是一个问题。在调试器中，我可以看到类型信息正在使其成为DBUnit包（ADDRESS_ID字段在代码中是DECIMAL。）但是该信息并未使其成为文件的XML DTD。

感谢任何帮助...

也许它会有所帮助：为要导入的表生成dtd文件

private static void generateDTD(String fileName,IDatabaseConnection connection,
        String[] tablesToExport) throws IOException, DataSetException,
        SQLException, FileNotFoundException {
    FlatDtdDataSet.write(connection.createDataSet(tablesToExport), new FileOutputStream(fileName));
}

然后在构建器

中设置它

FlatXmlDataSetBuilder builder = new FlatXmlDataSetBuilder();
        builder.setMetaDataSetFromDtd(new FileInputStream(schemaFile));

在DBUnit中导出/导入数据类型？
