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?

Note that this is [no longer the default behavior in commons-configuration 2](https://commons.apache.org/proper/commons-configuration/userguide/upgradeto2_0.html#Accessing_Configuration_Properties). — David Moles, Sep 27 '19 at 19:18

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

Note that if you are using profiles with different config files you need to escape twice these ',' commas with '\\,' because the strings are parsed twice. – bogdan.rusu Mar 22 '16 at 12:51
@bogdan.rusu Double escaped worked for us. Thanks! – David Velasquez Jun 20 '22 at 19:16

Check Javadoc. You have to setDelimiterParsingDisabled(true) to disable parsing list of properties.

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);

PropertiesConfiguration interprets ',' as a value separator.

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
