title: Jsonpath with Jackson or Gson
body: <p>I am getting a big json document and i want to parse only some part of it to my java classes. I was thinking to use something like jsonpath to extract partial data from it instead of creating entire hierarchy of java classes. </p>
  
  <p>Does Jackson or Gson support jsonpath in any way? If yes, can you please provide me some examples or point to another standard library for this purpose?</p>
  
  <p>For example lets say i have a below document and i want to extract only below data from it in my java classes:</p>
  
  <p>$.store.book[0] - Only first book
  $.store.bicycle.price - price of bicycle</p>
