title: Grails: disable Spring Security Core on certain paths
body: <p>How do I set up Spring Security Core in a way that calls to a certain pattern (such as /api/**) are not filtered?</p>
  
  <pre><code>grails.plugins.springsecurity.filterChain.chainMap = [
  '/api/**': '',
  '/**': 'JOINED_FILTERS',
  ]
  </code></pre>
  
  <p>doesn't work, since it will try to resolve the bean ''.</p>
  
  <p>Is there anything other than the nasty workaround with 'JOINED_FILTERS,-filter1,-filter2,...'</p>
  
  <p>How are static resources being excluded from Spring Security?</p>
