大家好,我正在使用dbunit。我正在尝试将db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$2004"); IDatabaseConnection connection = new DatabaseConnection( jdbcConnection ); // full database export IDataSet fullDataSet = connection.createDataSet(); FlatXmlDataSet.write(fullDataSet, new FileOutputStream("full.xml")); } }
但是它给出了这样的错误:
Exception in thread "main" org.dbunit.dataset.DataSetException: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'user'. at org.dbunit.database.DatabaseDataSet.getTable(DatabaseDataSet.java:323) at org.dbunit.database.DatabaseTableIterator.getTable(DatabaseTableIterator.java:89) at org.dbunit.dataset.stream.DataSetProducerAdapter.produce(DataSetProducerAdapter.java:83) at org.dbunit.dataset.xml.FlatXmlWriter.write(FlatXmlWriter.java:124) at org.dbunit.dataset.xml.FlatXmlDataSet.write(FlatXmlDataSet.java:378) at DatabaseExport.main(DatabaseExport.java:23) Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'user'. at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:197) at com.microsoft.sqlserver.jdbc.SQLServerStatement.getNextResult(SQLServerStatement.java:1493) at com.microsoft.sqlserver.jdbc.SQLServerStatement.doExecuteStatement(SQLServerStatement.java:775) at com.microsoft.sqlserver.jdbc.SQLServerStatement$StmtExecCmd.doExecute(SQLServerStatement.java:676) at com.microsoft.sqlserver.jdbc.TDSCommand.execute(IOBuffer.java:4575) at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(SQLServerConnection.java:1400) at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeCommand(SQLServerStatement.java:179) at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeStatement(SQLServerStatement.java:154) at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeQuery(SQLServerStatement.java:611) at org.dbunit.database.AbstractResultSetTable.<init>(AbstractResultSetTable.java:110) at org.dbunit.database.ForwardOnlyResultSetTable.<init>(ForwardOnlyResultSetTable.java:59) at org.dbunit.database.CachedResultSetTableFactory.createTable(CachedResultSetTableFactory.java:60) at org.dbunit.database.DatabaseDataSet.getTable(DatabaseDataSet.java:319) ... 5 more
我的猜测是user您的数据库中有一个表。但是user是MSSQL中的保留关键字。DBUnit创建一些查询,例如:
user
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];
我认为您可以使用DBUnit 的转义模式配置设置来解决此问题。我自己没有尝试过,但是类似的东西应该可以工作:
connection.getConfig().setProperty(DatabaseConfig.PROPERTY_ESCAPE_PATTERN , "[?]");
我希望这有帮助!:)
