java - 将数据集导出到 XML 文件，在 DBunit 中出现错误

Question

大家好，我正在使用 dbunit。我正在尝试将数据库的数据集导出到 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"));

    }
}

但是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'.

我的猜测是您的数据库中有一个名为 user 的表。但是 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 必须创建如下查询:

SELECT * from [user];

我想你可以使用 Escape pattern 来解决这个问题DBUnit 的配置设置。我自己没有尝试过，但这样的事情应该可行:

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

希望对您有所帮助! :)
