爲dbunit導入/導出xml

Question

我們如何輕鬆導入/導出dbunit可以採用以下格式的數據庫數據？

<dataset> 
    <tablea cola="" colb="" /> 
    <tableb colc="" cold="" /> 
</dataset> 

我想找到一種方法，從導出數據庫中現有的數據爲我的單元測試。

Answer 1

藍色，這會讓你以你想要的格式導出你的數據。

public class DatabaseExportSample { 
    public static void main(String[] args) throws Exception { 
     // database connection 
     Class driverClass = Class.forName("org.hsqldb.jdbcDriver"); 
     Connection jdbcConnection = DriverManager.getConnection(
       "jdbc:hsqldb:sample", "sa", ""); 
     IDatabaseConnection connection = new DatabaseConnection(jdbcConnection); 

     // partial database export 
     QueryDataSet partialDataSet = new QueryDataSet(connection); 
     partialDataSet.addTable("FOO", "SELECT * FROM TABLE WHERE COL='VALUE'"); 
     partialDataSet.addTable("BAR"); 
     FlatXmlDataSet.write(partialDataSet, new FileOutputStream("partial.xml")); 

     // full database export 
     IDataSet fullDataSet = connection.createDataSet(); 
     FlatXmlDataSet.write(fullDataSet, new FileOutputStream("full.xml")); 

     // dependent tables database export: export table X and all tables that 
     // have a PK which is a FK on X, in the right order for insertion 
     String[] depTableNames = 
      TablesDependencyHelper.getAllDependentTables(connection, "X"); 
     IDataSet depDataSet = connection.createDataSet(depTableNames); 
     FlatXmlDataSet.write(depDataSet, new FileOutputStream("dependents.xml")); 
    } 
}

導出已經回答。 要完成答案，您可以將導入將數據集導入數據庫。 connection類型爲IDatabaseConnection。 馬克羅賓遜先前的答案（出口）包含如何創建數據庫連接的代碼。

FlatXmlDataSet dataSet = new FlatXmlDataSet(new FlatXmlProducer(new InputSource(new FileInputStream("dataset.xml")))); 
DatabaseOperation.CLEAN_INSERT.execute(connection, dataSet);
