[Groovy] Class GrailsServletContextReferenceRule

java.lang.Object
  org.codenarc.rule.AbstractAstVisitorRule
      groovy.org.codenarc.rule.grails.GrailsServletContextReferenceRule

class GrailsServletContextReferenceRule
extends AbstractAstVisitorRule

Rule that checks for references to the servletContext object from within Grails controller and taglib classes.

This rule is intended as a "governance" rule to enable monitoring and controlling access to the servletContext from within application source code. Storing objects in the servletContext may inhibit scalability and/or performance and should be carefully considered. Furthermore, access to the servletContext is not synchronized, so reading/writing objects from the servletConext must be manually synchronized, as described in The Definitive Guide to Grails (2nd edition).

Enabling this rule may make most sense in a team environment where team members exhibit a broad range of skill and experience levels. Appropriate servletContext access can be configured as exceptions to this rule by configuring either the doNotApplyToFilenames or doNotApplyToFilesMatching property of the rule.

This rule sets the default value of applyToFilesMatching to only match files under the 'grails-app/controllers' or 'grails-app/taglib' folders. You can override this with a different regular expression value if appropriate.
