I have a Java Properties
object that I load from an in-memory String
, that was previously loaded into memory from the actual .properties
file like this:
this.propertyFilesCache.put(file, FileUtils.fileToString(propFile));
The util fileToString
actually reads in the text from the file and the rest of the code stores it in a HashMap
called propertyFilesCache
. Later, I read the file text from the HashMap
as a String
and reload it into a Java Properties
object like so:
String propFileStr = this.propertyFilesCache.get(fileName);
Properties tempProps = new Properties();
try {
tempProps.load(new ByteArrayInputStream(propFileStr.getBytes()));
} catch (Exception e) {
log.debug(e.getMessage());
}
tempProps.setProperty(prop, propVal);
At this point, I've replaced my property in my in-memory property file and I want to get the text from the Properties
object as if I was reading a File
object like I did up above. Is there a simple way to do this or am I going to have to iterate over the properties and create the String
manually?
public static String getPropertyAsString(Properties prop) {
StringWriter writer = new StringWriter();
prop.list(new PrintWriter(writer));
return writer.getBuffer().toString();
}
