title: Meaning of "params" in @RequestMapping annotation?
body: <p>I am aware of @RequestMapping annotation which is used in Spring MVC based application.</p>
  
  <p>I came across this piece of code:</p>
  
  <pre><code>@RequestMapping(method = POST, params = {"someParam"})
  </code></pre>
  
  <p>I understood the <code>method</code>. However I don't know what <code>params</code> means? Before this I never had seen anything which passed params to this annotation.</p>
  
  <p>Can anyone help in understanding this?</p>
