将数据集显示为在DBUnit中发生错误的xml文件

Question

大家好我正在使用dbunit。我试图将数据库的数据库导出到一个XML文件。

import java.sql.Connection; 
import java.sql.DriverManager; 
import org.dbunit.database.DatabaseConnection; 
import org.dbunit.database.IDatabaseConnection; 
import org.dbunit.dataset.IDataSet; 
import org.dbunit.dataset.xml.FlatXmlDataSet; 
import java.io.FileOutputStream; 

public class DatabaseExport 

{ 
    public static void main(String[] args) throws Exception 
    { 
     Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
     DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver()); 
     Connection jdbcConnection = DriverManager.getConnection("jdbc:sqlserver://172.26.37.113:1433;DatabaseName=def_config","sqladmin_","halloween$2004"); 
     IDatabaseConnection connection = new DatabaseConnection(jdbcConnection); 
     // full database export 
     IDataSet fullDataSet = connection.createDataSet(); 
     FlatXmlDataSet.write(fullDataSet, new FileOutputStream("full.xml")); 

    } 
} 

但它给这样的错误：

Answer 1

我的猜测是，你有一个表在你的数据库称为user。但user是MSSQL中的保留关键字。 DBUnit创建一些查询，如：

SELECT * FROM user; 

但是，这会产生您所看到的错误。相反DBUnit的有可能创造像查询：

SELECT * from [user]; 

我想你可以使用这个DBUnit的的Escape pattern配置设置修复。我没有自己尝试，但这样的事情应该工作：

connection.getConfig().setProperty(DatabaseConfig.PROPERTY_ESCAPE_PATTERN , "[?]"); 

我希望这可以帮助！ :)

感谢您的上述解决方案。这是实际的解决方案。

import java.sql.Connection; 
import java.sql.DriverManager; 
import org.dbunit.database.DatabaseConfig; 
import org.dbunit.database.DatabaseConnection; 
import org.dbunit.database.IDatabaseConnection; 
import org.dbunit.dataset.IDataSet; 
import org.dbunit.dataset.xml.FlatXmlDataSet; 
import java.io.FileOutputStream; 

public class DatabaseExport 
{ 
    public static void main(String[] args) throws Exception 
    { 
     Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
     DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver()); 
     Connection jdbcConnection = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;DatabaseName=def_config","user","passwd$2004"); 
     IDatabaseConnection connection = new DatabaseConnection(jdbcConnection); 
     connection.getConfig().setProperty(DatabaseConfig.PROPERTY_ESCAPE_PATTERN , "[?]"); 
     // full database export 
     IDataSet fullDataSet = connection.createDataSet(); 
     FlatXmlDataSet.write(fullDataSet, new FileOutputStream("C:/full.xml")); 
    } 
}

如果你要导出的数据集usnig蚂蚁，我们可以这样做

<dbunit driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" url="jdbc:sqlserver://localhost:1433;DatabaseName=config1" userid="user" password="passwd$2004" escapePattern="[?]" datatypeFactory="org.dbunit.ext.mssql.MsSqlDataTypeFactory">
<compare src="C:/export.xml"/> </dbunit>
