title: How to map an URL having querystring parameters in urlmapping.groovy?
body: <p>I am new to Grails/Groovy. Please bear with me if this is a silly question.</p>
  
  <p>I am trying to map an URL having querystring parameters in <code>urlmapping.groovy</code>, something like,</p>
  
  <pre><code>"/rest/employees?empno=123&amp;dept=delivery"(controller:"employees", action="emp")
  </code></pre>
  
  <p>The values <code>123</code> and <code>delivery</code> are dynamic values. In other words, this could be anything that the user can use.</p>
  
  <p>Apparently this syntax is not correct. What is the right way to achieve this?</p>
