I need to read a file from the file system and load the entire contents into a string in a groovy controller, what's the easiest way to do that?

String IndexingThe individual character in a string can be accessed by its position. This is given by an index position. String indices start at zero and end at one less than the length of the string. Groovy also permits negative indices to count back from the end of the string.
Since the path changes machine to machine, you need to use a variable / project level property, say BASE_DIRECTORY, set this value according to machine, here "/home/vishalpachupute" and rest of the path maintain the directory structure for the resources being used. Regards, Rao.
String fileContents = new File('/path/to/file').text If you need to specify the character encoding, use the following instead:
String fileContents = new File('/path/to/file').getText('UTF-8') If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
