The JSON Exclusion Marshaller is a Grails plugin that adds a convenience method to the Grails JSON converter for excluding class properties from the JSON converter's output.
+public static excludeFor*(Class class, List<String> propertiesToExclude)
+**excludeFor*(...)** is a synthesized method. There are no restrictions or conventions for what you put in the place of the * wildcard, though it must be a valid method name.
+For instance, these are all valid:
+As long as the method name you choose starts with "excludeFor", you're good to go.
+* class - The class of the object you will be excluding properties from.
+* propertiesToExclude - A list of the properties you want to be excluded from the JSON converter's output.
