Question

我正在尝试使用dbunit将XML文件加载到mySql，我的FlatXmlDataSet显示

“注意：此元素既没有附加源也没有附加Javadoc，因此找不到Javadoc”

但是获得AsserionFailedError：null

dbunit版本 - ＆gt; 2.4.9 mySql - ＆gt; 5.2

public class DbUnitSampleTest extends TestCase {

public static final String TABLE_LOGIN ="login";
private FlatXmlDataSet loadedDataSet;

protected IDatabaseConnection getConnection() throws Exception
{
Class.forName("com.mysql.jdbc.Driver");
Connection jdbcConnection =DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");

return new DatabaseConnection(jdbcConnection);
}

@SuppressWarnings("deprecation")
protected IDataSet getDataSet() throws Exception
{               
        loadedDataSet = new FlatXmlDataSet(this.getClass().getClassLoader().getResourceAsStream("input.xml"));

        return loadedDataSet;
}   

public void testCheckLoginDataLoaded() throws Exception
{       
assertNotNull(loadedDataSet);
int rowCount = loadedDataSet.getTable(TABLE_LOGIN).getRowCount();
TestCase.assertEquals(2, rowCount);
}
}

错误：

问题出在这里

loadedDataSet = new FlatXmlDataSet(this.getClass().getClassLoader().getResourceAsStream("input.xml"));

DBUnit的错误消息很少。问题是资源加载器找不到您的input.xml文件。尝试将它分开。

InputStream is = this.getClass().getClassLoader().getResourceAsStream("input.xml")
if(is != null)
   loadedDataSet = new FlatXmlDataSet(is);
else
   System.out.println("Can't find input.xml :(");

从那里你应该能够找到无法找到input.xml的原因。

java无法使用FlatXmlDataSet读取XML文件
