title: Cut the json string in to two different json string in java
body: <p>I am pretty new to json and normally donot use do much coding.
  I want a service which takes below json string as input</p>
  
  <pre><code>{
      "var": "test11",
      "_env": {
          "activation": "wm6a93e3a80-0307-12cc-96e6-d79883bf841a",
          "uuid": "48cdc2d0-0212-11e6-8315-d79883bf841a",
          "eventID": 49167,
          "recvTime": "Thu Apr 14 00:27:03 PDT 2016"
      }
  }
  </code></pre>
  
  <p>and spit out output as</p>
  
  <pre><code>{
      "var": "test11"
  } 
  </code></pre>
  
  <p>and </p>
  
  <pre><code>{
      "_env": {
          "activation": "wm6a93e3a80-0307-12cc-96e6-d79883bf841a",
          "uuid": "48cdc2d0-0212-11e6-8315-d79883bf841a",
          "eventID": 49167,
          "recvTime": "Thu Apr 14 00:27:03 PDT 2016"
      }
  }
  </code></pre>
  
  <p>The is just an example. It can contain more objects in json string and _env won't always appear at the end.</p>
  
  <p>Is there any simple way to achieve using jackson API ?</p>
