setProperty in XmlConfiguration escapes backslashes
---------------------------------------------------
Key: CONFIGURATION-440
URL: https://issues.apache.org/jira/browse/CONFIGURATION-440
Project: Commons Configuration
Issue Type: Bug
Components: Build
Affects Versions: 1.6
Environment: Windows 7
Reporter: B
Fix For: 2.0
When setPropery sets a new value that has backslashes (like path), backslashes
are escaped. When that value is loaded again, all backslashes are duplicated.
public class XmlConfigurationTest {
private static final String XML_CONFIGURATION_PATH =
"resources/xml/config.xml";
private static final String PATH1 = "c:\\temp\\path\\file.txt";
private static final String PATH2 = "c:\\temp1\\path1\\file1.txt";
private static final String PATH3 = "c:\\temp2\\path2\\file2.txt";
@Test
public void testXmlConfiguration() throws IOException {
File resourceFile = null;
try {
assertNotNull(_bundleContext);
resourceFile = new File(SystemUtils.getTargetDirectory(),
XML_CONFIGURATION_PATH);
assertTrue(resourceFile.getParentFile().mkdirs());
String value = null;
XMLConfiguration configuration = new XMLConfiguration();
configuration.setExpressionEngine(new XPathExpressionEngine());
configuration.setDelimiterParsingDisabled(true);
configuration.addProperty(" key1", PATH1);
configuration.setProperty(" key2", PATH2);
configuration.save(resourceFile);
/* All values are saved with non escaped backslashes */
value = configuration.getString("key1");
assertEquals(value, PATH1);
value = configuration.getString("key2");
assertEquals(value, PATH2);
/*
* Set again same property with different value. Setting property
* with this configuration will escape backslashes. Even though
* assert will pass, path with escaped backslashes will be written
* in a file (don't know if it is setProperty or save that is
causing troubles).
*/
configuration.setProperty(" key2", PATH3);
configuration.save(resourceFile);
value = configuration.getString("key2");
assertEquals(value, PATH3);
/*
* Create new configuration and load values from previously saved
* file.
*/
XMLConfiguration newConfiguration = new XMLConfiguration();
newConfiguration.setExpressionEngine(new XPathExpressionEngine());
newConfiguration.setDelimiterParsingDisabled(true);
newConfiguration.load(resourceFile);
/*
* At this point, configuration will load escaped backslashes, and
* the test will fail.
*/
value = newConfiguration.getString("key2");
assertEquals(value, PATH3);
} catch (Throwable e) {
e.printStackTrace();
fail(e.getLocalizedMessage());
} finally {
/*
* Delete resource file
*/
resourceFile.delete();
}
}
}
