apache commons configuration loads property until "," character

Question

I want to load configuration (apache commons configuration) from a properties file. My program is:

PropertiesConfiguration pc = new PropertiesConfiguration("my.properties");
System.out.println(pc.getString("myValue"));

In my.properties I have

 myValue=value,

with comma

When I run program the output is value, not value, with comma. Looks like value is loaded until , character.

Any ideas?

Answer 1

That behavior is clearly documented, i.e., that PropertiesConfiguration treats a value with a comma as multiple values allowing things like:

fruit=apples,banana,oranges

to be interpreted sensibly. The fix (from the doc) is to add a backslash to escape the comma, e.g.,

myKey=value\, with an escaped comma

Answer 2

Actually propConfig.setDelimiterParsingDisabled(true) is working, but you must load the config file after this setting, for example:

propConfig = new PropertiesConfiguration();
propConfig.setDelimiterParsingDisabled(true);
propConfig.load(propertiesFile);

Settings won't work if your code like is:

propConfig = new PropertiesConfiguration(propertiesFile);
propConfig.setDelimiterParsingDisabled(true);

Answer 3

PropertiesConfiguration interprets ',' as a value separator.

Answer 4

If you put \ before the ,, you escape it, and you can read the value

Example:

myValue=value\, with comma

You read = value, with comma without problems
