将数据集显示为xml文件,在DBunit中给出错误

Question

大家好我正在使用dbunit.我正在尝试将db的datset导出到xml文件中.

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"));

    }
}

但它给出了这样的错误:

Exception in thread "main" org.dbunit.dataset.DataSetException: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'user'.

我的猜测是user你的数据库中有一个表.但它user是MSSQL中的保留关键字.DBUnit创建一些查询,如:

SELECT * FROM user;

但这会产生您所看到的错误.相反,DBUnit必须创建一个类似的查询:

SELECT * from [user];

我想你可以使用DBUnit 的Escape模式配置设置来解决这个问题.我自己没试过,但这样的事情应该有效:

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

我希望这有帮助!:)
