Checking if a string contains a particular substring in Velocity

java string substring velocity
Victoria picture Victoria · Nov 5, 2012 · Viewed 30.7k times · Source

In Velocity I have a variable called $url which contains the following string: [ContentId(2.7507), ContentId(2.7508), ContentId(1.44551)]

I want to check if that string contains the substring 1.44551.

This is the code I've written so far, but for some reason it's returning False:

#if($url.contains("1.44551"))
<p>The article content id is 1.44551</p>
#else
<p>The article content id isn't 1.44551</p>
#end

I would expect this to be returning True, as the 1.44551 substring is present in the $url variable. Please can someone tell me where I'm going wrong?

Velocity holds values as Objects in context map.

If you want to execute String method, add toString to make sure you execute on String the contains method:

 #if($url.toString().contains("1.44551"))
<p>The article content id is 1.44551</p>
#else
<p>The article content id isn't 1.44551</p>
#end
