Method Detail

resolveValue

public static String resolveValue(String value)

Resolves the variable pattern '${}' to a real value if present in the system properties.

Supports default values using '${placeholder:-default} if placeholder is undefined, supports hidden fields using '${placeholder:-*HIDDEN*}' which prevents the value being logged for security reasons, also supports substrings before or/and after value which should be resolved 'value${placeholder}' or '${placeholder}value' or 'value${placeholder}value'.

The system properties should include the environment variables and jvm startup properties ('-D').

Parameters:

value - The potential variable value to resolve

Returns:

The resolved value, if the input is not a (valid) variable or not present it returns the original value.
